On October 18, the members of the Jin Family and the set out to survey the in a hurricane.

The first step of the survey was to observe from the sky.

In other words, it was the first stage of their survey.

The pilot is Hope.

The plane took us from Horai Island to Onogoro Island by .

There is a half-day time difference. We left Horai Island at 6:00 p.m. on the 18th.

Onogoro Island was at 6:00 a.m. on the 18th.

It's morning.

"It's morning."

With the morning sun in the background, the hurricane is flying towards the western continent.

The weather is suitably clear, and we can look down from high above.

"Kuhu, it's been a while since I've been here, but it's still amazing.

Saki laughed.

Looking down on the eastern part of the Rasil Continent from an altitude of 5,000 meters.

There are two major rivers flowing there. <

Jin asks who named them, and is told that it was Goose.

He says that they are the names of the rivers in the journal written by <>.

(It must be a mistake in writing the Tigris and Euphrates rivers. ......)

...... and Jin thought only in his mind.

The high mountain in the west is Mount Harvest. To the east of it rises the gently sloping Mount Canlin.

<

The two great rivers unite in the upper reaches, and their source is Lake Veliyas at the northern foot of Mount Kanlin.

To the north of Lake Belyas, there is a smaller lake called <> and a larger lake called <>.

Only the bare minimum of place names are given.

And .......

"Jungle. ......"

"Jungle, huh?"

There was a jungle in the interior.

"It's been a while since I've seen it, but I can't tell the topography from this. ......

Goose says.

"I'm thinking it might be near water."

This is Vivian.

The history of the earth is that civilizations have developed near rivers since ancient times.

The four great civilizations of the world are the Egyptian, Mesopotamian, Indus, and Yellow River civilizations.

Each of these civilizations developed in the basin of a major river: the Nile, the Tigris-Euphrates, the Indus, and the Yellow River.

Knowing this, Vivian thought that the site must be near water.

"Hmmm, but in an underground city, there could be groundwater.

Maybe we don't have to go that far," Goose said.

< is flying west, just before the splits into the and the .

On the right side, there is a gentle low mountain called .

The Dyson River turns to the north and ends up at Lake Beryas.

The <> turned clockwise around the <> and headed east.

"Well, this one is not so much a jungle as a ...... but a forest."

Jin was disappointed that his observations from the sky were not as effective as he had expected.

"But it's nice that we can all take a leisurely flight together like this."

Milowina said with a smiling face.

Everyone's faces lit up in sympathy with this mood.

"Okay, let's have tea then.

It was just before noon local time, but it was already 11:00 p.m. in Horai Island time, and if they were still awake, they would want to eat something for the night.

So, I prepared something easy to digest and low in calories, which was .

Though <> doesn't gain weight, but that's just my mood.

Tokoroten. Also written as "shindai" (heart).

It is made from agar made from the seaweed, tengusa, and pressed into a thin noodle shape using a device called a "tensuki".

It is eaten with nihaizu (vinegar) or sanhaizu (vinegar), or with molasses or soybean flour.

Tokoroten is usually made from chilled boiled and squeezed juice of tengusa seaweed, and has an aroma of the sea, but the one served here is made from agar-agar tokoroten, so it is non-harmful and can be eaten in many different ways.

For example, Jin had sanbaizu (vinegar), Elsa and Licia had molasses and soybean flour.

Hannah, Martha, and Meine use two cups of vinegar.

Reinhard served it with very sweet red wine.

Saki had black sesame and soybean flour, Bina, Luis, and Vivienne had honey.

The other members also had their own favorite, some of them like anmitsu, some of them like fruit punch, and some of them like .......

They ate it according to their own tastes.

And tea is served.

This time it is stem tea.

It is made by mixing the young branches of tea trees, the stems of tea leaves, and the stems of tea shoots.

It is characterized by its fresh aroma and refreshing taste.

It is a little lower in caffeine than other green teas, so it is used as a nighttime snack. Not really related to <, but it's also my mood.

"Oh, that was delicious."

"It's different when you eat it in the sky."

"It really is."

Jin thinks about the old days when he went hiking in the nearby mountains and even a simple cup of ramen tasted good.

* * * * * *

"Well, we've been touring the northeastern part of the Rasheer continent.

After finishing his tea, Jin tells everyone again.

"It turns out that it's not quite what we expected."

"Kuhu, right. ......

"Well, it is what it is."

"If it weren't for the jungle, I might know a little more."

Everyone is a little disappointed.

"But I'm still going to go with the river. Or near those lakes, <>, <>, <>..."

"Well, I see what you're saying Goose, but I'd guess where the Dyson River splits in two."

"Yes, Vivienne has a good point. Yes, Vivienne makes a good point. It certainly looks like it could be somewhere around there.

We decided to leave it as a candidate site to be investigated.

I'll just have to wait and see what happens.

"Also, I'd like to use <> ......"

"I wonder..."

Reinhardt responded to Jin's mutter.

"I don't know," Reinhardt responded. "If we carelessly use such search magic, it may not be perceived as a hostile act by the management magic brains.

"That's what I mean."

"Well, since they've gone to such great lengths to hide and live here, such a reaction is quite possible."

"Of course."

So, it is unlikely that we will be able to investigate the underground resources of the four duchies as we did in the past.

Speaking of which, ......

"Brother Jin, what's wrong?"

Coming to the Rasheer continent reminded Jin of something.

"Well, I found Reiko on the western edge of this continent..."

"Wasn't it, father?"

"Yes, I remember."

Theon nodded a little nostalgically.

It was the time when Jin had wandered into this time period from 400 years ago.

< had sought out the dormant Reiko and tried to destroy her.

Theon suggested this to me, and I found Reiko and reactivated her safely.

At that time, Reiko cleaned up the enemy golems in the vicinity, but it is not surprising that there are still some of them left.

"......Should we search for them and clean them up?"

"I agree!　Let's return to the atom any golem that tries to destroy Reiko-sama!

Hanako, that's a bit extreme, isn't it?

The radical line was Hanako's.

Hanako, the automata that Marikka created for Reiko, respects and admires Reiko.

Therefore, the very existence of a golem whose purpose is to destroy Reiko is unforgivable.

"Well, I understand your feelings, and it is not good to have such a golem remaining on this continent, so let's take this opportunity to clean it up.

That was the decision.
