"But Elsa is amazing."

What?

You developed an ether analyzer.

That's not true. Brother Jin is much, much more amazing."

"Well, I don't know if that's true. ......"

Jin considers himself neither a researcher nor an inventor, but an engineer.

What he has created so far is mostly a combination of the knowledge he has inherited from his predecessors and the scientific knowledge he has learned in modern Japan.

The things that I have created so far are mostly a combination of these things.

"Maybe so, but isn't everyone like that? But I think everyone is like that."

Erza affirmed Jin's thoughts, but also criticized them.

"No one can make something out of nothing. I think that everyone makes things by referring to something, learning from someone else, and combining various things. It's just a little bit of their own ingenuity.

"I guess that's how it is."

"I think so. But I think it's great that Jin brother is not conceited like that.

Jin smiled shyly at these words.

"Thank you, but please don't flatter me. But please don't flatter me."

While exchanging such conversation, Jin and Erza made a new <.

The first prototype was a second machine that could cover the whole area of Horai Island.

If it succeeds, they plan to build one that can cover the whole of Ars.

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

"Well, this explains a lot..."

"Hmm."

Jin and Erza discuss while looking at the screen of the second prototype.

The flow of free magical element (ether) in Horai Island is visualized on the screen.

Of course, the movement is in the same plane,

As the old man said, "I would like to leave the 3-dimensional <> to you," Jin thought.

"But really, this Horai Island is a singularity, isn't it?"

In the screen, free magical element (ether) seems to be gushing out from the top of Mt.

Also, a small amount of free magical element (ether) is gushing from the ground of Horai Island.

"That's why they are the Grand Spider and the Grand Caterpillar.

These two types of demons live only on free magical element (ether). They are gentle in nature, and the threads they spit out are a rare material unique to Horai Island.

"Perhaps the underground resources are abundant..."

"Perhaps."

Based on this success, Jin and his team finally decided to build a large scale <.

* * * * * * * * *

November 4th, the day to test the large-sized "Aether Analyzer" installed in the basement of Horai Island, which took a whole day.

"Okay."

That's what I want to know now.

What is the distribution of free magical elements (ether) in Ars and its surroundings.

This will also help us find out what <> is doing.

Jin, this line has been checked.

"Father, the Magi Reactor has been activated."

Okay, start scanning the area around Ars.

And 1 minute.

This time, the scanning results can be displayed in pseudo 3D under the control of the "Mere Old Man", so that Jin and the others can easily understand the results.

In front of Jin, Elsa and Reiko, the movement of free magical elements (ether) in Ars and its surrounding space was displayed.

"I see. ......"

From Ars and its surroundings, free magical elements (ether) converge and flow toward the top of <>.

"So this is how it flows. It is true that there is less free magical element (ether) on the surface of the earth."

The image is like a high-pressure system and a low-pressure system. If we were to superimpose rain clouds and precipitation images on them, it would be a little closer.

< is a super high-pressure system. And there were two more super highs as well.

Or perhaps the visualized geomagnetic field is closer.

"Now we know where the facility that collects the free magical element (ether) is located."

on was hidden, but this makes it obvious.

But there was a more disturbing trend.

"What is this?　What is this? ......"

There is a slight shimmering in Antarctica, where there should be nothing.

"<> said there was nothing, but that doesn't mean it's true, does it?"

There are no continents in the Arctic and Antarctic of Ars, both are oceans.

Deep below the surface of the Antarctic Ocean, we could see fluctuations in the free magical element (ether) that made us think that there might be something there.

"But according to the investigation by the Mermaid team, there was nothing on the sea floor."

.

"fumu......"

.

"Oh, yeah. ......!"

It was the seafloor that was surveyed at that time. The sea floor at the Pole is difficult to see from the observation satellites, so if there is something a few dozen meters below the sea surface, there is a possibility that we may miss it, the old man guessed.

"Indeed."

Jin agreed with his guess.

"I said that I would not set up in an unstable and uncertain place. ......"

Elsa also made a guess.

This was an assumption based on the fact that they had recently installed a measuring device in the underground of Horai Island.

"Brother Jin, or if it was not on the sea floor, but further under the sea floor: ......"

"I see!　That would make sense."

The old man agreed with Elsa's guess.

"We'll find out soon enough, won't we?"

<

Free magic element (ether) is not affected by ordinary objects. It penetrates rocks as if they were nothing.

"I knew it. Elsa, that's great!"

"...... by chance."

Erza, embarrassed by Jin's praise, turns her head down, her cheeks tinted.

"But then,...... I think the depth of the Antarctic is about 2,000 meters, right?"

"Then we would have to use a submarine, but even then, we can't just dive further beneath the ocean floor, can we? ......

Erza asked Jin as he thought about it.

"Brother Jin, is it possible that there is a way in or out somewhere?"

"Well, it's ...... rather possible that they could go in and out by transitioning. ....... Worst case scenario is that it's just left there after installation."

<>

"Yes, I guess so. ...... indeed."

I will consider the old man's advice.

Certainly, going to the device in the Antarctic is not going to do anything.

"It's not like we're going to break it. ......"

At that moment, Erza looked at the screen and shouted.

"Brother Jin, look at this."
