Jin explains the new automata/golem control theory.

"Well, I understand the theory, but will it work so well?"

Reinhardt was skeptical,

"Jin, I can sympathize with your idea. If there is anything I can do to help, I will."

Saki supported him.

This can be said to be the difference between Reinhardt, who is the actual producer, and Saki, who is purely concerned with theory.

In other words, Reinhardt knows how difficult it is to put theory into practice.

Jin, I understand your theory. But first, how do you reproduce the sense of touch?　I think that's the first step."

Reinhardt questioned, but Jin had a theory.

<

Jin was trying to reproduce it using materials from this world.

If he could reproduce it, he could attach it to several points on the body, and by detecting the strain, he would be able to know the pressure applied to the body. In other words, it is a .

Jin explained the principle of its operation, adding at the end

"All we need is a material whose magical properties change drastically when it bends or deforms.

"Hmmm, magical properties, huh ......?"

Actually, Jin had an idea. The wing membrane of a sea dragon. It is the material used for Reiko's skin.

However, it is so uncommon that it could only be used to improve Reiko.

"...... I've got one."

Saki said and pulled out a crystal from the shelf.

It is a translucent crystal with a red interior and a green cross section around the periphery. The image was that of a watermelon.

"Ah, watermelon tourmaline. ......"

Jin mutters unintentionally. A girl I used to be interested in was wearing a small pendant with such a color.

"Water melon?

"Tourmaline?"

Saki and Reinhardt responded to different words. Incidentally, it was Reinhardt who responded to tourmaline.

Ah, water melon is a fruit or vegetable with green outer skin and red fruit inside. Tourmaline is ...... a stone like that."

"Hmmm....the water melon is called water melon in Jin's language. Come to think of it, it's time to plant some seedlings."

Saki told us that they planted shiitake seedlings in the garden every year and harvested them in the summer for eating.

Jin wanted to get his hands on some of those seedlings or seeds. Of course, his intention was conveyed to Reiko, who contacted the old man and was directed to the 5th Quinta, who was newly dispatched to the Shoro Kingdom.

A quiet word.

"This stone is called elbaite. When power is applied to it, it produces a small amount of magical power. Can't we use it well?"

Jin nodded at Saki's explanation.

"Yes, let's slice it into thin slices and attach the mithril wire to it.

Immediately Jin sliced with Saki's approval using engineering magic.

"Mm-hmm, it's nice to have a magical engineer!　I myself can hardly use magic, so it's nice.

I can analyze and sense magic," Saki continued.

"All right, then, Saki hold that mithril wire for me. I'll try to apply the power to the sliced elvite on my side.

"Okay, Jin."

A small piece of elvite with about a meter of mithril wire connected to it. Jin put it in his palm and pressed it gently with his finger.

"How's that?"

"Mm-hmm, there is magic on this side."

"I see!　That's a success!

At this point, Reinhardt, who had only been silently watching from the side, seemed to have lost his patience.

"Ummm, Jin, Saki!　Let me help you!　I mean, I can't stand to just stand by and watch with my fingers crossed at this moment when a new technology is about to be born!

It seems that Reinhardt was also a magical engineer.

From then on, the three of us repeatedly experimented with different thicknesses and sizes of elbaite to determine the optimum shape.

Thanks to their efforts, by the end of the evening, they had completed a <.

I decided to make an automata using this sensor. And I will give the first one to Saki.

Jin and Reinhardt were of the same opinion. Saki could not disagree with them.

"Yeah, well, if you both say so. Besides, I want to try some things.

The next thing I know, it's already getting dark outside, so I call it a day.

"Reiko, how much maple syrup is ready?"

"Yes, father, that's all."

That's about seven parts of the pot that Jin had made. About a liter.

"Okay, let's fill the bottles half full.

With these words, Jin magically formed two jars out of crystals and filled them with maple syrup.

It is a very expensive bottle. The lid is also made of crystal. It is not the kind of jar one would normally use to store foodstuffs, but considering the rarity of the contents (for now), it might be appropriate.

Saki, not to mention Reinhardt, seemed to have gotten used to Jin's out-of-standardness after today, and did not say anything.

"Well then, let's take one of these to Reinhardt's house.

"Yeah, that's a good idea. I need a sample to tell my father about.

So Jin, Reiko, Reinhardt, and Saki got on Jin's carriage and went to Count Randall's house.

"Welcome home, Mr. Reinhardt. ......?"

At the house, Berthe came out to greet her, but her complexion changed when she saw Saki.

"Hello, Berthe, it's been a long time. Congratulations on your engagement to Reinhardt.

But Saki didn't seem to mind, and said the greeting.

"........."

"Yeah?"

"...... what are you doing dressed like that!"

Bertsche's voice said that she was truly stunned.

"Your hair is shaggy!　Your skin is shaggy!　Dirty clothes!　Dirty clothes!　...... and you smell a little!"

Bertsche, who had criticized Saki's outfit from top to bottom, said,

"Master Reinhard, I know you're hungry, but I'll give you an hour!"

With that, she dragged Saki away.

"Ha, Berthe has known Saki for a long time. Saki seems to be weak against Bertsche."

Reinhardt laughed as he watched them walk away.

"Jin, it's going to be a while before Bertsche and Saki come back, so why don't you come to my workshop?"

With an invitation like this, there was no way Jin could deny the invitation.

Reinhard's workshop was built in the courtyard of the pavilion. It was a sort of detached house. There was a passageway with a roof and walls so that visitors could come and go without getting wet, even in the rain.

"Wow, it's spacious.

The room was about 20 tatami mats in size, quite spacious.

"This is where you made the Black Knight (Schwarzlitter)," Jin said.

Reinhardt nodded broadly.

"Well, please sit down.

Reinhardt invited Jin to a table in a corner of the workshop and offered him a chair.

"You won't be disturbed here.

He seems to have something important to say. Well, Reiko is with him.

"I thought it would be a good idea to talk to Jin," he says.

Reinhardt began to speak.

"Saki's mother is dead now, but she is the eldest daughter of a marquis.

"What?"

He suddenly started to say something very serious.

"You see, this is the marquis who asked Erza to be his wife, the Marquis Gehlen Theodoric von Eisen. His domain is to the west of ours.

His eldest daughter and Saki's father fell in love, eloped, and had a daughter named Saki.

"Let me tell you a little about the Marquis Theoderic. The Marquis is fond of women who are ...... a bit small."

"What?"

Reinhardt, who seemed to be having trouble explaining, explained that the Marquis seemed to like women who were still immature, who were on the verge of turning from girls into women.

"So, he has three children now, four if you count Saki's mother, all daughters. He seems to be worried about the fact that he has no male heir. So when his wife passed away last year, he asked for Erza, whom he had been eyeing for some time, to be his wife."

Reinhardt has been gathering information since he returned to his hometown.

"I see. ......, how did he treat Saki?"

"Oh, I digress. Saki's father, Mr. Tohr Eschenbach, is now one of the top alchemists in the country, so they are not openly hostile to him. In the first place, he's living in a neighboring territory, and he's left it that way."

"I see."

But he seems to love his grandson Saki and often tries to take her into his own hands. But Saki refuses and continues to live there.

Reinhardt laughed a little sadly.

"Compared to the marquises, the counts can't do much when push comes to shove," he said.

That's how feudal society works.

"The only people who can speak to the marquises are the dukes above them, and then the emperors. Even then, it's not against the law, so I can't say anything strong about it. Whether he takes Erza or Saki.

The Emperor is not a dictator. He does not and cannot ignore laws and customs.

"Well, I know it bothers you to hear this, Jin, but I thought you should keep it in mind in case something happens in the future. I'm ...... sorry about that."

Finally, Reinhard bowed his head.

Jin had had enough trouble, but he liked Saki enough, even though they had just become acquainted, to smile and tell Reinhardt, "It's nothing.
