The next day, Jin was very busy from the morning.

"Jin-sama, His Highness Prince Ernest wants to see you.

As soon as breakfast was finished, Jin received a call from the prince and went to the inner palace. There was Prince Ernest the Third with Lotte.

"Ah, Jin, you'd better fix right away!

Prince Ernest the 3rd says. Jin smiled and agreed, knowing that although he was being selfish like a royal, he cared for that he had made.

"If possible, I'd like it if you could make it stronger than before.

Jin replied to the prince who said so,

"Tougher?　Not to make me stronger?

Jin asked back. The prince replied,

"Yes, it must be better to make it strong, but I don't want it to be broken more than that.

The prince replied, "Yes, it must be better to be strong, but I don't want you to be broken more than that. Jin liked this answer. Then,

I'll do my best to get it done.

The prince was overjoyed. The prince was overjoyed,

"I see!　Then you can use any materials in the warehouse!　I'll give you permission under my name!

With these words, he went to the back of the warehouse and came back with a document in his hand,

"Just show this to Jin and he'll let you through," he said.

He gave Jin a permit saying, "If you show this to him, the manager will let you through.

"Now, let's see what kind of materials we can find here.

With the permit in hand, Jin first rented a workshop in the royal palace. It seems to be a place where knight golems are usually maintained.

He had Lotte wait for him there, and half-excitedly headed for the materials storage area of the royal castle, pulling a cart carrying materials from there. It was located in a corner of the inner palace, guarded by two soldiers, and just inside was a guard of the castle.

Jin showed them the permit given to him by the prince, and they let him through right away. The officer came with him to keep an eye on him to make sure he did not do any catnip, but Jin did not have any intention to do so. In any case, it is a few steps inferior to the one in Horai Island.

However, there are still some valuable materials.

Jin has plenty of light silver and a good amount of bronze. In addition, he has decided to use a little adamantite, four magi crystals, and the leather of a sandworm.

Jin pushed the cart with the materials and returned to the workshop that he had rented from the prince.

When he returned to the workshop, he found not only Lotte but also the prince waiting for him.

"Your Highness!

"Ha-ha-ha, I skipped today's study just to see Jin fix Lotte."

Prince Ernest seems to like the golem a lot. No, he likes Lotte.

"Is it okay if I stay here and watch?"

Yes, please.

Jin doesn't dislike this prince who genuinely loves the golem.

He stopped Lotte's magic..,

"First, we'll strengthen the skeleton."

After explaining this, he begins to work.

"Oh, that's light silver, isn't it?　And that's adamantite."

He has a fair amount of knowledge, as he says he wants to make his own golem in the future.

"Yes, I will first replace the steel skeleton with light silver.

Jin then proceeded to form Lotte's skeleton with the same dimensions. A process that would normally be completed in a matter of seconds is done slowly for the prince's sake.

"Wow, Lotte's skeleton looks like this.

"We're trying to make her more human-like."

Jin continues to work while giving explanations from time to time. Next, the sliding parts are coated with adamantite.

"Oh, I see. By using adamantite on some parts, it prevents them from being worn out.

He has a very good understanding.

The next work is the musculature. <.

"Wow, I've never seen these techniques before. ......"

The prince stares at Jin's work as he says this. To be honest, a golem with muscles attached would be quite creepy, but the prince didn't care about that.

Finally, the most important part of the project, the installation of the magi device, seemed to be a simple matter of transplanting an already existing one,

"Your Highness, this structure protects Lotte from the .

Saying this, he holds out the magi device in front of the prince's eyes so that he can see it better.

"So this is the heart of Lotte. ...... Is this box mithril?　Is there some kind of magical formula engraved on it?

Yes, it's a magic formula that prevents magic from coming from the outside.

"There is such a magic formula!

<. The difference is that it is generated in a space and in an enclosure.

Jin says that he plans to inform the Minister of Magic of this method of protection against < after this, and resumes his work.

The body should be placed in the proper position on the chest and covered with magical muscle around it.

"This completes the first step.

Jin then waits for the prince to ask him a question. Sure enough, the prince asked a question.

"Hey, if you cover the Magi Device with mithril, it may not accept magic from the outside, but won't it be unable to extract magic from the inside as well?

This is a very perceptive question. Jin answers the prince's question in an easy-to-understand manner.

"Normally, that would be true. But do you see some lines coming out of this case?

Jin pointed to about six lines sticking out.

"Yes."

"These are the conductors that transmit the magic power to the various parts of the body. Each of them connects to the hands, legs, head, and torso.

I see. So there's no way for magic to travel in the opposite direction from those lines?"

The prince's comprehension was outstanding. Jin was pleased and started to explain in-depth.

"No, it does not. This line is made of mithril, which allows magic to pass through but not magic. The reason why is because ......"

I explained that magic is just a wave of energy, but magic is an energy that has a certain substance, so it is difficult for it to pass through a conductor of this thinness.

As expected, only about half of the students seemed to understand the explanation, but at least they seemed to get the idea that this is the way it is.

"Jin is amazing. He seems to know more than his teacher.

Prince Ernesto looks at Jin with respect. Jin smiles and resumes his work.

"Now, we are going to start the final stage of Lotte's rebirth.

With that, he removes the exterior of the old Lotte and transfers it to the new Lotte. What was missing was made up with the bronze we had brought with us.

The prince looks happy to see Lotte who regains her original appearance in a flash.

When all the exterior parts have been transplanted, only the steel skeleton remains. All the other parts were reused.

"Now, let's put the finishing touches on it.

Jin then returns Lotte's skeleton to a block of steel (ingot).

"Wow, how beautiful!"

The prince is impressed by the way the skeleton becomes a lump while he is watching. Jin's working speed is about one-tenth of his usual speed. Normally, the deformation would have been completed in a matter of seconds.

"Separating zinc. "

Separating the zinc used for rust prevention. The prince was muttering, "I wonder what zinc is..." But if I explained that much to him, we would run out of time, so we pretended not to hear him and moved on.

"<>"

This is the process of deforming the separated steel to form a disc. Yes, <>. This is also Jin's playful way of thinking that a tray is a maid's tray. But Jin doesn't stop there.

"<>. . <>"

"Wow, it's Bon Festival!"

Jin's special weapon, which can be used for striking and can also be thrown.

Jin also made several knives from the remaining steel.

Still there were some left over, so after thinking about it, Jin made a mop. It is a steel mop. It is also a very good striking weapon. He also made a tassel out of leftover sandworm leather.

Finally, I call on Laila, a member of the Royal Secret Maidens, who is waiting outside the workshop. She knew that she had been following Jin closely, even if it was just for work today.

"Ah, ah, um, may I help you?"

Laila was a little nervous to be summoned to a place where the prince was also present. Or maybe not just a little.

"Oh?　I think you're Iris's sister in the Magic Knights, aren't you?

Laila was a little nervous when she heard the prince's words,

"Ha-ha-ha-ha!　I am Aili's sister.

She bit it spectacularly. And it looks like it hurts.

"I knew it!　You look a lot like Aili!"

"I'm not as good as my sister ....... ......"

Laila looks down. Apparently, her sister holds a very high position in the Magic Knights.

But Jin had something to do with Lila,

"Your Highness, I would like to finish my business first.

The prince stopped talking,

"Oh, I'm sorry!　Laila, Jin has a favor to ask you."

Laila said.

"Yes, what is it?"

Jin then said what he wanted to do.

"Well, I need a set of samurai uniforms in the same size as yours. ...... including underwear."

"Huh?

Laila turns red and looks down at him, and Jin thinks she must have misunderstood,

"Look, this isn't your uniform," she said. <

I explain firmly. The prince offers to help,

"Look at this. We're going to put it on the golem. Isn't that right, Jin?

"Oh, oh, I didn't know that, I thought I was ........."

What was that supposed to mean? Jin wondered, but did not say so.

Lila left the workshop saying she would be right back, and returned in about five minutes.

"Oh, um, is this okay?"

"Yes, thank you."

Jin accepts the offered set of maid's uniforms with thanks, and first activates Lotte.

"Lotte,<>"

"Yes."

"Kya!"

Laila, who was watching from the side, let out a small scream of surprise. It seems that it is surprising to see a lying golem suddenly get up if you are not used to it.

"How are you feeling, Lotte?

Jin asked,

"Yes, father, I feel very well. Thank you very much."

Then she turns to Prince Ernest and kneels down,

Then he turned to Prince Ernest, kneeled down, and said, "Your Highness, I'm sorry for your concern.

The prince was delighted. The prince was delighted,

"Lotte, you are all right now, thank God!

She hugged him. Then he shouted in surprise.

"Lotte, why are you so warm?

Jin answered.

"Your Highness, in fact, Lotte has a magical circuit (magi-circuit) built into her that creates her body temperature.

This is a function built into most of Jin's automata and golems, including Reiko.

The metal golem is cold to the touch, so the purpose of this function is to solve this problem.

"Wow, you're still amazing, Jin!

The prince is even more impressed by Jin. Jin turns to Lotte,

"Lotte, put on the clothes there."

Lotte puts on the clothes and becomes a golem, a maid of honor.

With knives under her skirt and on her thighs, a tray under her arm, and a mop in her hand, she becomes the fighting maid of Jin's imagination.
