"Speed run?" [Other]

"Yup, basically we will skip all the other 10 floors and went straight into the final boss!" [Ash]

"Well, the floor in this dungeon is rather "thin" but, is it really doable?" [Karon]

"Oh it is, just listen" [Ash]

The challenge dungeon floors are rather "thin", that is if you're comparing it to the normal dungeon in Achalasia. What the two of us meant as thin is simply we can measure it from one floor to the other, unlike that of the normal dungeon (which honestly make the ancient tunnel the more mysterious) 

Right now, there's four, no five of us that can use earth mana (me, Lara and Nara after I give them my mana, Karon and Bobunny), so it is doable. But why stop there, Zerolith here can use his dark magic to erode the ground beneath us, making our job easier, and since this is part of the ice dungeon, Savel Ice magic (thanks to the Holy beast of water, Reshir blessing) will also be useful. Singa can help by teleporting a large rock or any accumulated dirt along the way to somewhere else, and even act to teleport us all to safety shall any danger befall us. 

(And let us not forget I can also help Zerolith, Singa and Savel doing their job, and so does Lara and Nara by extension) [Ash]

It's possible, and it safe us more time (maybe not save our mana, but hey, there's a first time for everything)

"Alright, Let us do it!" [Zerolith]

"I can't wait to brag to them!" [Singa]

"They will really be surprised" [Savel]

""Let's go!!"" [Lara, Nara]

"You betcha!" [Ash]

~Chuckling~

Putting my right hand into the ground, we start to dig, and

"It's regenerate back!" [Savel]

"How mysterious" [Karon]

"It is, but..." [Ash]

There are several mana components and, I got this feeling that I can actually absorb it and use it to my advantage. Wait, that sound like what a homunculus will do, which mean

"Lara, Nara, can you try to absorb the mana that disturbs our work? I'll help as well" [Ash]

~Nod~

And we begin it once more, and

"You guys are doing great!" [Zerolith]

"Especially Lara and Nara!" [Singa]

"Right, let us go everyone!" [Karon]

"Right!" [Other]

So our plan works! That's good, but, once again, I can't help but to wonder, why is the challenge dungeon floor has this property while the usual dungeon didn't? What or who exactly makes the challenge dungeon? And once again, I can't help but to relate what we are doing to that of the Traveler King. What we are doing is basically a mini project mimicking that of the ancient tunnel. I'm sure the answer is no, but is this how the ancient tunnel was built? What method did the Traveler King used back then, and does he work all alone back then. Did he receive any blessings from earth Holy Beast to ease his job, and if so, does the earth blessing any differ from that of the Tyrant Ant, Drant. So many questions, and yet I can't even answer one of it

~Chuckling happily~

"Man, you're still full of energy aren't you Bobunny" [Zerolith]

"He is made out of an S rank magic core after all" [Ash]

""..."" [Lara, Nara]

"Need more rest..." [Savel]

(Haha, his tattoo mark started to disappearing, he must have use a lot of mana) [Ash]

"Agree, maybe we can fight the final boss in an hour or so?" [Singa]

"I'll scan the monster from here first, so you guys get some rest" [Ash]

~Nod~

Using my scan magic, I can sense the presence of a ghost monster, a Yuki-ona. This could spell trouble, and her strength is a limbo between that of an A to S rank monster. I couldn't possibly ask them to back me up, but at the same time, I wanted them to experience fighting against Yuki-ona. This will be dangerous, I should let them stay here, but then again, shall I leave them, they might get attack by other monsters. 

"Bobunny, can you shield them while I am fighting the Yuki-ona?" [Ash]

~Chuckling and nodding~

"Thank you, that's your primary job in this battle!" [Ash]

"And how about us?" [Zerolith]

"You guys should just concentrate on giving fire support. Under no circumstances should you be separated from Bobunny! Got it?" [Ash]

"Yes!" [Other]

After resting till our fatigue all gone (and chugging down some mana potion, which at this point I should grind more of it from the loot drop by the zombie from the zombie spawning block), we enter the final boss room, and is immediately greeted with an avalanche of snow dropped towards us

~Hissing~

A horizontal wall is quickly made by Bobunny, holding the snow from crushing us. Bobunny then quickly made a shield out of steel magic, expanding all its mana to make a titanium shield that barely cover my siblings from all directions. It can manipulate the shield as to let my siblings launch an attack. As for me, I quickly drew my scythe and as usual, imbued it with multiple mana properties, especially fire, light and dark as Yuki-ona is weak to it

(Yuki-ona is like a mage, so it should be weak in close combat) [Ash]

But, a high level mages will surely have their weaknesses covered, and true enough, Yuki-ona started to summon ice skeleton. They're weak but holy hell, just how many can she produce! 

"Take this!" [Savel]

Savel quickly uses his ice magic and make multiple Ice spikes. He maneuvers it nicely, not hitting me even once. 

"Singa, we will take care of the ice skeleton, so made a teleportation here and one more above the ceiling, that way we can fire more freely!" [Karon]

"Sound good" [Zerolith]

"But what if we hit Brother Ash?" [Singa]

""Don't worry!! Won't!!"" [Lara, Nara]

"He's agile, there's no way he would let us hit him" [Zerolith]

"If you said so..." [Singa]

I heard that... guess I should live up to their expectations... but Zerolith, how do you expect me to dodge all this incoming dark arrow of yours! Forget about arrow, at this point, it like a machine gun barrage! And I'm more surprises as how  Singa can cope with all of this! Well, I can't detect Lara and Nara mana, so they must have support Singa teleportation spell as well

~Freeze~

"Tchh..." [Ash]

Just a single touch to my shoulder, and a frost quickly envelop it, limiting my right shoulder movement. 

"Haaa!" [Ash]

I quickly cover my whole body with fire mana as to combat it, but the Yuki-ona keep on sending her mana into it. What an amazing ability, all she need is a touch and once she touches you, it's all over as she will keep on sending her mana to freeze you. How terrifying, but

"You should do better than this!" [Ash]

"!" [Yuki-ona]

Once again, I gather all my fire mana, and this time, I make a huge fire ball and quickly throw it to her. Of course she evade it easily but 

"Fire ball disperse!" [Ash]

The huge fire ball become multiple smaller fire ball and few of it manage to hit her, and even one setting her long black hair and clothes on fire! 

"Chance!" [Ash]

Even my siblings realize it. They quickly ignore the never ending ice skeletons and quickly focus fire on the burning Yuki-ona

"Darkness whips!" [Zerolith]

"Glass spikes! Cover the whip!" [Karon]

"I'll add mirage spikes as well!" [Savel]

Zerolith spells hit her head on! Now entangle, she unfortunately quickly destroy the whips

(Well, unfortunate if you're late to react) [Ash]

As for me, this chance created by them isn't going to be wasted, as with my acceleration magic, I quickly dash toward her and slice her. She tried to retaliate by making an ice sword to stab my heart (literally of course), but alas, Bobunny quickly shielded me from it by making a small armour around my chest 

"You're finish!" [Ash]

I added inferno magic to my scythe as a final touch and

"We won!" [Zerolith]

"The ice skeletons are all gone" [Singa]

"That was tiring" [Savel]

"Agree" [Karon]

""Treasure chest!!"" [Lara, Nara]

"Yup" [Ash]

After storing the Yuki-ona magic core inside of my item box, we quickly go and take a look inside the chest but

"Empty..." [Karon]

"ARE YOU KIDDING ME!" [Zerolith]

"All our hard work..." [Singa]

"This is unfair!" [Savel]

""Nothing..."" [Lara, Nara]

Not quite... Treasure chest supposed to disappear if it's empty, so

(Better scan it) [Ash]

And my scan magic reveal something unbelievable

"!" [Ash]

"What's wrong?" [Zerolith]

"Nothing... well, better store this treasure chest inside my item box" [Ash]

"But it's useless..." [Zerolith]

"Who knows, at least we can store something inside" [Ash]

"What a let down" [Zerolith]

Haha, ohh you won't say that if you know what it is, plus, this will be the perfect birthday present for her (or should I keep it for myself?). Nah...

After I stored it inside, a tremor started and all of us are getting dragged out. The challenge dungeon is closing! 

"Stay close!" [Ash]

"Right!' [Other]

Well, nothing bad will happen. We are just getting transported out, but just to be safe, I covered them with my own mana as to increase their defense
