Fifteen days after Little Lao was born.

The cool weather of spring was being gradually replaced by the cloudless-sky and scorching sun of summer.

The workshop and forge outside the cave were functioning properly and Lin got busy most of the day on directing his father on what to do.

Right now they're melting the bones under intense fire that reached over one-thousand two-hundred degrees Celsius while the molds are ready to be filled with the processed hot liquid anytime now.

He saw his father return littered with wounds more than once from his hunting journeys and thought it's about time to make him some protective-armor and to arm him with proper weapons.

Inside the cave the space was separated into a playground for the tigers to the far left if you’re entering and right next to it is the parents room which inlayed with triple layers of wooden walls with hay in-between to prevent the erotic sounds of his mother from seeping through. Lin was frowning when he added the extra layer and Lily and his mother kept giggling non-stop because they both knew the reason for his extra trouble. Then next to the parent’s bedroom is the bathroom followed by an empty space for the kitchen which has nothing inside it save for a table and a few chairs in the middle. Lin plans on adding all the utensils, kitchenware, etc. after his father returns from the next hunting journey. Next to the kitchen is the room for the twins with another bed for Lao to use in the future then the living area right ahead of the cave entrance and decorated with the chairs and couches Lin made with his father and the most prominent piece  of furniture is Lily's rocking chair.

Exiting the cave you'll find the workshop to the left and to the right there's another empty space where Lin started to grow some of the seeds. After Lily asked for their garden to be nearby and within manageable-distance for herself and her mother Lin changed his previous plans and had his father bring the soil from down the mountain instead then the cave-man plowed the earth with his hands after its thickness was appropriate for the plant’s root-system to spread.

Finally Lin and his father created a simple pavilion next to this plot of farmland then added a table and a comfortable set of chairs beneath it in-case the family felt like eating in open-air then they can go outside to enjoy the view.

“Dad, this is good enough. Now pour it in the molds, wait!... I told you -like a thousand times- to stand, behind this rock, when you do it, are you looking for a quick death? come, stand here, and... be careful. This, is extremely hot, understand? hot! now pour."

Lin rolled his eyes at his idiotic father because the cave-man thinks that his fur and hay shoes and clothes can protect him from the hot liquid of melted bones.

Shouting and screaming became the normal thing for Lin these days and sometimes his voice will be clogged or stuffy from extreme shouting at his old man all day and the next day his throat will be sore.

Luckily the caveman became obedient after suffering every time he ignored the orders of his little-one now he learned to follow his directions even though he couldn't understand most of his intentions.

Whenever the little-one raised his voice then that became like an alarm-bell ringing in the cave-man's head 'freeze mother f***er!'

Lin is someone who never had to shout or yell before in either of his lives and if the great-sage Lin was ever recorded in an argument with anyone then it would always be filled with him softly talking and smiling to the degree of irritating.

Lily was enjoying that different side of her brother and took care of the rest of the matters while he’s busy.

After his father completed filling-out all the prepared molds Lin gave him his reward after a good day’s work which is a wooden-gourd full of liquor.

For the last three months Lin didn't stop making more liquor from the different materials his father gathered and the cave-man would spend all days working his hardest just for that single moment when he gets rewarded by his small-one.

When he started working with his little-one he tried to slack and still earn his reward anyway then he got punished by his woman instead when the little-bug ratted him out.

Then he tried to spy on the little-bug and learn where exactly is he hiding the liquor and again he came-up empty after finding-out that the liquor would only magically appear when he does a "good job for the day" and listens to his little-one’s orders.

Lily was having a good time fooling her dad with her brother and thinks that the look on her dad's face when he tried to figure out where the liquor is coming from is worth an Oscar.

His hidden fear of the little-bug's abilities made the idiot father more obedient when he worked and gradually he started to even stop and inquire with his eyes every now and then to check and see if it's okay to continue.

“Let's go dad, did you know? today is mine and Lily’s birthday! that’s why I'll let you drink some more of the liquor you love so much.”

Lin gave a last cursory check on the molds with his eyes to make sure everything is perfectly fine then walked back towards the cave to take a shower while notifying his father.

His mother was told since yesterday to grind some wheat seeds and prepare more flour and now that they have the eggs their birthday-cake is only missing some milk.

'Don't you ever think about it!' Lin glared at Lily when he saw her frowning in front of the ingredients table and she just shrugged in return.

Lily was permitted to eat candy once every two days now and the cake Lin is going to make is specifically for their mother and father to consume while only a small piece is allowed for Lily.

He didn't need to explain to her the benefits of breastfeeding for babies and for the next six months their main source of nutrition will remain being their mother's breast-milk and only after that period will they start adding small portions of food to their menu until they gradually and completely exchange breast-milk with normal food during the remaining six months of their second year.

By the time they reach their second birthday that will be the mark of their graduation from breastfeeding all-together.

Lin was feeling a hundred percent sure that someone like Lily would mostly apply for an extension on her breastfeeding duration if she could because she is that strange a person.

After helping his mother make one perfect cake the five members of the family sat outside under the pavilion  and Lin and Lily started by singing the cheerful birthday song then let their mother join them in blowing-out the single candle in the middle.

“Thanks mom, you should be really proud. After all... you gave birth to cute me.”

Lily shamelessly kissed her mother's lips instead of her cheeks to show her thanks and she tried to force her tongue inside too.

“Mmnh... ah!...”

Lin's mother blushed slightly when she saw Lin glaring at his twin-sister for what she just did in front of him and she pushed her mischievous daughter away at arm’s length.

“Li... i'n...”

Then he heard his mother struggling with pronouncing his name then smiling at him.

“Yes mom! that’s my name, Lin and you just said it, good job mom you're very sweet. I could never ask for a better gift on my birthday.”

Lin kissed his mother's hand and patted her while the wide smile remained on his face for five minutes.

Lin's father was blushing from the strong liquor Lin offered him this time but don’t let the appearances fool you because the cave-man’s intoxication-tolerance advanced greatly since the first incident when he tasted the blueberries-wine.

Now he learned to enjoy each session by drinking at his own pace.

Next day his father left while wearing a full-body armor made from melted bones and at his hand was a two-handed long and heavy sword with both sides having blunt edges and snaking-spikes instead of sharp edges of a normal sword or blade! since the father proved to be a mace and blunt-weapon expert and blunt-weapons suited his style best. Lin knew that it would be utterly useless to give his father a sharp weapon because the cave-man might end-up harming himself instead.

He made the sword at the right length to be suitable for his father’s height and arm-reach but increased its weight and thickness to match his father's previous stone mace! he only added snaking spikes at the edges in the end to cause a bleeding-effect on top of the blunt-weapon’s crushing effect.

The body-armor and helmet were both made with specific focus on maintaining flexibility while making swallowing this cave-man a hellish experience for any large-sized predator! the amount of spikes and pointy parts coming from the head, shoulders chest, back, abdomen, sides, arms, elbows, knees, legs, and ankles, was more than five-hundred spikes of various lengths.

If you’re asking how did that armor fare in Lin’s pressure test? Lin made sure to make these bone plates protecting his father's body capable of withstanding triple the usual pressure of similar bone-armor while maintaining half a grade lighter! and the reason Lin went through such trouble working on this bone material in the first place is because he wanted to grow up with a father in this life and he wouldn't allow some large-sized beast to rob him from this experience in this life.

A dozen short javelins were given to the father for him to use on fast animals and Lin only hoped his father truly understand his intentions of giving him these throwing-weapons in the first place.

He made his father try throwing one before he left and his aim was totally off target still he got the same ridiculous amount of strength like always.

That short javelin punctured two rocks with the thickness of five meters each then continued its path for almost five-hundred more meters before creating a wide hole down the mountain! the cloud of dirt was pretty large like if some hand-grenade just exploded down there.

The only one being happy to witness that sight was Lily clapping like she just watched the perfect show, she nodded in approval then gave her father the signal to come close then rewarded him with a big wet kiss on his cheek while avoiding the dangerous spikes on his armor then sending him away with a wave of her hand until he left their sight.

Returning to having nothing to do with his days Lin and Lily took care of their little brother Lao with their mother and spent the days teaching her how to talk or wrestling the two tiger cubs.

It was awful for Lin being upside-down wasn't fun for a great-sage since the natural order of life is the grown-ups teaching their children the way of living and not the other way around.

Then after twenty days his father returned.

Normally he'll be gone for a month or more and now he returned after only twenty days with triple the usual amount of food.

A deer a bear were loaded on the father’s slide next to lots of bags filled with seeds and fresh fruits! one large wooden container full of glistening honey which is something Lin taught him how to gather if found and how to keep the annoying flying things -that stings like bad- away with smoke and double the previous amount of eggs and one large bird that he managed to luckily hit with a javelin as it would seem.

First thing the caveman did when he returned was to take-off his armor that protected him from these four-legged enemies! throw away the fantastic weapon that helped him beat up any competition in just three or four strikes then give his little-bug a great hug.

“Eww! you're covered in blood and gore, dad let go... I feel like I'll puke, quickly... emphg... blurgh...”

Lin felt the world swirling in front of his eyes when his father stuffed his face in the aftermath of more than twenty days without showering mixed with the smell of unwashed blood and gore resulting from multiple battles his father experienced in his hunting journey! after trying very hard not to be rude and stopping himself from vomiting on his biological father the cave-man didn't get the message and kept giving him rough love-rubs while shaking him between his palms.

Simply because the cave-man’s alarm system depends on high volume screaming or shouting from his son he didn’t notice! great-sage Lin wasn't able to breathe normally in his current state of nausea and could barely speak. How would he shout or raise his voice?

His stomach got forcefully emptied on his father's face and body and only after vomiting twice did Lin feel his discomfort disappear! still he was feeling very ashamed of himself because of what he did.

“Hahaha... this is just hilarious, keep going, by all means don't stop because of me. Mom... come quick, this sight is worth gold. Hurry, let go of the bear it's already dead! such a strange woman you’re to still think of food while there’s such fun to watch instead.”

Lily fell on her butt and kept stomping her feet on the ground when she saw the sight.

Lin's mother face darkened in anger at her man's sight covered in undigested milk from Lin’s belly which originated her chest! snatching Lin from her man’s hand she hugged him to her chest tightly then went towards the bathroom while dragging her man with her free hand behind her by the ear.

“Hahahaha... dad, looks like today is going to be the day you finally know who's the true boss in this cave.”

Lily's voice entered Lin's ear and he frowned slightly.

He had no problem with his parents having more children but to keep getting pregnant without giving his mother sufficient time for her body to recover from previous pregnancy is dangerous.

Even if his mother is a cave-woman version with stronger body and vitality! Hidden-injuries will be critical and currently Lin isn't supported or equipped with proper medical equipment to solve them if they happened.

By the time he noticed signs of them then it will be too late for regrets.

'Looks like I'll have to give her the "sex-talk" and how to take precautions against pregnancy' Lin sighed and hung his head down in embarrassment.

After getting a quick shower Lin quickly found himself being "the elephant in the bathroom" when he actively -and for the first time- stopped his parents from having sex! Lin really wished for a hole to hide in it because the embarrassment was killing him.

His mother seemed to understand the gist of his reason and blushed slightly then carried Lin out of the bathroom after wearing her clothes! while the father –with a raging erection- got gifted a gourd of a very strong liquor instead and he unwillingly accepted the bribe.

He kept muttering something when he looked at his woman leave with his boy towards the pavilion outside then he went to bully the two little tiger cubs and sipped on his liquor while doing it.

Lily was having the best time of her life while she watched her brother explain to her mother how to stop her man from ejaculating inside and what to do if it happens.

“Bfffft...”

Lily couldn’t stop herself from laughing when she saw her mother nod with a smile on her face to convey that she understood what Lin just spent a long time saying in detail while adding sign-language to the mix to ensure his message is clear enough for his mother.

“Lily! you dare play me for a fool?”

How could Lin not read between the lines? clearly Lily tricked him into having this chat with his mother by manipulating his parents just to have her sick-fun in watching him embarrass himself which is something very much to her satisfaction.

From his mother's smile he saw amusement and love beyond measure mixed with a sly shade of apology in her eyes.

Lily already told her earlier about the matter of birth-prevention and because Lin was too embarrassed to look his mother in the eyes he missed the signs of body-language because he kept looking away most of the time he spoke.

“Heh... yes I did, and yes I dare. Because like you said, right now... you're just a fool in my eyes. You're no great-sage Lin in this life, there's no ministry, or a world which is depending on you to save it. You're just a kid, a sad kid who’s missing-out on the most important thing, Living. You're always uptight and strict, like just a boring mule tied to a windmill and never gets tired of spinning to the degree which makes me sick to my stomach. You're always seeking to save, seeking to protect or help. So what? if we're alone, if we’re poor or dirty and behind the ages of civilization. What can your goody-two-shoes do? huh! what can your lonely small hands do? Wake-up and live, or... you'll find yourself like before... alone and lonely. This time I’m talking about the true loneliness, the one inside the chest. And I’m sure only the two of us really know about it and truly understand how it feels. That Abyss which you kept hidden from the world back then. In this life, you'll share with this family. So open up your heart to us, or... I'll do my best to break those walls one by one myself, even if you'll end up hating me for what I did for the rest of your life.”

Lily said that then left to enter the cave to play with Sun and Moon while Lin just kept staring at thin-air in a daze for a long while after she left.

“Ah!...”

Lin's mother found out that her beloved boy is silently crying for the first time in front of her eyes! panicking after seeing this new emotion overtaking her son she hugged him tightly to her chest and started to pat his back hoping that in doing so it would give him some comfort.

That simple action from his mother made Lin's tears fall faster on his cheeks like stream-water reaching the point of cascading-down from the edge of a waterfall.

Finally after half an hour of crying Lin calmed his agitating emotions and all the burdens he still carried from his previous life fell-off from his shoulders. Deep-down he was still endlessly worried and anxious about what happened after his death! even if they managed to creating more of the matter capable of saving humanity from the events of end-day that simply doesn't mean they survived.

Because nobody knows when will end-day come to happen.

That’s why Lin is always worried! what if? after he died all the universe followed after him. Because before they managed to make their so-called "ark of salvation" they got wiped-out by the disintegration shockwaves.

After Lily's harsh words Lin came to accept his helplessness in the matters of the past because he now got to live and take care of his family which is the reasonable and responsible thing to do.

Thinking of the past will only widen that "abyss" inside his chest which Lily mentioned and birth more demons in his brain to cloud his thoughts.

“Thanks mom, I'm alright now.”

Lin wiped the tears from his face in his sleeve then kissed his mother's cheek and left her embrace after assuring her that he’s no longer sad or confused.

When she saw the regular calm smile returning on her son’s face and his eyes regaining their clarity Lin's mother finally let-go of her needless worries and gave him a shower of kisses and one last squeezing hug before releasing him from her embrace.

Then the father arrived with drunk steps and he was carrying hungry Lao on top of his palm while his face had a panicking expression covering it whenever his son cried louder.

He wasn't used to this painful noise before from the previous twins because they always kept silent or laughed at that age! then they started making sounds which they used to understand each other's intentions.

'Is this one broken!' Lin’s father thought while handing his youngest child to his wife.

Lin smiled at his father's expressions and cleared his mother's embrace for his little brother to feed.

Then he went to find his sister Lily and found her combing the fur of twin-tiger cubs.

“Hey... parasite. Next time you want to say something, then come to your big brother directly. There's no need for the needless theatrics, in this family, the rules of grown-ups are defined backwards. Point is... next time, leave the audience behind, so that we grown-ups can speak freely.”

Lin hugged Sun's body to him and said rude words because he still felt like what Lily did was too much.

She pushed him to the emotional roller-coaster then finished with a bucket of ice-cold water to wake him up to the truth which he wasn’t yet ready to accept.

“Hehe... come at me bro, I'll let you spank, thrust, kiss, hug and do anything to make that anger go away.”

Lily winked at Lin provocatively then she pointed with her hands here and there on her body.

“Humph... so what if I come at you? these times have no clear lines and the circumstances might force me to take you someday! so don't you play these word games with me now Lily, all that knowledge in that head of yours is there because of my brilliance. Your whole body and soul were once mine, and still... are mine. If I take some pleasure from your flesh in the future, then, it's only returning home. Sweet home.”

Lin was squinting his eyes dangerously at Lily who kept her strong attitude and refused to budge or repent after he arrived.

“Well... well, well. Finally you're showing your true colors! aren't you ashamed for having eyes on your cute, adorable, and lovely little-sister.”

Lily seemed to enjoy having this conversation with Lin a bit too much.

“I said it before, so what? nobody will truly understand me on the deeper-level more than me, which equally means you. If I say otherwise, then I'll just be lying to myself, and you know how much I hate liars! right.”

Lin crossed his arms and rested his back on Sun's body when he spoke however his eyes were spitting fire whenever they met the careless eyes of his little twin-sister.

“Then... I'll give you the honor and promise you my first time, the ones after that though... I can't promise you, hehe.”

Lily felt proud of herself for playing with Lin's emotions that long and it felt good to have him playing in the palm of her hand.

“Oh! well, thank you. Then I guess my sweet little-sister will live a virgin, better get used to maidenhood Lily because your attitude just made it last a lifetime. Come Sun, let's go play.”

Lin wasn't happy for having this chat or talking this topic with Lily but she really pushed his buttons and he can’t be more frustrated with her today.

“Hehe, idiot. I told you earlier that you're a fool, now that the first part of my plan is complete. All I need to do is wait for the right time, then push your buttons... again.”

Lily muttered faintly to herself while she watched Lin leave the cave with Sun and a huge frown covering his face.

Now that his father returned from hunting with more success than usual. Lin's family got busy handling the food and storing it properly in the following two days.

Lin continued working with his father on the things their cave was lacking like finishing the kitchen or installing an air-circulation system in the ceiling of the cave and a fireplace. Finally it was opening another exit on the backside of their cave leading south.

After half a month Lin finally got to look towards the south direction for the first time without having his view blocked by mountains of rocks.

At the age of thirteen months young Lin saw the sea for the first time in this life at the far end of his sight and before it he saw the barren land stretching endlessly in-between where he stood and that blue somewhere far away.

But the difference between the blue from the sky and the blue from the sea was very prominent to Lin's expert eyes and he was sure that there at the far end of the picture his eyes are currently seeing there is water.

Not a small lake or a dwarf-sized sea! but a huge body of water and of that Lin was a hundred percent sure.

After finishing the backside gate to block the southern entrance which took three whole days Lin's father who got better at working in the forge took his new weapons and went for a new journey alone.

Lin didn't only make the cave-man work and drink liquor all day he also made a sturdy long-bow for the father and doubled the thickness and durability of the bowstring because the strong cave-man kept snapping the single-layered bowstring in training.

Even though his aim was completely terrible by all standards Lin's father had enough power to one-shot kill or mortally wound his prey with each arrow he fires.

Lin gave him two quivers worth of arrows and the good news were that the father's aim with long-range weapons especially javelins had improved to reach almost perfect accuracy on stationary nearby targets during this recent stay.

Of course the definition of "nearby targets" for the cave-man is about one-hundred and fifty meters away! he received another ninety percent hit-rate on moving targets at one-hundred meters range and that percentage increased to a staggering one-hundred percent hit-rate with the javelins on moving targets if they’re at seventy-five meters or closer.

Lin was amazed by these results because after more than half a month of training his father the cave-man can handle long-range hunting with his javelins or long-bow if his aim with it improved and can handle close-range fights with his sword and armor while giving him sufficient protection.

During the times he's idle Lin would train Sun on simple orders and routines because he wanted the tigers to join his father in hunting in the future to add another layer of protection to the cave-man.

But that won't happen unless they're capable of obeying orders and not causing trouble for the hunter since all the animals Lin saw so far were at least two sizes bigger than normal he feared the existence of larger or more dangerous species out there.

If the stupid tigers drew one such threatening creature towards Lin's father then he himself will be the main cause of his father's doom.

The mother was now enjoying her time being an idle housewife and this life was completely unlike anything she could've ever wildly imagined before giving birth to Lin and Lily.

She started to gradually speak broken words and understood new words every time she talked with her two kids. she would wake up in bliss because there’s comfort and safety then prepare breakfast following that she would clean her body and feed her babies. If she felt like it she would get a massage from her daughter or sometimes ask the girl for a new hairstyle! doing some light exercises and especially the thing called "yoga" was particularly to her liking and if she's in a good mood she'll bake something sweet for herself or see if she can learn a new recipe from her daughter.

Hearing Lily sing for her calmed her too and she secretly learned new positions and bed techniques from the little girl when Lin was away.

Lin would make her new things and tools to make her life more and more comfortable every time her man returned and she honestly felt like the happiest mother ever.

Every time she remembered that the mother would run for Lin and snatch him into her embrace and drown him in her overflowing love just to confirm to herself that this isn’t some dream! her worst nightmare became the idea of waking up from her sleep someday to find herself alone in this cave waiting for her man to return with some food in the cold and stinky cave from before.

From summer to Autumn the little boy didn't stop working hard whenever his father was back just to make the family’s life better! he even made something outside and called it "swimming pool" which the mother wonder a lot. Why would her smart boy dig such a big area just to fill it with water? he seemed really saddened that he wouldn't be using it until he turned two! that means sometime in the future! that means after she sleep and wakes up many times! the way her kids spoke confused her but somehow they always ended-up making sense later which convinced her to just trust in her kids. And she felt smarter daily because she no longer got confused by what new tool her son made for her to be used in the kitchen and sometimes she figured-out the correct ways to use some items on her own! when she talked with her daughter sometimes the words mentioned wouldn’t be hard for her to understand their meaning without need for the girl to explain.

The mother was very proud to have these kids because they even taught their stupid "pets" to relieve themselves outside the cave in the same spot and she no longer needs to clean after them! Not to mention how Lin started to teach his tiger how to behave and obey orders. Every day she felt better than the last one and she wasn't comfortable with the previous ways.

The father? He was feeling like a king of the world.

He goes out to conquer! whomever he finds cocky and daring enough to defy him out there? He clobbers the monster then brings it back and eats with his family. When he returns to his territory he finds his woman even more beautiful  and charming in comparison to the last time they met! she does strange moves on the comfortable bed his son made with him and these moves makes him experience feelings he never dreamed of coming close to. Not to mention the strange and new positions which he enjoys very much so! the liquor that makes his head go round and round in circles and the son who teaches him to make strange things. The daughter who hugs him and shaves his excess hair to give him strange haircuts! the food which tastes better every time he brings the things his son asks him to search for.

He even started to learn from his son how to do exercises and his power and strength got improved by a lot while his speed doubled! his focus reached another level which affected his control and aim with long-range weapons to become satisfactory. His adorable Lao grew bigger and the amount of food in the "storage room" is enough to sustain the seven cave-dwellers including the two growing animals for six months. Of course that was said by his son.

What about Lin? He was feeling truly bored with his days.

Even if he finished all his plans to offer a comfortable life for the family according to Lin’s estimations all his plans will be finished in at most another year.

After that there's nothing to do. He can start training to become stronger and superior to others his age but he's going to hit some kind of a limit sooner or later. Humans can only become super-humans after undergoing the genesis-operation and without that he wouldn't be able to give this world a thorough exploration! sighing he did the small plans while feeling like an aimless person walking in the dark in this life.

He could create some skin-suit for himself to use it in transportation but without the right materials and the support of advanced machinery then the best Lin can do is a primitive-model of those suits.

These models are easy to malfunction and the probability of them exploding during use could reach up to almost thirty percent!

“You're stuck with me bro.”

Lily jumped on Lin's back and said that to interrupt his thoughts which almost made Lin’s weak legs groan under the excess weight’s pressure.

“Won't you stop at anything?”

Lin tried to release himself from the little pervert’s chokehold but Lily held-on to him firmly from the back.

“You're mine, I'm yours, until the end of time... whoah! almost fell there, ehehe... tap or take a nap.”

Lily was speaking a load of crap when Moon joined in the fun and nudged the entangled twins with her head.

The tigers are six months old already and they’re no longer weak in the legs or taking any more of the shaky steps! Sun and Moon are already the size of a normal one year old tiger and their bodies are already capable of supporting the combined weight of both Lin and Lily since they were three months old.

Lily is the one who depends on Moon the most in this department because she’s always treating the white tigress like a transportation vehicle.

“Get-off of me Lily.”

Lin snapped at his little sister when he found it very unpleasant to be bent over under her weight while struggling to breath.

“I do get off looking at you, you know... every day, before I sleep.”

Lily snickered and untwined her arms from around Lin’s neck while saying that salty line then climbed on top of Moon's back and went towards the kitchen to eat some sweets.

Somehow Lin gradually started to get used to his sister's bothersome attitude after months of similar interactions and Lily became more daring with her words and actions much to his annoyance! thankfully she knew about him too well and Lily only did such things and engaged in these dangerous conversations in private and away from the eyes of his parents.

Because of his increasing free-time during the boring days of doing absolutely nothing other than being emotionally toyed with by Lily! Lin became increasingly curious about the world outside especially about their mysterious neighbor.

The poor guy. During one of Lin's tests he gave his father a mark to aim at as a target and it was a conspicuous high rock which had the red color at the northwestern direction. Somehow when his father took aim he got distracted in the moment before he let his arrow loose and it was Lin’s mother who caused such distraction. She bent over and scooped little Lao from the ground because he was about to eat one of the large ants crawling on the floor! the perky-butt got raised in a dangerous angle in her skin-tight mini-skirt made from dark and smooth leather and the father -in his daze- veered slightly off-target towards the west direction. The result of the fired arrow were devastating because it caused the destruction of their only neighbor’s cave when it caved-in and collapsed! when the man exited the cave after struggling to push away the falling rocks and prevent these huge stones from burying him alive he came directly towards Lin's family with a darkened face fuming with rage and kept making protesting sounds of "Ahh!... ooH" while swinging his arms in the air demanding explanation for the injustice which befell him.

Lin's father ended-up beating the neighbor without a single shred of hesitation and pinning him underneath his feet before checking if Lin was okay first! he even took a pose in front of Lin while standing on top of the vanquished neighbor and appeared to be saying : 'see! Your papa is mighty.'

Lin stopped his father from humiliating the beaten man anymore and compensated their only neighbor with some clothes and food. Finally the man snorted and left with his tail between his legs but he accepted the gifts which made Lin feel like it is a good start. When Lin decided to make his father bring the neighbor to live nearby them so that they can take care of each other in the future he found out that their only neighbor had abandoned his cave and left and from where his father pointed then the man went to live four kilometers away from them in the northwest direction.

He choose a tall mountain seven kilometers high to be the location of his new home and Lin decided to leave their neighbor be in peace for the time being. Maybe when he grows up then he'll pay the man a visit in-person but he made sure to give his father some extra food whenever he left to hunt with clear instructions to leave it at their neighbor’s place.

Soon it was the first signs of Lin's second winter again but this time the family was no longer afraid of the cold weather and falling snow or harsh winds.

Their food supply is more than sufficient. Their accommodations are top-class in these dark-ages and now all that's left to do is to teach these parents of his how to talk and start behaving like humans.

At the age of nineteen months Lin and Lily closed the doors of their cave to keep the warmth within their cave and their following days were mostly filled with constant lectures given to the parents.

The one who felt most irritated with this new routine was the father because Lin forbade him from drinking liquor unless he did good in his pronunciation or learning classes.

The mother was a quick-learner and after only one month of intensive lessons she's no longer confused when she listen to the twins speak. Some words she feels like she understands their meaning but they're related to some topics of knowledge or science and that’s why they would be hard-to-swallow without further explanations from either of her children first but she persevered and gave it the necessary effort to be better.

All in all by the time spring scattered winter's frost both of the parents were capable of speaking their intentions clarity to their children without throwing any confusing words in the mix. Saying something understandable like : I'm hungry and feel like eating some roasted meat or my stomach hurts because I ate too much! became within the two adult’s abilities and Lin and Lily could finally say that their work during the past few months was a success.

Words which can be understood in different ways started to vanish from the family’s conversations gradually and if it wasn't for Lin and Lily's perfect understanding and capability to translate body-language then their day-to-day interactions with their parents would've been a complete confusing mess of misunderstandings.

“Honey, do you want me to bring you back anything from outside?”

Lin's father was fastening his armor straps and asked his wife if she wants anything specific for him to bring back from his hunting journey.

“Some veggies and fruits would be lovely, keep your eyes open for more spices, oh! Almost forgot there... see if you can catch some birds alive this time. Most of these eggs you brought last time didn't hatch, and Lily said that we need to have a variety of species in our poultry farm project before we start cultivating bird-meat. Have a safe trip hubby, I'll miss you terribly in these lonely, long, and cold nights.”

Lily made sure to turn her mother into a version of the most tempting and captivating housewife and Lin's father eyes instantly glowed with lust when he heard these soft and seductive words from her! He was only able to escape the charm of his wife and stifle his fires of horniness after biting the tip of his tongue slightly. Hurrying to carry his sword, bow, spear, arrow quivers, dozen javelins, and spear the man of the cave left under the giggling laughter of both his daughter and the wife.

Surprisingly the parents didn't choose names for themselves after becoming aware of their previous ignorance to the ways of communication through speech and they refused to give Lin any clear reason why would they prefer to remain nameless and kept avoiding the topic whenever he brought it up! Lin didn't want to be pushy and left his parents the freedom of choice and choose to give them time while thinking : 'maybe they don't want to hurry themselves, maybe they didn't find the suitable names yet, or... they have their own reasons and don't want to disclose them to him.'

Unbeknownst to Lin the reasons for this particular matter with his parents will be revealed to him many years later and the parents will keep being nameless for many years to come.

But that's a story to be told in the future.

Now he's almost two years old and Lily is having fun eating various kinds of food instead of relying only on breastfeeding despite her love for boobs! but she’s distracted enough from her mother’s chest because of the existence of sugary drinks and candy.

Little Lao is already trying to stand like his siblings and is still very much the most adorable and cutest person in the cave. Lin often takes him for short rides on top of Sun's back just to enjoy his tinkering laughter and his little brother became Lin’s source of entertainment whenever he feels bored with his days.

Other than that Lin would go for a swim in the pool with Sun or try to train the tiger and teach him new tricks and moves.

If Lin happened to find that his mother is bored too then he'll try to teach her something trivial and interesting from the knowledge he gathered in his previous life because that borderless ocean of knowledge in his brain was left to collect dust in this life so far! Lin honestly felt that he has no need for that excessive amount of information because if he's going to be reborn in such backward times then why's the need for his previous memories and knowledge to be wrapped-up and stuffed together with his soul.

But if it wasn't for that knowledge then Lin would've most likely died from the cold in his first winter and his helpless parents would've scratched their heads for a while after his breathing stilled then threw his cold baby-body outside the cave alongside his accumulated pile of shit when the stink became unbearable! then Lin just stopped overthinking the topic all-together or worrying about it needlessly and gradually decided that he better change his perspective about this whole situation until he finds a reasonable reason to dig-out the past life. Because Lin did what he can do and gave away his life without hesitation for a chance of survival to his man-kind. Whether it was a success or not has got nothing to do with Lin and his conscience is clear if it was a failure.

Lin told his father to search for metal ores in his trips and to try and bring some samples back with him. Next step in his plans is generating electricity for the family if metal is recovered from the father's exploratory trips. They can start with hydropower then turn to solar energy later. What about generating energy from ignition? Lin never liked the pollution resulting from it and he isn't that desperate for energy yet.

Their home could be relocated to the south because ever since Lin noticed one short mountain with a wide surface of about one kilometer at the summit he couldn’t stop sketching a blueprint in his brain for a better home instead.

That mountain is three kilometers away to the south from their cave and it’s five kilometers high and whenever Lin looked at it he kept having the same idea : 'the view from up there must be something really good.'

Looking south you'll get a better look at the southern waters and Lin had nothing else to do anyway. So why not?

When his father returned Lin would ride Sun and go with him to that small mountain to work on making a newer, bigger, better, and higher home for his family.

During the three months of spring Lin finished four escape-tunnels leading towards each of the four main directions. Each tunnel led from all the way from mountain-top and ended three kilometers away from the base of the mountain. These tunnels has reinforced gates on both ends, reinforced walls, reinforced ceiling and floor, and reached the total length of eight kilometers at least. Sturdy spiraling-stairs installed to lead all the way up the mountain and a long and slim pole in the middle for a quick descent down from up the mountain when needed! Lin added melted bones to the concrete formula and its resistance reached a whole another level of strength.

But these tunnels aren't the main way to enter their new home of course. Lin just made them to be used in case of an emergency because during the second month of spring he saw some kind of avian roaming the sky above the east mountain-chain from their cave! Lin estimated that this avian is flying at least fifteen kilometers away from where he stood and after doing a simple mathematic calculation he was sure that this bird has a wing-span of no less than ninety meters or so if not bigger.

And that is the reason Lin made the tunnels first before working on building their new home! to escape with his father if such a thing targeted them while they’re working and only after the tunnels were completed did he start to work on clearing the mountain-side southwards from the summit down towards the southern foot of the mountain.

The plan was for their new home main-entrance to be from the south with large and wide steps leading up and statues of his parents and family as well as Sun-Moon pearls decorating both ends of each step.

Gardens and trimmed trees to the left and right beyond the statues on the steps for the guests to enjoy the scenery when they climb the mountain with murals carved on the steps and chandeliers hanging from archways spreading lights to show the way and decorated with beautiful colors.

Finally up the mountain would be the palace of Lin’s family surrounded by gardens, pavilions, artificial streams, bridges, and lots of ideas which Lin is eager to present on the empty summit.

But it’s his and Lily’s second birthday party today! he's officially graduated from breastfeeding period and Lily is feeling downhearted about the idea.

She kept pinching Lao's cheek gently because from now on these two perfect breasts of their mother which would ripple on the slightest breeze or motion are exclusively his from now on.

“Stop it Lily, Lao will cry if you keep bullying him, and mom wouldn’t hesitate to punish you or me.”

Lin removed Lily's fingers from his idiotic brother's face when he spoke because Lao kept giggling at what he thought to be some kind of a game which his sister is trying to play with him! they already made another birthday party for Lao a few days earlier to celebrate their younger brother’s first birthday and Lily alone almost ate half the cake just to prove to Lin that point : 'he can't tell her not to eat sweets anymore!'

Lily knows how to take well care of herself and Lin just did his best to hold her back until the very first two critical years of her life safely passed without any major complications and from now on her diet has nothing to do with him anymore.

“Look at how fancy he looks in these clothes I made for him, my birthday gift for Lao is the best. See how he neglected your little "puzzle" after two hours, humph... just the mere idea of how he will be sucking these nipples all by himself from now on is making me a bit angry at him! tsk... I need to stretch these cheeks a little, for him to gather loads and loads inside that cute mouth of his, then as his big-sister it’s my job to do it.”

Lily hooked her left arm around Lin's right arm and started to arrogantly speak while teasing Lao some more then she held Lao's hand and walked outside the cave together.

“You're a girl, please start acting like it. Someday, cough!...  you'll have your own pair. So, why rush?”

Lin was avoiding eye-contact with Lily when he mentioned that sensitive topic but unlike his –always hungry for breasts- sister he was feeling very happy to finally reach that age.

From now on he can exercise more in the pool under the strict condition which is that he doesn't overdo it like never! when he’s at the age of four can Lin start practicing something like gymnastics for example.

Only when he reach the age of six years old can Lin intensify his physical training and test his limits! that way when he grows-up and go out to explore the world by himself at least he wouldn't be bullied.

His father’s abilities proved to Lin that his strength can increase without limits because the "ex-caveman" is still growing stronger and faster every day! the physical tests Lin gave to his father has resulted in higher and higher records of the man's achievements and if Lin can do the same then he wouldn't fear any regular and mortal human trying to harm him. At least he wouldn’t feel helpless against a crowd of angry mortals and Lin would be assured of his ability to escape.

If it is gigantic creatures like the one in the sky trying to harm him then Lin would just steer-clear from them and use his superior intellect to avoid confrontation to the best of his abilities.

“You’re absolutely right! how about it? don’t you want to help me massage my "pair" when they start to swell-”

Lily squinted her eyes and smiled a very cunning smile when she heard Lin willingly mention such matter which is normally a taboo subject for him. Trying to drag her brother deeper into the muddy and sensitive topic was prevented by their parents at the right time in Lin’s opinion and the worst time in hers.

“Happy birthday to you...” is the song the couple sang for their twins. Authentic smiles from the heart were all over their faces and someone like Lily couldn’t find it within her to be mad at her parents no more for interrupting her conversation with her big-brother just when it began to reach her favorite part.
