"I see, the ratio makes such a difference!"

"Jin, that's amazing!"

First, the magical muscle made with a near-optimal ratio was compared with the conventional one. Jin showed that it was about 1.5 times stronger.

"Next is the shape.

Metallic materials shrink and expand due to changes in interatomic distance and crystal structure, respectively.

Expansion due to heat is the former, and expansion due to martensite formed by heat treatment (quenching) of steel is the latter.

In the case of Magical Muscle, the interatomic distance is changed.

The speed of this change is very fast, but the disadvantage is that the amount of change is small. To compensate for this, the distance between the fulcrum and the point of force is kept extremely close, as in the principle of leverage.

Naturally, the distance between the fulcrum and the point of action is far apart for leverage, making it difficult to exert force.

Jin points this out,

"By lengthening the muscles, the rate of change is the same, but the amount of change can be increased.

He explained.

"That's logical, but how do you do it?"

"By twisting thin strands of wire and binding them together.

His words came as a bolt from the blue to those who heard them,

"Oh my God!"

"......It certainly makes sense. ......"

"How could no one have noticed such a simple thing ......?"

Someone muttered.

Yes, these things that Jin explained are the things that are explained at the end of the elementary level in the former engineering magic course in .

If you want to increase the performance, you can add not only mithril silver, but also small amounts of special elements, or <>.

In the latter case, the interatomic distance in the longitudinal direction is increased, albeit by about 10 percent. The amount of shrinkage increases accordingly.

This is an intermediate level subject, and Hitoshi does not intend to explain it in detail.

Even so, it is significant that the two processes performed by Jin were able to obtain a little more than twice the performance of the previous one.

"Jin, you are amazing!

"You've made my research much more advanced!

The researchers in general praised Jin.

The general researchers all praised Jin. ......, but only Carrion, the head of the laboratory, stared at Jin with a complicated expression on his face.

* * * *

"Well, you are amazing. I heard that you don't have part of your memory?"

"That's hard work. But you must have been a very good engineer to have achieved so much so quickly.

That night was a welcome party for Jin.

However, no alcohol was served since we had to work from 7:00 p.m.

"Was the golem you are using now developed in your laboratory?"

Jin asked, a little curious.

"No, there are such golems, but most of them are imported for combat use. Our dream is to one day create a golem that surpasses the imported ones by ourselves.

"...... sounds good."

Regardless of the purpose or motive, Jin could understand the enthusiasm with which they were betting on the development of the Golem.

"Most of the golems we are analyzing this time were taken from the Duchy of Norway in the last battle. That country seems to be relying on imports from the east instead of development."

"I didn't know there were countries like that."

Since this was a casual banquet, Jin was able to gather a lot of information.

According to the information,

There is a country in the east that has a high level of golem technology.

Skirmishes occur about once every three months.

Skirmishes are fought between 50 to 100 golems.

The Duchy of Jagus is the strongest of the three skirmishing nations, but not strong enough to take on the other two at the same time.

The Duchy of Jagus is rich in metal resources.

The Duchy of Norway is rich in metal resources.

I found out these facts.

The researchers did not know why the three duchies were skirmishing with each other.

(I should know, but I shouldn't know, right?　...... to avoid giving them unnecessary information?)

Jin was thinking about that.

(And if he could meet someone named <>, there must be some progress in ......)

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

At 19:00, they returned to the laboratory.

"You're late, guys."

Carrion, who was not at the welcome party, said irritably.

"(I don't like it because of your immediate success.)"

A colleague standing next to Jin overheard him softly.

(......I'm a little too conspicuous, aren't I?　But I have a purpose too. ......)

It's true that there are bosses who are averse to good subordinates and bitter about their subordinates taking credit for their work, Jin thought to himself.

"Now, the remaining items to be analyzed are the control core (......)."

Raig Armor looked around at his team members.

"The control core of this golem was destroyed and there was nothing we could do about it."

Half confirmation, half explanation to Jin.

"I see... ...... that's unfortunate."

Jin was unusually cautious, saying that it would be a bad idea to say that he could read information from the fragments, even if it was only a fragment of information.

In the first place, this technique belongs to the advanced level of the engineering magic courses in .

"The control cores removed from other golems are being analyzed in another lab.

We'll let you know when we have the results," Rig Armor explained.

"So let's start analyzing the next golem."

Raigh Armor turned to the lined up Golems.

"Well, which one should we choose?

"Well, what about this one, Raig?"

Cu Fenet, the first one in the lab, pointed at one of the golems. The exterior had been removed halfway, exposing the interior.

"Oh, that's it. That's a good one."

(This is ......)

It is a burly golem with a clearly combat-oriented appearance. Jin does not recognize its structure. This means that it is not of Adriana's lineage.

So Jin was curious about it.

"Its skeleton has an interesting structure," he said.

"Yes, indeed.

The forearm was shown. The forearm should be composed of the radius and ulna in a human.

The same is true of the automata made by Jin, or rather Adriana.

This is because the idea is that it is important to imitate the skeletal structure of a human being in order to make them behave like humans.

The basics are the same for the golem. It is just simplified in some parts.

As for the forearms, the Adriana system uses the radius and ulna.

This allows a motion of the wrist.

In order to twist the wrist without using the radius and ulna, it is necessary to rotate the forearm bone or wrist part around the axis.

But that structure would lead to a reduction in strength.

"It's certainly an interesting structure, but ......."

Jin trailed off.

The golem in front of him had a structure in which the wrist part rotated.
