Walk straight down the aisle, ignoring Elvest.

"Hey! You're listening!

"That's annoying. You're alive."

Seems like you still want to say something, but there was a vast cavity ahead of you through the aisle.

Above, the town is visible.

"Ko, this is..."

Elvest groans blindly as he looks up over the sky.

Me and Alice were surprised to see the sky too.

Because it was far beyond my imagination that the place I thought was on the ground until earlier seemed clear from below...

"That's an amazing sight..."

I didn't realize it when I was on the top tier, but the sights of the building from below are amazing.

I have no idea what method of construction I made, but I can only understand that it is a building by advanced civilization.

In the Agarta world I lived in, building a house out of wood or bricks is common, but this is clearly something different.

"Are you taking the same way as Nautilus...?

"Nautilus?"

"It's Nautilus, a spaceship that runs through space. You've seen it in the Duchy of Alto, too, haven't you?

"Oh......"

Nodding and remembering.

About when I fought Kaisardo, who has raided the College of Isperian Nobility in the Principality of Alto.

At that time, when Kaizardo retreated, the ship he was on was probably called Nautilus.

"I mean, that ship is a relic of the age of divine civilization?

"Right."

As if to affirm my words, Elvest answers bluffing.

Nevertheless, how Kaizardo uses relics from the age of divine civilization......

There's still something I don't know.

"Dear Elvest, Mr. Kazt! Look at that! You can see the building."

As we walked out of the aisle, the great cavities lit up one light after another, and there was a building floating white in it.

It's a triangular building.

It reflects the surrounding sights, and I can't see the joints.

"In the meantime, let's take a look at that"

"Hey, check this out"

"- Hmm?"

Elvest is pointing to the sign on the left side of the aisle.

"The central control system for life?

"Apparently, this is where you manage something."

"I know that..."

Elvest speaks well, but from the letter it would be about life.

The question is what is it referring to......

"And it's a strange place,"

Alice tells me she's approaching.

Indeed, she's right. The place where we are makes it seem like clear air is flowing.

It doesn't smell like precious metal or dust like when I was in the dungeon.

Tell you what, it's like making you feel calm like you're in the woods...

"Anyway, let's move on."

"Right..."

Either way, I'm not going to get any more information.

First, you'll need to take a look at that life central control system and the dots.

I can see the whole of the triangular cone building that was looking white as we approached the building.

"That looks like a pyramid."

"Pyramid?"

"Oh, it seems that the literature gathered by Master Kaizardo once glorified mankind had plans to migrate to other planets. It was called a pyramid that stood up..."

"Pyramid..."

"Well, I don't know if the people of the divine civilization were calling buildings by that name."

"- Hmm? Then where did the name pyramid come from?

"According to the literature, 3,000 years ago, Ars, the first Valkyrian emperor of the continent of Laurencia, spread from when he called it that. Well, the emperor named Ars is quite a substitute, he was developing the magic of time manipulation..."

"The magic of manipulating time..."

"He seemed to have bragged that time had come and gone many times, but the facts remain a mystery."

"I see..."

"Dear Elvest, there is no entrance or exit!

"Hmm..."

However, as Alice said, I don't see any place in the building where I can get in and out without any joints.

On one side is a huge building of 200 meters.

"Let's split up and find the entrance."

"No -"

I put a wooden knife in my hand with a cuttoe to the surface and release a thrust.

The penetration with the wind thunder god activated can even be pierced by an iron plate with a thickness of 10 cm......

"The wooden sword..."

"You're crushed."

"Do I have to make it again..."

The moment he hit the mirror-like building wall, the wooden knife was shattered.

Apparently, it's not a normal building.
