I was a village chief in a primitive society

Chapter 28: There are small bugs in the water. (please collect)

"Done."Su Bai put down the charcoal and looked at the animal skin picture that only he could understand.

He looked up and saw the horned lady standing next to her, stretching her neck to peek at the animal skin picture. Then their eyes met.

"Wu, I, I don't mean to peek."Yanhua blinked her red eyes, then realized what she was doing. She waved her hands in a panic and took a step back subconsciously.

"It's okay, just watch it."The corners of Su Bai's mouth raised slightly. It was rare to see Niujiao Niang panicking.

"call……"When Yan Hua saw Su Bai's lifeless look, her heart immediately relaxed. She just took a few peeks out of curiosity and was caught revealing herself.

"？？？"Yuying stared blankly at Niujiao Niang. Didn't she ask the witch about drinking water? Why did you just take a peek?

Yanhua did not forget about her good friend. After calming down her emotions, she asked in a clear voice:"Wu, don't you like drinking cold water?"

"Like it.

Su Bai didn't think too much and replied:"Drinking a glass of cold water can cool down on a hot day.""

"……"Yuying pursed her lips and became depressed.

"This, this is it. Yanhua

's tone was a little unnatural. She glanced secretly at her lost friend and asked bravely:"Witches like to drink cold water, why do they need to boil the water?""

"Huh?"When Su Bai heard this and saw Fox-Eared Girl's disappointed expression, he immediately knew what was going on. He pretended not to know and said calmly:"It is safer to boil the water."

"Why? Yanhua asked subconsciously.

Yuying pricked up her fox ears and tried her best to listen to the conversation between the two, and also wanted to know why.

"There are small invisible bugs in the water, which can be killed by boiling the water."Su Bai said lightly, as if he was talking about a very small thing.

"ah?"Yanhua was so frightened by these words that her face turned pale.

If Wu drank the water with bugs and something happened, the Yanlong tribe would be doomed.

"No, it won't."Yu Ying was so frightened that her face turned extremely pale, and her pink eyes were gleaming.

She said in panic:"Witch, I didn't know there were insects in the water."

Su Bai was so frightened that he almost cried when he saw the two beast-eared girls. He said gently:"Okay, just boil the water. It's nothing serious."

"Xiaoyu, I don’t want this pot of water anymore."Yanhua shouted urgently, now we must eliminate all possibilities that may harm Wu

"good."Yuying immediately responded

"Stop, don't pour the water. When Su Bai saw it, he quickly stopped him and said,"There are small bugs in all the water. Just boil the water.""

If the water is poured out, he will have to wait for a long time to drink the water. Moreover, the hollow wood has not yet been received by the tribe, and the water is still in short supply.

"Wu, are you saying that all water has bugs? Does all include the entire tribe? Yanhua asked with her beautiful eyes widened in fear.

"All water, not only the water in the tribe, but also the water in the small lake."Su Bai said with certainty.

"……"Yanhua opened her mouth, her throat was very dry now, and she was so frightened that she could not speak.

"Wu, but everyone drinks this water all the time. Yuying said timidly

"Let me ask you a few questions."Su Bai didn't explain.

"good."The two of them nodded in unison.

"Have you ever noticed that someone around you suddenly has diarrhea? Some people suddenly foam at the mouth; some people suddenly fall ill."Su Bai said several characteristics of drinking raw water frequently.

Of course, there are other factors, but the inducement after drinking raw water will increase to more than 50%.

The tap water consumed in cities on the earth has been treated. , and then boiling the water again will be no problem.

But in primitive societies, raw water in the wild has not been treated. It contains bacteria, insect eggs, and some harmful minerals. If you drink raw water for many years, Diarrhea will become a common occurrence

"……"Yanhua's face, which had just regained color, turned pale with fright again, and she shivered all over, as if she was thinking of something bad.

She swallowed her saliva and said with a trembling voice:"It seems that there are several people, and two people are sick and died.""

"Wu, what should I do?"Yu Ying burst into tears, thinking that someone around her had been tricked by the witchcraft.

"The small bugs in the water are invisible to the naked eye. You have to magnify them dozens or hundreds of times to see them. If they are mixed in the raw water, if you drink them in the stomach, they will destroy the body's qi and blood. Over time, you will get sick and have diarrhea."

Su Bai explained the dangers of bacteria in an easy-to-understand manner.

"The bug is actually so small?"Yanhua and Yuying said in shock.

"So the easiest way is to kill them with high temperature."Su Bai said softly

"I understand. From now on, the water must be boiled before you can drink it."Yanhua breathed a sigh of relief, as long as there is still a solution

"As long as you understand, I will leave it to you to ask everyone to boil water before drinking it."Su Bai ordered smoothly.

"OK"Yanhua agreed without thinking.

"And this, please ask someone to make a few for me."

Su Bai handed over the animal skin picture, and then explained:"This big one is a wooden tube. I want the opening to be smaller. Use a piece of animal skin to block the bottom, and then fill it with charcoal and sand. Divide it into three parts. Layer to install."

His filter is an improved version. It has three layers of charcoal and three layers of sand. The filtered water will be much cleaner."

"OK"Yanhua's red eyes were fixed on the animal skin picture, trying to remember what the witch said so that he could tell it to the most powerful carpenter in the tribe.

"Go ahead and prepare it for me tomorrow."Su Bai said softly

"Then I'll go out first."Yanhua took the animal skin picture and trotted out of the tent quickly, rushing to convey the witch's request, lest she forget it later.

"As expected, like father, like daughter, both have fiery personalities."Su Bai sighed and turned to look at the fox-eared lady who was boiling water.

He saw that the meat was dry and ordered:"Xiaoyu, roast some meat and eat it."

"OK"Yu Ying responded obediently, found a whittled stick, put on a piece of palm-sized dried meat, and grilled it on the fire.

Su Bai saw the movements of the fox-eared lady and gave instructions:"Bake it with charcoal. Dried meat will not be blackened so easily and will taste delicious"

"Okay, okay."Yuying quickly removed the dried meat from the flame and placed it on top of the red charcoal.
