The Other Side of the Last Boss

Ancient empire.

A country that supposedly existed thousands of years ago.

Mythical times - times when the so-called God is said to have existed.

There are multiple gods, and it is assumed that all of them perished by strife between gods.

Most of the humans of the ancient empire who obeyed God also perished.

The few survivors rebuilt a little over time.

In the process, however, all ancient Empire technology was lost.

History, culture.

What happened at the time?

What kind of person was there?

Few of those materials remain.

I've lived a thousand years, but it was a long time ago.

Naturally, I don't know the details either.

I may know a lot about Grandpa, but I couldn't help but ask him a lot.

You don't have to know them to use them.

There are many things that are said to be the heritage of the ancient empire.

There is nothing left on the earth of this world as a building.

Everything blew up.

It is proof that the war was so intense.

All that's left is the underground part.

That is what is called a dungeon.

The other is a building in subspace.

We came to a certain subspace.

Here is a giant tower that rises to the sky.

It is a crystal tower.

"Speaking of which, there was this place."

I look up at the giant tower.

The material of the building is still unknown.

The art of ancient civilization cannot be elucidated by the people who live today, but also by the Evil Gods.

It was clear that the entire building was pale and exerting some power.

"The ancient empire wouldn't have made this place for training. However, there is a defensive function working here that inhibits anything that tries to go back. And strong. So it's great for training."

Grandpa explains.

"Anything that challenges the Demon King is accustomed to training here. I also cleared up to 10 layers 50 years ago."

Celina speaks respectfully.

About five layers if you're a weak demon king.

Ten layers of clarity are approximate from the base to the top.

Seven heroes 400 years ago, you think Seven Stars cleared up to 15 layers?

"How many layers are there?

"I don't know. The current record is 15 layers, but it's also a mystery as to how far the 15 layers are located."

Grandpa Ya poses like you.

This huge tower is as big as the first floor.

Some devices are like elevators, and they don't know how far up they've gone.

The Euphorians will aim to clear 10 layers.

The objective is to check if there is that much change.

I look back.

Grandpa, Jeko, Selina.

That's fine so far.

"Why are you following me?"

I ask Adrigori.

"I heard you were headed for the crystal tower. If I knew up to 15 layers, I'd be a guide."

I couldn't go outside for a thousand years myself.

Except for my men.

Sometimes I went outside.

That's when I had the chance to come to this tower.

"I don't need guidance. We'll have fun anyway."

"Yes, yes. About 400 years ago. I don't remember anything about the inside."

"That's because you're an idiot."

Adrigori stuck in Jeko's words.

The two of them are silent, but naturally I'm through.

"400 years ago...... 15 layers?

Selina frowns and raises her doubts.

"And Jeko............. No, it's a common name in itself."

"I hear there aren't many modern humans who name themselves Jeko."

Grandpa nodded.

"Excuse me, but your name is..."

"I'm Adrigori."

Adrigori gives a seriousness.

"Huh...... lying!?

Selina is stunned.

"I don't know, have you ever visited this place for seven people 400 years ago?

"Hmm. You seem to notice when you give this much information."

Grandpa smiles bitterly.

"Ya still Seven Stars!

The Fourth Magic Disaster happened 500 years ago.

Humanity was ruled by the Demons.

That the state continues for a hundred years.

There were those who stood up against the ruling of the devil clan.

They were later dubbed seven heroes - Seven Stars.

The first brave men and dragon princesses of the north to rise in the northernmost lands are famous.

There are two mysterious figures in it.

Two dubbed warriors of light.

Adrigori and Jeko.

Yes, it's these guys.

I said the same thing at the time.

But I want to say it again.

How did this happen?

"Oh, I didn't know that. I'm sorry."

Selina hurriedly lowers her head.

"I'm just working as a person now. Never mind."

Grandpa says with a cool face.

"As I reached out to you in the Sixth Magic Disaster 50 years ago, Adrigori and Jeko also lent a hand to people in the Fourth Magic Disaster. That's all."

As an evil god, I do not want the annihilation of humanity.

The demon king of the Fourth Magic Disaster was not trying to destroy people.

So at first I just watched.

But a world that hasn't changed in nearly a hundred years is boring.

I decided to give a little help to the humans.

He gave man what he called the legendary artifact.

Gathered and trained the promising.

Adrigori and Jeko were responsible for such work.

When it's over, you can leave as a mysterious person, hiding who you are.

But what they were thinking made them stand out.

As a result, he joined seven heroes.

"Oh, that's Jeko's idiot......"

Adrigori tries hard to make excuses.

"Huh!? Even you would have destroyed a demonic group on your own in Norinoli!

"I'll just have to help you if you ask me to help you in front of you!

"Enough excuses for the first time in 400 years"

When I say that in disdain, they stop arguing.

"After 400 years, only those who have so much information will notice. So it's not a big deal."

Grandpa answered plainly.

Though unidentified people, they don't expect to live for hundreds of years.

Since the Fourth Magic Disaster, names such as Adrigori and Jeko have become commonly given.

It is common for a child to be named a hero.

So no one even notices if you name it that way now.

As much as Selina has noticed now.

If I had time, I would forget.

That's what I decided at the time, and that's what actually happened.

The nail stabbed him.

He said never defeat more than the top executives.

Oh, I ossified after everything else.

"Ha ha..."

Selina seems distracted and has no choice but to answer that.

"Let's just say we don't care and move on."

When Grandpa said so, he opened a huge door several dozen meters long with a huge key.
