I farmed and raised cubs in ancient times

Chapter 76
The overturning is that people use their feet to pedal, and then the rollers roll, and the water is sent from the low-lying fields to the high-lying fields like a conveyor belt.

This waterwheel already represents the highest level of technology in ancient times.Jiang Zhi didn't feel disgusted in her heart, but was full of awe.Regardless of the era they were born in, people are trying to survive.

The old man saw that Jiang Zhi really cared about the waterwheel, and he was not a person with impure thoughts, so he explained a lot.

Jiang Zhi bid farewell to the old man after observing, and led Ye Heng back the same way.Along the way, she was teaching Ye Heng to recognize some vegetation, and at the same time checking the water flow of the Xiaoye River.To build a waterwheel by the river, one must first understand the actual situation, adapt measures to local conditions, and then consider whether it is possible to build one.

The Xiaoye River flows through the edge of Yejia Village, and Xuejiazhuang is on the other side of the river. Compared with Qikuada Village, Yejia Village is downstream, so the water volume is larger than Qikuada Village.

There are farmlands on both sides of the river bank. At this moment, all rice is in the flowering stage and even earing.

At this time, there is a lack of water, and the harvest will be directly halved.

In the past few days, Jiang Zhi saw villagers carrying river water to the fields to maintain the growth of rice in the rice fields.

But the waterwheel could not be built within ten days by Erlang's carpenter's apprenticeship alone.Jiang Zhi thought, maybe she could think of another way.

Back home, it was almost dark, the two older children made a simple dinner, Jiang Zhi had no appetite and only ate half a bowl.

"Is sister-in-law worrying about the lack of water in the fields?" Ye Erlang asked.

Ye Xiaomei said: "If it doesn't rain again today, we will really have no harvest this year."

"Sister-in-law and younger sister, don't worry. Starting tomorrow, I will carry water from the river to the field after school, and the rice will not dry out." Ye Erlang clenched his fists to show his strength.

Jiang Zhi smiled lightly and said, "Is Erlang's picture for the embankment today?"

Ye Erlang nodded in agreement.

"Why build a dam?" Jiang Zhi asked.

"It's for flood protection."

"So it's blocked."

Ye Erlang thought for a while and said, "That's what it means."

"There is a shortage of water in the fields now, but there are a few more fields between our field and the Xiaoye River, and the terrain is so high that the water below cannot come up..." Before Jiang Zhi finished speaking, Ye Erlang snatched it away.

"Today, Mr. Xiu told us the story of grinding an iron pestle into a needle. I don't believe that if I carry buckets one by one, the field will not be full." Ye Erlang's tone seemed to be a little emotional, he thought Sister-in-law is denying his ability.

Jiang Zhidao: "Erlang, listen to me."

"Yes." Ye Erlang lowered his head halfway.

Jiang Zhi asked Ye Erlang: "How many liters is a bucket of water?"

"This... about twenty liters." He didn't know the exact amount.

"Then let me ask you again, how many liters of water can this acre of land hold?"

"Ah, sister-in-law, you are embarrassing me! How would I know?" Ye Erlang was stunned. He just said that he went out to fetch water to irrigate the rice fields. Why did he just mention how much water a field can hold?
"Second brother still doesn't understand, sister-in-law is a joke. You only know how to use brute force to do things, but you make mistakes. Our family has two acres of land. If you only rely on you to carry water, when will we go?" Ye Xiaomei turned her head and covered her mouth and smiled. .

"I really haven't thought about it." Ye Erlang said with a red face.

"So just now I asked you what the dam was for. You said it was for flood control, so what method did Dayu use to control the water?"

"I know!" Xiaowa Ye Heng raised her hand and said, "It's 'the principle on the left, the rule on the right, at four o'clock, to open Kyushu, pass through nine roads, improve Jiuze, and pass through Jiushan.'" Ye Heng said every word After reciting it decently, he smiled and waited for Jiang Zhi's compliment.

"As expected of mother's sweetheart, she's smart."

Ye Heng was praised and smiled even brighter.

"So the method Dayu used to control the water is sparse." Jiang Zhi stroked Ye Heng's soft hair.This fine fur, like a kitten, feels very cool to the touch.

Ye Erlang was confused again: "But what does this have to do with the lack of water in our fields? Our field is high, and the river's water can't be retained no matter what."

"We'll go over if the mountain doesn't come over. I made such a big detour with you. I just want to draw out my thoughts. Erlang don't want to take it to heart." Jiang Zhi smiled kindly.

"How could it be? Sister-in-law has her own reasons." After studying in school for nearly three months, Ye Erlang naturally knows what enlightenment is.My sister-in-law is guiding him, telling him not to dig into the horns when encountering difficulties.

"Today I went to Qikuaitian Village and saw their waterwheels and overturned vehicles. The reason why they can use waterwheels is because their rice fields are at the same level as the river bank, or even lower than the river bank, so the waterwheels can transport water to Tanaka, but the actual situation here is not the case, we can use overturned cars, but the land by the river belongs to Wang Fugui's family, I will definitely not take advantage of them."

Jiang Zhi is very stingy in life, so don't expect her to repay you with kindness.

"Since that's the case, what should we do?" Ye Xiaomei asked.There was a conflict between the neighbors, and the scope of influence was not limited to that time. I am afraid that there was hatred in the three generations.

"I have a solution, and I need the help of Erlang and my younger sister." Jiang Zhi picked up the oil lamp and walked to the sand table: "Please, younger sister, help me get the bamboo slices."

Ye Xiaomei handed the bamboo piece to Jiang Zhi, lit another oil lamp,
"The water is in the river. We can transfer the water from the river and transport it to our fields from the air. It's just like this..." Jiang Zhi slowly drew a set of manual water pumping devices on the sand table.

Before the electric motor was produced, people were constantly exploring how to make water flow according to their own ideas.In fact, the principle of pumping water is very simple, but it is a pity that it was not as convenient as modern materials in ancient times, and everything can only be replaced.

She has been observing the river for a long time today. The flow of the river is relatively low, so the large two-wheeled waterwheel is not suitable.

The reason why the single-wheeled waterwheels in Qikuaitian Village can rotate is that they are located on a higher terrain and the river flows faster.

And because the manpower and material resources consumed to manufacture the waterwheel were too huge, and the time was too long, Jiang Zhi had to change her strategy.

From being confused at the beginning, Ye Erlang's eyes became brighter later.

This... This is simply unheard of, and it is so strange that there is such an ingenious design in the world!And this one was made by my sister-in-law.

"Sister-in-law, can it really work?" Ye Erlang wondered and then doubted.

"Let's try it out and see if it works. If it doesn't work, how about I carry water with you?" Jiang Zhi raised her eyebrows.

"How can I make my sister-in-law work hard? If it doesn't work, Erlang will fetch water." Ye Erlang gritted his teeth and made up his mind that he would make his sister-in-law's drawing.Jiang Zhi moved the sketch on the sand table to the straw paper, and then began to calculate and think.
