Combustion is an oxidation reaction in which an object reacts rapidly with oxygen while producing light and heat. The other day I told you that there is a gas called oxygen in the air. .... The other day I told you that the air contains a gas called oxygen.

Everyone listened with puzzled faces as he spoke one after another.

In other words, the most efficient way to produce light and heat at the same time in the magic of the first problem of today's lesson is to burn it, but this phenomenon requires better use of air than the sense of handling fire. The more oxygen you pour into a burning fire, the stronger the flame will be, but if you handle it improperly, the oxygen can cause an explosion even if there is nothing burning, making it very dangerous. If you plan to use fire magic in the future, you need to be cautious about safety. "Hey, Masaru?

"Hey, Masaru?

Adelina raises her hand and starts to speak, as if she has a question.

"Yes, Adelina. I've told you many times that I'm the teacher in class. When you're being taught by someone, whether they're a child or not, be respectful and take things seriously. .... "Yes, sir.

"Yes, sir. The oxygen explosion is the one that caused the temple room to collapse in the middle of the night not long ago with a tremendous noise?

Ugh... something I don't even want to remember. ....

"Yes, that's it. I'm not sure if you've heard of it or not. I almost died that time... you all saw it, right? I was blown away by the blast and my eardrums were ruptured... I might have died if Zelaphitis hadn't healed me when I escaped in the nick of time. Hahahahaha .... I'm sorry.

They were all in raptures.

I'm sure you'll agree with me. You should all be careful!

I spoke cheerfully, taking into account my own experiences, but he said, "I'll never touch fire magic. I don't understand. ....

I'm sure you'll be able to figure out the best way to use it. If you want to use fire magic, it's easier to use a flint or something similar to help you get started. Think of magic as firewood to be burned, and rely on tools rather than magic to ignite it. This is the elementary level of fire magic. If you want to cause an accident like the one I just told you about, you'll need to bring in an advanced mage from the kingdom and study for six months to a year or more, so don't worry about it. I'm sorry.

It's hard for even students who have received compulsory education in Japan to construct an image of oxygen because it's invisible, no matter how many times you tell them about it. This is especially true at the level of civilization and education in this world.

Look at this cup. If you know how it works, learn to use magic, and have the magic necessary for the phenomenon, you can do things like this! Here we go!

The water froze with a rumbling sound. Turn it over, tap it on the desk, and a chunk of ice comes out of the glass.

In the event that you have any kind of questions regarding where and how to use the internet, you can call us at the web site. It's a waste of time. It's just a waste of time.

If there are no questions, I will end the class. If not, then we are done. .... "Yes!

"Yes!

The one who raised her hand was Mei, the youngest student in the class.

I'm sure you'll be happy to know that I'm not the only one.

Ugh... that's the worst question I've ever received. ....

I'm not sure what to make of that. I'm sure you'll agree. That means you have to learn it the same way to learn it, but I can't tell you how to learn it, and it's not something you can learn. Simply put, it's difficult because it requires the help of God. I'm working hard with Zelaphitis to teach you a different form of healing magic. Is that okay? Mei?

"Hmm? You mean you'll try your best to use it?

Yes, that's correct. Good job, Mei. Yes, that's right.

What a cute little creature!

Since there are no more questions, we're done for today. Yes, stand up! Rei. Thank you.

「「「「「「 Thank you very much. 」」」」」」

They're pretty cute.
