Jin finished giving instructions to his subordinates.

"If it were true, I would have discussed this with Reinhard.

He has been visiting his father, Count Wolfgang Randall, for the past day or two to report on the management of the estate for the first half of the year.

"I wish I had talked to him about it before.

Erza said, "I should have consulted him before," but it was no use, since she was occupied with the specifications of the monorail and had not yet come up with a plan for the guest house.

"I'll talk to Reinhardt when he's available."

"Yes, I think that would be a good idea.

All that remained was to make a model.

This is the true work of Jin.

<.

However, there is one big problem.

"......I can't motorize. ......"

Motorization is the process of making plastic models and other models move with motors. It is different from display models that are just for decoration.

In the late Showa period, before the bubble economy, most plastic models were motorized, but by the time Jin was born and raised, such models had already begun to decline.

However, Jin preferred motor-driven models, even if they were inferior in detail.

If Jin just wanted to have fun on Horai Island, he could use a golem engine or a force field generator, but that was not the case for something that was to be displayed in public.

"Well, at least until it can be moved by hand.

Some compromises have to be made. It is not something to play with.

"The size ...... should be, well, about the size of a tatami mat."

From Jin's memory, a piece of tatami ...... is 180 centimeters by 90 centimeters, or 6 feet by 3 feet. The size of a piece of plywood was one of the standards.

So, we will prepare a 180 cm by 90 cm board this time, too. It is not plywood, not a single piece of plywood, but a laminated wood made by <>.

"Father, can't we use a single board?"

Reiko, my assistant, asks.

"We have enough lumber in stock to make a board about one meter wide.

The island of Horai, located in the subtropical zone, has good plant growth, with coniferous forests on the north side of the island and broadleaf forests on the northeast side, and there are many large trees.

"Oh, I don't care about the grain this time, and laminated wood is less prone to deviations."

One-plywood is used for table tops and mirror boards of wardrobes, etc., partly because of the beauty of the grain, but on the other hand, it can warp due to changes in humidity.

Plywood and laminated wood are less prone to warping.

"Father, I understand."

"Well, now that the boards are ready, the next step is the layout.

The easiest layout would be a single letter. The rails are straight and the model cars move back and forth on them.

Endless is also easy. The point is a circle, but it does not have to be a circle, it can be an oval, or even a figure 8 if you cross the rails.

However, these are also classifications to reflect the precautions to be taken when applying current to the rails, so they are not really relevant to the present Jin.

"Since this is for demonstration purposes, I'll put both single letters and endless."

Since there is no Styrofoam type material, wood is used. Jin is building an elevated track using lightweight wood similar to balsa.

The first character is a round trip, and the image is a line connecting King's Landing and the port.

And endless is a circular line, a line that goes around the cities.

Since only boards are not enough, sawdust is glued to the ground and thin boards are colored to resemble cobblestone pavement.

As Jin came on board, he also began to make buildings out of thin boards, turning them into dioramas.

Erza, who came to check on the diorama after the gyuuhi was finished, rolled her eyes at the diorama she saw for the first time.

"...... interesting."

And even more than that, she was amazed by Jin's happy face.

（Jin looks happy. (Jin brother, you look happy...the most so far...)

When Jin is making something, he is always serious, but now his expression is also relaxed.

Erza thought that she did not fully understand Jin yet, because she had never seen such a serious yet happy expression on his face.

But it was almost dinner time.

"Father, it's almost time for dinner.

Jin looked so happy that it was hard for Elsa to speak to him, but Reiko took her place and said.

"Oh, it's almost that time already. Okay, we'll have some more after dinner."

Jin washed his hands, gargled, and went to the dining room. Erza followed him.

"Brother Jin, you looked very happy.

Erza told Jin over a cup of tea after dinner.

"Oh, really?"

"Yes. I thought he really likes making things like that.

"Maybe."

Jin can't deny that.

"I think it's because it's a complete hobby, or it's not an obligation, so there's no responsibility. ......

It's hard to say, but it's fun," Jin concluded.

"......I can kind of understand, maybe."

I guess it means that the mindset of those who do the same work is different between a job and a hobby.

There are even people who say, "Don't turn a hobby into a job.

After putting these discussions to rest, Jin resumes working on the prototype model.

This time, Erza is willing to help him, but Jin quietly proceeds by himself.

Elsa felt a little sad, but seeing Jin's happy face, she could not say anything.

An hour passed.

"It's done!"

The diorama-style monorail model for the demonstration is complete.

"It's amazing!"

Elsa praised it with all her might.

The monorail now looks more like a part of the Diorama than a demonstration model of the monorail.

"I haven't made a model in a while, and I got a little mad."

Erza smiled and looked at Jin who scratched his head a little embarrassed.

"I found Jin's childishness."

* * * *

"Yes, it's rather tasty.

Jin, who tasted the prototype of honey beans with gyuhi as a substitute for his evening meal, gave it a score of 80.

"It's not soft enough. ...... What else do we need?"

"It's hard."

As Jin and Erza were twisting their heads, Perid Reader came in with another prototype of Gyuhi.

"Master, please try this one too.

"Let's try this one. ...... Yes, this one tastes better."

"Really?　...... Oh, really."

"I mixed it with syrup."

"Taffy. ......

They have successfully tried to make syrup from malted barley and glutinous rice, so they used that.

Perido's idea is that of a first-rate confectioner and cook.

"Now I'm going to change the ratio of the ingredients and try various things," he said.

"Yes, I'm looking forward to it.

"Yes, I'll leave it to you."

Now, it looks like he will be able to make delicious honey beans. Jin was happy.

Before he knew it, it was already around 10:00 p.m.

"Let's brush our teeth and go to bed.

"Yeah..."

Jin stretched out his back with a satisfied look on his face, saying that he had had a productive day.

The moon ...... was shining in the sky.
