Jin D. began to explain slowly.

"I'm sure you know that there are individual differences in magical patterns."

"Well," said Jin D., "in the advanced course of magical theory, we analyze such magic patterns.

"In the advanced level of magic theory, we analyze such magic patterns, and the distribution of their frequencies is called the ."

"I see."

This is what is taught in the course at <>.

From here, Elsa D. takes over the explanation.

"I say that the peaky spectrum is more suitable for offensive magic.

The spectrum corresponds to the attributes, with the lowest frequency being earth, water, wind, fire, light, and darkness.

The spectrum can be further subdivided. For the water attribute, the lowest frequencies are ice, water, and steam. Light is similarly divided into infrared, visible light, ultraviolet, and electromagnetic waves .......

If there is a peak in the spectrum corresponding to each attribute, it means that the magician is good at the magic of that attribute.

Incidentally, it was analyzed that engineering magic requires a high level of all spectra, while healing magic does not have to be high, but flat characteristics are desirable.

However, this kind of research is still in the developmental stage, and depending on how future research is conducted, the current theory may be overturned.

"So, sir."

The explanation returns to Jin D.

"Najas-san's magic pattern and spectrum seem to be suited for healing.

How do you know that?

"How do you know that? I'm good at healing magic!

Yonas Tigrina and Najas Khan asked back.

"How can you say that? ...... Oh, um, this Reiko can detect such things."

Jin quickly explained that it would be more convincing to say that Reiko, an automata, could do it than to say that he could do it.

It is not a lie that Reiko can do it. Both Jin and Elsa can detect.

"I see... I see... Miss Reiko can do it..."

"So, I think it would be a good idea to learn healing magic from a proper master, if possible.

Jin added.

"Let's think positively.

Now is not the time, Jonas said.

"Once again, welcome. It is an honor to have the renowned third generation of magecraft masters visit us.

No, not even his predecessor.

No, no, you are too modest. I have heard of your visits to neighboring countries."

Jonas said he had heard that the air race in the Kingdom of Klein had been a great success.

"I hope we will be able to hold such a race in our country someday," he said.

"I hope we will have it in our country someday," he said. "Competitions are not only a way to improve technology, but also for entertainment.

Jin D. suggested that public gambling in such a place might be a good way to get rid of black market gambling.

"Oh, I see."

Black-market gambling, by its very nature, is highly profitable for the operator. In other words, there is little return to the participants.

If public gambling that pays legitimate dividends were to take place, it might be possible to eradicate black-market gambling. ......

Although it is necessary to be careful not to cause gambling addiction, etc.

A total ban on gambling will only make people go underground. .......

Yonas Tigrina and Najas Khan were impressed when Jin explained this to them.

"I see, you are very well educated, Jin-dono."

"No, no, I'm just following what you say.

While they were talking like this, there was a distinct knock at the door.

"Yes, it's time for you to come in.

Najas opened the door to find one of the king's secretaries standing there.

* * * * * * * * * *

Five minutes later, Jin D., Elsa D., Reiko, Hope, and the others were ushered into the King's office.

"Welcome, Sir Jin Nidor, the third generation of Magecraft Meister. I am Caroline de Lafayette, King of the Kingdom of Franz.

The King of Franz was a queen.

She was young, just a little over 30 years old.

Above all, she looked a little like Catherine, whom Jin and his friends had met in the past. She must be of the same Lafayette blood.

Through Jin D's vision, Jin had such a thought in his mind.

"...... Our country was not so much influenced by the <>. This is because we were originally an agricultural country and our technology was not advanced, which is a disgraceful reason.

The queen began.

"By coincidence, I heard that you played a role or two in solving the case in the town of Loron, and I wanted to thank you and ask if you could give us some hints for the development of our country."

Next, a middle-aged man standing beside him spoke up.

I am the Prime Minister, Joachims de Droe. First of all, I would like to thank you for your assistance the other day. And we offer you treatment as an and the right of free access to the royal castle.

As a man who has received similar privileges from other countries, he can now behave in the same way here in the Kingdom of Franz.

"I humbly accept."

"Mm, superimposed."

The queen opened her mouth again.

"So, how do you feel about it, Mr. Jin?"

"Your Majesty, you're being too hasty."

"Ummm..."

The queen is hoping to get some advice from Jin, but is warned by the Prime Minister about her haste.

"Well, first of all, why don't we improve the and encourage the use of magic tools?

Before coming here, I had seen many mana stands in various places, but most of them were malfunctioning, except for the one that Jin had supposedly created.

Jin first said what he had noticed.

"I see, if the number of magic tools used increases, the demand will also increase and the economy will be revitalized.

The Prime Minister made a note of this happily.

"And ...... well, since there were unexpectedly many golem cars, it would be a good idea to hold a car race.

"A race, you say? ......"

The Prime Minister is not very enthusiastic about this idea.

Is there a problem?

Yes, in fact, about fifteen years ago, we held a car race at the military parade ground, but it didn't go very well at all.

"Hmm. ...... By the way, how did you do it?"

"That's right. ......"

The Prime Minister began to speak.

"We built an oval course on the training ground and had people race laps around it. The number of cars running is three at a time, repeated five times."

"......"

"The spectators are allowed to watch the race in a special area outside the parade ground."

It was a very bad example.

"I think there is a problem with the way they are doing it. I don't think that would be interesting to watch. ......"

Jin D. points out points that need to be improved.

First of all, increase the number of cars in a race.

He explained that this would make it harder to predict which car would win, and would also make the audience more enthusiastic and the competition more intense.

"I see, that's true.

"Then, the spectators can have their own seats ...... so that they can look down on the course from a slightly elevated position. Then we will charge an admission fee, which should be cheap."

<

"We can also set up a so that those who are far away can also enjoy the race.

Jin D concluded, "It will cost money at first, but we should be able to recoup it by collecting admission fees and acting as a betting agent.
