I'm bad and I'm hitting a wall, primitive life requires hard work

Nishi Ichiki finally understood why this disease was called 'rainy season disease'.

The people of the Yanluo tribe all drink stream water directly. Fortunately, the stream water outside the tribe flows down from a mountain with a very high altitude, so it is relatively clean.

Although there are some bacteria in the stream water, the people of the primitive tribe have become accustomed to such an environment and have iron stomachs.

However, rainwater contains not only sulfur dioxide and nitrogen dioxide, but also some pollutants and dust in the air during its fall. It contains a lot of bacteria, which can irritate the gastric mucosa, cause gastrointestinal discomfort, abdominal pain, diarrhea and other adverse reactions, thus causing damage to our health.

Moreover, even filtering cannot completely remove these harmful substances.

Not to mention that in this strange world, no one knows whether there are other unknown substances hidden in the rainwater, and there is no way to detect them.

When the rainy season comes, once the tribe’s stored water is used up and there is not enough food, the tribesmen will drink some rain water to fill their stomachs.

At this time, people with weaker constitutions will experience stomach pain a few days after the rainy season after drinking rain water.

"Don't drink rain water anymore, Ste." Xi Yiqi gently stroked Ste's little head and took the stone bowl handed to him by Wu Yu, which contained freshly mashed medicine juice.

She picked up the bowl carefully and fed it to Ste in small sips.

"Why is this?" Siduo asked curiously.

"Rainy season disease is not a disease that you will get when the rainy season comes. It is diarrhea caused by drinking rain water, that is, stomach pain and diarrhea."

Nishi Ichisu then briefly explained to everyone that rainwater actually contains a lot of dirt and is very unclean. Drinking it directly may cause harm to the body.

All the tribesmen widened their eyes and stared at Nishi Ichiki in disbelief.

Who would have thought that the "rainy season disease" that has been plaguing them was actually caused by drinking rain water.

"So what should we do now?" A series of anxious questions rang out from the crowd.

Although the witch doctors in the tribe can treat this "rainy season disease", the stomach pain is really uncomfortable!

"The best way is to stop drinking rainwater directly, including the stream water we usually drink. It needs to be boiled before drinking." Xi Yiqi said seriously.

"So that's what happened. But now we don't even have water..." Nimei's voice was filled with worry.

I was so busy explaining that I forgot about this.

The sudden heavy rain caught the tribe off guard, so the stored stream water was soon depleted.

For human beings, water is the source of life.

They can survive three weeks without food, but most people cannot survive more than three days without water.

In the past, the tribesmen would definitely not care too much about what Nimei said. After all, they always felt that rain water was as clean as stream water, so there was nothing wrong with drinking some.

But after hearing what Nishi Ichiki said, everyone knew that drinking rain water would cause "rainy season disease", and they all looked anxious.

"What should we do now?" Siduo asked worriedly, frowning.

This sudden and long-lasting rainstorm has put everyone in one predicament after another.

"There's no water. Let's just go to the stream and fetch some more water." Young Yan Ya tilted his head, listened carefully to the adults' discussion, and put forward his own ideas.

Nishi Ichisu looked down at Yanya's clear, bright eyes and said gently, "Yanya's idea is good, but the stream water is very dirty during the rainy season. You can't drink it directly from now on."

Yes, during the rainy season, the stream water will become turbid.

In the past, the people of the Yanyuan tribe didn’t care about the color of the stream water. They would just drink it directly after scooping out the large debris in it.

They also did not associate the "monsoon disease" with this incident at all.

Now after listening to Wu Xiqi's words, everyone felt a little hesitant. Even clear stream water needs to be boiled before drinking, so turbid stream water must be even more so.

"Wu Xiqi, if we can't even drink stream water directly, then where should we find drinkable water?" The patriarch, who had been standing by and watching the development of the situation, raised the most critical question.

Nishi Ichisu remembered some survival techniques he had read before, put down the stone bowl in his hand, stood up and said to the tribe leader: "We can still get water from the stream."

Chen Qi frowned after hearing this: "But didn't you just say that stream water can't be drunk directly? Do you mean to bring the turbid stream water back and boil it?"

Nishi Ichiki just nodded and then shook his head.

Everyone was even more puzzled.

"We do need to bring the turbid stream water back and boil it, but before that, we need to filter it so that it becomes drinkable water directly," explained Nishi Ichisu.

"What is filtering?" Wu Yu looked at the successor in front of him with confusion.

Wu Xiqi's performance exceeded his expectations.

Mother Nature taught him how to cure the "rainy season disease", but he didn't know why his people were infected with this disease.

The girl in front of him had obviously inherited something unusual, and she always had something strange and new to say.

"Filtration is a way to make water clean. I can't explain it in detail, but you will understand it in a while." Nishi Yiqi thought about it and realized that she really couldn't explain the meaning of some modern terms to primitive people.

Although her golden finger is an automatic translation, who knows what it sounds like to their ears.

"Okay, can I leave this matter to you?" Chen Qi had full trust in Xi Yiqi. Yesterday's ditch incident had already proved her ability.

Although she was only fourteen years old, the wisdom she displayed was impressive, and she had gradually acquired the calm demeanor of a great witch. The chief looked at her with satisfaction, his eyes full of admiration.

"I believe that with her and Wu Yu's help, the Yanyuan tribe will get better and better." Chen Qi thought to himself.

"Okay, Chief. But I may need some help." Nishi Ichiki nodded and put forward his request without any hesitation.

"What do you need?" asked the patriarch.

"I need two strong warriors to help me carry a jar of stream water back, and I also need some people to help find some things. These things are easy to find and not heavy. Women and children can do it."

Nishi Ichisu clearly stated his needs.

The patriarch responded: "Okay."

He glanced at the crowd, and before he could open his mouth to choose people, a bunch of tribesmen couldn't wait to express their willingness to help.

They all very much hope to do something for the tribe to overcome its current difficulties.

Yan Luo and a man named Arthur were named by the patriarch to stay.

These two men are tall and strong with well-defined muscles.

If they encounter danger, their strong bodies are enough to protect Nishi Ichiki.

After all, as the rain gradually subsides, not only humans will go out to look for food, but hungry wild beasts may also break into the tribe's territory.

In addition to these two strong men, Nishi Ichiki only selected two people of similar age to help him find supplies.

There are not many available people in the tribe.

The hunting team had to go out to look for prey, and the women had to hurry out to find food when the rain stopped.

It is best for injured people, pregnant women, the elderly and young children to stay away from the rain because they have weaker resistance and are more likely to get sick.
