It’s been a while since the exchange program ended.

Winter was approaching, and more and more students were wearing thick clothes.

Incidentally, the school had uniforms, one for summer and one for winter.

At that time of the year, most of the students wore the winter uniform.

It wasn’t so cold in the classroom, so I took off my cloak and went to class.

“Good morning, everyone.”

The person standing at the podium was Maurice.

He’s the deputy homeroom teacher who took care of Class A when Chris-sensei wasn’t here or when he’s fighting off demons.

He was an intellectual with glasses and gave the impression of being serious.

“Today we’re going to talk about how to use magic stones. Magical stones were usually used as a source of energy.”

Maurice-sensei took out a magic stone from his pocket.

“This is an unprocessed magic stone, which is indispensable for the development of magic tools. The magic stones used for magic tools cannot be used in this state. They must be melted to a liquid state or crushed to powder before they can be used. Today’s class is not about magic tools, so I’ll skip this part. If anyone wants to ask, please come and ask after class.”

The class on magic tools was an elective class available in the middle school.

“I’ll explain how to extract the magic power from the magic stone. The magic stone is useful as a reserve magic power for emergencies. In order to extract energy from a magic stone, you need to put your own magic power into it.”

It was very important to have a magic stone in case you run out of magic power.

Magic was everything to a wizard.

In fact, if you’re in a tight spot and you lose your magic power, it was bad.

You couldn’t do anything.

The most famous wizards had several magic stones that contained their magic power.

“You can’t put magic power into something like that. How can you put magic power into something like that?”

One of the students asked.

“That’s right. A magic stone contains magic power from the beginning. Pouring your own magic power into it is like pouring liquid into a container that is full of water. In addition, when you pour magic power into a magic stone, you have to do it all at once. Incidentally, the best ratio of magic power contained in the magic stone to the person’s magic power is 2 to 8. If the ratio is higher or lower than this, the energy efficiency of the extraction will decrease.”

Maurice-sensei continued.

“The magic stone is so pure that there is very little room to put magic power into it. If you are a skilled magician, you can only put in about one tenth of your own magic power.”

“Wow. It’s not as easy as you might think to use a magic stone.”

The boy’s shoulders slumped with disappointment.

“It is useful if you learn how to use it properly. If you put magic power into it, you can finally create your own magic stone. For example, this one.”

Maurice-sensei took out a green magic stone from his pocket.

“The color of the stone will change when it is filled with the person’s magical power. The color of the magic stone depends on the magical properties of the person, so the magic stone can be completely unique in the world. Today, we prepared a small magic stone. Let’s use it to make your own magic stone.”

I looked at the magic stone that was handed to me.

The size was quite small, less than a centimeter in diameter.

“The trick to putting magic power into it is to press it in tightly. Now, please begin.”

I put the magic power into the magic stone, but the magic power didn’t penetrate very far.

I felt like the magic stone was not accepting the magic power like oil repeling water.

As Maurice-sensei had said, I strengthened the magic power and tried to force it in.

Then, I put the magic power into it for a while, but I couldn’t get any response.

The color barely changed, and what had been clear only became slightly cloudy.

That was difficult.

After that, I tried several times with other magic stones, but the results were not much different.

“I’m sure you’ve just done it, but it’s difficult to put magic power into a magic stone. This requires experience, so please keep up the good work. That’s it for today’s class. By the way, the final exam starts next week, but we won’t be covering the material we covered today.”

As Maurice said, this was the time of year for the final exam.

The first test was between the high orc battle and the social event, and I got a good grade in the written test, using my knowledge from my previous life, and almost a perfect score in the practical test.

I was sure I’ll get a high score on the final exam as well.

This was what I call a reincarnation cheat!

Wa-ha-ha.

Well, if you think you can get away with that, you’re going to get your feet stuck in the sand.
