Jin and the others returned to the front of the institute.
Jin said,
"We still have some time left. ......"
He then muttered to himself,
"All right, bring out the <>, Mr. Mere Old Man.
He gave the order.
<>.
The old man replied immediately, and one second later, <> appeared in front of the laboratory.
"Wow!
"Wow, you scared me. ......"
"Sorry, sorry. I just had some time to kill, so I thought I'd explain something that was bothering me the other day.
"What was on your mind?"
Rubina tilted her head.
"Yeah. The problem with Rubina's giant golem."
"Oh, by all means!"
Rubina's eyes sparkled. Seeing her happy face, Jin thought it would be good to give such practical advice to others.
"I was careful when I made this < at ......," Jin explains.
Jin explains.
The balance between strength and weight changes as it gets bigger.
The motion around the joints can be expressed in terms of <, i.e. how many seconds it takes to move how many degrees, which means that for the same angular velocity, the end velocity will be greater as the angular velocity increases.
"Okay. The area increases in proportion to the square of the size. The cross-sectional area is the same. But the weight is proportional to the cube, right?
"That's what I mean."
At Rubina's level, she still does not fully understand <>, and Jin is also unable to give a detailed explanation since he has only memorized some of the concepts and formulas.
However, Rubina seemed to have understood what she needed to know, even though it was only a brief explanation.
"I'll try to improve it when I get back!"
"Yeah, good luck!"
Jin smiled at Rubina who was full of motivation.

Then it was time for lunch.
The menu was tempura soba. You can choose between hot and cold soba.
"The soup stock is very good.
The batter of the tempura is crispy.
The tempura batter is crispy." "Wow, the wasabi is good!
Everyone seemed to be familiar with the dish and enjoyed the taste of Horaijima style.

After lunch, I decided to give them a tour of the institute.
However, it was not so different from the one in Onogoro Island, so the tour ended soon.
However, I only explained about the previous generation's study from the outside of the door. Jin's room, however, I showed him the inside.
Then Jin decided to show a picture he had been thinking about showing or not.
"Here, this is a picture of your ancestors."
"What?
It is a group photo taken 400 years ago.
I've never seen it before!
Since they moved to Onogoro Island after the dissolution of the <>, I thought they would not have any pictures of their ancestors from that period.
Jin thought that they were probably kept in the family scattered in various countries, and it seems that he was right.
Incidentally, the old photos of the family members, including Jin, have been kept in a secret place because of the old man's concern for them.
This is Bina and next to her is Luis. This is Bina, and the one next to her is Luis, Rubina's direct ancestor.
Trichardt and Suzanne looked very pleased with themselves.
"And this is Elsa. This is my wife."
"She's beautiful. ......"
Seeing the picture of his beloved wife, Jin's heart ached a little, but he managed to keep it from showing on his face, probably due to the fact that he was a duplicate.
"Come on, come on, let's move on."
Let's move on." * * * * *
And he went to the workshop.
"Wow, this is amazing!
"This is Master Jin's workshop?
"This is where many legends were born. ......"
Everyone was deeply impressed. Jin was a little embarrassed.
"Ah! There's an unusual material!
Rubina exclaimed.
Curious, she walked around Jin's workshop and found a shelf of materials.
"Oh, they have sample materials there."
Jin sometimes wonders what materials to use.
In such a case, when he sees the actual materials, he sometimes gets a flash of inspiration. >>Sometimes it hits him.
And what Rubina found was a shelf of metal samples.
A 1 mm thick, 10 cm square plate and a 1 cm diameter, 10 cm long round bar.
