Jin had been depressed since Marikka's death.

"Father, are you all right?"

Reiko asks, concerned,

"I'm fine."

But he only replies, "I'm fine.

The Marikka incident had taken a toll on him more than he had expected.

"......I'm afraid I'm going to have to see my acquaintances off for a long time to come,......" she said.

Rubina and her family have returned to .

By the way, Ellis and Freddie were invited to Greena's house.

So, Jin is the only one who is in Horai Island now.

This made Jin feel even more lonely.

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

"Old man, do you have any good ideas?

Reiko thought better of it and asked Laicun for advice.

"Is that so?"

<

The old man said, "But I guess you are conflicted about whether it is really a good idea or not to do so.

.

"Oh, yes, that's right. Your father has seen off many people, Martha, Emperor Taisho, Myrne, Milowina, Stearina, Vivien ....... Each time, as now,......"

<>

"...... but you, my dear, have already told me about that. ......"

<>

"Is it?"

<

What is the reason for that?

* * * * * *

Another few days passed.

Jin was holed up in his workshop.

"Father, where is this?"

"Oh, it's over here."

Reiko helped him, relieved that Jin could not spend his days in idleness after all.

Right now, Jin is building a teacher's automata that can teach the .

Of course, he will not teach it to the highest level. We are only trying to teach the basics.

After that, we want the students to devise their own ideas.

If the result is something different from what Hitoshi has in mind, that is fine with me.

I am the legitimate successor of Adriana Barbora Tsetsi, and my disciples are on and in the . In other words, his skills and thoughts have been passed on to his direct descendants.

"We can leave it to <>. Leave it to Machina to take it to ......."

Jin thinks that we should stop interfering too much in the world.

"Except in the case of a global disaster or a world war."

Jin mutters to himself so that Reiko and the old man can hear him without talking to anyone.

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

<.

"Oh, you saw her, Machina-dono?"

"Yes. And he has donated an automaton named "Lehrer" to us.

Chief Superintendent Tomax Bartmann received a report from the secretary automaton Manon.

"<>?"

"Yes. <

"Oh, that's great!

After that lecture, I was inundated with inquiries from people who wanted to learn how to make Golem automata in the Adriana style.

"We have ten of them, from Lehrer 1 to Lehrer 10, so I think they should be enough to serve as teachers for the time being.

"Yes. I would like to train technicians with these ten as teachers and prepare them for the future.

Tomax Bartmann nodded.

"Then, how about five of them for training technicians and five of them for teachers?

"That's a good idea. Anyway, we have to carefully plan our future technology promotion plan."

* * * *

"That's one."

On Horai Island, Jin counted down his fingers.

"Next ...... let's ...... make that one. Reiko, lead, tin, and antimony. ...... No, not that one."

The metal that Jin had just mentioned was for making .

The reason I stopped halfway was that this alloy is relatively soft.

The reason for this composition, then, is that it has the following advantages: it has a low melting point (about 240 degrees Celsius), it flows well when poured into a mold (small letters can be formed), and it has a low solidification shrinkage (it is not easily deformed by shrinkage when it cools). (i.e., it is hard to deform due to shrinkage when it cools down).

However, Jin was thinking of using <> to make the printing block, as is typical in this world.

"We can do it by using <>, can't we?"

The letters in this world are similar to the alphabet. Even if we include numbers and special symbols, we can manage with less than 100 types.

"The method of combining type is good, but it would be faster if we could make the block at once using .

However, only a handful of engineers can do such a thing.

But that is not the end of the story for the Magecraft Meister.

"All you have to do is create a special Magi machine.

The part that corresponds to the scanner is the <. Jin thought that it would be sufficient to process the data with a special , convert the characters into a certain font, and process the metal plate by <>.

"The mechanism for printing with this is much simpler."

Automation using a golem arm is also possible.

"Let's leave that to ordinary engineers, too.

And so, Jin builds a Magi machine that prints handwritten manuscripts.

What?

What?　Makina-dono is here again?

was surprised that Makina had come again after a day's absence, and at the same time, she was amazed at the Magi machine that Jin had donated to her.

"Ummm, this is a great idea ....... Perhaps it is an invention based on the printing of the other day. ......"

<, it is possible to make a print as many times as you want.

It can be called a revolution in printing technology.

"That's what the <>> is all about: ......"

Tomax Bartmann immediately began to consider how to put this to work.

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

"Yes, my lord. After all, your father is the one who makes things.

In Horai Island, the old man and Reiko were relieved.
