"Combustion is an oxidative reaction in which objects react rapidly with oxygen while producing light and heat. There's a gas called oxygen in the air that I told you about the other day...

Everyone listens with their faces in pokernels to what is spoken one after the other.

"I mean, the most efficient way to get light and heat out at the same time with the magic of today's first problem in class is to burn it, but that phenomenon needs to use the air better than it feels to handle fire. If you pour more oxygen into a burning fire, it becomes a stronger flame, but if you handle it, oxygen is very dangerous because it causes an explosion even without combustion. In the future, if you intend to use magic about flames, you will need to be cautious in terms of safety.

"Hey, Masal?

Do you have a question? Adelina talks with her hands up.

"Yes, Adelina. You told me many times during class you were a teacher, didn't you? When you teach people things, be they children, but be respectful and sincere about things...

"Yes, Doctor. Did the oxygen explode a little while ago at midnight when the temple room sounded awesome and collapsed?

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

"Yes, that's it. I took a lecture from Master Zeraffitis and tried it, but it's like that. I was dying for real then... you all saw that, right? That sturdy white stone shattered and scattered fragments stabbed everywhere, and the blast blew my eardrum to tear... and if Master Zelafitis, who withdrew with a single hair, hadn't healed me, I might have died. Hahahaha...

Everyone is utterly silent.

"Anyway, my teacher also thought that magic must be used safely based on location and circumstances. Just so you're all careful!

I spoke brightly based on my experiences and they said, "I'll never get my hands on the magic of flames," etc. I can't solve it...

"Well, if you want to use the magic of a series of fires, it's basically easy to use if you use a firestone or something to assist you with the first cut. Considering magic as firewood to be the subject of burning, fire itself relies on tools rather than magic. This will be the magical elementary of fire. If you're going to have an accident like the one we just talked about, don't worry about it because you're going to need six months to over a year of study with a senior demon mentor at the Kingdom.

It will be difficult to construct an image even for students with compulsory Japanese education because it is generally invisible no matter how many times the oxygen is taught by mouth. The level of civilization and education in this world is even worse.

"Please take note of this cup. Inside is water… if you know how it works properly, learn how to operate magic, and if you have the magic necessary for the phenomenon… this is possible! Whoops!

The water freezes with freshness and sound. Turn it over, tap the trick on the desk, and ice solidification comes out of the cup.

"" "" "" Whoa!

There is cheer in the room, but this magic is actually a big magic of defects… it consumes about 40-50 glasses of magic. The country's best demon teacher has about 200 glasses of magic power, so when the efficiency of magic is reduced, the country's best demon teacher makes three glasses of ice. I feel like I'm superior here for nothing.

"So, I'm going to finish today's class. Do you guys have any questions, etc.? If it doesn't seem like it, I'll be done...

"Yes!"

It was Mae, the youngest in the class, who raised his hand.

"How can I cure a wound like Dr. Ooi-chan's magic all the time!

Ugh... you've got the worst question ever...

"I want you all to be able to use your healing magic because it is very efficient and effective as a magic..." Your healing magic deviates from this world with something special, "according to Master Zelafitis. I mean, I can't remember it unless I remember it the same way, but I can't even tell you how to remember it, and it's not something you can all remember. Simply put, it's difficult because it's a way of needing God's help. We consider ourselves dear Zerafitis so diligently that we can teach everyone different forms of healing magic. Is this good? May?"

"Cancer? You mean hang in there so you can use it?

"Yes, you're right. May, well done.

May, who looks happier... what a lovely creature!?

"Yes, that's it for today because I don't seem to have any of your questions. Yes, stand up! Salute."

"" "" "" "Thank you.

They are quite adorable students.
