-What is this place?

Tesuo looked around the place, it was a large room decorated splendidly, a bit of an ancient style as if it was a place from the medieval era, on the ground was a giant magic circle and everyone was inside it, in the distance were more than 30 people standing at each different pillar and it seemed like the people in this room had summoned them.

Tesuo looked up and saw a standing area decorated with gold plating with 3 people standing.

-Welcome to my castle, people from another world.

The person in the middle shouted and it seemed like he was the master of this place or perhaps an emperor.

-I know everyone is wondering why they were summoned to this place.

He turned to say something to the person next to him, that person raised his hand and the king appeared in front of everyone.

-Sorry for the inconvenience.

-What do you want from us?!

One shouted angrily.

-I apologize for not giving a reason, you chosen ones of the gods.

It was a period of more than 200 years after the hero Arthur defeated the demon king Kamikaze, the 7 mages of the Seven Great Elders had seen that other dangerous things were starting to appear, and that day had come.

There were many demons from the demon king's era that had begun to return, including some of the demon king's strongest subordinates, they had continuously destroyed and ravaged the entire world, the king summoning them here was nothing more than helping them destroy them all!

-Hey, why does this feel like an Isekai anime?

-Hey, are we going to have a super powerful system and ability?

-That would be great!

The others began to discuss this with each other, and as for Komine, she saw Komasu looking for something and came over to ask.

-Hey, what are you looking for?

Komatsu heard this and turned around, seeing Komine.

-Komine-senpai, have you seen Akzuha?

-Akazuha Shashiki? Isn't he near you?

-Huh, I've been looking for him for a while now, but I can't find him anywhere!

-Huh!

Somewhere, Akzuha was lying in a smoking magic circle, he slowly opened his eyes and stood up.

-Where is this?

Akzuha stood up and looked around, the place he was in was a very large, dark cave and it was clear that there were some not-so-good things existing in this place.

-Hey, is anyone here? Komatsu, where are you?

Akzuha kept calling his friend's name but there was no response except for his own voice echoing back.

-Strange, where the hell am I?

Akzuha closed his eyes and felt the life energy in the line, this ability he had practiced using since he was 15 years old.

-There's no one else but insects and... monsters?

-Hmm, this teleportation gate brought me to a strange place

Akzuha continued to go deeper into the cave, searching for any sign of an exit. Suddenly, he heard the faint sound of running water in the distance. Following the sound, he stumbled upon a small stream formed from the dripping water. The water was cool to the touch and gave off a faint light. Akzuha was about to bend down to drink when he noticed something strange about the water. It seemed to be vibrating with an unnatural energy. He hesitated, curious but also wary.

While Akzuha was contemplating whether to investigate this strange water source, he heard footsteps approaching. He quickly hid behind a nearby rock and watched as a group of goblins emerged from a dark tunnel that he had not noticed before. They were holding a torch and seemed to be heading towards the stream.  Akzuha's eyes narrowed as he realized that they were not ordinary goblins, but a group of heavily armed guards protecting a well-dressed person. Akzuha's curiosity aroused, Akzuha began to follow them.

-What is this?

-I can feel its life force, it's neither a god nor a human, this filthy thing is... Goblin?

-Hmm, I've read some works about the reincarnation genre, this is the first time I've seen the most disgusting creature in the flesh.

Akzuha was about to touch it when suddenly two arrows flew towards it, with extremely fast reflexes Akzuha caught them and threw them towards the two Goblins in the distance.

-Looks like I was right about them traveling in packs.

Akzuha snapped his fingers and created a fireball, an ability that Izumo had taught him based on the fire control ability of the sun goddess.

-Eat this, you bastards.

The flames flew towards the remaining Goblins and burned them instantly.

-Delicious, now let's find a way out of this cave.

Akzuha began to look for an exit.

As Akzuha searched the cave, he kept his eyes and ears open for any danger. His senses, honed over years of training, were always on high alert. Suddenly, he heard a faint sound coming from a nearby tunnel. It sounded like someone was humming to themselves.  Akzuha cautiously approached the sound, weapon at the ready.

As he approached the source of the buzzing sound, he saw a small figure wearing a tattered robe, sitting cross-legged on the ground. The figure was buzzing and seemed to be meditating.

-What the...

-Oh, a mean stalker.

The girl saw Akzuha and disappeared, Akzuha was startled because she had disappeared but what he cared about now was finding a way out of here.

He felt a cool breeze blowing gently on his face, which confirmed that he was getting closer and closer to some natural gas source. He continued to follow the wind to search for a source of contact with the outside world.

Akzuha sensed something, he pressed his ear against the wall when suddenly the wall collapsed and Akzuha fell into an unknown place.

-Ahhhh!!!

Akzuha's scream echoed throughout the cave, after about 5 minutes Akzuha landed in a house.

-Ugh!

He passed through the ceiling and landed on a potion making potion.

-What the hell?!

The owner of the house was surprised because he didn't know what had fallen into his pot of medicine when suddenly Akzuha jumped out of the flap and scared the woman.

-Who are you?

-It's a long story.

Another person heard the noise and rushed in, saw the stranger and immediately pulled out his sword and pointed it at Akzuha's throat.

-Who are you?

-Now, now, calm down!

The girl stopped the other man.

-Who are you?

Akzuha kept calm and tried to explain the situation. He told them that he was lost in the cave and accidentally got dragged down here. He swore that he had no intention of causing harm and just wanted to find a way to return to his original world as soon as possible. He added that he knew about the existence of things like magic and gods, so he understood that he was in a very strange world, maybe even a fantasy world.

She heard Akzuha say, suddenly Akzuha asked her.

-I'm Akzuha Shashiki, you are...

-I'm Minamoto Yuki, are you from another world?

-Yes, you too?

- Um, may I ask what era you're from?

- Hmm? I don't quite understand.

- I'm a person from 1980 and this person is Tesuo Minamoto, he's from 1945 BC.

Akzuha realized that he was trapped in a strange world where time didn't seem to follow any rules. The people he met seemed to come from different times in history. Although he was very surprised, Akzuha still tried to stay calm

- Um, so time is not even?

- Exactly.

- Then Akzuha-Kun, what era are you from?

-Well, it's the future, 2024.

The other two were quite surprised to hear that, Akzuha noticed their expressions and asked.

-Hey, is there someone else from around 2024 who came here?

-No, there are only a few people from the year 2000.

-But... where is this?

-Oh, my bad for not telling you clearly, this is what we call... a singularity.

Yuki pulled the curtains open and revealed a view of a village.

Akzuha looked out and saw many people living, some were wearing old clothes, some were wearing modern clothes.

-But...why do you call it a singularity?

Yuki heard that and immediately took out a special bag and poured it towards the flap, a diagram of space appeared.

-Let me explain.

Yuki explained that a singularity is a place that does not follow the normal rules of time and space.  It is a place that exists outside of time, where the normal laws of physics and logic can be broken. For people from different eras, the Singularity is a strange combination of past, present, and future, a place where anything is possible.

-In the teleportation magic, there will be something called a singularity, it appears when the specified number of teleports is exceeded or overloaded, the space will automatically push the excess out of the teleportation space and send them to another place, and perhaps all people like us will be teleported to this singularity.

-So... you and the people here were pushed out and sent to this singularity?

-Yes, that's exactly it.

-Is there an exit to this place?

-Yes, but leaving here is impossible.

-Why?

-The singularity has no exit because it is a place completely isolated from the outside world, which means there is no way to leave here. People are brought here and trapped here forever, with the risk of losing their memories and themselves, leading to insanity and becoming insane.  Everyone here has tried to find a way to escape the Singularity but failed.

- But it's not like there's no way out, there's a gate that can lead us out of here, but these guys are guarding the gate

She took out some pictures to show Akzuha.

-What's this?

In the picture were images of a series of strange creatures, Akzuha could identify some creatures such as Goblins, skeleton ghosts, slimes but the others were completely unrecognizable.

-What are they? I can identify the others but the rest look quite strange.

-These are creatures that we call them God Insects.

-They were originally just normal creatures but something strange in this place caused them to deform and evolve.

-Something?

-Why does it sound quite like a dungeon.

-Yes, because this is a dungeon.

Akzuha was surprised, Yuki continued.

-This singularity has the shape of a dungeon, made up of 100 layers, one layer has an infinite width, the last layer is where the thing that causes the creatures here to deform.

-Wait, how do you know?

-This was originally a place where other people lived, they were the ones who came before us and they recorded all these things.

-Hmm, is that so.

Suddenly, the big bell on the church in the distance rang out.

-What's going on?

-That's an alarm.

-We use it to alert the people here that mutant monsters or other monsters are coming.

Yuki turned to call out to Tesuo but he had already disappeared.

-[When did he move, he's so fast]

There was an explosion in the distance and Akzuha jumped out of the window and rushed towards it.

-Wait Akzuha!

Akzuha ran through the houses and had to constantly avoid the debris from the houses that were flying towards her.

He ran to where the chaos was happening and saw that the thing destroying everything was a deformed Hercules beetle.

-What is this!

Akzuha suddenly found Tesuo slashing at its shell but his attacks were completely futile.

-Get out of the way Tesuo-san!

Akzuha shouted and threw a flame towards the beetle, Tesuo saw Akzuha shouting and dodged to the side, the fireball exploded and blew away a block of the town, the people around there had been evacuated so it could be said to be completely safe.

-What the hell-

The smoke cleared and revealed the beetle was still alive and hadn't even taken any damage.

-Idiot, this thing has been enlarged, its durability is strong enough to withstand level 2 fire magic!

-[Magic?  Hmm, it seems like I still don't know how magic works here]

While Akzuha was thinking, the scarab sent Akzuha flying, passing through the houses and falling into a nearby weapon smithy, the blacksmiths who were still working were startled when Akzuha crashed through the smithy.

-This idiot!

The scarab continued to charge forward but Tesuo used his Katana to block it, but its power was too great, he was unable to withstand it.

On Akzuha's side, he was looking for a weapon to deal with it.

-Not this one.

-Ax? No.

-Sword? I'm not used to using this.

-Shield? I'm not a shield hero.

-Is there any weapon that can be used?

-You can use this.

An Elf girl dressed as a veteran blacksmith tossed a dusty sword to Akazuha.

-Use "Moonlight Slash" to kill that thing, we have a lot of work to do.

Akzuha nodded and rushed towards the other bug, while the girl sighed and went inside.

Akzuha rushed towards the other bug, slashing at it once, its shell was very durable but strangely this jet-black sword could cut through it.

-Demon Sword, First Form: Demon Cry of the God - Akuma tekide kanashī.

Akzuha retreated and slashed at it, it looked normal but in fact he had launched thousands of slashes in 0 seconds,

The bug was pushed back immediately, it was cut into pieces and turned into a mass of mush, Tesuo on the side was very surprised.

-A-Akzuha.

-Hey, are you okay?

Akzuha reached out and pulled Tesuo up.

-How can you do that, considering its strength against you, you can't destroy it.

-Well, it's simple, not everyone in another world is weak.

-In the old world, I was much stronger than normal people anyway.

Akzuha turned to the pile of slime.

-Is this one the only one?

-Yeah, even so, it's still just a newly grown one.

Before Akzuha could understand, Tesuo walked over to the beetle's corpse and picked up a piece of its wing.

-Adults usually have darker shells, this one's shell is quite pale, it seems like it hasn't been around for long.

-Is your color really that dark?

-The bugs down here, when they're fully grown, have two forms.

-I've seen two forms before, and it's hard to deal with, but now I have to go to the other guard area to see if there's another one that's lost, so you should go ask Yuki.

Tesuo finished speaking and turned around and quickly ran towards the other guard area.

Akzuha grabbed a broom from the other side and tried to clean up the mess, a while later some of the villagers came to help him.

Tesuo walked quickly towards the other guard area, while Akzuha looked for Yuki to talk. What was Yuki doing in her house.

*Boom!*

-Failed again.

Yuki was trying to create a medicine that could heal the wound caused by another monster down here, she was creating it when Akzuha suddenly walked in...

-Yuki-san!

*Boom!*

Because of that surprise, Yuki accidentally used something else wrong, resulting in another explosion.

-Akazuha...

-...I'm sorry...

-*wipes face* next time please knock, oh, and that's for later?

-Ah, well, for now, that thing has been destroyed, Tesuo is on his way to where it went earlier.

-Well, it seems to be quite difficult for him, he has just recovered after being very sick.

-Oh, Yuki-san.

-Hmm? Is there something wrong?

-Oh, I just wanted to ask you something, if you don't mind.

Akzuha started telling Yuki about her doubts, about this dungeon and the monsters here, Yuki nodded and said.

-I understand, but didn't I tell you a few minutes ago?

-I forgot, I'm sorry.

Yuuki sighed.

-Then I'll explain it to you again.

Yuki pulled out a board and started drawing something on it.

-This is the dungeon.

She pointed to the drawing on the board, a circle and below it were many other circles.

-You didn't use that medicine?

-It's powder, and I'm out of it.

-This dungeon has more than 100 areas, each area will be arranged from top to bottom, we are here, the area at the top is here.

-It's like an ocean, the further down you go, the stronger the monsters below will be, the ones above here are just bugs living on the ground, and the things at the deeper levels are all monsters. They are too strong for those of us living on the upper levels to destroy.

-To go to the next floors, you will have to enter gates like this.

Yuuki drew a gate.

-Wait, didn't you tell me that was the gate leading to the exit?

-I forgot.

-Huh.

-Can I apologize now.

-In short, the exit is here, the 100th floor.

-But, has anyone reached the 100th floor?

-Have...

-Who is that?

Yuuki was silent for a moment and then she answered.

-Ilivan Vancou, we call him the strongest man in the singularity.

-He is a man with power that can be said to be like a god.

-How do you know about him?

-An old man in here told me, he was Ilivan's comrade and he was the one who told me and even the whole village about Ilivan's legend.

-Wait, didn't he escape with you?

-Only Ilivan escaped, he said that when he got out, he would find a way to free the people inside.

-Is that so.

Akzuha was silent for a moment, but then Yuuki caught his attention, she gave him a medicine.

-This is...

-Give it to the farmers in the North for me.

-Oh, but that place is too far!

-I'm fine, hurry up and go to work.

Akzuha could only sigh and immediately rushed out of the house, heading towards the North of the village.
