> concluded so.

Since it was an urgent matter, Jin, Erza, Saki, and Goose settled the matter together.

After that, as usual, he went on with his own hobby.

The old man decided to have a few sets made for himself for recording purposes, and it was immediately realized.

And then, he asked the old man to make a few sets for his own records, which was done immediately.

And then....

"This is the damage caused by : ......"

The old man, who had prepared several sets of specimens of the grasshoppers, iron rods with gnaw marks on them, and <> of the damage, sent them to major countries in the name of Jin.

"They eat iron too? ......"

"You eat every last blade of grass. ......"

When the leaders of the nations saw this, they trembled. At the same time, they were also relieved to see Jin's annihilation.

"Indeed, I can see why the <> is necessary."

In the Shoro Imperial Kingdom, the sense that the damage had been contained was exceptionally strong, and the female emperor let out a sigh when she saw the report.

"If Jin-kun's response had been a few days later,...... no, it's a miracle that you noticed it before that."

Jin happened to be on an errand to the north of Mitsuho.

The purpose of his visit was to develop a method of recording the attached <>.

"<>...... is a true capture of the truth, isn't it? It's a wonderful magical tool."

You're right, Your Majesty.

Jin-kun says it's still under development. I hope he'll sell it to our country when he's finished.

"Yes. There are many ways to use it. It is a little small for ...... instead of a portrait.

I'm sure Jin-kun can handle that too.

"Perhaps..."

The emperor and the prime minister had complete confidence in Jin, a rare engineer, a magical engineer "Magi Craft Meister".

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

"Hmmm, <> or ......."

In the Kingdom of Celuloa, King Cesar was looking at the documents he had received with a difficult expression on his face.

At the end of his desk, Mr. Lambreaux, Secretary of the First Ministry of the Interior, is looking over the materials handed to him by the King.

"I thought I found it in the records about 150 years ago," he said.

"Yes, I believe so.

After reading the documents, Lambreaux got up from his seat and went to the reference room adjacent to his office.

A few minutes later, he came back with a record in his hand.

"Your Majesty, it says here that in the year 3310, a quarter of the land was destroyed by a swarm of insects that came from the north.

Is this the same thing?

Is this the same thing?　I'm comparing the illustration to this photo, and it looks like the same thing.

"Yes. But this is a marvelous thing."

"Truly. It will be of great help in keeping records."

"Korun says he'll distribute them to our country when they're finished. I'm looking forward to it.

Yes, sir.

"So, going back to the matter at hand, I heard that the grasshopper was exterminated by the Korlun-kun, and I hope that in the future the World Guard will be able to take on such a role.

"To that end, ......"

* * *

"<>. What a scary bugger.

Your Majesty.

Even in the Kingdom of Klein.

"<>" is a ....... I've only heard of them in the records, but they're real?

Yes, and if these pictures are true, they are a threat.

"But since it was vanquished by the Kun Lun, we can rest easy for a start."

In the Kingdom of Egelea, too.

And in the kingdoms of Franz and Elias, the threat of the was accepted with reality.

At the same time, the fact that Jin exterminated them.

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

"<> has exterminated the <>!"

"Hurray!"

Everyone in Mitsuho was praising Jin's achievement upon receiving the news that the Magecraft Meister had defeated the ravenous grasshoppers.

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

The old man was indeed stunned by the amount of grasshoppers he collected from the exterminated ones.

100,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000.

Grasshoppers that take in free magic element (ether) mature and reproduce rapidly.

Moreover, as long as they have free magic element (ether), they can grow without organic matter from the second generation onward, just like other demons.

"Yeah, I didn't think it would go this far either."

Goose helped me with my research on the ecology of the <>, and this is the result.

"Ordinary grasshoppers mutate in areas with a high concentration of free magic element (ether), and from the second generation onward, they multiply only with free magic element (ether) and eventually head for other areas."

<<

This is a question that even the "Mere Old Man" could not have guessed.

"Yes, I have a hypothesis about that."

.

"Yes. "......1 the concentration of free magical elements (ether) per animal."

With that, the old man knew what Goose was talking about.

<

"Yes. And they are insects, too. They seem to be weak against the cold, so they probably go south instead of going north where the free ether is thicker.

<<

"Well, that's my theory."

"Now if we could only identify the point where the concentration of free magical element (ether) is high.

<<>.

"I guess. So there's no point in looking for them now."

Goose nodded to <, his bodyguard and driver in place of the old man.

<

"Yes. I've had enough of the sky."

<

"Not this time, anyway."

Goose uses the warp gate of the he landed on to return to Horai Island.

The empty wilderness was just the wind blowing.
