Yang Cheng wanted to throw a healing spell to Xia.
But Xia was not injured.
Throwing the healing spell to her had no effect other than keeping her body warm.
Yang Cheng thought about it and gave up.
He had no choice but to touch Xia's two antlers distressedly and carefully wipe the sweat from her face.
At this moment.
Everyone in the Qingque tribe is already wondering and discussing:
"Will you get sick if you drink raw water?"
"Is there such a thing?"
"This is what the witch said, so of course it's true!"
"What will happen next? Are we not going to drink water?"
…
Yang Cheng stood up, waved his hands, and said, "Everyone, listen to me."
Everyone suddenly became quiet.
Yang Cheng repeated what he had just said to Yan Lin and others.
When everyone heard that there were small insects in the water, everyone changed their colors.
Hearing that Yang Cheng almost drank the bug's water, he was panicked and a little lucky at the same time.
Fortunately, the witch knew there were bugs in the water and didn't drink it.
There is no problem if people like them get sick, but if the witches get sick, the tribe will be doomed.
As for why Wu knew there were bugs in the water?
You don’t need to think about this problem to understand it.
When a witch accepted the inheritance, he must have learned it from the knowledge in the inheritance.
"Witch, if there are bugs in the water, what should we do if we drink the water?"
At this time, Yan Hu suddenly asked.
His words reminded everyone, and everyone was nervous and looked at Yang Cheng.
Water is the cradle of life.
If you don't drink water, you will die of thirst.
Yang Cheng smiled and said, "It's okay. As long as everyone filters the water first and then drinks the boiled water to kill the little bugs in it, there will be no problem."
"filter?"
"boil?"
Everyone in the Qingque tribe was puzzled when they heard these two words.
Yang Cheng did not explain, but said directly: "Yanhu, go and chop a piece of bamboo, it needs to be this big."
Yang Cheng pointed to a tree stump on the ground, which was about two meters in diameter.
Yesterday, Yang Cheng walked around the tribe and found a bamboo forest growing to the west of the tribe.
The bamboos in the bamboo forest are not as big as on the earth. Each bamboo is at least 1.5 meters in diameter, and some large bamboos are 3 meters in diameter.
"Yes, Wu."
Except for matters involving danger to Yang Cheng's life, Yan Hu obeyed Yang Chengdu in other matters.
After listening to Yang Cheng's request, Yan Hu nodded, took a stone ax and went out.
"Yan Lin, take some people to pick up some charcoal that we didn't finish burning yesterday's barbecue."
Charcoal is the most important ingredient in making a water purifier, as it can absorb most of the fine particles and toxins in the water.
"oh."
Yan Lin responded and ordered a few people to leave the cave.
Seeing Yan Lin being assigned a task, Xing couldn't wait to step forward and shook Yang Cheng's arm: "Wu, what about me? Xing also has to work!"
"You have a job to do!"
Yang Cheng touched her head and said, "Take some people with you to collect sand and small stones. Remember to make sure there are no dirty things on them."
Xing nodded ignorantly, nodded to a few people, and ran away in a hurry. She didn't want to fall behind Yan Lin.
"Okay, you all go to work. Remember, don't drink raw water anymore. If you are thirsty, just endure it. If not, just eat the fruit."
Yang Cheng said to the remaining tribesmen, "You will definitely be able to drink water later!"
Although the people in the tribe didn't understand what Yang Cheng was going to do, they were full of confidence in Yang Cheng, so they all agreed and went to work immediately.
Yang Cheng made people optimistic about Xia again.
Then walked out of the cave.
When they got outside, Yan Hu carried a bamboo tree with a diameter of two meters and a length of seven or eight meters. He walked easily and came over effortlessly.
He walked up to Yang Cheng and said, "Witch, I got the bamboo."
"Well, let's put it down first."
"good."
Yanhu put the bamboo on the ground.
"Bang!"
The bamboo collided with the ground, making a loud impact.
It can be seen that the ground has sunk a few centimeters.
Seeing this scene, Yang Cheng's eyelids jumped.
The idea of the power of the totem warrior goes one step further.
Yang Cheng originally thought that bamboo was relatively light, but judging from the few centimeters pressed down from the ground, bamboo in primitive society was similar to pine on the earth.
At this time.
Yan Lin and Xing also ran over with their people.
The two of them collected enough charcoal, sand, and small stones.
After the order was executed, Yan Hu and others turned their attention to Yang Cheng, looking at him eagerly, waiting for the next move.
Yang Cheng thought for a while and said, "Yan Hu, cut off these three pieces."
As he spoke, Yang Cheng pointed to the upper end, the middle end, and the lower end of the bamboo.
The diameters of these three sections of bamboo are from small to large.
Yanhu nodded, took a bone knife and sharpened it on the stone, and then started cutting quickly on the bamboo.
The bone knife was naturally not as sharp as an iron tool, but it was cut quickly and tirelessly by Yan Hu.
The three bamboo sections are easily cut.
Yang Cheng then asked Yanhu to carve some small holes for water leakage at the bottom of the three bamboo joints.
Then she asked Yan Lin to put the charcoal inside the bamboo joints and spread it, and asked Xing to spread sand and small stones on top of the charcoal.
Then put the three bamboo sections together vertically.
Due to the different caliber sizes, the three bamboo sections are just stuck and connected to each other.
In this way, the simplest water purifier is ready.
The top layer of pebbles can compact the sand and charcoal below, while filtering out larger particles in the water.
The middle layer of fine sand is used to filter smaller particles from the water.
The bottom layer of charcoal is used to absorb colored and odorous substances in the water, as well as a large number of toxins.
Plus three bamboo sections, three layers of filtration.
More than 90% of the impurities and toxins in raw water can definitely be filtered out.
"Okay, bring the bamboo bucket." Yang Cheng said.
Immediately, some tribesmen brought some bamboo buckets over.
Yang Cheng asked Yanhu to filter the filter with a wooden cane tied in mid-air. He also placed a diabolo bucket below, and then took a bamboo bucket filled with water and poured water into the top layer.
And during this period.
Yanlin and Xing were like curious babies, squatting next to the water purification device, touching left and right.
The tiger ears are shaking and the succubus tail is raised, looking very cute.
Waiting for the somewhat turbid water with impurities to pass through three layers of filtration, it flows into the bamboo bucket through several small holes at the bottom of the water purification device, turning into clear and clean water.
Yanlin's tiger ears stopped twitching, and Xing's tail also stopped wagging.
The two beast-eared girls opened their eyes wide in surprise!
Not only them, but the people in the Qingque tribe who were watching were also in disbelief!
