The lively voices of the are echoing in Horai Island.
"By the way, Jin said he was going to build a canal. How big do you have in mind?"
Jin replies to Goose's question.
"I'm thinking of something large enough for our battleships, but not so large that a cruiser can pass through it.
"A cruiser. ...... So the channel would be about 30 meters wide and 10 meters deep?"
"Yes, I think I'd like it to be a little wider.
Some time ago, Jin is building a canal in the Principality of Norway.
At that time, he had 100 craftsmen work on it, and it was 3 meters wide and 1 meter deep with a total length of 20 kilometers. It took only 3 days to complete the 3 meters wide, 1 meter deep, and 20 kilometers long.
From that, if 100 were deployed, a canal of the same width and depth would be 80 km, which is 4 times as long as a canal of the same width and depth. 12 days.
The depth is 10 times deeper and the width is slightly less than 17 times wider, so 17 times 12 days. 2040 days = 68 months = 5 years and 8 months. If the efficiency is increased by a factor of 10, it would be 204 days.
It was thought that if the efficiency was increased by a factor of 10, it would only take 204 days, and the construction period could be further shortened by increasing the number of craftsmen (Smith).
"Well, if we can do it in a year, that's good enough.
"It's still amazingly fast, but it's still a big deal. ......
Hanna said, "Normally, a project this big would take a lot of people and ten years to finish.
"It would be faster if we use Daidara ...... Oh, if we use <> to gouge out the ground with <>. ......"
"I don't think we should."
Erza calmed Jin, whose thoughts were escalating.
"Is that what you think?"
"Well, no matter how quickly you want to finish it, you can't expose to the public."
"I understand. I'm just saying.
After such an exchange, Jin spoke of his rough plan.
"It is known that the Duchy of Norway used 100 , so we will use 200 this time. The channel will be 50 meters wide and 10 meters deep. The construction period is expected to be 150 days.
"Yeah, that's about right if Jin is going to do it."
Reinhard nodded. He said that everything should be done in moderation.
"...... what did you mean by moderation?"
No one responded to Bertsche's mutterings. .......

After that, he surveyed the rest of the .
"Hmmm......... there's no more material of interest."
"I guess so..."
"No more here, either."
The material here is really quite elementary.
"...... so do they also have an intermediate level repository?"
"What?"
At Goose's muttering, the people who had been examining the vaults turned around.
"No, if we want to preserve the knowledge for future generations, I thought it would be good to have not only the beginner level but also the intermediate and advanced levels."
"That's right."
So there are others in the sea?
"I don't know about that. ......"
He completely stopped his research and went into a chatting mode.
"It's hard to imagine, since the way of thinking of <> is a little different from ours, but I wonder if they would hide it in a similar place..."
Goose goes on to share his thoughts.
In other words, <> is an easy place to find. is a little more difficult to find. > is even more difficult to find. ......
"...... is it easier to find in deep water ......?"
"I guess that's where the < is. ......"
"Then, is the intermediate level hidden in a more difficult place to find?"
Then Saki called out to him. She was alone, looking through the materials without stopping.
"Hey, I found something interesting.
"What? What?
"Here, this."
Saki was holding a book with a black cover.
All the previous documents had been inscribed on a .
I am late in explaining, but this or is a synthetic resin-like plate about the size of A4 and about 3 mm thick, with small magical crystals (magicrystals) embedded in it for recording information.
The plate contained a brief description of the information.
The plate is an A4-size IC card, with a magi-crystal embedded in it instead of an IC chip.
Instead of an IC chip, a magical crystal (magi crystal) is embedded in it. The card was kept on a shelf together with the .
Jin and the others rushed to Saki's side, finding this interesting.
"I'm curious about the book that <> was reading. I've been meaning to open it with Jin and the others, but I haven't looked inside yet either.
So all of us transferred back to the institute's cafeteria and decided to open the book.
"I don't see anything on the cover."
"Yes, it's a dark black cover made of a leather-like material.
"Then I'll open it.
Saki said in a light tone and opened the cover first.
"......"
"......" "There's nothing on it."
"Then I'll open another one.
"......Well, <>?"
"<>?"
A natural history is a book that describes all kinds of knowledge, and several books of the same name have been written on Earth.
It generally means <>.
"Most of them are about the creatures that were in Hale. ......"
"I've never seen these creatures before. ......"
However, the basic structure of plants and animals has not changed.
Guth, originally a naturalist, was most interested.
"That could be useful in the redevelopment of Hale."
"Oh, yes. I think it would help to make the vegetation as similar as possible, or to plant closely related species ......."
"Animals and insects are harder."
"I don't have a choice. ......
The other members of the <>, who are engaged in the redevelopment or redevelopment of Hale, were interested in helping to some extent.
* * *
And .......
"In the end, the harvest is a hint to increase the efficiency of earth magic and a natural history ......."
"Kuhuh, that's what I thought."
Although Jin and the others were a little disappointed, they decided not to be extravagant as it was an unexpected find.
"So, after we make copies of the documents, I think we should put the <> back in its original place.
"Yes, that would be fine."
"No objections."
No one objected to Jin's proposal.
Jin then continued,
"So, I'd like to show this to the rest of the Jin family, as well as to the elders who are currently in Hale.
"Yeah, that might be a good idea."
"Yes."
This opinion was also accepted by everyone.
Jin then decides to contact the remaining members of the and the .
