Deus ex machina is to investigate the .

We pause at .......

"That is a bit curious," said Arnold over a cup of tea.

Arnold said as he sipped his tea.

"Somehow I have a bad feeling about it.

"Well,...... Arnold says he has a bad feeling about it, does that mean it reeks of a ?"

"Oh, Jin, you're so perceptive. Yes, that's right."

If there is a <> in such and such a place that cannot be seen from the surface of the earth, it is the previously mysterious <>......, the identity of which is unknown, but is assumed to exist somewhere, based on the large amount of missing materials. The "final weapon" is a "......", which has been a mystery until now.

"It would not be surprising that such an underground facility would have some means of not accepting contamination, or that they could have brought soil from another location when they buried it," he said.

Arnold, who had built an underground base before, was the only one to speculate on this.

* * * *

Well, I would like to discuss the some more, but break time is over.

"We will resume then. <

The facilitator, Marcel, the king's brother, announced.

"We are going to discuss the future of ......, that is, the . < or the ."

"In our prior discussions, you said that you would choose from ."

"Yes. Where should we choose?

"It would be better to have a town or village nearby. I think it would be better to choose a place north of the town of .

The town of Bororon is where the <> got its name.

It is also a key point on the road connecting the Kingdom of Cerroa and the Shoro Empire.

"I see no particular reason to object."

I have no objection.

No objections.

It was unanimously agreed to designate an area about 10 kilometers north of the town of Bororon, one kilometer square, as the , and to mark the area with red stakes at the four corners.

The site was located on the southern outskirts of the , which would become the in about two kilometers.

< is such that no protection is needed, so it is easy to come and go.

However, even in <> there are no health problems as long as people do not eat without washing their hands after playing with the soil.

"Then, between the town of Bororon and the <>, let's sow seeds of and ."

"I see, the way you have suggested seems to be very efficient.

Again, no one raised any objections, and the decision was made without a hitch.

The decision was made without any objections from anyone.

"Now, as the last item on the agenda, we would like to decide how we will carry out decontamination at the experimental site. Do you have any suggestions, Mr. Lorona?"

Marcel, the king's brother, addressed Lorona by name.

"The basic idea is to dig up the contaminated soil, decontaminate it, and restore it to its original state.

"I'm sure you're right."

Agriculture and Forestry Minister Bowanni said there was no other way.

"Well, if ...... is the case, there is no problem with using magic tools to pinpoint and remove the contaminants."

The contaminants are <>.

If you are Jin, it is possible to make a tool to remove () them.

"Yes, it is. It is ......, but, Jin-san, the scale is ......."

Yes, in this case, depth is more important than area.

However, if the crops are decontaminated to a depth of about 2 meters, there should be virtually no problem, but Jin did not think so.

"But it would be better to decontaminate the area properly for later use, wouldn't it?

"That's right, but it's a lot of work ......."

Even Lorona looks reluctant.

He knows how difficult it is to decontaminate at a depth of 20 or 30 meters.

"We'll figure it out."

However, Jin had not come up with anything yet.

If this were Horai Island, there are many ways to do it, such as using the <> to roll up the soil within the physical boundary, decontaminate it, and return it to its original state, or using the <> and other space ships to dig up the soil for decontamination, or creating tens of thousands of special worm-shaped magical machines (Magi Machines) to do the work, etc. There are many ways to do this, ...... thinks.

But Jin is a little worried about the best way to do this in other countries.

"I think it would be better to dig a hole or a moat to the required depth, say 20 or 30 meters, first, and then proceed.

This is Arnold's advice.

Dig up the soil, decontaminate it, backfill it, dig up right next to it again, decontaminate it, backfill it .......

This approach is very inefficient, he says.

In other words, we should decontaminate the soil we dig while digging <>.

The idea is the same as the one Jin had planned to do with the .

"I see, we can attach a to those shovels and shovels."

"What?"

"What?"

Everyone could not believe their ears when they heard Jin's words, which sounded almost like he was talking to himself. The only one who did not doubt was Makina.

"Shall we make the handles of shovels and shovels hollow so that the extracted contaminants can be stored in them?

In Jin's mind, <> is a shovel that can be handled with one hand, and <> is a large shovel.

This is the eastern terminology, while in western Japan it seems to be the other way around. ......An aside.

"But still, 30 meters is too big to do it all at once. ......"

At this point Jin begins to consider the possibility of <>.

"...... anyone familiar with <>?"

"Oh, I can help you with that.

To Jin's murmur, Delphina answered "Oh, I'll take care of that.

"Well then, can you help me a little after this?

"Yes, if it's something I can do.

Thus began the discussion on the unusual combination. .......
