On August 5, Jin was visiting the Principality of Norway to provide technical assistance.

"<> Jin, welcome to the Duchy of Norja.

The Duke of Norway, Keith Tennick de Norha himself, welcomes Jin's .

"Thank you for coming."

This time, Jin himself is here. He is accompanied by Reiko and piloted by Hope.

< has a remote control mode, so it is safe even if it is unmanned.

Therefore, Reiko and Hope head for the castle with Jin.

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

Jin is shown to a small conference room at the castle.

In attendance are the High King Keith Tennick de Norha, the Prime Minister Premus Hai Yasna, the Minister of Industry Daha Shomur, the Minister of General Affairs Kaim Lo Hasta, the Minister of Magic Mico Bee Safran, the Minister of Technology Jarvie Keefe, and others.

"First of all, I have something to report.

Prime Minister Premus High Yasna began.

"The other day, we received a report on the results of the soil test from Avalon.

"Is that so?"

"According to the report, the normal soil is composed of sand, clay, humus, etc., and it seems that the soil here is no different in this respect.

But only , not really.

"Sand ...... is mineral particles. The original mineral was a magi stone.

"I see, that's amazing!"

Jin knew this from the analysis of Saki and the others, but he showed his surprise at this moment.

"It seems that this magistone ingredient has revitalized the soil, and that's why we've been getting a continuous good harvest.

"Is that what you mean?"

Jin thought he should add one last point.

"Hmmm... ......"

First, he looked thoughtful.

"Jin-dono, what is it?"

Sure enough, the magic minister Miko Bee Saffron asked,

"Yes, I have one thing on my mind.

I reply.

"What is it?"

"......<> activates the soil, but I think there must be a <> somewhere for that."

"Master?"

Daha Shomur, the Minister of Industry, asked back, as if he didn't understand the way I said this.

Yes, I mean a master slave in the chain of command. In other words, there must be a magical tool or a magical machine (magi-machine) somewhere that corresponds to the master who gives orders.

"I see. ......"

"I see. ......"

Magician Miko B. Safran and Technical Minister Jarvie Keefe immediately understood the meaning of Jin's words and seemed to agree with them.

"What do you mean?"

"Please elaborate."

But the Prime Minister and the Minister of Internal Affairs and Communications still didn't seem to understand, so Hitoshi explained further.

"In other words, it is possible that there is a magical tool buried somewhere that issues orders such as ......<> or >."

Now he finally understood.

"Oh, so that's what you mean!"

Jin followed up further.

"However, we brought back soil samples for analysis, so it's not surprising that we don't know. It's not that 's analysis technology is poor.

Jin added that he was able to notice this because he was on site.

"That's why I'd like to find out where the is."

< is an important issue for the Duchy of Norway, Jin wanted to finish this series of investigations.

"Yes, I would like that very much."

Keith Tennick de Norha, who had been listening in silence, opened his mouth and bowed lightly to Jin.

Jin was surprised, to say the least. But he thought that this was another way of showing the sincerity of the Duke of Norway,

I understand. I will do my best.

He replied, "I will do my best.

I will do my best.

So, soon after that, Jin headed for the farmland in the on board the .

The pilot was Hope, accompanied by Reiko. Accompanying him on board is his magic minister, Miko Bee Saffron.

"We have a limited amount of time, so we're only going to stop at a few places," Jin says.

The old man is using a peephole telescope to find the underground structure, based on the data he obtained from the other day.

were more numerous than expected and were installed over a wide area.

It was assumed that they were probably distributed in such a way that they would not be affected by any civil engineering projects.

"......Oh, there is something here ......50 meters underground."

So, it is easy to find it.

"Oh, you found it already!

"Oh, there seems to be something here too. It is about 70 meters underground.

< had buried countless numbers of these of in the soil.

Approximately one per hectare.

Even if they were to be dug out, there are other <> buried around them, so they would have little effect on the soil.

Incidentally, the area affected by one <> is about 1 hectare.

( must have taken careful measures. ...... Well, I guess he didn't do it by himself.

This is Jin's impression.

The shallowest place in the nearby < was around 20 meters underground, so Jin dug a hole using and asked Reiko to retrieve it for him.

He then secretly duplicated the contents using the engineering magic <>. Later on, I will send it to Horai Island using a warp gate from , and ask the old man to analyze it.

"I see, this is inscribed with a very advanced formula.

<, there were many tiny formulas that could only be analyzed by Jin.

"According to this, it seems that ......<> is instructed to exterminate pests and diseases, distribute air, and retain moisture, etc."

"Oh, no!　Who in the world would do such a ......"

The Minister of Magic, Miko B. Safran, is amazed and astonished.

"I can only say that it is a prehistoric civilization ......."

There are still remains of what are called <> all over the world, including the old Leonard Kingdom, and those who created them are called <>.

Jin knows that they are <> from the planet Hale, but for now the planet > is a secret.

(I'd like to explain it when we can go into space. ......)

That will be a long time in the future.

Aside from that, the management of the ruins is left to each country, and they are not allowed to excavate or investigate without permission due to the unknown dangers, and are protected at least on the surface.

This is because there is a possibility that some of them may contain the products of dangerous technology, and some of them, like <>, may be living ruins.

We cannot predict what will happen if we stimulate such ruins.

(If such a > is established in , ...... then)

That is what Jin thinks.

Now, Jin has buried the < back to its original state.

"Now that all of your questions are answered, let's go back. Let's go back."

"Oh, yes."

Jin and Miko be Saffron returned to the castle of the Duke of Norway.
