Zhou Ziyi sounded the principle of the suggested filter that he had seen in modern times.

Bamboo charcoal, coarse sand and fine sand, and finally a cotton cloth filter, she thought she could try it.

So at the end of the day, she asked Chai Yang to go to the kiln to burn a huge filter, and she gave her a drawing.

ァ新ヤ~(8)~1~Chinese 網ωωω.χ~8.~1zщ.còм

Chai Yang has become a little strange since he came back from the woods, and he doesn't refute Zhou Ziyi, he can do whatever he wants, Zhou Ziyi thinks it's pretty good.

I don't know what method he used, but on the third morning, he came back with a super large filter.

According to Zhou Ziyi's idea, they want to set up this thing in the place where everyone in the village goes to collect water every day, so that the stream water can enter the tank by itself from the pipe on the side of this filter. Then, they were next to it, and the bottom layer was cotton cloth, then fine sand, then cotton cloth, coarse sand, and finally bamboo charcoal that everyone in the village had made themselves.

At the bottom of the filter, there is a hole that can be stuffed up on weekdays and then open when needed.

This filter is large, and the water flow is not small.

After this was done, everyone brought in the water source. Hundreds of pairs of eyes in the whole village stared at this strange behemoth, not knowing what kind of changes it could bring.

One drop, two drops, three drops from the beginning.

Slowly, the flow of water begins to gradually continue, and finally, the flow of water becomes larger and larger. In a few minutes, a bucket of water was released.

The water that came out was no longer the yellowed water it used to be, and its color became very clear.

The big guys all looked at the thing excitedly, "That's amazing, girl, that's how you thought of it?" ”

Zhou Ziyi was stunned, right, how did she come up with it?

Everyone looked at her expectantly, and she had no choice but to put the blame on Gu Chengyu again. "Yes...... It was Mr. Gu who told me! ”

The big guy excitedly went to Gu Chengyu again to thank him.

Zhou Ziyi breathed a sigh of relief, and then thought about it, something was wrong, Gu Chengyu asked her what to do?

……

Although the water was in a hurry, Zhou Ziyi still told them that the water must be cooked before drinking. Not only that, but she also asked Chai Yang to show up and tell everyone about the disgusting situation on the mountain.

The big guys all looked disgusted, and they all said that they would never drink raw water again in the future.

When everyone dispersed, Gu Chengyu beckoned and called Zhou Ziyi, "Come here." ”

Zhou Ziyi actually wanted to run, but when she wanted to run as a monk, she couldn't run to the temple. Gu Chengyu would always remember this matter in his heart, so he simply walked over.

Taking a deep breath, Zhou Ziyi said, "The matter of that filter body is actually ......"

Before the words fell, Gu Chengyu had already directly grabbed her hand, "Are you okay?" Listen to Gu An, did you meet a wolf today? ”

Zhou Ziyi was stunned, "You ......"

"Hurt?" Gu Chengyu's face changed slightly, "Where?" Why don't you call a doctor? Doctor!!! ”

"It's not!" Zhou Ziyi looked at his nervous expression, and her heart warmed slightly.

"I'm not hurt."

"Really not hurt?" Gu Chengyu relieved his mind at this time, "Next time this kind of thing, don't go, a girl's house, it's too dangerous." ”

Zhou Ziyi sighed, and then said, "Why don't you ask me about the filter?" ”

Gu Chengyu looked at her, "Why do you ask?" If you want to say it, you will naturally say it. ”

"Don't you think I'm weird, then? Don't you wonder if I'm going to be some kind of demon or something? ”

Gu Chengyu was stunned for a long time before shaking his head, "If you are a demon, then I am a little ghost, a natural pair." ”

Zhou Ziyi, "......" Mom, this product is fine?
