"Under the floor of the command center is the machine room. < and other important Magi machines."
"Can you move it in case of emergency?"
"Of course it can. <, it might be better to use it in case of danger."
< is a magical tool that replicates the magic used by the and can transfer itself.
However, the distance to be transferred is not very great. At most, it is a few kilometers.
"It is designed to be able to shift 500 meters to 2 kilometers above the surface, so it should be able to shift the distance to the sea surface depending on where it is placed."
"I see. That's just like Jin, isn't it?
"We also have a transporter, so we can use it to escape. In that case, the base will be obliterated by a mana explosion.
"I see, so as not to fall into the hands of <>. I don't know if there is such an enemy.
Reinhardt said with a slight frown.
I don't know if we have any enemies like that. We have ...... some weapons, though."
Jin then began to explain about the defensive weapons.
"First of all, we have a that can withstand water pressure of 10,000 meters.
"Yes, yes."
"The first stage of the attack ...... is a ."
Yeah, it's gonna be pretty messed up if we hit it with a lot of light in the dark depths of the ocean.
"Hmm, I think it would also damage the eyes."
"And then we can cast a spell on them. Or even Absolute Zero if the need arises.
"Is the cooling system effective ...... because we are underwater?"
"Well, I don't think it's possible to not freeze at minus 70 degrees Celsius."
Guth wondered about the effectiveness of the cooling system, and Reinhard affirmed.
"And and ."
"Sound and electricity. Sounds effective."
"Are there no material means of attack?"
Goose agreed, but Saki voiced her doubts.
Jin answered: .......
"Well, we didn't want to make any openings other than the airlock, so we couldn't even make torpedo launchers.
"Then, why don't you prepare some kind of missile pod that can be remotely controlled? Or maybe an external one."
"Yeah, that's a good idea."
Hannah explained her idea.
Jin agreed that it would certainly be no problem if it were externally mounted.
"We could have a weapon like an underwater gun. We could use a force field generator to fire it.
Bertsch was in the middle of this when Jin said,
"Mr. Jin, please show us the living facilities.
She was told that she had to talk about armaments. She was a little bored with the discussion about armaments.
"Oh, sure. I'm ...... sorry."
Jin sensed this and readily agreed, apologizing.

"The living quarters, though, are simple because I don't expect to spend many days here," he said.
The machine room is located directly below the command center, and the living quarters are further below that.
If it were placed at the bottom of the ocean, it would be buried underground.
"The capacity is for six people. There are beds, chairs, and a table. It is a bedroom and a living room. We have separate rooms for men and women.
The room is for 3 men and 3 women, for a total of 6 people.
The room is about 6 tatami mats in size, so each person has a space of 2 tatami mats.
The kitchen was equipped with a stove, microwave, and other cooking utensils heated by magic.
"There are 10,000 liters of water in a tank that also serves as ballast.
A typical oil drum holds 200 liters, which is equivalent to 50 drums.
Apart from that, fresh water could be made from seawater.
"The food supply was mainly preserved food for 10 days."
Replenishment is done at the .
"Of course, you can return to Horai Island by using the Warp Gate, which is not for escape, and you can also keep in touch with each other by using the Manacam.
So you don't have to sleep and wake up here, and you can have your meals on Horai Island.
Water, food, baths, and beds are only for insurance purposes, and were provided because they are functional.
We have air purifiers and air conditioners."
This is a technology developed in submarines and spacecraft.
"...... is this what I think it is?"
"Thank you very much, Mr. Jin. I understand now.
Bertsche agreed and thanked Jin.
Jin continued.
"In addition, we also have a maintenance room for the mariners who will be staying here, and a waiting room for the mermaid squad.
Since the mermaid squads are mermaid-shaped, they have their own waiting room.
"There are also two other reasons to set up this base ....... One is as an antenna base to build a on Arus.
The other is to secure the resources on the seabed, Jin said.
Jin has other reasons for storing materials than for his own use.
In the distant future, when the resources of Ars are depleted as they are in Hale, and human technology has not yet advanced into space.
The old man is storing it for such a time.
The old man, Erza, ...... and all the members of the Jin family were aware of this fact.
By the way, the storage places are dispersed in Horai Island, Yunyi, and Hale.
And Marikka was also stockpiling resources in the same way in <>, though on a smaller scale.

"All we need to do now is to do a pressure test and we will be ready to install them."
The pressure resistance test is conducted in a water-filled compression boundary.
Compared to molecular compression of adamantite, it is easy to create water pressure equivalent to 10,000 meters in depth.
In front of the eyes of the entire on Horai Island, the <> had withstood a water pressure equivalent to 3,000 meters.
"Okay, let's build three more just like it.
Jin said, "Okay, let's build three of these same ones for now, and install them wherever we think best.
"Yeah, this is going to be fun. Let's see what kind of resources we can get.
"I'd like to go out and play with them once they're installed.
I'd like to use it to survey the seafloor.
Saki, Reinhard, and Goose are looking forward to the installation.
"I'll finish the installation tomorrow."
"Kuhu, I'm looking forward to it."
And then Hannah said,
"Hey, honey, are you going to name the base? Or do you call it or ?"
I said.
"Hmmm, let's see ......, why don't we just use numbers instead of names this time? Basically, we're fixing it, not moving it."
"I see."
And so the preparations for the installation of the <> proceeded.
