The so-called curved plow is actually not very different from the straight plow used before. It is just that the original straight plow is changed to a curved plow with a curved plow with a curved plow, and then a plow plate that can rotate freely is installed on the head of the shaft.

But such small changes greatly reduce the amount of labor on arable land.

First of all, the freely rotating plow plate is very convenient for turning and turning, so that there is no need to lift the plow every time when tillage; secondly, the short and curved plow frame makes the shaft pressed very low, and the traction force and soil resistance tend to be almost in a straight line. The fundamental theorem of physics makes this design easier to achieve the balance of two forces.

The previous straight plow was too high, so the traction force was dispersed into horizontal and vertical forces. During farming, it wasted not only animal power, but also manpower to work hard to press the plow arrow into the soil, and half the result was achieved with twice the effort.

However, Li Hao was not prepared to explain too much about these pure theoretical knowledge. It was not that he didn't want to say it, but that it was too troublesome to explain it.

The three elements of force plus the stress analysis and trigonometric function cannot be finished in less than three or five days. Instead of trying all the talk, it is better to directly insert the curved plow into the ground and take a walk.

In the fields next to the official road, there was a family of farmers working hard. An old man in his fifties was holding a cow in front. Two young men behind him struggled to control the straight plow that had been spent for a long time. Behind him was a hunched woman, who was carrying a young baby, planting seeds while cultivating soil.

The family had already noticed Li Hao and his group on the official road. When they saw them walking down the official road, they stopped their work, squeezed together with their eyes lowered. Only the young doll, who was ignorant and fearless, raised his little head, opened his mouth, and stared at Tiezhu blankly.

Li Hao reached out and rubbed the little brat's head, turned his head and said to the old man, "Old man, are you busy?"

"Oh, busy, busy." The old man nodded mechanically, a little at a loss.

All the young people in front of them were gorgeous clothes and extraordinary demeanor. Compared with these people, the rich and powerful people in the village were even worse than cow dung.

The big man carrying a strange-looking plowing plow, his two usually strong sons were almost the same as little bean sprouts in front of him. I don’t know what they had grown up with. I guess if his family ploughed the land, they would save even the cattle.

Just as he was thinking about it, Li Hao said, "Old man, I want to help you do me a favor, I don't know if Fang is inconvenient."

"Convenient, convenient! If you have something to do, just say it. I will do my best." As the head of the family, the old man did not ask for the opinions of his two sons, and pressed his two sons with red faces behind him.

An ignorant thing can't tell the difference between eyebrows and eyes.

Although these young people look not old, can they just refuse the nobleness?

My family is just an ordinary nonsense person. I can do whatever they ask me to do, and there are so many things.

The hunched woman was also pulling two sons at any time and ready to rush out, for fear that they would hit these big men they could not afford to offend.

She has lived at the lowest level of society all her life, and she has accepted her fate.

If you are bullied, you should be bullied. This is the way of the world. Just bear with it and go through it.

The two young men who were stopped by their parents turned red in an anxious manner, their mouths opened and then opened, pointing at Li Hao, they couldn't even say a word.

Li Hao did not show any surprises. At least Tiezhu was standing next to him. The two young people really didn't have enough time to rush up to him, and it was okay.

He smiled faintly, pointed to the curved plow in the iron pillar's hand, and then pointed to the old man's straight plow: "Old man, do you think I'll use this to exchange for your one?"

"This..." The old man hesitated, and a trace of reluctance flashed in his eyes.

Although the plow is a bit old, it has been used for a few years and has been rashly changing to a new one. Who knows whether it is easy to use? If it is not easy to use, wouldn’t it delay the spring plowing?

But if they don't agree, will these people...

Before the old man could figure it out, the two young people who had been pressed behind him finally recovered and shouted at the top of their voice: "Switch, let's change, Mr. Hou, we change!"

"Just to say, I'm not dead yet, how can you be the leader?" "The old man just heard that his heart was like a knife, and he turned around and slapped one of his two sons in the face.

After the fight, I felt something was wrong and was stunned: "You, who did you just shout?"

Although the two young men were sore about their faces that they were thrusting, they didn't care at this moment and tried their best to point behind the old man: "Dad, Mr. Hou, it's Mr. Hou, Mr. Hou, Mr. Li."

"What Master Hou, Mr. Ma, are you two crazy?" The old man had just scolded his son, and his face suddenly became more exciting. He turned around little by little, and shouted tentatively: "Mr. Li Hou?!"

"It's me." Li Hao nodded with a smile.

Changsun Chong and others beside him followed and started to cheer: "Isn't it him? The Wanjia Bisheng Buddha in Bingzhou, I heard that many people want to build a temple for him."

After confirming Li Hao's identity, the old man who was originally quite calm immediately kicked the two hind legs like a chicken blood, pulled the little kid with calloused hands across the silly husband's little kid, pinched the back of the neck and pressed it to the ground.

"Mr. Hou is here, the old man and his family kowtowed to you!"

Li Hao never thought that he just wanted to try the curved plow that would cause so many twists and turns. He rushed forward and supported the old man: "It's not possible, it's not possible, my father-in-law, you're reducing my life."

Changsun Chong and others on the side didn't care about joking, and went forward to help the little kid and the woman up.

The old man was supported by Li Hao, and his whole body was trembling with excitement. He glared at his two sons who didn't know whether to kneel down. He raised his foot and wanted to kick him again: "You two are not good-for-nothing people, Mr. Hou is our family's savior. What's wrong with you two kowtows? Why don't you kneel down quickly!"

Li Hao was confused. From beginning to end, he didn't know when he had saved this family.

Seeing that the two young people were about to kneel down, Li Hao, who was not very comfortable with this situation, quickly asked someone to support them, and said to the old man vaguely: "Don't, old man, really don't need it. This is what I should do. When I was in Chang'an, Your Majesty often taught me to take it from the people and use it for the people, so I have to thank you, so thank you for having a good Majesty."

"Hey, hey, okay, okay!" The old man could not understand what Li Hao was saying. He only nodded constantly. Suddenly, he seemed to think of something again. He ran to remove the straight plow tied to the cow again: "Mr. Hou, this is the plow you want. I will give it to you for free, so I don't need to change it."

Li Hao smacked his lips, unable to laugh or cry.

What do I want to do with a broken plow? Go back and flip the yard for Liu Feng?!

"Old man, you should keep this plow yourself, I don't need it."

"Ah?! Why? Master Hou, the old man didn't know it was you before. There were many collisions between his words, so don't be surprised."

Li Hao smiled bitterly: "Old man, I'm not surprised, I really don't need this plow... I'm... Oh! Let me say that, I have a special plow stick in my hand. Can you help me try it and see if this plow works well?"

"Try the plow? No, no problem. It is a blessing for the old man to try the plow for my husband." The old man said, looking at the plow that was held in his hand by Tiezhu, his eyes a little strange.

If you try the plow, you have already said that, why do you want to change it? I was so scared that I thought I was going to rob my plow.

To put it short, with the help of the old man's family, the curved plow was quickly installed.

It was just because of the design that there was no room for a second person to operate on the curved plow, so the old man and his family were helpless, and the two young people were even more anxious.

Seeing this, Li Hao had to say to them: "Let's use this first. We only have one person. If we can't pull it, we will study how to operate the second person."

With Li Hao's explanation, the old man's family felt much more relaxed. After whispering, the old man was still the one who was tall and the two younger generations, who were more mature, were responsible for supporting the plow.

After opening the rack, the old man shouted, and the young man who was holding the plow behind him screamed strangely: "My mother, this plow is too light!"

Qing? The old man didn't understand what it meant. He led the cow and continued to walk forward, and turned around and took a look.

It doesn't matter when it looks like this. The old man who thinks he is a good farmer almost pops his eyes out.

I saw my eldest son, with his hands on the plow, as if he was walking easily, but the very strange-shaped plow did not have the same forward tendency as before, and he just kept moving slowly along the direction of the ox.

Is this a joke? When did the plow get so relaxed?

In the past, my two sons could only hold the plow together.

The old man felt stranger the more he looked at it. In the end, he simply stopped holding the cow and went straight to the back and said to his eldest son: "You go ahead and pick the cow and I'll help him."

The eldest son looked reluctant: "Dad, it's okay, I can help you, you should keep it."

The old man glared and showed off the feudal parents' style: "Stop talking nonsense, I will go if I ask you to go."

Yin Wei, who was photographed by the old man, drooped his head and muttered something, and he ran to Changniu unwillingly.

When the plow rod moved again, the old man finally understood why his eldest son didn't like to go to the ox.

Because the plow is really light, just walk behind and just gently support the direction, and you don’t need to use too much force.

Relatively speaking, walking ahead is much more troublesome. Not only do you have to control the direction of the cow, but you also have to force the cow to move forward. No wonder this kid doesn't want to go to the cow. It turns out that the root is here.

After walking, the old man soon ended. The boss who was standing in front of him turned around and planned to help the old man pull out the plow and insert it again.

As a result, the old man waved his hand and looked serious: "No need to worry, you should turn around with the cow first. I see that the plowshare seems to have some flower heads, so it should not delay the turn."

Facts proved that the old man guessed correctly. When the new plow turned, he did not need to pull out the entire plow as he did before. Not only did he save effort, but he also saved a lot of time.

Artifact, this is a artifact!

It turns out that what Mr. Hou uses is really different from what ordinary people use. No wonder Mr. Hou looks tender and tender. It turns out that he doesn’t have any effort to cultivate the land at home.

The old man was full of envy for Li Hao, but he had no idea of ​​taking the plow for himself. He thought about it all the way back. When he reached the position he wanted to meet with Li Hao and others before, he found that there was no one else on the ridge of the field except his wife, second son and third son.

The old man suddenly panicked and shouted nervously: "Damn, where is the man Hou?"

"Let's go!" The woman with a hunched back smiled and said while teasing the little kid.

"Leave?" The old man looked at the plow in his hand, and his mind was confused: "What, why are you leaving? This plow is still here."

"Dad, Master Hou said he's giving it to us."

"I've given us..., such a good plow... I've given us? Didn't you lie to me?" The old man's voice unconsciously rose octaves.

"There is still a false statement, Mr. Hou said it in person." The woman said happily.

Just now, she saw her man and son cooperate with each other and only spent half of the time pulling a plow, and she had already understood the quality of the plow.

After repeated determination, the old man finally believed that this easy-to-use plow was indeed given to him by Li Hao. He was overjoyed and simply stopped helping the plow. He sat on the ridge of the field and played with his wife. The great cause of arable land was handed over to his two "unprofitable" sons.

One day, two days ago, the news that the old man had obtained the Shenli quickly spread. Many people from the surrounding villages came to see him, intending to see the Shenli.

Just five days later, imitations of Quyuan Plough began to appear and quickly occupied the market. In just half a month, it became popular to almost every company.

With the popularity of the curved plow, another group of people without property left the control of the gentry, signed contracts, rented farm tools, and opened wasteland, becoming a new landscape in Taiyuan City.

The gentry who are used to making trouble was really stunned this time. In the past, they felt that the government did not dare to do anything to them. When they made a fuss, someone would come out to speak softly to them, apologize, and sometimes even give some compensation.

But now, all the tenants in the family have run away, and there is no one to farm the land.

I want to go to the government office, but because I made a big fuss a few days ago, I really can't stand it now.

If you don’t look for it, you really can’t live this life anymore. The boss’s field is so deserted. Seeing that he is filled with weeds day by day, it’s fake to say he doesn’t feel sorry for him.
