If the foundation is good, it will be time to build a house.

In fact, Xu Yin really wants to build a kiln to burn bricks, but she doesn't know enough about the world, and if it is illegal to build a private kiln, it will outweigh the losses.

In the afternoon, mixing yellow mud with clay to paste the wall, Xu Yin saw Chen Mancang a few, and went to the small river half a mile away to carry water, and he was tired when he looked at it.

But there is no water source near this wasteland, and the mountain is just an ordinary firewood mountain, and there is a stream and it is very small.

Building a house and clearing the land requires a lot of water.

After thinking about it, Xu Yin decided to build a waterwheel.

However, it was not the solar waterwheel that was boldly tinkered with the back of the palace during the Yan Dynasty, but the water turning and overturning with the help of hydraulic power.

If the water is gentle, you need rickshaw water to drive the waterwheel. Therefore, when using water, people need to be watching from the sidelines at all times.

Chen Mancang and the others had never heard of the water turning overturned, so Xu Yin took a branch and drew it on the gravel ground to show them:

"Build it in the upper reaches of the river, and from here here we dig a ditch. When the ditch is fully filled with water, everyone can try to grow rice even if they want to, and dig a hole in the ditch to release water into the fields. As long as the river is not dry, we have a steady stream of water to use, and we don't need to run to the river to pick it up. ”

After everyone understood, they cheered, and when they calmed down, they couldn't help but worry: "Brother hero, can this water turn and overturn car really be built?" ”

"Yes!" Xu Yin gave them a reassurance, "I am responsible for building the waterwheel, and you divide the labor to cut down trees and dig ditches." ”

"That's fine!"

"That's it! What is this work? ”

Xu Yin said with a smile: "Even if the waterwheel is built, someone must be there to guard it when it is urgent to use water." When the water flow is slow, the running speed of the water wheel will not be too fast, and people need to drive it from time to time. When the time comes, let's make a plan, and each family will come in turn! ”

"As long as there is water, I can let my boy stay by the waterwheel every day."

"Yes, the leather monkeys are idle, send them some work!"

Xu Yin saw that they could all understand, so she didn't say more.

Just when Xu Yin was tinkering with the drawings and overturning, a group of people ran over and knelt down for her.

Xu Yin: "......"

The other party slapped himself while crying: "It's a small one who has eyes and doesn't know Taishan, and he offended the hero!" Small wrong! Please also have a large number of heroes, spare a small one! The little one is willing to follow the hero in this life, and only asks the hero to save the life of the little one! ”

Xu Yin recognized it when he shouted heroically: Isn't this the man with broken eyebrows who was thrown after the robbery on Chai Mountain?

Which one is this singing?

Chen Mancang knew him and explained a few words: "His father and mother are dying, they were already so weak that they couldn't speak because of the lack of food and water before, and they were even more sick after being drenched in the rain a few days ago." In fact, I persuaded him to come to you for soup that day, but I don't know what he thought, and he refused to come. ”

Xu Yin guessed that the reason why he refused to come was because he was worried that he would recognize him and refuse to give him the medicine.

Seeing that Xu Yin didn't speak, the man with broken eyebrows continued to kowtow and beg: "My father and mother are dying...... Ask the hero to save my father's life! As long as I can save my father and mother, I will be a cow and a horse for the rest of my life......"

Xu Yin hurriedly asked him to get up: "It's okay to go and see your father, but I have a word first, I'm not a doctor, I just have medicine for wind and cold, if they don't get wind cold, then I ...... too."

"If even the hero's medicine can't cure them, it can only be said that all this is fate!" The man with broken eyebrows said with red eyes.

Xu Yin sighed silently, turned out his dowry baggage, and said that he would go to see his father and mother.

Erlang was not at ease and insisted on following.

Xu Yin shook her head: "You stay here to take care of the third sister." Wind and cold are easily contagious, and I am cautious along the way, for fear that you two will get sick. What did I tell you before? Try not to go to crowded places. You're not listening to me? ”

Erlang had to take the third sister to stay and watch the house.

There's no shadow of home...... The two children continued to mix mud and paste the stone walls.

At this time, Xu Yin followed Shi Feng to the place where he placed his father.

The two elderly people have been groggy since the rain, and they have been rushing for days to cause a high fever that did not go away last night.

Xu Yin took out a bottle of spirits from her baggage and asked Shi Feng to wipe his father and mother to cool down.

Then while Shi Feng was busy, he stuffed a fever-reducing medicine into the mouth of the unconscious old man and fed a few mouthfuls of spiritual spring water.

"Hero, you want to boil medicine, right? I've made a fire! Shi Fengnian, who had robbed Xu Yin with Shi Feng before and was kicked by her, came over cautiously with Xiaoxiao.

Xu Yin looked at him trembling and said with a smile: "Don't do that kind of unreasonable thing, I won't do anything to you." ”

"No more! No more! Definitely not again! We were ...... Hi! The family is waiting to eat and drink, if it weren't for the desperation, they wouldn't have such evil thoughts, but after being taught by the hero, they accepted that heart, and they really didn't do it! ”

"So you've done a lot before?" Xu Yin glanced at him with a smile.

"Huh? No, no, no, no! That day was our first time, and I finally had the courage to stop you, and I was ...... It's true! I could swear to God! ”

"That's it! Let's make a fire! ”

"Hey!"

With both antipyretics and physical cooling, Shi Feng's parents quickly lost their fever.

Xu Yin instructed them to drink more water, to boil the warm water, not to drink raw water.

By the way, it has also spread the importance of raw water to the body.

Many people don't think so, thinking that it is good to have water to drink, and the stream in the mountains is not dirty, so it doesn't cost firewood to boil and drink.

But people like Shi Feng, Chen Mancang and others took Xu Yin's advice to heart.

I'd rather spend a little effort and effort to make a few more trips to Chai Mountain and pick up more firewood to come back.

The firewood in Xu Yin's house has not been cut off since that day.

Chen Mancang and Shi Feng took turns to send her firewood, and seeing that she was scraping the bark for the wood of the waterwheel, she took the initiative to grab it and dry it, and a lot of the waste wood cut down was quite strong, so she surrounded Xu Yin with a fence as a courtyard wall.

Xu Yin didn't let them help in vain, and boiled some medicinal porridge for them to drink from time to time.

The crowd gathered firewood and the flame was high. Soon, the water turned and the car was built.

However, because there are no professional woodworking tools, the construction is relatively rough, but it does not affect the use.

The ditch has also been dug from the river to the end of the barren field. When passing through the walking section, Xu Yin chiseled a stone slab out and laid it on top so that the children would not fall into it.

Everything was ready, and she commanded the crowd to assemble the waterwheel.

Then show them how to show it.

As she moved the water, the waterwheel slowly turned.

"Pop ......"

"Bang ......"

The small drawers on the waterwheel, one by one, sank into the river and exposed the surface of the river.

The bucket filled with water rises to a certain height, and when it passes through the mouth of the ditch, it "booms", the bucket turns over and the water is poured into the ditch.

It's amazing!
