Once transferred, Sage, I was reincarnated and became the son of the Demon King. ~ Eh ⁉ The sixteenth place in throne inheritance would be too low ~

That night we arrived at 'Kaonji', arguably a mountain city. We were invited to a welcome feast, where we fell asleep, savoring the local cuisine of the territory.

The next day.

Wake up. I'm ready to go. [M]

"Okay, like this"

Confirm that you are not uncomfortable with the outfit you are wearing.

"We have something for Master Lewie's back length, are you okay?

I'm wearing clothes made of fabric made in the territory here.

It stands out in the clothes I wore until I came to this territory on the boulder, so I decided to wear the clothes made in this territory.

This outfit won't make you think I'm the Prince of the Devil's Kingdom in case the soldiers of the Twelve Clans find me.

"No problem. Sophie, I'll take care of the rest."

"Yes, by the time you get home, we'll be looking into the proceeds, specialties, soil, etc for this territory"

"Please."

Revenue, of course, is important because with specialties we can use it to commerce, and if we look at the soil in this territory, we know what crops we can grow.

Let Sophie take care of the neighborhood, and we'll head to the 'Qinghai'.

I leave my room and head to the garden.

There are people waiting with me on their way to the 'Qinghai'.

When I headed to the garden, I was waiting for my mother, twenty people who I believe belong to Sister Fell and Sister Fell, Tina, Arian, local residents who would follow me as directions, and finally Dr. Melvina for some reason.

This member is going to Kiyokai.

You came to see me off, and Mr. Raymond was there.

Please return safely.

"Of course. I'm going to come back as soon as I can."

"Ha, I look forward to your return"

Mr. Raymond bowed his head.

I nodded and Tina came over with the horse's warcraft compass.

Crossing the horse's warcraft, I looked around.

"Now we're going to the 'Qinghai'. Don't fail to inspect your equipment."

When I proclaimed that, they all rode horse warcraft.

Arian also saw riding the horse's warcraft and wondered if it would be good.

Now he looks human, but Arian is a warcraft. Then I guess I'm on the Warcraft because I don't think I can go back to where I was, but I'm not going to go back in person.

So make it whatever you want.

General, I rode, so I led Sister Fell and ten of her men and residents, and then proceeded in the order of Arian, Tina, Dr. Melvina, me, and the tail of the remaining Sister Fell's men and mothers.

After leaving Kaonji, we rushed north for about half a day and arrived at the desired "Qinghai".

Looking at the lake, it's a really beautiful lake.

It was a truly clear blue lake, even if I stopped by nearby to see it.

Close to the land was visible to the bottom of the water.

That's all the transparent shame, or I can see that not a single fish is swimming.

"That's pretty big, this lake. I wonder how wide it is."

"Neither do I. If it's a map of the north, you might find out more, but honestly, you have no idea how big this lake is."

"Is it the same depth?

When I asked, the residents of the guide nodded.

Hmm. Sometimes this lake is said to be a cursed lake without a single fish.

"So, are you sure whoever drank the water from this lake is dead?

"Yes, he died after suffering for a few days"

"When he died, what was his condition?"

"Yes, I complained of physical discomfort, further chills, nausea, unusual high fever, diarrhea, etc. At the end of the day, he looked like a mummy, like he was losing moisture in his body."

Hmm. You look like cholera.

I wonder if we should consider that this lake has cholera bacteria.

Well, then, there's something to deal with.

"Sister Fell. Do you have anything you asked for?

"Yeah, I brought it."

Sister Fell signaled by hand.

Then the men came to me with cloth, charcoal and a large funnel.

Good thing there was charcoal. Later.

"After that, bring sand and stone, because it's small, it's good"

"Sand and stone? So what do you do?

"I'll show you when I collect it."

When I said that, Sister Fell gave instructions to her men.

Eventually, the men brought large quantities of pebbles and sand.

"Uh-huh. I brought it."

"Thank you, then, for staying in the funnel I brought, in the order of pebbles, sand, charcoal and cloth."

"? Okay."

Sister Fell lays things down in the funnel like she was told, with a face that doesn't know what she's going to do.

"Then it puts the water in the lake there. Oh, put a bottle under the cylinder."

"Foolish. You were listening, the water in this lake."

"It's okay, this way it wasn't a water microbe. Because bad ingredients can be filtered."

"Filtration? What, is that?

"Simply put, this is how you can drink the water from the lake."

"... is that true?

"Yeah. I read it in a book, so I'm fine"

It's a book I called in my previous life, but it'll be fine.

"Hmm. Well, even if I'm wrong, I can handle it"

Mother, the way you say it, it sounds like I'm lying, so stop it.

"All right, Fell. Do it that way."

"Huh. Okay."

Sister Fell had her men draw the water from the lake.

The inhabitants who guided me through the situation look frightened.

You believe this lake is cursed because there are dead people out there.

And the water that my men had drawn was flushed into the funnel.

First the water creeps into the cloth, then goes through the charcoal, and the sand absorbs the water and finally proceeds into the pebble and flows into the bottle under the cylinder.

"Finally, put this filtered water inside the cauldron and bring it to a boil and it's over"

"Why are you bringing it to a boil?

"It's a task to completely eliminate unfiltered bad ingredients."

"Right."

"Huh. Well, somebody, put this water in the kettle and bring it to a boil."

"Ha."

When Sister Fell instructs, her men put filtered water into the cauldron and set it on fire and boil.

As I thought it would take me a while to boil down, I noticed that Arian was watching "Shinkai" jizzily.

"Arian. Anything wrong?

When I called out concerned, Arian looked at me.

"Master, no, I was exploring because there was a sign of acquaintance"

"Do you know him?"

This is the lake, right? If so, I guess the warcraft that lives in this lake.

"What kind of people do you know?

"In a nutshell, he's the one with a warm personality that doesn't look great on giants. It's the warmest thing I know."

"Heh, by the way, that."

"Uh-huh."

When I tried to ask Arian what she knew, Sister Fell called me out loud.

What is it? If it boils and cools, you can drink it normally.

I'm going under Sister Fell.

"What's wrong?

"Look at this."

Sister Fell pointed to the cauldron.

I wondered if there was anything there, and I peered into the cauldron.

A white crystal was formed in boiling water.

"If I had boiled the water, I could have done it at some point, but you know what this is?

"... anyone, don't you have balls? If you can, the guy with the hole."

"Uh-huh. There are no holes in the boulder, but there are balls."

Sister Fell had her men bring her balls.

When I received the balls, I swallowed each of the white crystalline waters.

I threw the water away and left only the white crystals in my balls.

"This could be..."

I licked the white crystal.

As soon as the white crystals entered the mouth, the soothing taste spread into the mouth.

"This is salt."

"Salt? But you have to go to the sea or the mountains to get salt. How can you, if you boil the water in the lake, do salt?

"Sure, if you boil the water in the ocean, it becomes salt, and if you go to the mountains, there's rock salt, but there's also a saltwater lake called Salt Lake."

"Salt Lake. Then this lake will boil the water of"

It'll be salt.

When I heard that, they all made a scene.

I never thought this lake was salt lake.

Don't make this a specialty.
