There Are Small Bugs in the Water.（）
"Done." Su Bai put down the charcoal and looked at the animal skin drawing that only he could understand.
He raised his head and saw the bull-horned girl standing at the side, stretching her neck to peek at the beast skin painting. Then, their gazes met.
"Wu, I, I didn't want to peek.”Yan Hua blinked her red eyes and then reacted. She waved her hands in panic and subconsciously took a step back.
"It's okay. I'll just watch it." Su Bai's lips curled up. It was rare to see the cow-horned girl in a panic.
" Phew…" Flame Flower was relieved when she saw Su Bai was not angry. She was only curious and stole a few glances, but she was caught.
“？？？”Yu Ying stared blankly at the bull-horned girl. Didn't she say she was going to ask Wu Drinks Water? Why did he sneak a peek?
Yan Hua did not forget about her good friend. After restraining her emotions, she asked in a clear voice,"Wu, don't you like to drink cold water?”
"I like it."
Su Bai didn't think too much. He replied,"Drinking a cup of cold water on a hot day can cool you down."”
"…" Yuying pursed her lips, her mood dropping.
"I-I see."
Yan Hua's tone was a little unnatural. She stole a glance at her disappointed good friend and mustered up her courage to ask,"Shamans like to drink cold water, so why boil it?”
"Eh?" When Su Bai heard this and saw the fox-eared lady's disappointed expression, he immediately knew what was going on.
He pretended not to know and said calmly,""It's safer to boil the water.”
"Why?" Yan Hua asked subconsciously.
Yu Ying pricked up her fox ears and tried to eavesdrop on their conversation. She also wanted to know why.
"There are invisible bugs in the water. Boiling water can kill them.”Su Bai said lightly as if he was talking about a trivial matter.
"Ah?" Yan Hua was so frightened by these words that her face turned pale.
If the shaman drank the water with bugs and something happened, the Fire Dragon Tribe would be finished.
"No, it can't be." Yu Ying was so frightened that her face was extremely pale, and her pink eyes were sparkling.
"Witch, I didn't know there were bugs in the water."”
Su Bai saw that the two beast-eared girls were almost crying. He said gently: "Alright, just boil the water. It's not a big deal.”
"Xiaoyu, I don't want this pot of water." Flame Flower shouted anxiously. They had to put an end to all possibilities of harming the shaman.
"Alright." Yu Ying replied immediately.
"Stop, there's no need to pour the water."
When Su Bai saw it, he quickly stopped him: "All the water has bugs. Just boil the water.”
If he poured the water out, he would have to wait for a long time before he could drink it. Moreover, the hollow wood had not been brought to the tribe yet, so water was still very scarce.
"Wu, you mean all the water has bugs? Including the entire tribe?" Yan Hua widened her beautiful eyes in fear and asked.
"All the water, not only the water in the tribe, but also the water in the small lake.”Su Bai said with certainty.
"..." Flame Flower opened her mouth. Her throat was extremely dry, and she was so scared that she couldn't speak.
"Wu, but everyone has always been drinking this water.”Yu Ying said timidly.
"Let me ask you a few questions." Su Bai did not explain.
"Alright." The two of them nodded.
"Have you guys noticed that someone around you suddenly has diarrhea? Some people suddenly frothed at the mouth, while others suddenly fell ill.”Su Bai mentioned the characteristics of drinking unboiled water.
Of course, there were other factors that could cause it, but drinking raw water would increase the inducement by more than 50%.
The tap water that the cities on Earth drank had been treated. After the water was boiled, there was no problem at all.
However, in primitive society, raw water in the wild was not treated. It contained bacteria, eggs, and some harmful minerals. If one drank raw water for many years, diarrhea would become a common occurrence.
"..." Yan Hua's face, which had just regained its color, turned pale again. Her body trembled as if she had thought of something bad.
She gulped and said in a trembling voice,"It seems that a few people, and two others, died of illness.”
"Wu, what should we do?" Yuying's eyes were brimming with tears as she thought of someone beside her who had been hit by the shaman.
"The bugs in the water are invisible to the naked eye. You have to magnify them dozens of times to see them. They are mixed in raw water. If you drink them, they will destroy the blood and qi of the human body.”
Su Bai explained the dangers of bacteria in an easy way.
"The little bug is actually so small?" Yan Hua and Yu Ying said in astonishment.
"So the simplest way is to kill them with high temperature.”Su Bai said softly.
"I understand. In the future, water can only be drunk when it's boiled.。”Yan Hua heaved a sigh of relief. It was fine as long as there was a solution.
"It's good that you understand. I'll leave the matter of boiling water for everyone to drink to you.”Su Bai ordered.
"Alright." Flame Flower agreed without thinking.
"And this, get someone to make a few for me.”
Su Bai handed over the animal skin drawing and began to explain: "This big one is a wooden cylinder. I want this opening to be a little smaller. Use a piece of animal skin to block the bottom, and then put in charcoal and sand.”
His filter was an improved version, with three layers of charcoal and sand, so the filtered water would be much cleaner.
"Alright." Yan Hua's red eyes stared at the animal skin painting, trying hard to remember what the shaman said so that she could pass it on to the tribe's best carpenter.
"Go ahead. Give it to me tomorrow." Su Bai said softly.
"Then I'll go out first." Yan Hua took the beast skin map and hurriedly ran out of the tent. She wanted to quickly convey the shaman's request in case she forgot.
"As expected of a daughter like her father. They both have a fiery personality.”Su Bai sighed and turned to look at the fox-eared lady who was boiling water.
When he saw the jerky, he ordered,"Xiao Yu, roast some meat to eat."”
"Alright." Yu Ying replied obediently. She found a sharpened wooden stick, put on a piece of palm-sized jerky, and roasted it over the fire.
Su Bai saw what the fox-eared lady was doing and pointed out: "If you roast it with charcoal, the jerky won't be so easily blackened and will taste good.”
"Alright, alright." Yu Ying quickly removed the jerky from the flames and placed it on top of the red charcoal.
