After a while.

When a significant amount of iron ore had accumulated outside the tunnel.

Looks like the waltzes moved out of the hole and started their next task.

"Shh... that's my next task, but I'm going to charcoal the trees growing around there, crush and mix them with this ore, and then I'm going to heat them up, okay?

"What? Charcoal? What's charcoal... that black, well-burned one? Or the one you use when writing letters?

"Hmm, maybe it's the same thing for both of us, but for Lucia, it's easier to say" charcoal from the burner, "right?

and after answering Lucia's question.

Waltz approached the tree that was nearby......

When you grab it with your hands, it's like pulling radishes and carrots off the ground.

Zdwwwwww!!

And I gently pulled it out.

"Well, if you want to use it for testing, you can have as much as you want. So, Lucia? Burn this... hmm?

"............" Pocahontas

"Uh? Lucia? Are you breathing?

".................. Ha!

"No? Lucia, if you get bogged down while you're working..."

"Ugh, yeah... (after all, sister, unreasonable...)"

Lucia nodded with a subtle look at Waltz, who was swelling her cheeks as she swung the big tree in her hand.

In response, Waltz asked again.

"So, Lucia? Can you burn this tree?

"Yeah. I think you can burn it with fire magic... but it's a tree that's alive and damp, so if you don't dry it properly, I don't think you can burn it like a bonfire, okay?

"Yep. I don't mind that. And maybe... I don't think it's gonna burn."

"What..."

When asked 'can you burn' and answered 'can you burn', Lucia is confused when she says' can't burn '.

What the hell is Waltz saying......

Lucia's head seemed full of such questions.

You knew that...

Waltz replied with a bitter smile.

"This is a little experiment. You don't know that you need oxygen to burn things in the air..."

"Yeah?"

"I'll compare you to another story... Uh... suppose there's a candlestick with a fire, huh? And a cup... what happens if you put a jock like the one in the tavern from the top... you know what I mean?

"... the jock... burns?

"Well, alle, it's made of wood...... Not that, but if a jock doesn't burn, and you're not even wet by it, if you wrap a candlestick around a jock like that, does Lucia know what happens to a burning fire?

Though I would have liked to have asked what would happen to the candle fire in it if I had slowly placed a glass glass glass glass glass glass from the top of the candle on fire......

I had never seen anything like this since I came to this world, something called a transparent cup, so I didn't seem to ask Waltz around.

Lucia then answered the question with her neck tilted.

"I don't know why... disappear?

"Yes, it will disappear. Because the ingredients that make the flames in the air are blocked by placing the jocks, right?

"Hmm... the ingredients that make fire here, are floating around?

"Yeah, right? The ingredient - it's called oxygen, but in order for the fire to burn, we need the oxygen that's in the air. But while the fire is burning, it uses a little bit of oxygen… If you cover the jock, the oxygen in the jock is gone, and the candle fire goes out."

"Hmmm...... I wonder if I figured it out somehow?

"Next time, I'll explain it right. So, to get back to it...... could Lucia burn this tree because I'm the demon (...) of the law (...) and I use the (...) of the (...) to work fine on the air to prevent oxygen from being supplied?

"What... but just now, you're not gonna burn, are you?

"Damn, it won't burn. It won't burn... but I'm sure something funny will happen, right?

…………

I still don't know what Waltz is talking about, with a strange look on his face, Lucia tilting her neck.

Looks like Waltz is ready in the meantime...

When she floated a great tree in the universe, she said to Lucia:

"Anytime you want, okay?

"... hey, sister?

"Hmm? Was there something you didn't know?

"Yeah. How come this tree... is floating?

"............... no? Lucia. Mind the details..."

"... ugh, yeah. I will......"

Starting this morning, Lucia nods with a subtle look, remembering that various things are floating around the universe.

And then she tried to wipe away all the questions, and she turned her hands toward Oki, who was floating in the universe.

"... well, let's go!

Dgowwwww!!

and began exercising unprecedented fire magic of great output.

As a result, as Waltz has seen, the trees will not burn...

The temperature seems to have only begun to rise.

Another thing I found out by that.

"(Lucia's fire magic doesn't make a flame as a phenomenon...)"

Apparently, Lucia's fire magic was a magic that fed heat to the object and raised the temperature.

Can you understand if I say ”warming magic” powerfully instead of ”burning magic” with fire?

To put it another way, the former is like broiling (abuzz) in a gas burner, and the latter - or Lucian magic - can be said to be like a microwave.

In the meantime.

Looks like Lucia noticed something, too.

"Oops... I'm sure you're using fire magic, but it doesn't get hot at all..."

With fire magic, Lucia, who is usually an operator, should also receive a small amount of hotline......

Today, at this moment, I could barely feel the heat of heat, even though I was sure I was supposed to be using fire magic.

Waltz, on the other hand, who was listening to it, seemed to know the answer and replied this way to Lucia's question.

"You know, because I'm creating a vacuum wall, right?

………… Shinku?

"Oh well... that was a jargon... Well, finally, right now, near this tree, there's no air at all. With the jock talk earlier, if you want to cut off oxygen, you just need to get rid of the air from near this tree in the first place, so"

"That... is it easy to do? Wind magic?"

"Hmm... maybe gravity-controlled magic?

"... Huh?

"... ma, anyway. Hot doesn't tell you that there's nothing there. For example, suppose there's a burning tree between your eyes? If you touch that, it's hot, isn't it? But if you didn't touch it, it wouldn't be hot, would it? This feels hot because heat is coming from burning trees through your hands. It's the same, and the air only transmits a little bit of heat, and if there's no air, it doesn't transmit heat at all (there's talk of far infrared or radiation, but if you start explaining it, it's going to be a big deal, so this time it won't be...)"

And, considering Lucia's prior knowledge (her tits), Waltz stopped explaining any further.

Anyway, she has to explain another phenomenon that's going to happen...

And before them, the great tree, which was spraying white smoke by being heated, began to dye its surface into black colour at a rapid rate.
