"Yeah, it's been busy, but it's been fulfilling."

"Hmm."

Jin is relaxing with Elsa on the back to Horai Island.

"Father, Miss Elsa, here is your tea."

"Oh, thank you."

Reiko made a pot of green tea.

Reiko is the only one who can brew tea without spilling even a drop of tea in the slightly bumpy flight.

"Ah, the tea tastes so good!"

Jin and the others return leisurely without using the warp gate.

Jin returned to Horai Island and asked the old man how the Franz Kingdom and the Shoro Kingdom were doing.

"That is good news. How is the Berlich workshop doing at ......?"

"I see."

Then Jin remembered.

"<>."

So he went to the workshop and decided to start work with Reiko as his assistant.

"First of all, the light ...... should be like this."

This is an option so that it can be attached to the one currently being manufactured at the .

I'm going to place an additional order for this one.

"And ...... and... a tail instead of three legs, huh?"

The two-legged movement will make it easier to control.

And the outrigger-like use of the tail will help stabilize it during work.

"Like this?"

But since this was the first time to use this method, even Jin had to fine-tune it about three times.

"That's it."

Finally, the air conditioning.

"Let's make a dust-preventing boundary generator an option."

This is an option to prevent dust from being inhaled when digging in rock walls and bedrock.

It can also reduce the heat when working in the hot sun.

"Father, why don't you just install it from the beginning?"

Reiko says,

"No, it would cost too much to install everything.

Jin replies, "Is that what you mean?

"Is that what you mean?"

"That's right. If it was made in Horai Island and used in Horai Island, I would put everything into it as much as possible.

But this is for general use, a consumer product, so we have to consider the cost, Jin said.

"So that's what you mean. I understand."

Jin and Reiko completed the new model with options in about 10 minutes.

"So this is it."

However, Jin thought that it would be better not to bring this to the Shoro Empire at once.

He thought that it would be confusing to bring in an improved model when even the initial model was in the middle of mass production.

"I think it would be better if it is just an option."

So he decided to talk about the possibility of adding <><> as two options.

Elsa, on the other hand, was keenly aware of the need to revamp the automata for educational purposes based on this lecture.

In the past, there existed an automata for educational guidance called <>.

Recently, Jin has also donated an automaton <> for <> to teach the <>.

Erza, in consultation with the old man, concluded that it would be necessary to create an automaton for teaching medical skills.

"This is something I should discuss with my brother Jin.

Erza decided to give an explanation during lunch.

She explained the situation to him at lunchtime.

I see, it is certainly necessary. Why not <> at ......?"

<> is a female medical automaton developed by Jin and his colleagues. Saki has been testing <> as an assistant for now.

"Hmm, it's a little too advanced," she said.

It's not natural to lend it out for free, Elsa said.

"Well, that's true ......."

Jin wonders how he can provide automata or golems for educational purposes at a low price.

And finally,

"Yes!　How about replacing the control core?

He came up with an idea.

"Ah, that's it."

Erza seemed to understand what Jin meant.

"That's my brother Jin.

"As I recall, we gave a golem maid named Saffi to before, didn't we?　What about it?

The old man answered.

<

"Oh, that many?"

<

"I see. I'm not so sure about going back to ...... then ...... hmmm...."

Today is April 14. He had just returned from yesterday, so he was somewhat busy, he thought.

<

"Ah, that's a good idea."

The data came from Erza and the <> came from Jin. And Makina will do the conversion.

This should not be a problem.

But the old man has a word of advice.

"Yes, that's right. Then let's make it possible to <."

The procedure is as follows,

1. replace the old <> with the new >.

The data area of the new <> is already loaded with the medical knowledge prepared by Elsa. 2.

2. transfer the experience data stored in the old .

"Yes, that's good."

Elsa agreed,

"Then, let's have that stopped working repaired as well.

Jin said.

"Erza, prepare the data for education. I'll get the control core for the replacement.

"Okay."

Immediately, Reiko, the old man, and the <> were mobilized, and Jin and Erza set to work.
