Doctor’s Rebirth - Chapter 271

Episode 271:

At the market, I bought ceramics resembling long bamboo tubes and designed and made various things.

“What are you doing?”

Wangya must have been curious as he was doing something while holding on to such a long piece of pottery.

What Jin Cheon-hee was doing was simple.

Put some cotton inside. Plant-based fabrics commonly used in this region are added in layers.

Then, make charcoal from the coconut shell and burn it.

Grind it and make it into fine powder several times.

Let it dry naturally again in a sunny place.

Find a fruit similar to a lemon in this area and mix it with its juice.

It was aged again and then heated again…

It was something that would have seemed crazy.

“We make activated carbon.”

“Activated carbon?”

“Um… some kind of filtration water filter… or rather, a strainer.”

“It’s a filtration purification strainer… If you just listen to the word, it seems like a tool that makes water clean… Is that right?”

“You are as smart as expected. “You guessed it right.”

Put activated carbon in a long pottery, cover it with fiber and cotton, add activated carbon again, and then add elvan stone.

In such a long container, something was being stacked layer by layer, like strata.

“But does making it that way make it pure water?”

Would you understand if I told you that I was making ‘Life Straw’?

What Jin Cheon-hee is doing is appropriate technology.

So, it is an inexpensive but necessary technology that can be used even in developing countries.

We wanted to create products made with appropriate technology in this central area.

Life Straw.

When you have to drink contaminated water in Africa, you can naturally filter out parasites and bacteria by putting your mouth to this straw and drinking.

The filters inside act as a shield.

When it first came out, it wasn’t that difficult to make, the price was very cheap by the standards of developed countries, and it was very easy to use.

Received the best treatment with appropriate technology.

‘The problem was that the price was cheap by developed country standards.’

By African standards, it was a murder price.

As a result, it could be said to have failed as an appropriate technology.

It was judged that there were sufficient conditions for use here, so production began immediately.

However, we cannot know the golden ratio between the thickness of the cotton and the amount of activated carbon that forms the layer, so we are making several samples and testing them.

‘Once this is completed, the messengers will be much more comfortable.’

Water is scarce in the desert.

Since there is no firewood to start a fire, camels have to carry it from the beginning.

However, things in the desert do not go as desired.

The weather may be nice today, but tomorrow you may get lost in the sandstorm.

If a swarm of magic bandits appears, you must risk your life and burden whether you win or lose.

The only water source at that time was an oasis.

Water contaminated with bacteria and parasites.

Of course, Wanong’s well is also polluted, but since it is a water source, it is strictly managed by the government, so it is nothing compared to an oasis.

The difficulty of finding firewood to boil water is incomparable.

Considering the income of the traders, there was enough room to purchase this life straw, and it was not difficult to obtain the materials from the central region.

‘A sip of water can save your life, so why not make it?’

Jin Cheon-hee explained to Eunwang-ya so that she could understand as much as possible.

Eunwangya was lost in thought while rubbing his chin and said this.

“If it is possible as you say, it will be helpful not only to the soldiers crossing the desert but also to the countless soldiers crossing rough terrain.”

“yes. First of all, we can prepare for local endemic diseases caused by contaminated water. “Of course, it’s not all-powerful.”

“I think that alone would be amazing… but the question is whether it can be made as easily as it sounds.”

It’s not like you need a lot of fieldwork skills.

Activated carbon is difficult enough for charcoal lovers to make.

‘If we succeed, many lives can be saved.’

It is impossible to eradicate all parasites anyway.

Even if we purify as much as possible in an era where there are no water or sewage pipes, there are limits.

However, many situations like the Three Princes caused by local parasites can be prevented.

‘I wish we would be careful about animal feces.’

Since it is a zoonotic parasite, you should also be careful with horse feces.

‘It would be good if we go in with the soap supply.’

First of all, testing the life straw comes first.

Eunwangya said.

“good night. Then I will give you five days. “If you succeed within five days, I will give you a reward.”

Oh, is it good?

* * *

So the various samples were completed and the moment of experimentation arrived.

The experimental method was simple. Just suck it.

It is Hwang-gu who will evaluate success.

Jin Cheon-hee dipped the life straw in muddy water and lightly sucked the water with a suction cup instead of sucking it with her mouth.

Wow!

When seen with the naked eye, it looked like clear water, but Hwanggu had other thoughts.

“Um… okay. Then I’ll take it out twice.”

Try again.

Cry!

“Better than before? “Is the ratio of activated carbon the problem?”

I keep repeating that.

“I need to apply a layer of glaze on the inside of the pottery… this…”

I tried combining the special glaze on the pottery a few more times and firing it. Later, Eunwangya personally recruited his father-in-law to help Jin Cheonhee.

Just before the final exam.

Eunwangya said he would send a human to conduct the experiment himself.

‘Can I just use my suction?’

Well… I guess that could be the case since I’m assuming it was used the way it was originally used.

And then one human arrived.

“Ah… Hello. Inspector.”

A familiar face was politely approaching Jin Cheon-hee.

“Ship… white captain?”

Looking at his clothes, he seemed to have been stripped of his qualifications as a white commander. He was wearing the armor of an ordinary soldier, his flashy sword gone, and he came with only a spear for distribution.

“You’re a hundred people. Is this even relevant to my topic? “I have now come to a place where I fit in.”

It’s fast… Is it possible for things to be done this quickly?

“No… uh… you’re not going into exile?”

I decided to just ask straight up what happened.

“He said it was a waste to pay taxes to send him into exile… so His Majesty confiscated my assets and gave me a chance to atone for my sins.”

‘Well, in a remote area like this, serving as a white-armed army means that you will just suck up labor until you die.’

Eunwangya and Geumwangya, who works with him, don’t like money being drained from the treasury like this.

If this guy were to become a big official, he would be punished by extermination or execution.

It would be a waste to send a minnow like this on a forced package tour called exile.

Even though I was thinking about killing myself, it was a waste of money I lost.

‘I think it would be better to cut my head.’

Since he said he would give us a chance to wash away our sins, I wonder if God would just torture us in moderation and then send us off to die at the right time…

Eunwangya is not very merciful to sinners.

He will thoroughly use them as outcasts, but when the time comes, he will turn them into immortals in an appropriate place.

And that first mission.

“Can I put this ceramic bowl in the mud and suck the hole on the other side with my mouth?”

If the experiment failed, I would have an upset stomach tomorrow, and the parasites would slowly establish a kingdom inside my body over the next year.

“That…”

In a world without human rights, evildoers have no more human rights.

Jin Cheon-hee scratched her cheek and said.

“We’ve already done several experiments using suction, so it’s probably safe.”

“Yes, yes. That’s right. I know.”

Only then does the head of the squadron look relieved.

‘It looks like Wangya is already doing a great job.’

Even though I feel as sad as an ant’s claw, I don’t feel that way when I look at Hwanggu’s face.

‘okay. ‘You have to spit out as much as you eat.’

Jin Cheon-hee decided to put an iron plate on her face.

Then a voice rang out.

“Are we already doing a practical experiment?”

Eunwangya and the three princes wearing masks were leisurely walking together.

Luxurious clothes and strange elegance. Even though his face was covered with a mask, he exuded a sense of intimidation.

When Baek In-jang was about to bow down, Eunwangya said.

“Oh, I am an ordinary merchant. Don’t worry about it, just do what you’re doing. “This is just my friend.”

Baek In-jang said, sighing at the mention of a merchant.

“Oh, thank goodness. “As a soldier in charge of His Majesty’s duties, I cannot bow my head to just anyone.”

‘Oh look at you strutting around.’

This guy was golden from the start.

Even during this time, he is trying to gain a share by becoming close to the owner of the merchant.

When I saw that, all the sympathy I had secretly felt disappeared.

“Hehe, you are a person who is doing the country’s work.”

As expected, Eunwangya’s lips gently twitched beneath the mask.

Anyone else would see it as a friendly smile, but in Jin Cheon-hee’s eyes, it was the opposite.

It feels like a lion watching a sheep and measuring its kill angle, and it makes my stomach tingle.

The head of the squadron swept his beard as if he had no idea.

“Kuhm. “It’s not a very great position.”

‘I don’t know anymore. Just wash it quickly and go home quickly.’

There’s nothing a good adult can do other than pray for this bastard’s rest in peace.

Let me wash it quickly and get it checked quickly. Send it home quickly.

All I can do is light some incense for this guy in a week or so.

“Let’s do it quickly.”

“Geuhum inspector, you don’t have to be in such a hurry…”

Did you smell the money in the silk that Eunwangya was wearing? Why is your tongue so long?

“Just go ahead and do it.”

Under Jin Cheon-hee’s silent pressure, the squadron leader reluctantly squats down in front of the muddy water.

Then, he slowly dipped the tube into the water and sucked it.

His expression is dark, as if he is anticipating a future in which he will have to drink muddy water. But that too only for a moment.

“oh?”

“are you okay?”

At that time, Hwanggu barked lowly.

Wow!

Even the wagging of the tail was a clear sign of ‘passing’.

The head of the squadron said.

“It’s a little uncomfortable to suck, but the muddy water tastes like well water.”

“Get your pulse right away.”

Jin Cheon-hee put his hand on the neck of the former Baek In-jang and tried to force a deep breath.

‘It sure looks like there’s no problem?’

However, it is too early to completely let down our guard.

“Could you come back in a day?”

“I will do whatever the inspector says. Hehehe.”

Rub both hands together vigorously.

“Well… I just said I worked hard before…”

This is my true intention, after all. He’s definitely not a smart guy compared to his greed.

“All right. please! “I’ll tell you.”

Jin Cheon-hee glanced at Eunwang-ya and immediately continued speaking.

Eunwangya laughed as if Jin Cheonhee was having fun.
