A special lecture by Sage Luano began.

''First, let's talk about the expansion of the magic furnace.

What is a magic furnace?

　Rifa asks the headmaster a question.

　It's a word I don't know either.

It's the organ through which humans create magic power inside their bodies. However, even though it's an organ, unlike the magic stone that can be obtained by dismantling a demon, the human magic furnace is invisible to the eye.

　When you defeat a demon and dismantle it, something like a jewel will be taken from its body.

　This is a demon stone.

　The magical power of the attribute of the monster dwells in the demon stone, and it becomes the material for making tools.

　There are tools that can be used in battles and in daily life.

　Magic tools are what make our lives convenient and rich, and the source of those tools is the magic stone.


　Magic stones cannot be taken from humans.

　But since we can use magic, I knew that we were creating magic power somewhere in our bodies.

　It's called a magic furnace.

How do you know it's there if you can't see it?

　Luke asked.

I call it the power to see other people and their magic. The power of my magical vision is strengthened when a wise person uses it. The more you use it, the more information it gives you.

　It is said that if you continue to use your demon vision, you will be able to see not only the amount of magic of others, but also the color of their magic.

　From the color of the magic, you can tell what kind of magic the person is good at, for example.

　In addition, it is also possible to read a person's psychological state from the wavelength of magic.

''When you train that magic vision, can you see the magic furnace?''

Yes, that's right. I know that there is an organ near the human heart that generates magical power. But I have been using magic vision for more than ten years, and even if I were to announce the existence of my latest discovery, no one can prove it.

　If it was an organ that even Sage Luano had only recently noticed its existence, it was understandable that it was not currently mentioned in any literature.

''This magic furnace, I found out that the bigger it is, the faster it recovers its magic power. And the magic furnace can be made bigger with training.

What kind of training is that?
I want to know!

　Luna and Luca leaned forward.

　Luna has the least amount of magic power in her class.

　Although Luca has a large amount of magic power, his specialty, Resurrection (resurrection magic), consumes a lot of magic power and causes him to run out of magic power quickly.

　Both of them have to deal with the amount of magic and the speed of magic recovery.

''It's a matter of using up all the magic power and recovering it repeatedly.

　What?　That's it?

''Um, Headmaster-sensei. I'm always using up my magic power, but I don't feel like my recovery rate is going too fast.

　I've seen Luca using Resurrection before, and I've seen him get stuck due to exhaustion on several occasions.

　However, as he noticed, I don't think Luca's magic power recovery speed changed much before and after that.

''Luca, when you've used up all your magic power, are you conscious?''

Oh, yes.

This is not the way. You must drain your magic until you pass out.

What?

　What, really?

I think everyone knows that when your magic power is reduced to zero, your strength is depleted. And if you deplete your strength too much, you'll die.

　It's common sense in this world.

　That's why you need to use magic carefully so that it doesn't reach zero power and strength.

It's not well known that if you use magic after the maximum 10 percent of your body's energy has been used, the magic won't work and the person will be forced to faint.

Is that so?
Really? I didn't know.

　I didn't know that either.

　Well, there's no way to know because the magic power doesn't decrease.

''By using your magic power until you lose your mind, and then recovering it, the magic furnace will grow a little larger. Well, it's going to be quite a painful exercise, so it's up to you guys to decide if you want to do it or not.

　The headmaster promised me that if we were going to do this training, he would support us well.

　He said that if you don't do this in a proper environment, there's a risk.

　However, as I can't reduce my magic power, this story wasn't very useful to me.

　But the wise man, Luano, was also thinking about me.

Don't worry, Harut. I can give you some useful information. Do you know about the magic square?

'The Magical Road, sir?　I don't know.

''It's a pathway for the magic created by the magic furnace to be released out of the body. The thicker this is, the faster the magic can be activated.

Oh!

　Oh yeah, I didn't know that.

　A long time ago, when I realized the effects of the evil god's curse, I thought about speeding up the activation of my magic in order to become stronger.

　After some trial and error, I learned the art of speeding up the activation of magic by releasing magic power, which is usually only released from the palms of my hands, from all over my body.

　But as the sage Luano says, if I make my magic transmission path thicker, my magic might become faster and more powerful.

　I want to know how to do that!

How can I make the demon channel thicker?

You must take the magic you released from your body and force it back into your body.

..........

　I mean, how can you do that?

　The elves can collect magic power from space, but instead of taking it into their bodies, they wear it on their bodies and make it into attacking magic.

　In other words, it was common knowledge that magic power once taken out of the body could not be collected and had to be spread out in space.


''Putting back as much magic power as possible in large quantities at once would be more effective. It's like using magic power to forcefully push out the magic transmission path.''

When releasing magic power, can't I just accumulate it and release it all at once?

The magic road is essentially a one-way street. It's designed to eject smoothly, so it wouldn't do much good to eject them all at once.

　It is said that the magic transmission channel has the function of preventing other people's magic power from entering the body and causing magic sickness.

　And although it is possible to manipulate the magic power once it is emitted outside the body, its quality changes when it is mixed with a small amount of magic power that exists in space.

　The body does not accept the magic power that has been released from the body and changed its quality as a foreign substance.

　The wise man Luano says that the magic path is widened by forcing the unacceptable magic power through the body.

Incidentally, training to widen the magic transmission channel is ten times harder than training to expand a magic furnace.

　Even though that's what the wise Luano threatened me with, I was going to train.

　My goal is to be able to protect Tina from any threat.

　Recently, Rifa was added to my list of targets to protect.

　And to beat the evil gods, one of the gods of this world.

　It might be futile, but I was determined to do whatever I could to become stronger.

''I'll do that training,''

　I declared, turning to Luano the Wise.
