Jin is servicing Meline, the chief maid golem.

First, he removes the exterior and checks the inside.

"Um, don't you need to check the <>?

Justa, the first engineer who witnessed the meeting, asks.

"Yes, there is no problem at all with this structure.

Since it is the one that Bina made in the past, that is, the Adriana style, Jin has no problem with it. It would be fine if it were in a different format, though: .......

"Stick to the basics. The effects of <> and <> are still there. The reason for the drop in tone is ...... ah, a maladjustment of the magic element converter (ether converter)."

"......"

Justa, the first technician, was confused, understanding only about half of what Jin was doing.

(What?　What?　What are you doing?　Uh, demolition is fine. But <> and <>?　What do you mean?)

<, 70% of the new technologies developed by Jin and his group had been discontinued.

The developed by Jin and the invented by Stealina were no exception, and had not been passed on until this time.

"Is Magical Muscle OK? ...... The material of the skeleton is bronze. Although it has been <, the original strength is low. ....... So this is what caused the distortion."

At least it should have been made of light silver, Jin thought to himself. And then,

"Mr. Justa, can I rebuild the skeleton with light silver?"

He confirmed.

"...... what?　Huh?　Uh, uh, yes, I think so."

Justa, who had been half-heartedly giving his permission, was quick to do so and then panicked a little.

(Oh no! ......!　Skeletal replacement?　That would take at least a day. In the meantime, wouldn't it be bad if Meline, the chief maid golem, didn't move ......?)

But before he can reiterate <>, Jin has disassembled Meline.

The handiwork was so brilliant that Justa could only exclaim, <>.

"Re......ko, get me some light silver."

"Yes, Brother Shin."

Reiko, whose name is Reko, followed the instruction of Jin, whose name is Shin, and took out an ingot of light silver from the materials cabinet.

The unit price of light silver (titanium, not aluminum in this world) had been reduced to 20 tol (about 200 yen) per kilogram by the refining magic tool made by Jin in the past. The price per kilogram of light silver (titanium, not aluminum in this world) was reduced to 20 tol per kilogram (about 200 yen) due to the magic tool of refining made by Jin.

It can be imagined that this meline was made before the price of light silver dropped to that level.

With the light silver, Jin used the <> without giving Jasta time to intervene, and made a skeleton member of the same size exactly the same.

<

Next, each dimension is grasped. Craftsmen are said to be able to sense differences in the order of microns with their fingertips.

Then, they use the magic of <> and shape the object by <>.

In other words, the original object and the object being made are compared with each other and modified, but in the case of Jin, a <>, dozens of checks are made almost instantly to duplicate the original object.

No wonder Justa can't believe his eyes.

"This is ......."

Jin's work speed is nothing short of amazing. In addition, Reiko has already separated the necessary amount of light silver by <>, so all Jin has to do is molding, adding to his speed.

"There we go."

"......"

The duplication of the skeleton was completed in about 5 minutes.

"Fu......"

It was not Jin who let out a sigh, but Justa. Justa was watching him with bated breath as he worked.

"Now, I'm going to apply adamantite coating to the joints and ........."

"What?

Justa is surprised to see Jin continuing his work without taking a breath. To Jin, it's a normal thing.

"Let's add one more line for the magic nerve wire.

One of the two wiring lines was completely disconnected at one point.

"Let's add some reinforcement.

Jin rearranged the muscles and rewired the nerve line at the same time. Reiko helped him, and it took about 3 minutes.

"Let's upgrade the shield case on the chest a little too.

The shield case is designed to protect the chest against <. The purity of mithril silver has been increased, and a two-layer structure has been adopted to enhance its effectiveness.

Then, I work on the ether converter and the mana driver.

"Oh, I knew it. I'm so concerned about efficiency that I don't have much tolerance for a high concentration of free magical elements (ether).

Muttering to himself, Jin takes the Magi Crystal in his hand.

"We could replace them, but ...... there's still room for more, so let's go with the twin type."

The twin type is a method of using two magical element converters (ether converters), one for low concentration and one for high concentration, in parallel, instead of using one magical element converter (ether converter) to handle from low to high concentration of free magical element (ether).

The switchable type is not used. In such a case, the operation around the boundary concentration is likely to be unstable.

"We should also add <> to deal with instantaneous power-up or temporary shortage of free magic element (ether)."

"......"

Justa is about to peel her white eyes off already.

"Let's make the exterior light silver and keep the color the same as before."

Thus, the maid golem chief, Meline, is now as good as new.

"Thank you, Mr. Shin. I feel much better now.

The rebooted Meline bowed to Jin.

"No, what? ...... Well, let's go ahead and fix the maintenance golem that you say is broken.

"That would be great. ...... this way."

Meline led Jin to a junkyard named ...... at the back of the workshop.

There, among several broken magical tools, lies a golem.

It is a golem that looks a little like Jin's .

（It seems that Bina modeled it after the craftsman (Smith).

At a glance, it is quite well made. At a quick glance, it is quite well made. It could be repaired to a very high degree.

Jin thought that if there were two or three of them, they would have been able to repair each other and survive.

But..,

"There were three of them, but two of them were given to the royal family of the time," Meline explained.

Meline explained.

"It was about 200 years ago. The Royal Magi Craftsmen were no longer able to cope with the many malfunctions of the city's magical tools and golems, and so the Royal Magi Craftsmen alone were unable to repair them, so our family also provided golems for repair.

"I didn't know that was possible."

Jin instructs Reiko to bring out the golem for repair.

"And it was never returned.

After that, there was a series of incidents such as the emergence of Malquitas and the rise of the , and those two golems were destroyed as well.

"I see."

Jin laid the repair golem on the workbench as he listened to Meline's story.

"Hmmm......... how was it destroyed?"

No wonder Jin tilted his head. The repair golem's head was crushed and its right arm was missing from the shoulder. Its right leg was crushed from the knee down.

"There was a band of bandits ...... who attacked this place 86 years ago, a band of mercenaries, and they had several battle golems with them, so there was a fierce battle, and the repair golem was on the battlefield at that time, and the bandits were able to repair the golem. ......"

(hmmm repair man).

(Well, ...... repair personnel are easy targets, so why couldn't they have been left in the rear?)

) Jin thought, but he kept his mouth shut, not knowing what was going on at that time. Instead, he moved his hands.

"It's for repair, so the material is relatively soft bronze or ...... brass for the fingertips."

Jin thought it was probably to avoid damaging the material.

"Take off the light silver, please.

"Yes."

The use of bronze for the skeleton seems excessive, but then again, this was made at a time when light silver was expensive. Jin thought it was probably a matter of cost.

"Let's repair this one too, using a duplicating process."

While Justa was in a state of shock, Jin proceeded with the repairs quickly.
