"What do you say, Gran? Is the Kyouo sword going to be able to reproduce it?
"... Kuh. I must say that it is very difficult at present, Lord Ars."
"Can't you? This flaming ore has become a material for the Nine-Tailed Sword, and you can't go wrong with that, can you? There will be no other unusual ore that reacts to magic and flames..."
"This flaming ore is not the problem, Lord Ars. The problem lies in the properties of this flame ore."
"Characteristics? That's the unusual characteristic of flames, but what's the problem?
"That's not true. The flames aren't a problem in themselves. But it's definitely not hard enough. This flaming ore is too soft, Lord Ars."
"Soft? It didn't feel like it in my hand, but isn't it hard?... Oh, I see. Is it supposed to be soft and unsuitable for swords?"
"Exactly. This is not a weapon for processing flame ore and using it as a sword."
"But you actually have a nine-tailed sword that can also be used as a sword, Gran. There's no way it's ever going to be possible."
"... you are right, Lord Ars. Awkward, it's burning. I will try to recreate this nine-tailed sword at all costs. So I'd like you to wait a little while until it's done."
"... hey Gran. I'm a little hard to say where I'm sticking up, can I ask you something?
"Why, Lord Ars. Is there any way you know how to make it? Awkward people are wondering if they are mixing with other metals, but there are other things they should increase the furnace temperature more when processing flame ore, or..."
"Uh, it's a stop, Gran. I'm so excited."
"Oops, I'm sorry about this. So, I wonder why it was. Was there something Lord Ars wanted to ask the awkward?
"Oh. It's not a question, it's a simple question. It makes a lot of sense to recreate the Kyouo sword."
"... what does that mean? Didn't Lord Ars go all the way to Urk in search of flaming ore? It's a little hard to understand that you don't suddenly need a Kyouo sword after you actually get the Flame Ore."
"No, well, I'd appreciate it if a magic sword called the Kyouo Sword could be mass-produced. But you don't have to stick to that. Nine-tailed sword that gives out an indefensible flaming sword. That's all I hear, it may be very strong, but knights who use it can attack at a distance. I don't care if you don't have a nine-tailed sword, you don't have to wonder if your aggression will change that much."
"But Lord Ars. That's how I got the flame ore even though I said it now. If you don't make the Kyouo sword, you'll end up working hard."
"You don't necessarily do that. The point is, I'm just saying that limited use of weapons isn't the only way to use flame ore, I... Research on how to make a Kyouo sword is good, but let's make something else, Gran. There seems to be a lot of better ways to use it."
"Is it another way to make use of it…. But no matter how they say to use a flaming ore...... Yes, how about using this flaming ore to build a furnace, Lord Ars? It might be interesting to try to create a furnace with unprecedented heat."
"Oh, nice. That's what I'm talking about, Gran. That's what I was trying to say. I have something to try and make out of flame ore, too, Gran. There's something I'd love you to make."
"Is this what Lord Ars wants the Awkward to make? This is going to be difficult. What the hell is that like, Lord Ars?"
"Empty. Let's fly into the sky, Gran. Use Flame Ore to make flying tools."
"... what? Let the sky... fly? What are you talking about, Lord Ars? How do you fly in the sky with flaming ore? Aren't you forgetting that it's a metal with flames?
"No, no, that's good, Gran. There's gonna be flames without fuel. He said he could make balloons right away."
Me talking to Gran in Vulcania.
He had obtained and brought home a flaming ore, even called phantom metal, in a place called Fox Valley, on former Urk territory.
I was talking to Gran about the flaming ore.
In the middle of it, he looks at me with faces like what Gran is saying when he hears what I've told him.
That may mean that Gran has never seen a flight capable vehicle either.
but I'm not.
When I saw the flaming ore that flames would come out in response to magic, the first thought was not the use for the nine-tailed sword.
From what I can tell, the flame ore only looked like an energy generator.
It's a mass of thermal energy.
Thermal energy.
That was the greatest benefit to human history in the world I've ever known.
And it has also been a driving force in changing the world.
This is true, for example, of the industrial revolution caused by steam engines.
However, it was not the steam engine that I proposed to Gran this time.
If you are looking for other ways to utilize flame ore in the awareness that it will be used for a nine-tailed sword, you should have more impact at a glance.
With that in mind, I've decided to make the impact that humans can only fly on the ground.
Well, the flame ore is mine, so I don't have the muscle to complain about whatever it's used for.
To be honest, it's totally my hobby.
Thus, I taught Gran the structure of the balloon as much as I could remember, and began making balloons using flame ore.
