"This <> uses an ether converter and a mana driver.

The fact that the other golems are not like that, but rather use mana tank technology, shows that the Lance is of a different construction.

"That doesn't make it any stronger. ......"

It is also evident from the fact that the lance was destroyed by a lower-ranked attack, although it could not attack on its own.

Combat and defensive abilities do not necessarily correspond to the structure and materials.

Jin was repairing the lance while saying this to Erza,

"The one made by ...... Jin's brother is different.

Elsa's hand was interrupted by Reiko's nodding.

"Well, the structure is an endoskeleton, similar to the previous generation's form. However, there is a little too much waste.

"Jin, what do you mean by 'wasteful'?"

Jin pointed at Erza's question and explained.

"Erza would understand. "Elsa would understand. Like the ribs."

"Oh, really."

Such a structure is effective for humans who breathe through their lungs, but it has the disadvantage of reducing the strength of an automata.

"But..."

But what?

"I was thinking that the creator of this Lance may have been trying to create an automaton that is as close to a as possible."

"Somehow, I understand."

Erza nodded in agreement with Jin's line.

"But, you know, human beings are not necessarily a complete life form.

"What do you mean?"

"You see, it's good that we can use our hands dexterously because we walked upright. It's also good that our brains have developed because of it, but we've also had to deal with disadvantages like back pain, a dropsy stomach, and difficult childbirth."

"...... I see. That makes sense."

All of these symptoms are rarely seen in quadrupedal mammals.

Seeing the same number of spinal columns as humans and the same pelvis shape, Jin and Erza felt the creator's care.

When Jin was in modern Japan, he was a when it came to models, preferring to move and play with ships, cars, and tanks.

On the other hand, it is true that there are people who are concerned with how precisely to reproduce the real thing.

Jin imagined that the creator of this Lance must have had such a mindset.

"He must have been concerned about the finished product, with performance being of secondary importance.

Thinking of this, Jin was even more curious about what kind of person he was.

"The muscles are arranged so that they are as similar as possible to human muscles.

And the internal organs were made to look more like a human than a golem.

"Don't get hung up on it. ...... I can't overlook the fact that it's going to lose performance because of it."

Jin is impressed, but not sympathetic.

"I still think it's good. It is more complete than any other Golem automata I have ever seen.

"Except your father, of course?"

"That's more than Elena, isn't it?"

Reiko and Elsa asked almost simultaneously.

"Yes. I don't know if I can say that myself. I'm better than Elena.

Jin analyzed that although she might be as good as Elena in appearance, she might have more power than Elena, partly because of the difference between the adult male form and the girl form.

"That's because they use < for muscle tissue."

This is the reason.

If there are <, they would be located in the northern part of the Kruger Mountains. The fact that they can go that far is proof of their extraordinary technology.

"Anyway, let's finish the repairs.

Jin is repairing the ripped off arms and bent legs as he goes.

"However, amorphous material feels strange.

Jin comments on the engineering-magical feel of a material he is handling for the first time.

"Is it?"

"Yes. It feels viscous, or muddy, or something. Do you want to try ...... for a bit?"

"Yes.

I decided to let Erza, who seemed to be interested, try to correct the crooked legs.

"<>......Yes, I can see that."

"Right?"

It's not that it's hard to deform, it's just that it has a unique when it deforms.

"I don't intend to use it, though."

Saying this, Jin repaired all the remaining parts.

"I guess that's it."

"Brother Jin, the magic machine in your body has changed, did you understand it all?

Yes, I did.

"As expected of your father!"

Reiko praises him with open arms, and Erza looks at him with surprise.

"The lungs are the ether converters. The heart is the mana driver. The liver is an emergency mana tank.

I can see that.

The stomach and intestines can simulate eating.

Reiko and other automata in Horai Island also have this function.

"Spleen is a magical tool for . The kidneys are magic tools for ."

It is true that they couldn't have assigned all of them to the same functions as humans, but this is still quite a feat.

"Then, the control core is the head?

"Yes. As far as I'm concerned, it is easily damaged.

In addition, there is the problem of distance differences in the transmission of commands to the limbs.

The arrival time of signals from the arm to the leg is slightly different.

This is a subtle issue that only becomes a problem when the speed is increased to the limit.

"But it might be a good way to quickly capture and process visual information," Elsa commented.

Elsa commented.

"Yes, that's true. There are advantages and disadvantages, of course.

However, as Jin heard stories of people in extreme situations where they could see but not move their bodies, he wanted to emphasize the importance of <.

is Jin's motto.

Naturally, there are exceptions. Jin is not so narrow-minded or inflexible that he does not accept such exceptions.

"Well, that's it."

The repairs are almost completed as before.

If it were a golem or an automata of his own making or of someone close to him, Jin would have taken this opportunity to enhance it, but this time he seems to have refrained from doing so.

Rather, it could be said that he was unsure of the relationship between <> and himself.

"<>"

<> opens his eyes.

"Oh, it's really fixed. And it seems to be a little better than before. You were right, Reiko.

Jin was secretly surprised that Lance pronounced like a native.

That meant that the performance of the <, which was the brain, was quite good.

"Thank you, Jin-dono."

Lance bowed his head toward Jin.

"No, that's fine. So ...... no, Reiko, you go ahead and ask him."

"Yes, father. ...... Mr. Lance, will you take us to the place where you were made?"

"If that's what you want."

After all, Lance had agreed so readily.

Then, when the sun comes up, I'll ask you to come.

Yes, sir.

It was still 2:00 a.m. local time.

Jin suggested that Elsa take a nap.

But I have to check on Edgar.

I'll take care of that. You need to get some sleep, or you'll get sick.

With that being said, Elsa could no longer refuse to sleep.

"I'll do it then.

Erza then took a nap in .

While she was napping, Jin helped Edgar with his maintenance work.
