"Well, things have been going well so far..."

Jin said to himself on the island of Horai.

had predicted, wasn't it?

"Yes. The question is after tomorrow.

.

That's what Jin thinks.

So far, I haven't had a chance to touch any important equipment yet.

"I guess I should rest first."

and are located on opposite sides of the island, so the day and night are completely reversed.

< and his friends are active without distinction between day and night, they seem to have a sense of time, and Jin's alter ego (doppelganger) gets a rest time at .

Therefore, Jin takes a nap to prepare for the night.

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

"Well, it's about time."

Oh, Jin-dono, please!

Jin's doppelganger rises from the bed, and at about the same time, appears on the bed.

Today, it's the golems that will be serviced.

"The from before?"

"That's part of it. For combat, security, and maintenance.

Maintenance?　You mean maintenance personnel?

Yes, that's right.

I see. ......

Jin felt a little disappointed. If the maintenance staff was restored, there was a good chance that they would be in charge of maintaining the brains.

Still, Jin had no choice but to refuse, and he also had the advantage of being able to analyze the Golem.

This way!

Guided by hernte, Jin's doppelganger stepped into the Golem's hangar.

"Oh ......!"

He exclaims. There, lined up in a row, were about 100 Golems, including the familiar .

I want this done as soon as possible. The warehouse is in the next room. I don't think there's anything missing.

"Okay."

The thing I'm most concerned about is whether or not the golems here are being eroded by the <.

We will find out if it is.

Jin's doppelganger begins its maintenance together with Reiko.

Oh, you are fast!

It is enough if you can do about 20% of what Jin can do.

Most of the golems were only <.

"<>"

The oxide film is removed by the engineering magic of reduction. For sliding parts,

"<>"

and surface treatment was used to reduce frictional resistance.

Muscle tissue is a synthetic material.

This material is unknown to Jin. <.

He tells this to who is watching him,

He replied, "The is more powerful than I am.

He replied, "I have been in this situation before," he said.

"What about the automata that were dispatched to the Shoro Kingdom before?"

As for this,

"They are in the room next to the one we put there. I am going to ask you to maintain it after this.

I'm going to ask them to maintain it afterwards.

"Okay."

Jin's doppelganger decided to concentrate on his work, not to ask any unnecessary questions until he had done all the maintenance and analysis.

As a result, the maintenance of the 100 golems took half a day, and the remaining half a day was used for the maintenance of the automata.

Jin, the main body of the Golem, operated the doppelg?nger only about one-fifth of the time, while the rest was done by the old man.

Still, there were many things to be gained.

First of all, the Golem automata here had not been eroded.

"Well, that's a relief, first of all.

remains.

Secondly, I secretly attached a set of monitoring devices, that is, a and a , to the maintenance golem.

This way, even if Jin could not be entrusted with the maintenance of important equipment, he could know the contents of the equipment.

Third, we were able to learn about the golem technology of the <> method.

Although Jin seemed to be more advanced in this respect, it was a good thing to know that they were making muscles and skin of automata from synthetic materials, and to be able to identify the materials used for them.

"Let's call it Magi Plastic."

Since there was no name for it, Jin named it himself.

Magi Plastic is a macromolecule, just like plastic on Earth. The only difference is that the atoms contained in it are magical isotopes.

As expected, Jin did not know the chemical structural formula of plastics.

However, he had learned ethylene C2H4 and polyethylene made from it in high school chemistry, so he was able to understand only <>.

But there was a problem.

"But where are they going to get the magical isotopes (Magi isotope) carbon C and hydrogen H?

Procuring the raw materials was a mystery.

<

The old man advised me.

"Yes, that's it!

Magi resin is, in other words, pine resin with magic power. The chemical structure is almost the same.

However, since Jin did not know the chemical structural formula of pine resin, he could only determine the ratio of carbon C, oxygen O, and hydrogen H contained in it.

However, once we know that much, we can carbon C and hydrogen H, which are magical isotopes.

At the same time as extraction, it is now possible to produce ethylene gas by .

This was Jin's original engineering magic, an application of and .

"I'm almost ready to make polyethylene from ethylene. ......"

>.

The old man rebuked Jin, who was getting very angry.

"That's right. Let's take a rest for now.

<

Yes. I can maintain golems, live puppets, and low-level facilities with no problem.

Whether you want me to maintain the intermediate level facilities or not?

I think I can handle it.

Yes, I think so. Even if they know a little bit about our secrets, as long as we don't let them leave.
