Guided by the professor, I was in front of a room in the basement of Demon Castle.

"Is this a special advance class room?"

"Oh, there are already more than a dozen in here. You're the last."

While talking with the Demon King, it seems that the ordinary special selection was over.

"This class is the last for you. I will start the initial explanation as it is, so if you enter, please sit in your favorite seat."

"Oh, I understand."

Then I open the door and go inside.

The room, with its stone exterior, was lined with many pillars.

Several long desks and chairs are placed along the pillars.

As you proceed while thinking that it is a very strange room shape,

"... It's a ghost, Chrono, who hijacked a mother core in his dungeon ..."

"It looks like a human, but it has strange waves. It's creepy but terrible."

A whispering voice of those sitting ahead was heard.

It's weird to be a monster in the dragon genus who has dragon claws and scales that are harder than iron, or a weird mage who is cursing at the clan level. I sat down. Then

"Hello. It is a great hot stock, Chrono-san"

A woman at the same desk came and called.

The face is familiar.

"You, Sophia, are you a vampire?"

"Sofia is fine. Chrono-san."

The vampire girl smiled and smiled.

This child seems to be a very friendly type.

"Thank you, Sophia. But I often remember my name."

It's hard to remember a demons without such features.

"You're a top performer this year. It's natural to remember. I'm rather honored to remember my name."

"I'm the top?"

"Yes, that's right. The professor said that this year, or even the best in history, was unprecedented to replace a whole mother core."

Seriously, I held my head in my hand.

It's really unexpected that such a story has been around since the first day.

"Isn't there any other person who made a hundred dungeons?"

"Yes. I'm the tenth and second place. I'm the only one more than me. So I'd be grateful if you could take a closer look!"

Sofia said, shining his eyes.

Even if I have that kind of expectation, I can't do anything. When I wondered what was going on,

"Well, you guys. All special advance classes are now complete."

A professor standing in the center of the room exclaimed.

And we continue words without waiting for our reply.

"From now on, we will give an initial lecture to those in the special advance class! We will teach you the basics of demons, how to operate dungeons using magical power. Listen to what you want to remember!"

In the words of the professor, everyone in the special advance class listens at once.

"Every demon has the power to move a dungeon with images. So the basics of manipulating dungeons are images. What kind of room do you want to make and what kind of movement you want to make. And draw it out in your head and say it out.- Well, it's difficult to say it, so let's practice it. "

With that said, the professor points to one of the pillars in the center of the room.

"This room is actually my dungeon. If you want to control it, you can do this:-Break it!"

With his words, the professor raised his arm. that moment,

-Baki

At last, the pillar connecting the floor and the ceiling broke from the center.

"Oh……!"

Cheers rise in the room.

"If it's in a dungeon, it's easy to manipulate and break it with the landlord's authority. With this power, we demons can make the dungeon wider and bigger. "

The professor approached the broken pillar and stroked it with pom-poms.

Then, the pillar that was broken by itself is restored.

It seems that you can freely break and return your own dungeon.

I don't want to expand my dungeon anymore, so I didn't know anything about this,

It's interesting to tweak the structure.

I keep listening to the professor's explanation.

"Now, this is my dungeon, so it's natural for me to break a pillar ... As you get used to building dungeons, you'll be able to manipulate even the dungeon objects of others. I prepared a pillar for each person, including knowing the power of the person.

At the same time as the professor's words were over, the demons in the room began to touch the pillars all at once.

Breaking, cracking, cracking, loud voices and sounds fly. Next to me,

"bented……!"

Sophia is touching the pillar.

Then a crack starts to enter the pillar from the place she touched.

"Oh, as expected, Sophia, the creator of the A-class dungeon!

"Oh, thank you, Professor!"

Apparently, it is possible to manipulate objects in the dungeon just by thinking and thinking.

The demons have the power to move dungeons with images.

I look at the thick stone pillar next to myself.

I have no idea how to imagine breaking such a huge pillar.

If you hit it, your hand is likely to break, and you can only imagine your weapon breaking if you hit a sword or stick.

If you break such a pillar, would it be like using explosives or something?

Or maybe the ceiling is shifted and the pillars are broken.

"That's right. If the ceiling moves or moves, the pillars will break."

The moment I saw one pillar while tweeting,

-Bang.

With a light explosion, the pillar twisted on the spot.

It is as if the ceiling or floor had moved and the load was beside the pillar.

"that?"

And that's not all.

"Wow! What's that, all of these pillars are suddenly broken!"

"It's my place! I mean, the ceiling is moving!"

Apparently not only the pillar in front of me, but all the pillars in the room were broken.

"Oh, hey, isn't the ceiling turning around the place where Chrono is !?"

"Well, I'm sorry. What's going on ...?"

It's strange. I did say that the ceiling would move, but I didn't think it would be like this with just one word.

When I look overhead,

"Ku, Chrono-kun, you're terrible. No matter how much of my dungeon, you can't control the room so far."

The professor was looking at me with astonished eyes.

…… No, I said, "I hope the ceiling will break if it moves."

I never thought it would really work.

"That's not it, professor! Pillars are all broken, but this one doesn't fall down on the ceiling, right?"

"U, um, that's fine, Chrono-kun. In addition to pillars, my dungeon has a mechanism that supports the ceiling. It doesn't fall immediately."

However, after saying so, the professor spread his hands widely and made gestures to support the ceiling.

"Oh, that professor? What are you doing?"

"Um. The main pillar has been completely broken by Chrono, so if you don't support it, it will fall faster.-If possible, you'd better evacuate!"

The professor's forehead was sweating.

I feel so sorry.

"That's something."

"No, no, good. I'd rather thank you for seeing your power."

"That's right?"

"Oh, the lecture on how to extend the dungeon is over.-So, today, we're ending today's lesson! ! "

"Yes, yes! I'm sorry!"

And we left the room, as if hurried.
