Jin and his friends have been at the Marcia workshop since the morning. Prince Ernest and Princess Rieschen had not arrived yet.
"First we have to fix the Arrow.
I'm sorry, but I had a victory party last night and I had to put it off.
Jin, please.
"Yeah, I'll take care of it."
Jin first puts Arrow down on the workbench and stops the movement.
Then, with Elsa, Reiko, and Edgar as his assistants, he begins to disassemble the Arrow.
Meanwhile, Licia and Hannah are being shown around the workshop by Marcia.
After removing the exterior and musculature, Jin first checks the skeleton.
Yes, the skeleton is in good shape. The joints are all fine.
That's my brother Jin!
Now, ......
Then a voice rang out.
"Ah! Jin, you can't start without me!
"Ne, Nest-sama," said another voice in a quiet voice, "......."
It was Prince Ernest and Princess Rieschen. It was only 8 a.m. when they arrived.
They were accompanied only by Lotte and Tia. Reiko guessed that there were a few people around to escort them.
Prince Ernest strode up to Jin,
"So this is Marcia's arrow. She's going to be my Lotte's sister, isn't she?
He said with interest.
"I guess so."
Jin answered, but did not stop.
"Reiko, give me 64 light silver."
"Yes, father."
Edgar, you hold this side.
Yes, Master Jin.
With two assistants, the work is fast.
In no time at all, the left arm was regenerated and the muscular system was reattached.
Of course, all the joints in the body have been checked for clearance and adjusted.
"It's always brilliant to see ......."
Prince Ernesto admires Jin's skill.
"Yeah, no problem."
After a full body check of the Arrow, Jin begins the reassembly and finishes it in less than two minutes.
"It's fast. ......"
"......"
Prince Ernest mutters a single word, and Princess Rieschen is absolutely mortified.
Jin restarts the Arrow and asks how it is.
Yes, Jin-sama, everything is fine. I can be of more help to Marcia than ever before.
"I am glad to hear that. I'm glad to hear that. ...... Your Highness, this would be a good time to check on Lotte and Tia as well, wouldn't it? Marcia, would you mind?
"Yes, of course."
Marcia nodded her head in agreement. And there was no way she could deny the two princesses.
What? Oh, yes, we'd love to have you!
"Yes, by all means!
So, Jin decided to borrow Marcia's workshop to overhaul the two machines.
Since Tia had a lot of work to do, he asked Elsa to disassemble her.
In less than five minutes, the two bodies were disassembled to skeletal state, and Jin was checking them in front of them.
"Yes, the adamantite coated joints are not worn down at all. They are in good shape."
He then reassembled them, adjusting the clearance and balance.
The muscular system seemed to be in perfect condition, as if he had not done anything rash.
However, Jin does not intend to simply assemble them as they are.
Originally, the muscular system of both of them were made of materials from powerful demons. In other words, their power can still be increased.
Jin increased the efficiency of Tia's ether converter and mana driver, and loosened the limiter of her magical muscles by the same amount.
This should have doubled the reaction speed and increased the power by about 1.5 times.
At the same time, Lotte, who had been a mana tank, was upgraded to an ether converter and a mana driver similar to Tia's at this opportunity.
"Wow, I don't know what I'm doing. ......"
Prince Ernest sighs, while Princess Rieschen remains silent.
Jin then begins the assembly. Erza was left to install Tia's magical skin, while Jin assembled Lotte.
Time required, approximately 10 minutes.
"How are you doing, Tia?
Jin asks the two reactivated bodies.
"Yes, very good. Thank you very much.
"Yes, even better than before. Thank you very much.
Both of them seem to be in good shape.
"Okay, that's it. Let's get to work."
"What?"
Prince Ernesto asked,
"No, no, no, you're going to ask him about the ship, right?
Jin said,
"Oh, that's right. I was so caught up in Jin's skill that I forgot about it.
Prince Ernest scratches his head.
The first thing is, what is it that you want to know?
"I think it's important to know what you want to know first.
Jin said, "I want to be clear first, because time is limited.
"Yes, I understand that, but I'm ...... getting confused."
Prince Ernesto makes a good point. Marcia's workshop is filled with materials, documents, and actual items related to the ship.
"I'll leave it to Jin and Marcia. I can only be here until the end of the morning ...... or rather until 11:00 a.m. I have a luncheon with Miss Trine at 11:30 a.m. I'm meeting Miss Trine for lunch at 11:30."
"Yes, I understand."
Prince Ernest laughed as he said that it was his royal duty to help out Trine, who came from the Kingdom of Egelea.
Prince Ernest and Princess Rieschen had to make time in their busy schedule.
Jin thought a little about how to teach them everything about boats in a short time and concluded that it would be better to start from the basics.
"Well then, let's begin. First, do you know why a boat floats?
"What? Uh, because they are light?
"I'm not saying you're wrong, but ...... let's start there."
Jin prepared a whiteboard made of a kind of subterranean spider resin (GSP), a gift from Marcia in her workshop, and began to draw a diagram on it.
"First of all, when you put an object in water, the object becomes lighter by the amount of water you push away. I want you to remember this as a premise. I can't explain it, even if you ask me why.
"Yes, I understand."
"Well," he said, "that is, objects lighter than the weight of the water you push away will float, and objects heavier than the weight of the water you push away will sink. This is true even if the ship is made of iron."
"Ah, so that's why those boats we saw in the Kunlun Islands floated!"
"That's what I mean."
"I see... so that's how it is! I had a hunch about it until now.
"What?"
I noticed that Marcia and Rodrigo were also listening to Jin's lecture.
"Jin's talk is very informative. Can we listen in too?
"Of course we can."
Jin nodded to Marcia and continued his explanation.
