Early the next morning, everyone was busy. The little daughters-in-law and the girls were busy making shoes for the big guys in the tents, and the half-grown lads were driven by the adults to mow the grass around the camp, leaving some young men in the camp to help the hammers and make iron, while the old ladies were busy with the big guys' lunches in front of the stove.

Mu Chenghu stood in front of the tent and watched this scene, and couldn't help but wonder in his heart that without this disaster, everyone would still be living a life of sunrise and sunset in Mujia Village. Now that I think about it, the life I was tired of is so unattainable, I would rather be a peaceful dog than a troubled person.

"Chenghu, a few more children started to have diarrhea today. What can I do about this? Mu Qingliu's words interrupted Mu Chenghu's thoughts.

"Uncle San, how much medicine do we have now?" Mu Chenghu asked.

"It's enough for just these children, but I'm afraid that there will be people with diarrhea in the back." Mu Qingliu said worriedly.

"Speaking of which, it's still the problem of water, mainly because these children start to drink water indiscriminately as soon as their parents are not careful." Mu Chenghu's words hit the nail on the head.

"Dad, why don't we let the children take care of themselves." Mu Yao, who was driven out by her second aunt to make shoes, heard the words of the two and said.

"Oh, how to manage it, you tell your father." Mu Chenghu asked curiously.

Mu Qingliu looked at Mu Chenghu a little speechlessly, thinking that you really take your children's words seriously, how can these children manage themselves well.

"Dad, don't you still have some red dates in the second uncle! All we had to do was tell the children that if they didn't drink the water from the river, they would give each person a date, and then let them supervise each other, and if anyone drank the water from the river, they would be rewarded with a date. Originally, I thought that Mu Yao was talking about Mu Qingliu, but when I heard Mu Yao say this, I immediately felt that it was feasible.

"My daughter is really powerful, just do as you say!" Mu Chenghu praised without hesitation.

Mu Yao thought to himself that his father was in a hurry, otherwise he couldn't have thought of this idea?

After Mu Chenghu took Mu Yao to Han and asked for a lot of red dates, he asked Mu Yao to call all the children for a meeting.

After lunch, Mu Chenghu took a few villagers to start changing the stove, but fortunately, there were catkins on the side to secretly guide him, and the stove was changed well.

Everyone was happy to see the dead grass burning in the stove.

"This grass is not resistant to burning, how can you cook!" At a time when everyone was happy, someone asked questions.

This question can ask Mu Chenghu, and when Mu Chenghu was thinking about how to answer, Liu Wu stood up.

Everyone saw catkins pick up a handful of grass from the ground and pull it into a ball.

"Let's burn it again." The catkins handed the grass to the fire-burner.

Everyone looked at the grass in the stove with a curious expression, only Mu Chenghu looked at the catkins with some concern, but the catkins gave him a reassuring look.

The grass in the stove burned for a long time before it was finished, and everyone was curious when they saw this.

"Third brother and sister, what's going on?" Mu Chenghu's second sister-in-law who asked.

"Actually, I don't know what's going on, it's what I'm doing in my hometown, I just know what to do, and I don't know why."

Liu Wu said half-truthfully. Because catkins are just a person of unknown origin here, there is no way to verify it.

After listening to Liu Wu's words, no one asked anymore.

After the stove was changed, everyone hurriedly began to pack up their things before it was dark, and set off early the next morning.

Suddenly, Mu Yao, who was packing up in front of the tent, pointed to a pile of carbon and said to Mu Chenghu, "Dad, isn't that the bamboo charcoal we burned when we were in that bamboo forest before?" ”

Mu Chenghu looked at Mu Yao's fingers and found that it was really bamboo charcoal, Mu Chenghu said happily, "Fortunately, I haven't had time to burn it yet." ”

Mu Chenghu asked people to put these bamboo charcoal in addition.

After Mu Chenghu arranged for people to load bamboo charcoal, he took a few young men to dig a big pit not far from the river, and after digging the pit, Mu Chenghu asked people to lay a layer of bamboo charcoal at the bottom of the pit, and after laying the charcoal, Mu Chenghu asked people to lay a layer of pebbles on the charcoal, and finally Mu Chenghu asked people to introduce the yellow river water into the pit.

The few young men who had done all this looked at Mu Chenghu with some puzzlement.

"Wait and see!" Mu Chenghu looked at the expressions of several people and said secretly.

Several people were reluctant to say when they saw Mu Chenghu, although they were very curious, no one asked again.

A few people stood quietly beside the pit and looked at the water in the pit, and after a while, they found that the water began to slowly become clear, and the water was completely clear after three quarters of an hour.

For a while, several young people looked at Mu Chenghu with admiration.

Seeing everyone looking at him, Mu Chenghu said, "What are you still doing here, why don't you hurry back and find a guy to fetch water." ”

"Third uncle, don't be in a hurry to fetch water for a while, or you can tell us what is going on first." Qiu Cheng asked boldly.

"I told you to read more on weekdays, but you didn't believe it, but now it's okay. In fact, this bamboo charcoal has the effect of adsorbing impurities and harmful components in the water. This is what I read from your great-grandfather's travelogue. Mu Chenghu said with a smile.

"Third uncle, is that travelogue still there? If you have a chance in the future, can you lend me a look? Qiu Cheng asked.

"I wanted to lend it to you, but the problem is that the book was lost a few years ago." Mu Chenghu said with a regretful face.

Qiu Cheng also said with a regretful face: "It's a pity." ”

"Let's go, go back and let everyone come and fetch water." Mu Chenghu looked at the sky and urged a few people to hurry back.

On the way back, Mu Chenghu looked at Qiu Cheng, who had a regretful face, and thought, where can I find that book for you, it seems that I will try to be as reliable as possible in the future.

When the group returned to the camp and told everyone that there was clear water to drink, the whole camp cheered. However, Mu Chenghu still told everyone to boil the water before drinking.

Mu Qingliu knew that it was Mu Chenghu who found a way to purify the water, so he said to Mu Chenghu, "Chenghu, the people of our village will be handed over to you, you will definitely be able to take us all out." ”

Mu Chenghu listened to Mu Qingliu's words, and had mixed feelings for a while.
