The image of projected on the magic screen grew larger and larger.

And then they arrive at the surface of the island.

<

"I see... ...... means that there is a possibility that this one can be peeped at too."

Jin mutters.

"We need to quickly study the wards that can be deployed regardless of the underground.

He then turned his attention back to the image in front of him.

The image is of the surface of Onogoro Island.

"The vegetation looks very different. ......"

Goose says with interest.

"It looks like there are some small animals and insects that have evolved on their own.

Then the screen goes dark.

>.

The screen remained dark for about 10 seconds, and then suddenly changed.

There seems to be no light on.

Since the magical isotope (magi-isotope) emits weak magic waves, we are in night vision mode using it as a light source.

We cannot discern the colors, but we can see what is there.

"This is ......<, isn't it?"

There, along the wall, was a row of golems that seemed to be the <> he had once seen.

"Maybe it's a spare warehouse."

<>

The image moved to the side and went dark again. There must have been no room next to it. Then something appears again.

"Is it the material warehouse ......?"

"Looks like it. Is the important stuff a little lower?

The image went dark again. This time for about 15 seconds. And then.

"Is this ......?"

The room was in such a state of disrepair that it looked like a living facility.

"Dust accumulates even in the basement, I guess.

Even the furniture looks like it's deteriorating.

"Wouldn't it be strange if it was used by the originals?

Goose countered Jin's words.

"No, considering <> they lived here ......."

"Oh, I see."

I mean, how long has it been out of use? In other words, it must have been quite a long time since the < that supposedly lived here disappeared.

"It seems that the that created this place is no longer around, including the descendants of the .

"It seems that there are no documents left."

"But their lifestyle doesn't seem to have changed much from ours."

Vivian gave another impression.

The hierarchy of the rooms was full of residential areas, and they all looked the same, so we decided to go on to the next level.

The image went dark again for about 15 seconds, and then something was shown again.

"Hmmm, what is this?

Toa tilts his head.

"It's a strange shape. ......"

Stearina doesn't seem to understand either.

"...... Jin brother, what is this ......?"

But Erza seems to have realized what it is.

"Ah. It's probably an ether condenser.

It has the function of collecting and condensing free magical energy (ether) existing in space.

"What is different from the one I made is that it seems to have directionality."

The old man made a precise comment.

"But it's huge."

<

According to a rough comparison, the magi-machines seem to be about 10 meters high.

There are more than 10 of them in a row.

"Is this how they collect free magical elements (ether) ......"

The old man said that it would be so, considering the fact that the distribution of the free aether is almost unbiased.

Jin agreed with him.

"So there is such a facility underground?

"I see."

<

I see.

Jin thinks it might be possible to attack from the rear, but for now we need to investigate the facilities.

"What about other magic machines?"

This is the only Magi machine found on that level.

Then, we investigate a deeper level.

After a 30-second blackout, an image appeared on the screen.

"What is this ......?"

Jin had never seen a magi-machine before.

"If Jin-kun can't figure it out, we're at a loss. ......

Vivian gave up too soon.

"Can you see inside, old man?"

.

Only you can control it so precisely at such a distance.

The image came close to the magi-machine and passed through its outer covering.

"This is ......."

Jin, do you understand?

"It's partially ....... This is probably a device for transferring free magical element (ether).

But that was as far as Jin could go.

"The combination is complicated, and there are some aspects that can't be understood without seeing the actual thing. ......

"I see."

A black box is a device that can be used without knowing its inner workings, or a device that is sealed so that it cannot be seen.

Since it cannot be easily analyzed ......, it is possible that the itself, which created it, is using it without understanding it.

It means that modern Japanese who are familiar with PCs and smart phones do not necessarily know the internal structure of the system.

"I heard that <> also showed signs of degeneration, so ...... it's not unreasonable."

Jin, not knowing what he did not know, turned his attention back to the screen to get more information.
