"So, what's the demon you knocked down?

minutes after the school contacted me.

"It's called an arc salpent, it's a snake demon."

"... you've never heard of it. Is that a 21-layer demon, too? Honestly, I can't believe how much school tells me, such as the 21 tiers of that labyrinth were attacked..."

"It's a bit of a special demon, but that fits. The Demon Stone is this.... By the way, technically, I'm not attacking. This is all I've defeated and I'm back."

That's what I'm gonna do. I'm gonna take out Arc Serpent's magic stone.

"... wait a minute, Matty, I didn't hear about that demon stone."

"Is that really a demon stone!? There are more than 50 centimeters..."

"In my view... you don't seem to make a mistake with demon stones. I don't think there's anything like this in the national treasure..."

Three people who saw the demon stone turned to face.

By the way, your sister, who seems like a receptionist, was summoned by someone right after that and left the room again, so now there are only four people in this room: me and Lurii, Alma, and the branch manager.

"Matty, you're turning into a national treasure mass production machine..."

"I think it's been a long time since Matty mass-produced a national treasure"

"But it's a little subtle..."

This demonic stone measures approximately 55 cm. Hopefully, I wanted about 3 more centimeters.

Whether or not it can be used as the main demon stone of the junction is a delicate point. The magic stone of "Hierarchist" is high performance for its size, but it also involves the nature of dragon veins used for magic sources.

Well, do you think about that later? If it's not enough, you can go get a new one.

"Subtle? Of that unusually sized demon stone, what the hell am I missing?

"I need a slightly larger demon stone, and it's not small enough. I'm sure the announcement will be made later."

"A demonic stone over 55 cm is a bit larger...? Apparently, I remember the word 'hey' by mistake."

... and so on, I heard footsteps again.

Soon after that, the door can be opened.

"I got the circular!!

The receptionist, who was called in and left, seems to be back.

Apparently something happened.

Trouble again...

"Now what!

"Matthias-Hildesheimer and his associates are talking about exempting them from taxes on labyrinth-related purchases. So, raise the buyout price for that..."

I thought so, no.

Apparently, we've received word about the rewards of the Demonic Crusade. I thought the procedure would take longer, but when I heard I was going to sell the labyrinth demon, did the principal arrange it earlier?

Still, you even exempt me from taxes when I sell.

"I can't do that. Taxing the trading of materials by guilds is an order from the state. How much did the school ask for?"

"That's not the second school, that's the circular from the Royal Palace!

"... from the royal palace, immediately? How strong or insane can it be, but for a schoolboy?

"I've barely been able to grasp the situation either, but I have the king's judgment, and it's the knight who delivered this, so I thought it might be real..."

"... oh. If I thought something was wrong, I finally figured it out. Was this a dream?"

It's not a dream. It's real.

- After all that noise, we managed to get the sale process done (even when we took the bodies together, we were bored, but they didn't buy anything but arc salpent. Apparently it was a missing material).

About 750 gold coins in total for what you could have bought on the spot. It's cheaper than Bottacrisode, but there's no price on this occasion for Arc Serpent (first, it seems it starts where we find out what kind of material this is), so we were put to dismantling and auction at a later date, and we were to receive the gold after the results, so that portion was added later.

If I have time too, I plan to be present at the auction.
