A while after entering the second generation Demon King's dungeon, I noticed that the environment had changed compared to the morning.

"Matango is not coming."

The assault on Matango, which had come out of the wall and floor and came into the air, had stopped.

For the time being, they will appear, but they will not show the will of the hostile.

Or rather, I'm bowing to us.

"... What's going on, this?"

"Oh, this is because Chrono has taken the contracted stone that had created and used the monsters. Its dominance has been activated."

He was told that it was a stone that controlled monsters. However,

"Can I use it just by taking it? What is a contract seal stone?"

"Yeah, I can't just take it. Heritage can be used. ''

So, why is the power of the contracted stone being activated, I pick up the stone that I keep in my pocket.

The stone was faintly wrapped in a familiar black light.

Or rather, my chains were covering the stone.

"Um, this chain is wrapping around on its own. What is this?"

"The chain shows that Chrono is the owner. You have been recognized as the owner of the Demon King's legacy. Congratulations!"

"No, congratulations. What would happen if you weren't recognized as the owner?"

"In that case, it just has no effect. This time, the effect is exerted, but the control of the monster has been transferred to you.-Oh, but just because you own it does not make this contract Monsters don't attack, they don't control it.

So that's it. I don't know much about this contract or its detailed uses, but I've found that this demonic heritage can also be used to avoid monsters.

...... Unlike the gatekeeper, Matango will come out even if you defeat it, and it was a little troublesome.

It is a great help to safely navigate the dungeon, even if you can't handle it.

"Then, why don't you walk looking for Mr. Salamad?"

"Yes, let's do it. I'll catch up if I find a door with an open sign and go in."

The dominator's guide states that the rules should keep the door open when infiltrating the dungeon. This is to make it easier for people who come later to know where you are.

So, this time, I will follow the open door.

"I'm gonna go. Sophia will tell you if you hear something strange in the middle."

"Yes, I understand. Vampires will go with full hearing."

Vampires have the highest level of hearing among demons.

With her, you'll never miss a voice.

With that in mind, I keep moving forward in the dungeon while being squeezed by Matango.

… I mean, the effect of this contract seal stone is really amazing.

There was no sign of Matango attacking even if I went down to the second or third level.

Thanks to that, I came down to the fourth level without stopping,

"Wow, gatekeeper, you're here too."

I stopped myself in one big passage on four levels.

There were six gatekeepers in front of the door.

For the time being, I bring a wooden stick, but it's a bit painful and dangerous to deal with multiple bodies.

He had to cooperate with Liza and Sofia to defeat him, but he looked tired,

"Oh, okay, okay. If you're a chrono, I think you'll be able to get up just by holding up a contract stone."

Liza laughed and said so.

I thought the stone would only control Matango, but apparently not.

...... Is it true?

Despite doubting, I raised the contract stone and went near the gatekeeper. Then

"..."

The gatekeepers immediately knelt at me.

The quiet, slightly intimidating sight makes me a little nervous.

"Um ... Liza-san, is the power of this contract stone too strong? It works on all the monsters in this dungeon."

"That's right. It's the Demon King's legacy. It's natural to have strong power!"

Liza says lightly.

I was looking at a mattress that could sleep well, a closet with infinite clothes, a legacy of the Demon King that seems to be useful in everyday life, so I did not think that way,

…… If you think about it, mothercores and other ridiculous things are also Demon King's legacy.

I realized that while I was now.

"Somehow, the Demon King's legacy is amazing."

"Ah, that's right. I'm glad you understood that. Actually, it's not just the power of the Demon King's legacy."

"e?"

Liza looked at the contracted seal stone and looked into my eyes.

"The reason I let the gatekeeper kneel down so far is because you have control over the Demon King's heritage and you can't usually use it in this way."

"Really?"

I don't know because I've never seen other people use it.

"Yes. For example, if Professor Dante uses it, I think it's hard at all to suppress Matango. So what's the result of Chrono's power? It's a good idea to remember carefully. "

"... I see. Well, I remember well."

"Okay ... huh, this activity is part of the lecture. I'm glad I was taught something new."

Lisa smiles and smiles.

And, I realized again the power of the Demon King's heritage, and with Sofia, dive deep into the dungeon.
