At dinner the day after the method of making the reet stone was found, Sigel decided to listen to what he was concerned about.

"I was looking at Takel's diary and I thought, is the relic of the time really only enough for the Great Spirit to manage it?

"Yeah? What do you mean?

To Siegel's doubts, Philomena asked, tilting her neck.

Already in Philomena, he thought Sigel was right, so he didn't know what he wanted to say.

To Philomena's inquiry, Sigel nodded only once before continuing.

"Yeah. I know the technology of prehistoric civilization hasn't passed on at all right now, but I was wondering if that's really all."

"... what do you mean?

Michaela reacted to Sigel's words this time.

However, it was Michaela who raised her voice, but the others have a similar face.

Looking around at those faces, Sigel spoke slowly as she sorted out her thoughts.

"As far as Takel's diary goes, the ruins up there were functioning properly as a town at the time."

"Oh, that's right"

"So, prehistoric civilization used the ruins to further their own use," he said.

I don't know if I continued to use what I originally used, or if I maintained an abandoned town so that it could be used again.

But what we know from the materials that remain is that the prehistoric civilizations used it as a proper town.

Watching everyone snort, Sigel made room for just a little while before continuing further.

"- Then can't you assume that the other ruins were in the same condition?

"Same condition......"

It was Filomena, who repeated Sigel's words, but quickly gave her a hazy look as she noticed something.

"... Sigel wants to say that the ruins that remain now are not prehistoric civilizations either but remnants of the civilization that preceded them?

Philomena, who understood Sigel's thoughts, asked him so to confirm.

Sigel nodded at it,

"Of course, though I wouldn't say it's all like that. Besides, there's still evidence that maybe?

"Evidence? Could that have happened?

"Reed Stone Method"

Sigel nodded again and said so briefly to Marina, who had come to hear that as she leaned her neck.

It was Filomena, who had been doing the trick of thinking for a little while to Sigel's answer, but eventually became the kind of face he understood.

"Right. You know what?"

Philomena, who found that her own whining had concentrated the gaze of the others, continued her words as they were.

"Reed stones are considered commonly used as building materials even in prehistoric civilizations. However, the method has not been found so far. It was simply thought that those dossiers had not been found, but Sigel is actually trying to say otherwise, isn't it?

That's what I'm talking about.

Sigel nodded as she answered, understanding that what she wanted to say was being properly passed on to Philomena.

If, indeed, the prehistoric civilization had made a reetstone with its own technical skills, it should be possible for the method to remain as a dossier as well.

It can be deduced that the fact that it has not been found at all is that the prehistoric civilization did not actually know how to make the reetstone either.

Besides, I've heard from Nola that Philomena affirms that we can make it whether we have manpower problems or current technology.

I can only assume that there is some reason why a civilization that is said to have developed numerous methods of making magic props did not leave behind such an easy way of making reetstones.

If that's just because you didn't know how to make it and you were just reusing the remnants of the ruins of the civilization that preceded it, that could happen.

It shouldn't be just a way of thinking that doesn't leave the realm of speculation, but it can never be.

However, Sigel and Philomena also knew exactly that it was still just an imagination.

"Well, if they say it's a little too forceful, that's it."

Filomena shook her neck left and right as Sigel clasped her shoulders with a slightly loose face.

"No, that's not what you made fun of, is it? Somehow, there must have been some scholars who actually made those claims."

"Huh!?

Sigel looked at Filomena with a few eyes open.

The marina continued to snort as she took over that Philomena word.

"Could it have been an assertion that prehistoric civilization was a civilization made up of borrowed knowledge? Although, of course, they're kicking ass that that can't be happening. No, there he is, isn't there?

"Sure, some institutions said that"

Laura, who had heard Marina's words and looked as if she remembered something, nodded as she said so.

"But surely those who were not supposed to claim that they were the survivors of the clan that produced those knowledge?

When Laura went on to ask him that, Filomena turned sinister.

"Because I'm saying it, I wasn't looking forward to the original claim either."

"Uh, does that mean that the current story could seem like the kind of paranoia we've been putting out"

When Sigel said so with a sigh, the others turned sinister.

Sigel, who once looked around at those faces, went on to say even more.

"Well, there's no evidence or anything at all. It's just a reasoning, so I guess I don't have to do much ahead of me?

I nodded in unison to Sigel, who argued that it would be better to gather properly evidence-like evidence and then rethink it, as we all agreed, as it was not out of the realm of reasoning now.

Two years ago (?) Even the claim that civilization existed is still doubtful.

On top of that, it cannot be admitted where just inferences based on it were made, and on the contrary, the claim that two previous civilizations could even be treated in colour.

It was everyone's unanimous view that it was better to avoid that.

Anyway, Siegel's claim was to be put on hold because of the challenges ahead.

If we can find evidence to support that claim, we'll talk about it together.

More than that, we must first prove exactly that there were two previous civilizations.

In order to do so, we should first properly proceed with the investigation of the site, which brings together the story of this occasion.

Maintenance of the Amateras was three days, and Sigels' stay was only scheduled for the meantime.

And on the last third day, Aerial came all the way to Siegel's place to report completion of maintenance.

Besides, just after finishing dinner, Sigel was laughing at the appearance that only seemed to be the timing he was after.

"Uh, thanks for taking the time. Mainte, are you done?

"Yeah, it's over. You didn't have any major problems."

"Yes. That's good"

Siegel sighed in relief at Aerial's report.

He thinks it's hard to treat Sigel badly and cause him great damage just because he still has the awareness that he's just keeping it.

For this reason, he thought that if problems were found in the first long term maintenance, that would be the problem.

Towards Sigel like that, Aerial laughed and showed it to me.

"You don't have to be so cautious, if you don't treat me like that, you'll be fine because there's nothing you can do to ruin it."

"Really? I hope so."

"Yes, yes. Oh, I'll tell you at last, but if you engage with a dragon, you don't get your hands on it badly, because I try to avoid it from the other side. Exactly, because in self-defense, they can attack."

Sigel nodded in a serious way to important information from Aerial.

There were demons flying in the sky, naturally, in this world, and they used to talk about what to do.

I looked at Sigel, who said thank you for telling me and lowered his head, and Aerial, who nodded small, told me to add at the end.

"It's time for Merriage, why don't we head to the next place? I got a corner ship. My advice is Mount Porpot. More than that, we can look for ourselves."

That's all I said, Aerial disappeared from the spot as he waved.

And Sigel, who was left behind, saw the Philomenas for a little while.

"Uh, that's the word, isn't it?

I nodded to Sigel, who didn't dare to be specific, as Philomena looked the same.

"Well, I guess so. Thanks to the Great Spirit of the Wind, did you find your next destination? … there is a slight problem."

When Philomena said so, the other three, with the exception of Sigel, were nodding with a straight face.

It wasn't until a little later that Siegel knew what it meant.
