On the morning of July 20th, the old man reported to Jin.
"An interesting discovery?"
.
"Wow. That's great!
500 years ago is a time that has remained a mystery until now.
Jin was disappointed to hear that.
"That's a real shame. Nothing happened there?"
"<>?"
<
"Lukor? I think I heard it somewhere: ......"
"Father, he is the researcher we met at the Keowan site."
"Oh, that guy from the Giggarth Riots."
I remember that he claimed to be an archaeologist.
"I thought he had been gone for some time, but I guess we had a connection in some strange way.
"That's right."
Jin and Reiko nodded at each other.
"But I'd like to check out a 500 year old research facility or ...... even if the materials have been scattered."
"Oh, you're the man, old man."
Jin hoped that this would bring some information.
<
"Yes, what is it?"
<
The activities of the Nostalgia Party are free as long as they do not conflict with the policies of Horai Island.
The old man will organize them and report to Jin when the time is right.
Please take care of them.
"I see, so you are supporting such rural areas?"
<<
"I see. What are the specifics?"
Especially sewage treatment and the dispatch and training of healers.
<<><> are put into a permeation tank.
This method was invented by Jin. When the < is no longer effective, it is time to replace it with a new one.
Since Jin's assets are increasing, he also donates to these shadow public projects.
However, even without that, the Nostalgia Party had tremendous amount of assets during the time of its predecessor, the Unification Party (Unifiler), and they were engaged in these activities to give back to the society.
"That's good to hear."

"We didn't get much out of it. ......"
"Mm."
Vivian and Lecorre met up with Zidane at his hut and then headed down to the town of Nikalai.
When they returned to the inn, the two helpers had already returned and went back to their rooms, telling them that they had not gotten anything out of it.
"...... I don't feel much motivation."
Vivienne said as she watched them walk away, and Lukor nodded his head in agreement.
"Yes. But, well, I wouldn't be so angry if they were really just ."
"I see what you mean.
"I'm just curious about this sentence. Zidane would have read it."
Vivienne looked once more at the leather paper that she and Lecole had written down.
"<>......<>, doesn't it?"
A few words were unreadable, but the completion was easy.
"But how is that possible? What are we making up in the first place? ...... I'm an archaeologist, so I don't know, but Zidane seemed to be on to something."
"I know a magecraftsman, so I'll ask him next time I see him.
"Yes, please do. Anyway, I am sure that this sentence is about some past technology.

The contents of the letter were brought to Jin later that night.
Jin heard it in the control room in the basement of the institute together with Erza.
"Erza, what do you think?
"<>...... honestly, the only thing that comes to mind is ......."
Elsa glanced at Edgar, who stood beside her.
With this gesture, Jin sensed that Elsa had the same perception as he did.
"Automata, or golem, right ......?"
"Hmm."
Reiko, for example, has muscles, skin, and hair as biological materials.
Skeleton, eyes, nerve lines, control core, etc. are mineral materials.
"Why do you use biological materials in the first place?
Erza asked a natural question.
However, Jin does not have a clear answer to this question.
"For one thing, because they are excellent ......."
Ancient dragon shells used for Reiko's skin.
Synthetic materials are not even close.
"But it's hard to find."
Elsa mentioned the drawback. The memory of wandering around in the snow on the northern continent in the extreme cold with is still vivid.
"Yes, it's good for one-off productions like ...... Reiko, but it's not suitable for mass production."
"Father, but I remember that in my early days, my skin, hair, and muscles were made from the threads of a ground spider.
That's right, the initial materials were made from the threads of the ground spider, magically processed and synthesized.
"Indeed. < and were fixed using synthetics.
Although they are synthetics, they are not synthesized from nothing. There is still the original material. In the case of Horai Island, it was the threads of the .
"Even plastic is made from petroleum and coal. Organic materials are often superior.
Even complex chemicals are produced by microorganisms.
Some people may have an image of fragility when it comes to biomaterials, but that is exactly what they are, from one end of the spectrum to the other.
However.
"But, the underground spider (ground spider) is not a monster that you can find anywhere. ......"
The ground spiders in the underground of Horai Island seem to be an exceptionally superior species," Jin concluded.
"That's why they try to use mineral systems? But ......"
"I understand what you mean, Erza. There are many rare mineral materials like adamantite.
In short, there are pros and cons, Jin summarized the discussion.
"But if something new is discovered, we may never know."
Later than the previous generation, before the Magic War.
What was developed and disappeared in such a short period of time?
