"By the way, how are you going to unveil the ?"

Erza suddenly spoke up and said what was on her mind.

"Well, I don't know, I lost the timing to tell you.

Jin said, "When I saw how hard they were trying to realize their idea, I didn't want to show it off.

"I ...... understand a little bit."

Then, Jin said to Erza, "I know a little bit about it.

"To be honest, I'm a little bit envious when I see engineers walking step by step like that.

"What do you mean?"

"......When you're learning something, the most fun is when you know you're getting better."

Jin said, "It's the most fulfilling and fun when you realize that the more you practice, the more you improve.

"I think I understand."

Elsa gave a small nod.

"But there are things you can do only because you are skilled.

There are many things that can only be done at Jin's current level, or rather, only by him, Erza said.

"That's right."

Jin felt his shoulders relax at Elsa's words.

"Thank you, Elsa."

"You're welcome."

Jin smiled a relaxed smile.

The time was 7:00 p.m.

"Well, I guess I'd better go to the then."

This is the laboratory to which Kachea, Eira, and Gromma Trey, whom he met on the Pandor continent, belong.

"Well, have a good day."

Elsa said she would stay in the guest room.

"I'm giving a lecture tomorrow."

Right.

She's been asked to give a special lecture on medicine.

Jin left the guest room accompanied by Reiko.

"Welcome, Jin!

"Mr. Jin, it's been a long time.

"Welcome, Mr. Jin!

Eira, KaChea, and Groma greeted me.

"Hey, where are the other members?"

Jin asked as he was ushered into the laboratory, which was deserted.

"Everyone has already left for the day. Fifi told us that Jin was coming, so we waited for him here after dinner.

Eira's words made Jin feel a little sorry.

"I see. I'm sorry I came all this way.

"Don't worry about it. We're friends, aren't we?　Hey, Cachéa, Groma...

Yes. Don't worry about it.

"If I can meet and talk with Jin-dono, it's nothing.

All three of them laughed and told me not to worry about it.

"I see. Then I guess I should say instead of sorry."

Jin laughed back.

There was a solid friendship there.

"So, how are things these days?"

When Jin asked a vague question, Katya was the first to answer.

"I went back to my hometown for the New Year's holidays.

"Oh, is that so?"

"Yes. My mother, aunt, and Helga are all fine.

Katya told us about her mother Tanya, her aunt Sonya, and her friend Helga.

"So, there are already regular flights to the continent of Pandor?"

"Yes. The number of flights was increased during the year-end and New Year holidays.

This kind of response is unique to Avalon.

Didn't Eira return?

"Yes. I wasn't born in the Principality of Mercana.

Oh, I see...

Jin only knew that he was an engineer invited from one of the four duchies on the Laurentian continent ......, Norway, Mimaka, Jagus, or Dalat. Eira also did not tell him.

And Jin did not think of forcing him to ask about it, assuming that there must be some reason.

"Not recently, but Berlich Becker went back to the Shoro Kingdom, so I think he would be envious if he knew that Jin-dono came here, don't you think?"

"Well, I don't know.　Well, Groma, you should speak more easily."

"...... got it."

Gloma Tolley did as Jin asked and changed to a more casual way of speaking.

"Berlich can't afford to leave his workshop so much free time, can he?"

At that moment, Jin noticed that Katya was blushing a little and decided to ask her later if she had made any progress.

Now it's more about technology than about talking.

"We are now planning to mass-produce this kind of thing in the Shoro Kingdom at ......."

Jin showed Reiko the rough sketches of the > he had brought with him.

"Wow ...... this is interesting, Jin!"

Eira was the first to show interest.

"This ...... is quite cost-effective, isn't it?　Is the goal to spread the word?"

Cachia said.

And Gloma Trey said,

"I see, the purpose is to prevent military diversion, to reduce the cost, and to promote the use of the technology.

He looked at the rough sketches with a keen interest.

Then he slowly opened his mouth.

"Do you think the three legs are for stabilization?"

"That's what I meant."

"How about a third leg like a tail, so that when it walks to move, it walks on two legs, and when it wields its power, it uses its tail like a leg?

"Oh, I see."

"Then, the sole area should be a little larger, shouldn't it?　You weigh a lot, don't you?"

Eira also gave his opinion.

"Yes, about 600 kilograms. ...... I see...foot sole area.... That's a good idea.

Other opinions came up.

"If it's for construction, it should have a light, right?"

"Yeah, sure."

Hitoshi nodded in agreement with Groma's opinion.

Certainly, it is not as if there is no nighttime work, and the addition of lights would not increase the cost too much.

"And what about a safety belt to prevent the operator from falling off?"

"That might be a good idea."

Eira's words reminded Jin that even modern Japanese passenger cars had seat belts.

"Oh, and not a direct improvement idea, but do the workers wear helmets?"

Katya pointed out something that Jin had forgotten.

"Some of them wear helmets, and some of them don't."

Jin felt that it was necessary for all workers to wear helmets.

"I think that some people may not like to wear helmets if they are not used to them. So I think it would be good to make the helmets themselves magic tools and make people think <>."

Ka-cea gave me a good opinion, and I was grateful for it.

It had been a long time since the three of them had met, but they offered their opinions from different perspectives from <>, and Jin was happy to hear their valuable opinions.
