"This is the ruins of the ancient civilization Ishtar...."

Since then, we have driven Kobda toward the ruins that were visible above the horizon.

After a few hours, we were standing in front of the ruins.

"But it's more like ruins than ruins."

I nodded quietly to Lily's line, which murmured next door.

Certainly. I expected more solid structures from the ruins.

But what we have here is literally ruins, piles of rubble.

What was once a huge building was buried in the sand, and all the ceilings were grown from the ground.

Other rubble and semi-destructed structures appeared here and there, but none of them left much shape.

"Ancient Civilization Istitutes... I've heard fairy tales and stuff before, but I didn't think I'd ever see more shadows..."

"Does Fitz know about Ishtar?

"Yes, but all I heard was a legend, and I don't know how it actually went. I hear Ishtar has been the most evolved civilization since the beginning of the world."

"Evolved....."

"I hear you had more technology than we have today. A vehicle that flies in the sky, a vehicle that dives in the sea. I heard that there were other tools for civilization development."

That's amazing. When I came to this world, it was just a ride that reminded me of the medieval times when I said monsters and carriages.

A flying vehicle was a fairly advanced civilization, wasn't it?

In fact, vehicles that fly in the sky on Earth have been made since civilization developed considerably.

"But I heard that such a developed civilization was destroyed overnight."

"I heard that too. I'm sure I destroyed it."

"The demon king of the time, Fraswerg?"

It was also something I had heard from Alicia before.

Ancient Civilization Istitutes. The highly developed civilization is said to have perished overnight.

It was destroyed by a presence called Fraswerg, the demon king of the time.

I don't know what kind of monster he was, but if he destroyed civilization overnight, the danger would be at a level completely different from the monster I knew.

Isn't that better than your mother's SS rank? I'm too anxious to even say that.

"Well, anyway, there's only ruins left."

Lily is right, what we have here is nothing more than wreckage.

I didn't even know what to look into.

"Even if there were any ruins left, many adventurers would have already visited and taken possession of the civilization that was once destroyed. There won't be anything left..."

"Certainly...."

Fitness is right, and even if there was something left, a lot of adventurers would have already come here and taken it home.

There can't be anything left where we came here.

But something from this place still haunts my chest.

Something other than that remains here.

"Phew!

And it seemed the same with Rock, jumping big enough to find something.

"Rock, what's going on?

"There's something here!

As guided by the voice of Locke, we gather at the place where Locke was.

When I saw it, I didn't think there was anything in the sand a little far from where the ruins were.

"What's going on here, Rock?

When I asked, Rock put his hand in the sand at his feet. And then...

"Wow!

The ground where Locke pushed his hand swallowed up Zubuzu and Locke's hand, and Locke disappeared into the sand.

"Heh?!

"Hey, just now...?!

It was us who were confused, but he immediately murmured as if Fitness had noticed something.

"A camouflage that applied sand hell rather than a hidden path...?

Sand Hell. It's called Ant Hell.

Does that mean something's down here?

"No, I can't leave the lock alone either way. Let's go and get him now."

Yes, it is.

Everyone seemed to agree with me and quickly jumped into the place where Rock was swallowed.

Then, the ground that was flat just now swallows us up like a bottomless swamp, and the next moment, you can taste the feeling of sniffing into the sand.

Then I visited the feeling of being thrown into the air. As it stood, we fell to the ground just below.

Uh-oh, surprisingly close to my feet.

It wasn't that high, so there was little damage to the foot.

But what surprised me more than that was the sight in front of me.

"This is..."

There were countless ruins hidden in the ground.

It was literally the shape of an underground empire.

It can be seen that some ruins, like others on the ground, were semi-destructed and collapsed, but some were hidden in the ground almost intact.

"This is... amazing. The ruins on top are literally fake. Most of it was hidden in this basement...."

Either it was hidden underground by years of sandstorms, or it fled to the basement on the verge of the destruction of this civilization itself.

"Pah, that!

With that in mind, he points to a ruins of rock that had entered this basement as soon as possible.

Most of the exterior is intact compared to other ruins and is much larger and larger than other ruins and buildings.

Speaking of which, there was a castle-like building.

"... is that it?

Rock nodded silently at me asking.

I didn't really have to check with Rock, but the moment I saw that building, I felt my body tremble for some reason.

That's because my instincts realized there was something there.

And that's what led me to this place.

When I felt that way, I tapped my cheeks to firmly support my trembling body, and looked at the faces of the people around me again.

Needless to say, everyone's expression was to prepare and follow me.

"- Okay, then, everybody. Explore the center of the building."

"Roger that!

"I'll take care of it, Kyo."

Leave it to me, brother.

Yeah!

After hearing each response, I set out for the ruins with my friends.
