I'll talk to your mother that night because neither your father nor brother Odie is back.

"Of course I have a good magic stone for you. You haven't given me anything for my birthday in years, have you? That's why I did it. And this is my last birthday present. It's a treasure enough to spend a lifetime on a birthday present.

"Yes! Is that so amazing!? Thanks! What demon stone is that!?

"Ugh, it's Evil Huge Trent. I asked Master Fernando for this day. By the way, Elizabeth was the same. Although I used something else for Urien and Odillon.

"Wow, that's amazing! Glad to hear it. I figured you'd be compatible with Evil Huge Trent because you usually use his wooden knife?

"Really? That's what I have. So size and performance, but what do you want to do? You can do whatever you want, right?

"I don't care that much about size, but I hope time doesn't go as far as possible. It would be nice to be able to save it for a long time.

"Okay, so let's do a magic check for the first time in a long time.

That's what my mother put her hand on my forehead and umbilical cord.

I do all I can to carry out the Smelter Circulation.

"Holy shit!

My mother bounced away from me as if she were going to fly.

"Wow! It's so magical that I don't know the cap anymore! Besides, if you say how smooth the Alchemist Circulation is, it's beyond skilled court magicians!

I can build any magic bank I want!

When I worked out the speed and quantity, I got to the smoothness. This would be one truth.

"Good. Can you even make enough to stop time?

"Yeah, yeah, I can make it. In that case, I think it will probably be about the size of this house.

If it's not about performance, it's about the size of a whole tonut, at least.

"Wow, that's amazing! Oh, but you lose half your magic, don't you? Are you all right?

"No problem. 'Cause that's all the magnitude, even with reference to the magic I've just weighed a little. I don't think we're going to lose 20% if we don't set it bigger than that.

"Ah, that would be reassuring. Because if you fly in the sky, if you have low magic, you will fall.

"Then write down the detailed specifications.

Combine this with Demon Stone and money and submit it to the Magic Librarian.

Oh, just show the specifications to the teacher tomorrow. Because I'm sure it's going to be hard to prepare.

"Yeah, I will.

Ready? Well, I guess there's a lot going on.

"By the way, you shouldn't let living things in. Because if you accidentally let a highly magical demon or something in there alive, it's gonna be a big deal.

"Huh? That's scary. What's gonna happen?

"I don't mind when the magic of the owner is full, but if the magic falls due to a series of magic or something, and it goes below the magic of the demon, it will replace itself with that demon. So you can lock yourself in the magic chamber. If you are lucky enough to recover inside and increase your magic power over demons again, you can come out. But no one can rest calmly in a magic library with no sound, no light, no earth.

"Wow, that's scary. So what if that's when the demon gets killed?

"That's luck, too. For example, if an adventurer killed you, it might help, but if some other demon ate you, it's in the belly of the demon you ate when you came out.

Or nobility. When you die, the contents are set to disappear, so you disappear when the replaced demon dies.

"That's scary. I knew I wouldn't let the creature in. I'll set it up.

"I like that. I don't think that would happen first if you had as much magic as Curse, but it's still dangerous.

I'm glad I can use your fantasy item box, but there's something intelligent inside. How much power is the Demon Stone, the Gold, and the Magic Library of the civilian population?
