Liu He's demonstration was over, and he sat on the ridge and watched the old farmers try the Quyuan plow one by one with a smile on their faces, and his heart was calm and joyful.

However, when he first came to Dahan, he was actually desperate, because he found that in this era, trying to make things like steam engines, internal combustion engines, and rifles is tantamount to building wonders.

Especially when he learned that the Han Dynasty had not even popularized the iron pot, he completely broke off this leapfrog development model, and focused on some technologies that can really be realized at the moment, and gently promoted the progress of society.

What's more, from the straight plough to the curved plough, the span is already very large, and the real curved plough did not begin to be invented and used on a large scale until the Tang Dynasty.

Since then, there has been no further development for more than a thousand years, and even in the era where Liu He once lived, in the most remote villages, there were still peasants using the same labor tools as the zigzag plough in front of them.

The development of a nation is calculated over thousands of years, and Liu He, as a person with a limited lifespan, cannot grow up with this nation, and can only give it some impetus at a critical moment to make it grow faster and better.

The predecessors planted trees and the later people enjoyed the shade, as for what direction will be in the future, it is up to all the people to decide.

The sun is slanting in the west, the river breeze is cool, the insects are chirping, and the moon rises.

Liu He saw that the old peasants were becoming more and more proficient in using the quyuan plow, so he stood up from the ridge, patted the mud on his buttocks, and called Wang He not far away.

"Will they all use it?"

"Back to the door, the big guys will use it."

"What do they say?"

"It's easy to use, the plough is not only fast, but also can adjust the depth before the front, the big guys say that with this kind of curved plow, a family of three can grow 30 acres of fields a year."

The ten acres of land in the Han Dynasty are equivalent to the seven acres of land in later generations, and in the most extensive way, there are three families with strong laborers who can cultivate about 100 acres of land, and in a good year, they can harvest 300 acres of corn, which is about 8,500 catties of raw grain with skin in later generations, and this income is not low in terms of numbers, and the income of an official with a rank of 200 stone is on par with Lu.

However, the actual situation is not as wonderful as the theoretical data, and the biggest reason for this gap is that farmers do not have 100 acres of land in their hands.

The Han Dynasty did not have a law of granting land, and there were only three ways for farmers to have land to plant.

The first is the conferral of military merit, and you can get land when you get a knighthood.

The second is the tenant landlord's land, which is then firmly bound to the land and forms a dependent relationship with the landlord.

The third is to open up the land for farming, as long as it is registered according to the law, the Han Dynasty recognizes that the land is privately owned.

The first method of acquiring land is not only to look at the time, but also to look at the opportunity.

The latter two methods thus become the most common methods of obtaining arable land.

The biggest disadvantage of leasing landlord's land is that it bears high ground rent.

At this time, the land rent collected by the Han court was 15 tithes, which was not heavy, but the tenant rent collected by the landlord was very high, and half of the tenants' annual harvest had to be handed over to the landlord.

A family of three worked tirelessly for a whole year, and after paying the rent, they left the grain for the next year, and after removing the food and clothing expenses for another year, there was not much left.

You can't save money to buy good land at all, you can only be tied to the landlord's land for the rest of your life, as their vassals.

Then, if the peasants want to turn over and get rid of the control of the landlords, there is only one way left to open up the wasteland and cultivate the land.

Only by improving labor efficiency can we have extra time and energy to open up wasteland.

Just like Wang He just said, the use of Quyuan plough can allow a family of three to cultivate an additional 30 acres of land, which not only means that the people can harvest more than 30 acres of land, but also means that there are 30 acres of production materials - of course, the cultivation of land is not completed in a year, it takes time to slowly realize.

And Liu He not only wanted to increase the harvest of the people and farmers, but also to use this way to fight against the biggest hidden killer of the feudal dynasty - land annexation.

After the fall of Emperor Xiaowu, the situation of land annexation has intensified, and the number of yeoman farmers has been decreasing, although it has not yet reached the point of being out of control, but if it is not stopped, then history will definitely repeat itself.

In the end, there will definitely be a situation where the strong and the strong rise, the gate valve is raging, and the strong branches are weak.

The Birth of a New Empire – The Glory of the Empire – Land Annexation – The Decline of the Empire – The Birth of a New Empire.

This dynastic cycle has been played out countless times in Chinese history, and this beginning is naturally the Han Empire.

This is what Liu He doesn't want to see, and it's what he wants to change.

To solve this problem, one is to increase productivity, and the other is to promulgate laws to curb mergers.

Liu He is currently only the king of Changyi, so he can only start with the first thing now.

In the past two years, from the cocoon to the seedling horse, from the overturned car to the vertical well water wheel, from the substitute cultivator to the curved plow...... Liu He brought out these advanced and traditional agricultural tools one by one in order to improve productivity.

With the help of these new farm tools, the life of the people of Changyi is much better than before.

In Liu He's mind, there are still many farm tools to be moved out one by one.

"Thirty acres of land is not a small amount." Liu He said to himself.

"The great kindness of the people under the door will never be forgotten by the people of Changyi," Wang He said very seriously this time, without a little flattery and perfunctory.

"Then talk to the engineer and find the right workshop and craftsman to start making more of these farming tools."

"Under the door, the subordinate has a sentence, I don't know whether to say it or not......"

"Well, but it doesn't hurt to say that."

"In the past two years, the farm tools made by the door for everyone add up, at least dozens of pieces, why don't you build a workshop in the palace to make and sell these farm tools, these farm tools are mostly wooden, not in the scope of salt and iron monopoly."

"Don't blame the little officials for the philistine, the big Han is not only my Changyi country, although these farm tools are easy to imitate, but if they can be sold first, they can still make a lot of money."

Wang He said these words very smoothly, and it seemed that he had been thinking about it for a long time before asking.

"If the people of Changyi are doing well, that is, I am doing well, let the craftsmen earn this money, and in the end, don't they have to pay taxes to the palace?"

Wang He seemed to have some understanding, and the suspicion on his face dissipated a lot.

"In addition, Wang Cao Shi has a sentence that is very true, the Han is not only my Changyi country, as a prince and king, I should share the worries of the county officials, after all, the world of this Han is the world of my Han after all."

"Let the people of the world live in peace, so that the Han Dynasty can be passed on to all generations, and my Changyi country can be passed on to all generations."

"What's more, aren't those craftsmen also the people of my Han Dynasty, who don't compete with the people for profit, and those who die well are many, and those who are not good are few."

Liu He said directly and tactfully, Wang He only understood one of the meanings, he took two steps back, and made a big bow in a dignified manner.

"There is virtue under the door, and the subordinates admire."
