The old man informs Jin who is piloting Jin D that he has found the "Supervisory Control Magic Brain".
<
"So that's where it's located."
Jin wonders if there was a deliberate intention to hide it, but he feels that < is a little off.
I don't intend to make a superiority or inferiority judgment about which one is superior and which one is inferior, since this may be an ethnic characteristic of the people.
"It is quite sturdy. I guess you could call it a shelter.
said <> in the middle of the digging work.
The room is about 10 meters long, 10 meters wide, and 5 meters high.
It was surrounded by solid walls.
"It looks like it... one meter thick stone, ten centimeter thick steel, one centimeter thick mithril, one millimeter thick adamantite..." he said. ...or..."
It has both physical and chemical durability as well as magical durability, indicating that they took great care to protect this magical brain.
But.
"...... in vain. ...... No, this was not enough."
The route to the room where the brain is located was secured, so Jin D got off too.
"A hole under the floor, huh?
A large hole had been made from the basement to this room.
The deterioration of the cross section suggested that it was more than 1,000 years old.
"It is probably ......1500 years old."
That would mean it was made before the time of Adriana Barbora Zetsi.
"I wonder what made the hole?"
Jin D muttered as he looked down at the hole.
The overall shape of the hole is a perfect circle. The diameter is about one meter.
Although the edges of the stone material were chipped and crumbling, the shape of the hole was very close to a circle.
I tried to find out where the hole led to,
.
The former hole could not be identified because it was not only collapsed and buried, but also assimilated with the surrounding soil and rocks.
It was the weight of 1,500 years.
"So, ......, it was destroyed by the person who made this hole."
Yes, the that was there was half-destroyed.
It is as if a part of it had melted away.
However, since it was 1,500 years ago, it was unlikely to be able to determine from its appearance what kind of attack it had suffered.
"For now, I think we should accept the fact that the <> is broken and make a plan for the future."
This is the soliloquy of Jin in Horai Island.
But the old man reacts.
"......."
<
"Yes, that's right.
<
"That's it."
I don't know how much is left, but the information on the <> is valuable.
"It would be nice to know why the <> was installed only in the <>."
* * * *
<> found in the basement of <> to the > and others, and left the control of Jin D to the old man, while Jin was holed up in his workshop.
With Reiko as his assistant, he is testing a prototype of the magnesium-based alloy that he learned from the analysis of the the other day.
"Magnesium-based alloys seem to have poor heat resistance, so we haven't used them much, have we?"
< on fire?
In air, magnesium burns violently with a flash. This was used in the < used in cameras in the past (now replaced by strobes and LED lights).
In short, it is easily oxidized, and this is the reason why it is sensitive to heat.
However, <> was stabilized by using magi-based materials, and its hardness, toughness, and melting point were increased.
The strength of the material is low unless it is strengthened by magic power.
"Can't we increase the strength semi-permanently by mixing magecrystal powder here ......?"
Yes, what Jin is aiming for is a material that surpasses the material of the .
However, things do not go so easily.
"......It's impossible after all. ......"
Metals and magi crystals are incompatible and do not mix as they are. Or rather, they do not form an alloy.
"<> is not possible?
Since the original physical and chemical properties of magi crystals are such that they are incompatible with each other, it was not possible to try to alloy them by force.
"Then there's also the powder alloy, but it's ...... less tough. ...... hmmm."
For a while, Jin thought about it.
Then Saki came over.
"Kuhu, Jin, you seem to be working on something interesting.
"Ah, Saki. Just what I need.
Yeah, what's that?
"Yeah, what's up?" "Actually, ......"
Jin explained to Saki the concept of the material he was aiming for.
"I see. It will certainly be wonderful when it's finished."
"If we're going to make it, I'd like it to surpass the originals."
"I guess so."
Jin then proceeded to research the new material while asking Saki for ideas.
"In short, you want to make it so that it is always in a state of magical power enhancement, right?"
"That's right."
"But wouldn't that make it difficult to process? I'm sure gin can do it."
"Oh, ...... I see."
Jin reflected, "That was a blind spot.
"Then, should we make it possible to increase the strength by <> after ...... processing? I think it would be the same as applying <."
"Kuhu, that's the problem I'm having."
"Let's think about it some more. ......
Then, the old man contacted me.
< at the site of Jigosaldo. He says that he has finished extracting information from the general control magic brain.
"Oh, I see. I'm on my way."
Jin headed for the cafeteria, thinking it would be a nice change of pace.
As he hurried to the mess hall, Jin was thinking that since this room is used more than the command center these days, he should do some more maintenance.
* * * * * *
All the members of the were gathered in the dining room.
The old man started to summarize the information he had obtained.
