< Turles officially joined the , the island of Penglai was crowded with people.

Dinner naturally turned into a banquet.

However, it was not a boisterous party, but rather a more lively dinner than usual.

"Mr. Turles, I'm so happy to see you.

"Thank you, Marikka."

"<>, I look forward to working with you.

"It is my pleasure, Mr. Jin."

Rouge and Neige are also happy to see Turles.

"Father, you look so happy."

"Yes. I've never seen my father's face like that.

"We're happy too."

"That's true."

The members of the Jin family greet Turles in turn.

"Elder, please continue to teach me everything you know."

"Mr. Turles, thank you very much for your guidance.

"It's really encouraging to have you officially join us, Mr. Turles.

"As an elder, I would be happy to have your guidance.

And so on.

After these exchanges, the topic of conversation naturally turned to the Somark Ruins.

"Were there any germs or toxic gases in that underground?"

Milowina asked anxiously.

After all, she is a descendant of people who migrated to the Moon to avoid the plague. No wonder she was concerned.

"Yes. According to the analysis of < who accompanied me, there has been a major disinfection once or twice in the past."

That's what caused the smell of phenol, Guth replied.

"If the originals didn't do it, then a follower race, a follower golem, or a follower automata must have done it.

So you're saying there was a situation that needed to be disinfected?

That's what I'm saying.

"I mean, did something go wrong, like a plague or something rotten? ......"

There was no record of it?

No.

"Then what does ...... mean?"

Here is the old man's opinion.

<>

"That's true."

> had ceased to function.

The reason was that the presence of the smell of coal acid (phenol) must have been relatively recent.

"Yeah, that's for sure."

When coal acid (phenol) is used for disinfection, it should be diluted, not undiluted.

For disinfection of the human body, use a concentration of 1 to 2 percent, and for disinfection of other ...... medical tools and articles, use a concentration of 2 to 5 percent.

The fact that it is so diluted and the smell is still there means that it must not be more than a few thousand years old.

"Well, your guess is as good as mine.

Turles agreed with his guess.

"That would mean that someone came here after the Somark Ruins became uninhabited.

Reinhard said. Lewis added.

"That would be right. I would add that it must be the <> or one of its followers living in another <>."

"In other words, when you scavenged the Somark ruins, you disinfected them just in case?"

"That's what I think."

This theory of Reinhardt and Lewis was accepted by the other members.

For the moment, there is no way to verify it.

"Then the next question is, what about ?"

Goose says.

"If you go there, you can find all sorts of stuff that was taken away ......, maybe recycled."

If they are reused, they are probably used as they are or slightly modified and maintained, but if they are recycled, they are probably not kept in their original form since they are reused after being returned to their original materials.

But even leaving that aside, it is very significant to find <>.

The technological superiority of the is still undeniable, and if they make one mistake, they could become the enemy of the current human race of Ars.

< and on . .......

"So you didn't find any clues about other ?"

Zion asked.

"Not enough to call them clues, but I can guess that there is one relatively close by."

Goose answered.

The rationale, he said, is that it would take less effort and energy to come to a to recycle than to use the resources that are underground.

In other words, it would be so close that it would be very easy to collect.

"Well, that opinion is half right and half wrong," Turles said.

Turles said.

"Because the act of recycling itself seems to have become a part of our lives. Also, to make things from underground resources, we need to consider the < at that time. ......

The concentration of free ether at that time was low in the southern hemisphere, so these underground cities were built and the concentration of free ether was raised only in their interiors to make them living spaces.

Therefore, it was Turles' opinion that the production from materials that would consume more free magical element (ether) was probably avoided as much as possible.

"What do you think, Jin-dono?

When it comes to manufacturing, it is Jin.

He asked Jin to judge which of them consumed more free magical element (ether).

The point is to compare <> with .

"Well, if we assume that <> is used to move ......, I guess recycling is the way to go."

The transfer magic circle takes a long time to activate, but it is perfect for such a case, since it can transfer with a small amount of magic power consumption.

"I see, if Jin says so, it must be so. In other words, it is not always nearby.

Guth's shoulders drooped a little, but the old man denied it.

"Oh!

We did it!

So where is it?

<

The old man projected a map of the northeastern part of the Rasheer continent on the large magic screen and marked it for Jin and the others to see.
