"Hmm, you know a lot."

I snapped as I looked at the demon stone in my palm.

What's in your hand is a blue-colored stone.

No, should I call it a crystalline form rather than a stone?

Beautiful crystals like blue crystals were held in my hand.

I have been researching demon stones since then.

And there were a few things I found out.

First of all, the Demon Stone can be created with my magic.

That means Demon Stone may not be metal, but glass and other companions.

Why, because the flaming ore I took in Fox Valley could not be reproduced by magic no matter how much I tried.

Perhaps iron and other metals can't be made with magic, and given the strange properties of my magic that can make glass, crystals, etc., a demonic stone is closer to glass and such than metal.

And this demonic stone, but briefly, it sounds like a battery.

I was able to add more magic to the magic stones I made.

It was pale blue at first, but the darker the magic.

And vice versa, when there is no more magic from the demon stone, the color diminishes.

It may be useful to know how much magic is stored with one eye.

By the way, it felt like a transparent crystal when I was completely out of magic, so I think this is beautiful.

And then I'm going to take the time to create the magic that instantly mass produces this demonic stone.

I don't know what I would do that for, but it was to make a Zubari battery squeeze.

Magic stones can also be used as an alternative to magic restorative medicine.

but I'm hoping it will be easier to use flame ore than that.

I used flame ore to create balloons.

He blew fire like a burner by instilling magic in the flaming ore inside the balloon cloth, making it the driving force behind the hot air balloon.

The balloon ended the flight experiment with the immaturity of my maneuvering skills.

But the balloon's experimental data were the ones that led to it.

Because I was concerned when experimenting with flying balloons.

One is how to regulate the amount of flame that comes out when you pour magic into flame ore.

It was thought that it would be easier to use when it was better to put a lever or something on hand to regulate the momentum of a fire.

But that's only for now.

The thing that bothered me the most was that I had to keep pouring magic into the flaming ore.

At last, if a man with magic doesn't keep pouring magic all the time, there will be no fire.

This would be a bit of a problem.

If you blame me, you'd better have a mechanism that allows you to keep using it even if you're asleep.

Furthermore, there is no need to change the utilization time due to the size and magnitude of the operator's magic power.

Because I think this is bound to be a problem when utilizing flame ore besides balloons any day.

The existence of a demonic stone that can keep its magic for what could be a key item to eliminate it.

I decided to study whether there was a system that could connect flame ore with demon stone and make use of it.

Lord Ars, I want you to give me that magic stone to the awkward.

"What's going on, Gran? Nothing. I don't mind giving you the Demon Stone, but what are you gonna use it for?

"It is to be used for flame blast furnaces, Lord Ars."

"Flame blast furnace? What the hell?

"Didn't we talk a while ago? He said it might be interesting to try to build a furnace with flame ore. That's what I've been working on."

"Oh, speaking of which, I think I've managed to say something about being flexible about the idea... I told you then it feels like incitement, but does it make sense to use flame ore for a furnace, Gran? I'd be in trouble if it was a waste."

"Experimentally, the feeling of trying to make one is working, Lord Ars. I have tried using flame ore inside in combination with a highly refractory hardened brick. Essentially, if you have flame ore that can produce super high heat with magic, you can increase the temperature inside the furnace more than any of the existing furnaces."

"Hmm, it seems like we could do it differently, but okay. But wouldn't it be nice if it was working fine with that? Why do you need a demon stone?

"Wouldn't you be able to blacksmith if you were pouring magic toward a flaming blast furnace"

"... Indeed. If demonic stones can replenish the magic of flame blast furnaces, is it easy for workers to work? Fine, sooner or later, I'm going to spell the Demon Stone so the others can use it, but until then, I'll keep the Demon Stone I made for Gran."

"It's a pleasure, Lord Ars. This is going to make the awkward man's imaginary weapon."

"Oh, are you finally going to make it? What are we gonna do?

"Pfft. Would you like to hear it, Lord Ars? I still think it's a good idea to build a sword at first. The awkward man's knowledge, experience, and skill will make the best sword ever."

"That sounds interesting. Let me give you a tour, too."

"What are you talking about? Lord Ars would also like a hand in making swords. Instead, we need the power of Lord Ars."

"My power? Doesn't seem like much I can do with a blacksmith, but fine. Shall we just do it, Gran?"

Thus, having separated myself from the study of demonic stones, I went with Gran to the newly built flame blast furnace.

And we were supposed to build new weapons.
