"Mermaid 1, Mermaid 2, well done. Reiko, thank you."

Jin works on the three. Then he looked at the warding generator that had been cut in half.

"Hmm, there is an energy storage section similar to a mana cylinder, isn't there?

Jin thought that it must have such a storage unit because the surrounding free magical energy (ether) and magical energy (mana) would be unavailable.

Then, when he tried to find out the principle of the warding, he found out the following.

The old man warned him.

"What?"

<.

Jin agrees with the old man's words.

"Yes, it seems so. But it could also be said that the other side has come out of the woodwork.

The only thing I am not happy about is that it is not that is on board now.

Edgar, I want you to head south as fast as you can.

Yes, sir.

Jin decided that he did not want to engage in a battle over the Shoro Empire.

First, he flew at the maximum speed for an airship. The wind is blowing from the north, so the speed is about 60 kilometers per hour. <

The three aircraft that are chasing us are going about the same speed.

"Could they be trying to find my base?"

<<

From Lake Tosmo it is less than 200 kilometers to the sea.

In a little over three hours, the was out to sea, where it slowed down a bit. The three aircraft that were in pursuit were clearly visible.

"It's a saucer ......."

But it was not the image of a UFO.

It is more like a shallow dish turned upside down, with the bottom of the thread facing upward.

Various kinds of magical devices seem to be installed at the bottom of the thread.

"<><>>...... Heh, that's an interesting method.

Jin examined the three disks, and found that they seem to be floating by the wind magic from below.

It was like a Frisbee, Jin thought, as if the parachutes were being levitated by the wind from below.

"In terms of speed, it may be equivalent to , which uses a ."

Jin thinks again about what to do from here.

"Okay, let's compare their performance. Edgar, the direction of flight is southeast. When you reach the equator, turn east.

"Yes, sir."

began to fly again at 60 kilometers per hour with the three disks following close behind.

Increase speed.

Yes, sir.

The first thing to do is to set up a wind shield. This will reduce air resistance and allow for a further increase in speed.

has increased its speed to 100 kilometers per hour.

"You're following ......."

The three disks also seem to be able to reach 100 kilometers per hour.

Okay, let's try to get them up to altitude.

"Yes, sir."

While maintaining its flying speed, <> gains altitude.

So far, the altitude had been about 100 meters, but soon it exceeded 1,000 meters, Soon it exceeded 1,000 meters, then 2,000 meters, then 3,000 meters, and so on.

"If you are using wind magic, the thinner the air, the less efficient it should be."

The same is true for Jin's .

The altitude had now exceeded 9,000 meters and was approaching 10,000 meters.

"With <>, 10,000 meters is the limit. ......"

This is the limit of buoyancy by helium. If this is <>, there is no limit to the altitude because it is designed for a spaceship.

< were fully inflated due to the low atmospheric pressure. The cabin is airtight.

"The propulsive force of the jet thrusters is also limited in this area.

But it seems that the same was true for the saucer, which was visibly losing speed and maneuverability.

"It seems that they too are at the limit of their wind magic."

Since there are similarities in principle, the limits seem to be about the same.

"Okay, okay. Edgar, that's enough. Reduce altitude to 500 meters.

"Yes, sir."

Now go to ...... Edgar, head to the South Pole.

Yes, sir.

is equipped with mana cylinders to deal with this incident, so it can operate even in Antarctica where there is no free magical element (ether).

But what about the three disks?　Jin decided to take advantage of that.

10°S,20°S.......

Free magic element (ether) is decreasing.

floats by the buoyancy of helium, so it does not consume mana. This is another advantage of Jin.

30 and 40 degrees south latitude.......

In the case of Arus, 1 degree is about 20 kilometers. 10 degrees is 200 kilometers. It is calculated to fly through 10 degrees in 2 hours.

Half a day has passed since the start of the chase, night has fallen, and morning has arrived.

"...... are you still following me?"

Jin, who had no intention to stay with us for more than 10 hours, had already returned to Horai Island by the warp gate on board.

Only Edgar, the pilot, and Jin's alter ego (doppelganger) are now aboard the .

Reiko, and Mermaid 1 and 2 had returned to Horai Island together, partly to lighten the aircraft.

I guess so. I was able to use that time to analyze this thing, though."

In front of Jin's eyes, there was a < warding generator that had been cut in two.

"Only a small part of it was destroyed when we cut it into pieces, and it was possible to reconstruct it.

Jin muttered to himself, "Thanks to Reiko, we were able to do this. Reiko smiled when she heard this.

"Brother Jin, please explain."

Erza, who was recording the analysis results, asked Jin to explain.

She could record the results but could not understand the principle at some points.

"Oh, sure. First of all, this is the first part.

Jin pointed to the record in Elsa's hand.

"The flow of magic control (magi sequence) here was new. In principle, it was a combination of , , and <>, as I had imagined, but it consisted of the flow of magic control (Magi Sequence) that combined them all together."

Jin explains, pointing to Elsa's record.

"Here is the magic formula (Magi Formula), and by using this value, we can speed up the process here."

"......Ah. The speed-up is transferred to us, and as a result, the efficiency is increased, right?

"That's what I mean."

It was a good lesson for me as well as for Jin. I can't think of any use for it, though.

The old man has good news.

"Oh, I see. That's good news."

And then...

<<>

<<>

Reinhardt and Saki also contacted Jin, and he was relieved to know that the crisis was over.

"Well, that's fortunate."

Jin turned his attention back to the three disks that were in pursuit of .
