After about five minutes, Jin came back to himself as Zion said.
"...... I beg your pardon, Hilde-sama."
Jin apologizes to the Grand Emperor (Hilde).
"I'm afraid I've fallen completely into my own world.
Jin apologizes.
But Hilde laughs and forgives him.
"It's okay. It was interesting to see you thinking so seriously about something.
"...... thank you."
"So, what did you come up with?"
Jin started to explain to Emperor Taisho (Hilde), who looked very curious.
"Well, this bone..."
Jin held out a small bone in his hand.
"The main ingredient of bones is calcium phosphate in most living creatures, and it is the same in Siamese dragons. However, in the case of a pseudo dragon, it is thought that it is reinforced with organic matter and magic power to strengthen it.
"I can sort of see that."
"So, Zion said that the bones are heated and used, but I thought of another use for them."
What's that?
"Here's how. ......<<>"
After leaving the main ingredient calcium phosphate and eliminating the other ingredients, crystallize the material.
This results in calcium phosphate crystals, which are transparent hexagonal prisms.
"Well, it's beautiful.
But Hitoshi looked reluctant.
"Yes, well, transparent crystals are beautiful, too. ......"
"What's wrong with it?"
Jin nodded.
"Yes, the color ......."
Calcium phosphate is also called < or , and its mineral name is .
It is popular as a mineral specimen because of its various colors depending on the impurities it contains.
With a hardness of 5 on the Mohs scale, it is relatively soft and easily scratched, so it is not often used as a gemstone for accessories, but it has been popular among collectors.
Particularly popular were those with a deep blue-green color, like that of the ocean floor, which is what Jin expected.
"I see. So it could be used for such a collectible artifact. ...... Zion-san, don't you think this could be a specialty of the ?"
"Oh, yes, I think it will."
As expected of the Emperor Taue (Hilde), she instantly judges that this could be a viable industry and advises Zion.
As a side note, Zion, who would later play an active role in domestic politics as the wife of the clan leader of , was nurtured through this experience.
"Jin-kun, why don't you study her to find out how to produce such a color?"
Yes, that's what I'm going to do.
Jin was pleased that he had once again found a subject that Saki would be pleased with.
Saki was happy to have found another subject that would make her happy.
"Well, let's make something then.
Jin processed the calcium phosphate crystals he had just produced.
"<>"
"Ah!
Flora shouted. She had seen Jin's serious engineering magic up close, so it was not surprising.
By the way, the other participants are used to seeing such things and were unmoved. No, one of them .......
"I haven't seen Jinshama's technique in a long time!
A brass nail lying at the back of the shelf is < to make a pin, and the tie pin is complete.
Of course, you can use it as a brooch as well as a tie pin.
"Wow,......, you are as vivid as ever."
"It's beautiful. ......
The center of each transparent petal is a golden brass pin that looks almost golden.
"If Marikka could make something like this, the added value would be even higher."
"Oh, yes, that's right!
"I made a brooch this time, but the stone is so fragile that it would be better as an ornament rather than an accessory.
Seeing this, Emperor Hilde nodded her head.
"That's what I meant. < is huge. If we can add value that others cannot imitate, we can make it a specialty product.
Zion took this advice to heart and thanked him.
"Thank you, Jin. Thank you, Miss Hilde."
I'm not good at designing, so I'm asking you to take the lead on this one, Marikka.
Jin said, and Zion said with a smile, "Oh, that's okay.
"Oh, that's okay. Marikka is taking on apprentices right now and teaching them a lot of things. Some of them are good at design.
Apparently, Marikka is recognized as a leading expert in . He is somewhat proud of this.
Hearing this, Emperor Hilde said to Marikka
"If you are Marikka's disciple, then you must be Jin's granddisciple.
He said.
"Oh, so that's how it is, isn't it?
Jin nodded in agreement with Hilde's words.
"But a disciple. ...... You've grown up, Marikka.
When Jin heard that she was teaching a student, or rather a pupil, he was pleased to hear of Marikka's growth.
"Well, it's not much more than a hobby workshop yet,......."
Marikka blushes and says.
"We're just at the stage where we're making a few useful things while giving a little guidance to those who are willing to try.
In short, something like a <>, Jin imagined.
"Yes, but I think it's good to start with something like that."
Jin said, "It's impossible to teach advanced things from the beginning, and if Marikka's grow up, it will be easier to educate the younger generation.
"That may be so. ...... I will do my best to teach them."
Hearing this conversation, Emperor Taisho (Hilde) said to Jin: "Marikka-san, I'm sorry, but I'm not sure,
"Marikka-san, may I visit your workshop?
He said, "Marikka, would you allow me to visit your workshop? <.
"Yes, um, ......."
Marikka glanced at Zion, wondering what to say.
"It's okay, isn't it? If it's still just a hobby.
If this were a state-run factory, there would be important secrets and techniques that are not allowed out of doors, so it might not be easy to allow visitors to see the factory, but the current has just been born.
On the other hand, Marikka was reassured by Xion who said that she might be able to get advice from Jin and Emperor Taisho (Hilde),
"Yes, I will show you around.
Marikka was reassured and replied, "Yes, I will take you there.
So Jin, Hilde, Flora, Reiko, Sion, Marikka, and the five colored golem maids decided to go to Marikka's workshop together.
