When Jin and the others were thinking about the right way to fit them in, the <> gave them some advice.

"According to the way the <> think, you should be careful because you never know what will happen if you try to fit it in the wrong way.

< could be ruined, he said.

"Thank you very much. I will be careful. ......"

That was all Jin could say.

"...... Well, if you could think of something, I think you would have thought of it by now."

"Yeah, I guess Jin is right. That means that in addition to the <>, there is a clue hidden somewhere."

"Well, brother Rai's opinion is logical. I think you are right.

So, in search of clues, the members of the Jin family began to search once more in the vaults.

Meanwhile, Licia alone began to explore the empty cube-shaped room they had found.

"There is a possibility that there is a clue in this room, isn't there?

"Yes, it is very possible. You are very good to notice, Licia.

< also praised her judgment.

"Thank you, my lord. I will do my best to find it!

Licia was elated.

And her efforts are rewarded.

There was a further hidden lid on the floor, which, when opened, showed a diagram of where to fit the four walls.

"There it is!　There it is!"

"What?

Licia, how did you find it?

"No, no, it was just a coincidence. But I'm glad I could be of help."

Licia seemed happy to be praised like that.

* * * * * * * * * * * * * * *

"I see... <<2-4-2>> means that here on the second shelf, fourth from the left, second from the top, is the <>. The second is to be inserted on the second shelf from the fourth from the left.

In the same way, fit the other side.

And I fitted four of them. .......

"Nothing is happening."

"It's not happening. ......"

"Maybe there is some trigger to activate it?"

So, the members of the group are thinking about how to move forward.

As expected, could not give any more hints, and we were almost at an impasse.

"Why don't you try closing the top lid?

Reiko suggested.

"Well, there is a strong possibility that closing the lid will activate it.

< also suggested this idea, so Reiko, who was the one who had initiated the idea and was the most capable of dealing with any problem, stayed inside.

"Reiko, let's close the lid."

"Yes, father, anytime."

"Okay."

Jin closed the lid at once. He waits for a minute, but he doesn't hear anything from Reiko, so he opens the lid and sees .......

"Reiko!

She's gone!

Reiko had disappeared from the room.

"Yes, let's ask the old man to check Reiko's reaction!

As Jin hurriedly tried to contact the old man, a magic circle appeared on the floor of the room and Reiko appeared.

"Reiko!　What the hell happened to you?"

Jin jumps down into the room, grabs Reiko by the shoulder and asks her.

"I'm sorry for worrying you. This room was a warp gate. It was activated when the lid was closed.

"I see. ....... Was that a possibility at ......?"

"Yes. Yes. I was transferred to a place where there are many similar materials to this one. The pressure was low, so it was probably on top of a mountain.

According to Reiko's report, the place where she was transferred was probably a high mountain, where the documents were stored.

As expected, she stayed there only for a short time, so we do not know much more than that.

Therefore, we ask Reiko to transfer again. The old man will take a with him so that he can easily detect the location.

Of course, Reiko's own magical reaction can detect the location, but it would be faster to use the special marker.

"Then, I'll be on my way."

"Please."

Reiko moved again.

Twenty seconds later, the old man reported.

"North of the village of Kayna. ...... Oh, that mountain."

This is a glacier-crested mountain that can be seen from the village of Kayna, as well as Nido Castle. The elevation is probably over 5000 meters above sea level.

It is said that there is a second vault in the mountains.

"All right, let's get ready and go exploring.

Reiko will check on safety, while we make preparations for ......, but we have bracelets for protection and communication, so we only need to prepare emergency for all of us.

The destination is set to the village of Kaina ...... and the castle of Nido.

And some water and food.

"Oh, yes."

Accompanying us are 10 smiths.

Since I was somewhat worried that the <'s <> would not be enough, I decided to install one made in Horai Island as well.

"Is this all the preparation you need?"

"Yes, I think so.

It takes about 15 minutes to get ready.

Reiko came back just in time.

"Father, I'm back. There is no danger at all. The air pressure is a little low, but the air is breathable. But the temperature is a little low. About 10 degrees Celsius.

"I see, that's fine."

Jin is not a cold person by nature, and the other homunculus members are also not affected by such temperatures.

As for the atmospheric pressure, even though <> is over 5,000 meters above sea level, it is still unclear if the inside is somewhat pressurized or if there is a <> at a lower location, but it is estimated to be approximately 800 hectopascals. It is said to be about 800 hectopascals.

This corresponds to an altitude of about 2,000 to 2,100 meters.

Jin and the others decided that they would not suffer from altitude sickness at that altitude.

"Okay, let's go then.

"Yes!

<

The four non-researchers, Meine, Martha, Bertsch, and Milowina, are to remain on Horai Island.

First, Jin, Reiko, Reinhard, and Erza moved to the island. Following them, four people moved to the island one by one.

Neige, Rouge, and the are the last to be transferred.

Incidentally, the room's was operated by 800 of the remaining group.

* * * * * * * * *

"So this is the second <>. ......

"It looks spacious."

The first group of people who entered the vault, including Jin, Reiko, Reinhardt, and Erza, left not through a hollowed-out room, but through a clearly recognizable warp gate.

"Let's make room for the next group."

"Oh, yes."

Following Reinhardt's words, the four quickly exit the warp gate.

The next four ...... Hannah, Saki, Goose, and Vivienne appear.

"Kuhu, this is the second ...... interesting."

And then one by one, the members of the arrived.

Finally, Neige, Rouge, and the <> arrive.

At about the same time, 810 people from 801 arrived by .

This means that all the members of the survey team are now present.

"Okay, let's start the survey!

Finally, the investigation of the in <> begins.
