Liza went limp and lay down after hearing Satou's words. Then Satou turned and looked at the former C rank adventurer.

"Are you willing to try injecting mana into this magic gun?" Satou asked and handed the magic item to the former adventurer.

The former adventurer was a little scared. However, other people were curious about the magic gun.

"Let me try, I'm a magician so I have more mana." Said a female former C rank adventurer.

Satou was silent for a while and then handed the magic gun to her and said. "Five seconds, don't charge too much longer than that. You could run out of mana and pass out if that happened." The former adventure mage nodded his head.

After that, she took the magic gun from Satou's hand and started charging mana into the magic gun. The crystal stone on the magic gun then glowed.

"One" Satou started counting the time.

"Two" The former adventurer started to sweat.

"Th…" The former adventurer let go of the magic gun from his hand, then she fell and fainted instantly.

"Three seconds and she's out of mana? It can only be used 10 shots." Satou took the magic gun.

Satou then filled the magic gun with his own mana.

"No way. I know Rin. She can fight using mana for a whole day and she won't lack mana. But why did she faint in just 3 seconds?" The former B rank adventurer said.

"Ohh, her name is Rin. She has quite a lot of mana." Satou praised Rin who was unconscious.

The crystal on the magic gun glowed for more than 5 minutes until Satou stopped charging his mana and nodded his head. Then Satou looked at Rin who had fainted and was being cared for by his other comrades.

"Did she need long time to wake up?" Satou asked one of Rin's comrades.

"Because she's ran out of mana, and she has quite a lot of mana, so the time it takes will also be a little longer." Rin's comrades looked a little confused.

"Use this, the sooner she wakes up, the sooner we can get down and finish our exploration." Satou said while passing a mana potion to Rin's companion.

Rin's comrades just gaped and accepted the potion given by Satou. "Are you sure? It's expensive, isn't it?"

Satou just tilted his head. "Expensive? I have plenty, enough for all the citizens of the entire town to consume it every day for over a month." Satou said with a straight face.

Everyone who heard Satou's words could only stare in disbelief at what they were hearing.

"Master, how much do you have?" Arisa ventured to ask.

"I don't know, I stopped counting after over 1 million bottles. Ohh, I also have the same amount of health potions." Satou answered Arisa's question.

All the former adventurers turned pale at Satou's words.

"Hahahahaha... I was an adventurer for many years and finally retired after becoming a B rank. And finally decided to become a slave because I didn't want my life to stop after I retired. But here I found someone who has more than 1 million bottles of potion with the price of 5 gold coins per bottle. Hahahaha.... how much is 5 million gold coins..."

Everyone who listened to the former adventurer's words could only nod.

"Master, where did you get that many potions from?" Arisa asked because she was curious.

"That many potions couldn't possibly be made by humans." Arisa add another word.

"I got it from Akon Kagura. She gave me this bag and its contents when I refused to be the hero and his representative." Satou answered while teaching Lulu to shoot on target.

"Satou, why did you refuse to become a hero? You can do anything if you become a hero, you can even marry a princess, right?" Satou just tilted his head.

"Princess? Royalties will only get me into trouble. With politics that don't really matter." Satou said with a hint of sarcasm.

Captain Kigouri couldn't help but smile at Satou's words. For captain Kigouri who was more or less knowledgeable about the political situation of the nobles, Satou's words were indeed true.

Everyone was silent after that. Seeing the atmosphere that became a little heavy. Captain Kigouri decided to tell everyone to rest.

Finally, while waiting for Rin to come to her senses, everyone rested except for Lulu who was learning to shoot with Satou.

"Master, sorry. I still can't hit the monster." Lulu lowered her head.

"No problem, you can practice again later. For the time being, let Arisa kill the monster." Hearing Satou's words, Lulu calmed down a bit. Arisa who also heard it became happy.

"Master, can I kill the monster now?" Asked Arisa with a big smile on her face.

"Go ahead. You can also use the monster to train too."

Arisa shoots her magic right at the spider monster's head.

"Master, it seems I don't need to train." Arisa said while puffing out her chest.

After resting for a few minutes, Rin woke up from his stupor.

"Rin, are you okay?" asked her partner. "Not really." Rin answered while holding her head.

"Are you still feeling dizzy?" Her partner asked again.

"Of course. My mana runs out in an instant. Of course I have a headache. This is the first time I've ever felt such a thing called mana depletion. I don't want to feel like this again."

"Hahahaha. I thought you still want to give it another try?" Satou said a little sarcastically to Rin.

"Only a madman would want to feel his mana run out. And only a person with a mountain of mana can fill that magic gun. That's impossible for me, so don't ask." Rin was a little annoyed at Satou's sarcasm.

"Hahahaha. You can run out of mana because you can't control the mana you send when you inject it to the magic gun. If you can manage it, you won't run out of mana." Satou slightly explained to Rin.

"Manage the mana I send out? What do you mean?" Rin and the others tilted their heads in confusion.

"Master, we can't control how much mana we release freely. Every magic has a certain amount of mana to be use so that the magic can active. Even charging the mana into the magic item is already set when the magic item is made." Arisa explains what the others agree with by nodding their heads.

"What Arisa said is true, Satou." Zena also confirmed Arisa's words.

Satou who heard Arisa's explanation couldn't help but sigh. Then Satou turned and faced the labyrinth wall.

"##### fire ball"

A fireball appeared in Satou's hand and shot towards the labyrinth wall and exploded after hitting the wall. Everyone was confused about what Satou was doing. Then Satou repeated what he was doing.

"##### fire ball"

However, the fire that comes out is small and travels at a slower speed. The explosion that occurred was also smaller than the previous one.

Then Satou faced Arisa and said." If what you said earlier is true. Why with the same chant the magic that comes out different?" Everyone is confused, especially Arisa, Zena, Rin and those who can use magic.

"Masters?" Arisa is confused and shake her head.

"Magic can be used when we chant right?" Arisa and the others nodded.

"Actually it's all wrong practice. When we chant, we actually subconsciously supply mana to the place where we're going to realest the magic. If we use the staff we supply it into the staff, if it's by hand, we supply it into our palms. Inside the chant there is a word where we have to supply how much mana to activate the magic. However, that word can be discarded when we can control our mana supply at will. It is also one of the techniques to cut off the chant we have to say. Like this."

Satou then thrust his hand towards the wall.

"### fire ball"

A normal fireball shot out of his hand and shot towards the wall. Everyone was stunned to see what Satou was doing.

"But people who can shorten their chant usually don't realize this and they supply mana according to what the chant usually demands." Everyone is still a little confused.

Seeing that, Satou again thrust his hand towards the wall. Satou was silent for a while. Then he said a chant.

"# fire ball"

The fireball that comes out is small. However, the fireball flew at a very fast speed and the explosion that occurred was very large.

"In addition to reducing. We can also add mana to the magic we will use. Besides, how dense the mana we prepare also affects the magic power we use, especially magic attack." Everyone was stunned by Satou's words.

"But, how come I've never seen anyone else use a technique like yours?" A former adventurer asked.

"Because this technique is difficult to learn. Instead of learning to shorten your chanting, it's better to learn to chant while fighting. It's more beneficial, although in the end we still have to be able to regulate our mana usage."

"Master, then how do you practice managing mana usage?" Arisa asks a little curiously.

Satou fell silent after hearing Arisa's question.

'Host, in the inventory there is a magic item that can be used to practice managing mana usage.' Dea told Satou.

'Sigh, there are too many items in the inventory. I can't remember everything inside.'

'It's in the miscellaneous tab. It's shaped like a baton.'

'Oh, that thing. At that time I thought it was a weapon but it wasn't. And i just found out that its function is to practice controlling mana?'

'Although most people only use this for children's toys. Because children are using it, and how much mana do children have? In the end, not many people know about the other functions of this magic item.'

'Thank you, partner.'

After conversing with Dea, Satou took out the magic item. Zena was surprised by the magic item Satou took out and immediately took it from Satou's hand.

"Isn't this the magic item that i usually play with when I'm little? If we pour mana into it, it will light up." Zena said while pouring mana into the magic item in her hand, and the magic item glowed blue.

"The more mana flows, the brighter this thing glows." Zena plays with the magic item by injecting mana into it.

However, the mana that Zena flowed was not the same, so the magic item flickered.

"Zena, can you channel the same amount of mana?" Satou asked Zena.

Zena just tilted her head. Satou then looked at the others and only got a shake of their head in response. Satou could only sigh seeing it all.

Then Satou took the magic item from Zena's hand and poured mana into it. The magic item started to glow and finally calmed down with a light that didn't flicker at all.

"How!!! Why is the light not blinking at all?!" The former B rank adventurer screamed in disbelief at what he saw.

"We'd better continue exploring this labyrinth first. We still have plenty of time after this, don't we?"

Everyone then realized that they were in a labyrinth.

"Sorry, because this whole thing came as a shock to me, I forgot that we're in a maze right now." The former B rank adventurer scratched the back of his head. Satou just nodded in respond.

After that he called Liza. "Liza, have you taken the core?"

Liza who heard her name being called immediately turned around and faced Satou.

"Yes, master." Liza walked over to Satou and handed the core of the spider monster to Satou.

"Good, now let's go deeper."

Then Liza walked away from the others, Pochi and Tama followed not far. After that Arisa and Lulu are followed by Satou. And finally the others followed not far.

After leaving the room with the spider monster, their journey was not as easy as before.

They met a lot of monsters. A group of monsters of mice, caterpillars, slimes, skeletons, and insects which are usually three to five monsters per group. Especially with the traps that can be considered deadly. Poison, pitfalls, chunks of rock falling from above, dozens of poisoned arrows, sharp thorns coming out of the floor, monster houses, even mimics also appeared.

"Why do I feel that this labyrinth has become a little more difficult than before?" Satou said with a difficult face.

"Satou, wasn't it this difficult before?" Zena asked.

"No, monsters only appear once in awhile and usually alone or just two monster . And there aren't that many traps either."

Everyone was surprised to hear Satou's explanation.

"So what are we going to do. Continue in or give up and get out?" The former B rank adventurer asked.

"I'm still hoping to get to the deepest room. I want to see if this labyrinth has a boss? Because when this labyrinth first appeared, the boss was an eyeball demon. But I killed it and the greater hell demon was killed by a weird annoying hero who just happened to be passing by. And with the labyrinth's conditions becoming more difficult, there's no way this labyrinth doesn't have a boss, right?"

Everyone started to realize what Satou wanted and nodded their heads.

"But we have to be more careful, I know that you and your group are strong. But anything can happen in the labyrinth." Said the former B rank adventurer. Everyone agreed with his words.

After a little chat, they continued their exploration into the labyrinth. The monsters that appeared also became more and more ferocious. However the traps were reduced which made them a bit calmer. With more monsters appearing. Everyone became involved with the fight. But with Satou's direction, they were able to fight the monsters without any casualties.

With Satou's direction, they continued on their way deeper with more caution. Until finally they found a large iron door blocking their way.

"Whatever it is, it looks like there's a boss in there." Rin was the first to say something after seeing the iron door.

"Yeah, whatever it looks like. That's definitely the entrance to face the boss." Another adventurer answered.

"Since we're here. Let's just rest first. We need to recharge our mana. And I'm sure you guys are tired too, besides some of you must have leveled up too. So we'll rest until I say we're ready to go inside." Satou said suggesting something to everyone.

Captain Kigouri nodded. "It's true what Satou said, we should rest first. We will take turns guarding."

Captain Kigouri then gathered all the captains and adventurers to discuss the division to guard while they rested. But while they were discussing it all, a barrier appeared and enveloped them all. Captain Kigouri and the others saw Satou and his group sticking something into the ground.

"Satou, is that a magic item that acts as a monster repellent?" Captain Kigouri asked to be sure.

"Yeah, I often spend the night in the woods when I travel, so this thing is very important to me. Can any of you cook? I have plenty of groceries." Satou answered and asked with a straight face while driving a 4 meter long iron pole into the ground.

After that, the tip of the pole lit up and lit up the whole room.

"Monster repellent, lamp, don't tell me you also have a stove magic item?" Captain Kigouri asked slightly annoyed.

"I have. It's easy cooking with magic items." With a straight face Satou answered while taking out a stove magic item and groceries.

Satou then asked Liza to cut the meat and vegetables which Arisa and Lulu than helped her.

Captain Kigouri and the others couldn't help but stare at Satou and his group who were not tense at all.

"With the monster repellent, it looks like we don't need to be on guard." Captain Kigouri said slightly annoyed.

"And which of you can cook? Help Satou and his group. Cooking for this many people isn't easy." Captain Kigouri continued.

Everyone nodded their heads and those who could cook walked over to Satou intending to help. Finally with a bit of a heavy heart for not doing anything. Captain Kigouri and the others rested while waiting for the food to be ready.

Satou finally handed over the task of cooking to the soldiers who usually prepared food for the army. Satou finally sat down and took out paper, pen and ink from the inventory. Zena who saw Satou became curious.

"Satou, what are you doing?" Zena asked.

"I'm trying to make a map of this labyrinth. Information like this is very important for future exploration. Besides, information about monsters and traps is equally important. That's why I planned to write down all that information." Satou answered while focusing on drawing a map from the first floor to the front of the iron door.

"Satou, do you remember everything we went through?" Zena asked slightly amazed.

Satou just nodded in response.

"Wooohhh" Those who noticed Satou became amazed by Satou and started to surround him.

"Unbelievable, he even remembers the trap position too."

"Look, that's a magic trap that shoots poisoned arrows, and that one's a pitfall. There's another trap too. How good is his memory that he can remember such details?" The soldiers and adventurers started talking about Satou who was drawing the map.

The crowd only dispersed when the food was ready. And everyone started eating. Liza intends to give food to Satou, but Arisa stops her because Zena also intends to do the same. Understanding what Arisa meant, Liza stopped her intentions and ate with Pochi and Tama.

"We'll get our own time. For now, let Zena serve the master. But tonight, we will serve the master. Hehehehe" Arisa laughs a little slyly.

After they finished eating, all of them went to sleep because of the fatigue they finally felt. Satou was still creating the map and writing all the information about the monsters and traps that were in the labyrinth. Zena who actually wanted to accompany Satou finally fell asleep as well. Pochi and Tama have also fallen asleep from being full.

Seeing everyone asleep, Arisa approaches Satou and hugs him from behind.

"Arisa, don't mess around here." Satou slightly warns Arisa.

"Hehehe, just a little." Arisa hugs satou tightly from behind.

Liza and Lulu who are still awake are also getting closer.

"You guys better sleep, especially Arisa and Lulu, you guys have leveled up, so you guys need to sleep." Satou suggested.

However, the three of them didn't answer and just hugged Satou tighter. Arisa hugs Satou's back, Lulu and Liza hug from the side.

"huhf, since when did the three of you become spoiled like this?" Satou could only sigh.

Arisa just giggled hearing Satou's words.

"Okay, I'll give the three off you a goodnight kiss, but you'll have to sleep after that."

After that, Satou kissed the three of them one by one, and the three fell asleep after receiving a kiss from Satou.

After a few hours, Satou finally finished drawing the labyrinth map and writing down all the information about the monsters and traps. Without his knowing, someone hugged him from behind. Satou turned his head to see who was hugging him. Satou was surprised, but also relieved to find out who was hugging him.

"Dea, why did you come out?" Dea pouted slightly at Satou's question.

"Did you forget? You promised to give me whatever I wanted if I killed the hell demon from yesterday accident." Satou only remembered after hearing Dea's words.

"Sorry I forgot." Satou bowed down and apologized to Dea.

Dea just turn her head. "Hmmm"

"Don't be like that. Now what do you want?"

"I'm coming in too. I want to introduce myself to Arisa and Lulu too." Satou just tilted his head in confusion.

"Are you sure?" Satou ask.

Dee nodded. "Besides, there will be interesting things inside." She giggled.

"Do you know what's in there?"

"Not really, but I can more or less guess what's going to happen in there when you guys come in."

"huhf, I better just enjoy what happens next." After talking, Dea changed into a white-haired hero and sat in front of Satou while eating a lollipop.

"Why do you have to eat lollipop?" Satou asked.

"To make Arisa immediately think that I'm from Earth."

"Why don't you just wear a NY hat. Or maybe a famous soccer club shirt. Or wear a t-shirt that says "I Love Japan" she'll definitely think you're a weibu" Satou said while preparing the food.

Plaq!!!

Dea hit Satou's head with a large paper fan.

Satou just stroked his head and then he took a bell from the inventory and rang the bell.

Before long, Arisa and the others wake up one by one. Followed by Zena and the other captains. Then the adventurers also woke up after that.

"Ahhh, master. Is it time for us to enter?" Liza asked while rubbing her eyes.

Pochi and Tama staggered closer to Satou, then opened their mouths "Ahhh" Satou then put honey buns into their mouths which made them open their eyes. Not long after, everyone woke up.

"Before we go into the room where there is a possible boss, you guys eat first. I've prepared everything." Satou said while pointing to a large pot.

Everyone was then queuing for food. Unlike the others, Zena and Captain Kigouri walked over to Satou and sat beside him.

"Hero-sama, what wind brought someone like you here?" Captain Kigouri greeted the white-haired man sitting in front of Satou which made everyone there focus on the man.
