The next day, continued his lecture on engineering magic.

"So far, we've only managed to make one true sphere," Rodriguez said.

Rodriguez says.

Well, you have to keep working on it. If I can make 10 balls at the same time in an instant, I'll be a full-fledged professional.

（Ten at the same time?　At the same time?)

（So, that's one person. ......?)

(Is it so advanced in the outside world? ......?)

Of course not, but the old man wanted to let the <> know a little bit about themselves.

That's why he instructed to do so.

How much do you know about materials?

Needless to say, in the field of magical engineering, it is not only the magic to be processed, but also the knowledge of the materials to be handled.

"I think I have a general understanding of the materials we are working with.

<

I see. Then, what is the composition of 64 light silver?

"Roku, roku......?"

What is the composition of 18-12 stainless steel?

Uh, uh, ......

What is the composition of 5-half nickel steel?

"......, I don't know."

You don't know?　They're all metals that my husband used to work with.

"......"

"Don't be so downhearted. If you didn't know, you'll learn.

"Will you teach me?"

Of course.

The old man thought to himself, "I guess I don't know much about materials after all.

Whether he would take it in later or leave it to <>, he wanted him to raise his level a little more so that he would at least have the ability to graduate from <> elementary level.

<

"Yes. It's an alloy of carbon steel and nickel.

What are its properties?

What are its properties?

The question is, what is nickel added to carbon steel for?

What's the ............?

You don't know about ......? You don't know much, do you?

"U......"

The addition of nickel improves low-temperature brittleness.

"Oh, so that's what it does!"

You know about low-temperature brittleness?

Yes!

As the name implies, 5?% nickel steel has 5.5% nickel added. In addition to this, 9% nickel steel is also used for applications at low temperatures.

"I understand."

"............"

While everyone was listening attentively, Lubark Bassi's heart was not at peace.

（d*mn it!　If everyone is listening, I won't be able to gain an advantage!)

) Lubark Bassi kept his ambition burning.

* * * * * * * * * * * * * *

At the same time on Horai Island, Jin and Erza were monitoring the education by < in real time.

"...... have you deteriorated ...... degenerated ...... so much?　You've deteriorated so much."

"Hmm."

<<>.

"You can barely ...... make one true sphere.

Jin felt a little or a lot disappointed that they can be called the top group of technology in a country with that .......

<

"Yes, that's fine."

And then we get down to the business of the rest of the day.

"So far the < who made <> remains a mystery, right?"

.

"Yes, that's fine. So, at ......, just for the sake of setting it up, we're going to say that you are the <<>>?"

<>.

"Yes."

"...... old man, can I ask you something?"

<>

"Well, the bird seller who sold pigeons to the mayor of Saich village, I was wondering if you might have a list of brainwashers.

Pigeons trained to return to the Principality of Jags.

All those to whom they are sold are those who send information to the Principality of Jags.

In other words, they are spies or brainwashed people.

"Yes, too bad."

If they are cooperative to some extent, it is possible to extract them by <>, but I suspect that they will probably refuse such magic.

In that case, we would have to force them to do so, but that was not the way Jin wanted to do it.

The reason for this was that he could not criticize the way the other ...... principality of Jags was doing things if it was a method similar to brainwashing.

"Now we have to wait and see what the Duke of Jagusu will do. ...... What are you going to do about it?"

> will respond.

But the old man answered that he could not simulate it because he did not know the personalities of all the <> yet.

"Well, if that's the case, I guess we have no choice."

With insufficient basic data, the results of the guesses are not reliable.

<

"...... Uh, a guy named Lubark Bassi?"

<<

<

"Hmm......... So you don't have much of a sense of camaraderie?"

<<

"...... that's rare."

<.

Of course, he knows that there are many engineers in the world who have such ambitions.

"Do you think it will be a wedge to be driven between the <> and the Duchy of Jags?"

<

The old man answered, and then began to think about his next move.
