<, the conclusion was that it was an unmanned magi-machine that monitors the distortion of the earth's crust.

"Now that we've seen what we need to see, and we've taken all the data, I wonder what we should do with ......."

Should we put it back where we found it?"

Erza gave her opinion to Jin, who was worried about what to do.

"If we put a marker on it, it will be easier to find it again, and we can do something like an underwater endurance test ......?　Or something like that?"

"That's an interesting idea. That's an interesting idea.

Jin decided to adopt Elsa's opinion.

He decides to put markers on the inside.

Just in case, four markers are prepared.

The is then sent back to its original location by , and that's it.

Of course, once the is sent out to sea, the will carry it into the ocean from there.

The first investigation is completed when the <> at the site reports that the sent < has returned to its original location.

What about the second one?

What about the second one?

<

A flat submarine 25 meters long and 25 meters wide. and a cylinder 5 meters in diameter and 20 meters long.

Since both of them were too big to be out of the transition magic circle of the cruiser <, a spaceship <> was urgently sent to transport them.

< is a special space ship with a diameter of 300 meters, most of which is propelled by the and the , which are also 300-meter class ships. It boasts 200 times the thrust of the 300-meter class <.

It was a piece of cake to transport the other two at the same time.

* * * * * * * * * * *

Two hours later, the <> returned just in time for the to finish her lunch.

"So, this is ......?"

<>

A flat submarine The flat submarine (?) is floating in Tatsumi Bay.

While it was being pulled up and brought in, the seawater that had accumulated inside was drained away, and as a result, it was able to float.

The submarine (?), which looks more like a huge hard capsule of medicine than a cylinder ...... was carried into the dock.

Both have been sterilized and secured, just like the < before it.

"Now, let's see which one we should start with. ......"

"Jin, why don't we split up and take a look?"

Not only Jin, but Reinhardt was also excited.

"That's a good idea. I'll go check out the capsule over here." "Okay, I'll go check out the capsule over here.

"Yes, I'll take a look at this triangle.

"I'll put ten of them on Reinhardt's support."

"Yeah, that'd be great."

I'll take Reiko and 2 craftsmen.

Jin, I'll go with you.

Then come with me, Erza.

I'll go with Reinhardt.

I'll go with Reinhardt. I think I'll go to Reinhardt's. It'll be more fun.

Okay, Goose, help me.

So Jin and the others split up.

Incidentally, Hanna is in contact with the <>s and is supporting the rear of Jin's group and Reinhardt's group so that reinforcements can be sent out at any time.

* * * *

Jin circles around the < placed on the dock.

It is now lying on its side, just like a large oil tank being transported by wagons.

Jin thinks that the contents must not be dangerous, since the old man is checking it with his <>.

"There's no place to open ...... this."

"If Jin can't find it, there's no way in or out, right?"

"So this is a sealed container. ......

"I see. Is there air inside?"

<

"Okay. Let's start with ......<>...... outer shell is a composite of light silver, adamantite and mithril."

The material is quite strong, Jin thinks to himself.

Then he uses again and takes three steps to the right.

"Okay, here it is. ......<>, please."

Jin instructed his assistant < to use his engineering magic to create a doorway.

"Yes, Master. ......<"

By engineering magic, an opening was made in the outer shell. The inside of the shell was indeed one atmosphere, and no air was blown out or sucked in.

However, the craftsman who had analyzed the air, <, warned us.

"Master, it looks like the inside was filled with nitrogen. Please wait a moment while I change the air.

"Oh, I see. ...... have they been storing something?"

When storing something for a long time, oxygen is removed and filled with nitrogen or carbon dioxide, so Jin thought that this <> might have been storing something, and he was right.

When all the air inside the <> was replaced by wind magic and it became breathable, <> reported to Jin.

"Master, the air inside is now breathable. Please come in."

"Oh, thank you."

"Father, I'll go first."

Reiko preceded Jin into the capsule, followed by Jin, Elsa, and <>.

Inside the capsule, there was one passageway running through the center of the capsule, and numerous small hatches of some kind were placed around it on the ...... floor and even on the ceiling.

And on them were written something in script.

"Hmm ...... is this some kind of ...... archive?"

Jin also learned from <> No. 700672, or halfway through <<>, so he knows the characters of <>. I can read the characters of <>.

No, to begin with, they are the prototype of the characters used by the human race of Arus, so they have a lot in common.

It seems that this <> was a .

"Father, there are letters here."

"Let's see... ......... ........."

After reading the text that Reiko had found, Jin understood that this <> was a kind of time capsule.

After all, it was a record of a part of <>'s culture and civilization, bequeathed to future generations.

"<> or ......"

Whoever can find the <> in the repository of the deep sea and pull it out. To such a person, this <......<> will be given.

The <> must be filled with the wisdom of the <>.

"Knowledge of <>. I am interested.

"Yes."

It is not a fragment, but a document compiled to be passed on to someone.

Both Jin and Erza are very interested in it.
