After Zhao Tuo determined that there were no major events in Xianyang in the past two days, he made a special trip for a day to Chaoyangli, Shangyuan Township, where he had settled in the past.

The carriage passed by, and I saw the lush vegetation and flowers on both sides of the road, showing the vibrant scene of spring.

In the farmland on both sides, there are many farmers who are working hard inside, ploughing the land.

From time to time, you can still see ploughing oxen pulling plows in the fields, turning the ground and raising the soil.

Cattle ploughing was very common in the Qin State, and the Qin government even set up a special law to protect the ploughing cattle.

As far as Zhao Tuo knows.

In the townships of the Qin State, the cattle were evaluated every quarter, and if the cattle were raised well, the relevant cattle managers would be rewarded with wine and meat, and the cattle breeders would be exempted from servitude. If the cattle are not raised well, they will be reprimanded by the superiors and fined for their achievements.

And if you use cattle to plow the fields, you must be more careful to control them, but you must not tire the cattle down.

If the waist of the ox is tired and thin, then for every inch of thinness, the principal should be whipped ten times, if the ox is used excessively, so that the cow is too thin, then it is possible that the person who uses the ox will be beaten to death.

In addition to the maintenance of cultivated cattle, Qin Law also has requirements for cattle breeding.

If six of the ten adult cows do not give birth to calves, then they are punished with a husband and a guilder on the left.

So the husband has to think of a way to breed the cow every year, otherwise he will have to pay a fine.

In addition to the township, each county has to assess the cattle every year, if three out of ten cattle die, including the cattle raiser, the official in charge of the cattle, and even the county order and county governor who go up to the county are guilty and need to be held accountable and punished!

Therefore, even if it is the chief official of a county, the county magistrate who is high in the county government, he has to raise more cattle on weekdays. Maybe a cattle breeder made a mistake, not to mention pulling down the county order, at least a note on the file, and it is unlikely that he wants to be promoted.

The reason why the protection of cattle is so strict in the laws of the Qin State is that cattle ploughing is too important, which can greatly save manpower and improve the efficiency of ploughing the soil, which plays a very important role in agricultural production.

In Zhao Tuo's eyes, the popularization of cattle farming in the Qin State was good, and it was a relatively advanced production method compared to the entire era. But there is still room for improvement, for example, the plough used in the ox ploughing of the Qin State is basically a long straight plough, which is not flexible enough to turn back when ploughing, and the soil is more laborious, and the efficiency is not very high.

And he knows exactly what can solve this problem.

The house where Chaoyang Riyoko lived.

Since Zhao Tuo moved to Xianyang City, all the houses and acres left here have been given to Heng. Including Zhao Tuo's subsequent promotion, the rewards of acres issued by the government were also required by Zhao Tuo to continue to be distributed near Chaoyangli for agricultural experiments.

Zhao Tuo took Lu Juan and Zhong Liyi into the hospital under the respectful greeting of the Heng family.

I don't know if it's because I got married, or because I worked too much in the field, I'm a lot thinner than last year, my face is yellow and black, and I'm an old farmer in the field.

[Stable operation for many years, comparable to the old version of the book-chasing artifact, old bookworms are using.]

The craftsman who made this thing was also intimidated by him in the name of Zhao Tuo, so that he did not dare to speak nonsense.

Heng quietly experimented in the field, and he also asked his wife Jing to let the wind out nearby to prevent it from being seen by others.

"You're doing a great job."

Zhao Tuo bowed slightly, it is indeed more reliable to do things horizontally, and the confidentiality work is done very well.

He turned to look at the iron plough in the warehouse.

Whether something is good or not, you still know when you use it.

Half an hour later, in the farmland under Zhao Tuo's name, he watched under the manipulation of Heng, ploughing the land with the strange-looking iron plough pulling the ox.

Compared with the long straight plough seen on Zhao Tuo's road, it is difficult to turn around when plowing the land, and it is quite laborious.

The plough that comes out horizontally is not only smaller and lighter, but also after the wheel is changed from a straight wheel to a curved wheel, it is more convenient to turn around and turn, and the operation is very flexible, so that the time to finish plowing an acre of land is greatly shortened, and the area of the field cultivated in one day is greatly increased.

Zhao Tuo estimated that the Quyuan plough in the later generations may be slightly different from the things in front of him in terms of specific small parts. But roughly it shouldn't be much worse, after all, the curved wheel, the curved wheel, changing the long straight wheel to the short curved wheel is the biggest progress.

Moreover, it is still a rough product, if the skilled craftsmen of Shaofu are allowed to improve on this basis, it will definitely become more useful, and the efficiency of cultivated land may be further improved.

Zhao Tuo thought that if this thing could be promoted to the entire Qin State, it would definitely speed up the spring plowing speed of the Qin people a lot, so that more manpower, animal power and time could be freed up to do other things.

This thing is a militaristic weapon!

"Very good, it is a great achievement for you to make this thing, and I will definitely ask for credit for you in front of the king."

Zhao Tuo was very happy, patting Heng's shoulder and praising constantly.

He hurriedly said, "This thing is what a gentleman thinks, and if there is no sketch and point drawn by a gentleman, there is no reason for this thing to be born. Everything is the work of a gentleman, and if you can do things for a gentleman, you will be satisfied, and you can let a gentleman ask for credit for me."

Zhong Liyi and Lu Juan were both surprised, they had already seen the effect of Quyuan plow, and knew that this thing was very useful for farming, so they were secretly surprised that Qin State had such a sharp weapon.

Now listening to the "horizontal" thing, this thing was actually thought up by Zhao Tuo, and the two of them looked at Zhao Tuo's eyes and couldn't help but become more and more surprised and respectful.

This Zhao Jun is not only good at fighting, but also skilled in farming? ….

In the face of Heng's humility, Zhao Tuo laughed: "Do you have any credit, I don't know? Don't underestimate this thing, once this thing is made, if it is popularized in the world, it will be no less effective than the method of manure in the past."

Thinking of this, Zhao Tuo couldn't help but raise his head, look at the sky and smile.

The proudest thing about Zhao Tuo coming to this world is not to speed up the unification process of Qin, nor to change the original historical trend, but the advanced technology he brought.

The method of manure.

Quyuan plow.

Increase grain yield per mu and improve production efficiency.

In the next year, 10 years, 100 years, or even 1,000 years, countless people will benefit from these technologies he brings, and I don't know how many people in this world will get a chance to live because of this.

Zhao Tuo thought of the great famine he experienced when he first came to this world.

Eating bark and grass roots, digging for dirt to fill their stomachs, and even many people looking at the corpses of their own kind with sinful eyes.

"May the people of the world never suffer from hunger again."

Zhao Tuo muttered, this was his wish.

……

In Xianyang City, after Zhao Tuo returned, he immediately reported the matter of Quyuan plough to Qin Wangzheng.

Unlike his previous method of reporting the fertilizer and still needing the princess to speak for him, now Zhao Tuo, as a middle and higher lord, not only has the right to discuss politics in the court, but also can directly write to the King of Qin, without going through the mouth of others.

Qin Wangzheng really attached great importance to this, and when he saw Zhao Tuo's book, he immediately summoned him into the palace.

"You said that the Quyuan plough you made is more efficient than the Qin plow? Can you speed up farming?"

"Yui."

Zhao Tuo responded, and then began to explain the role of the Quyuan plow.

As for the origin of this plow, Zhao Tuo pushed it to the former farmer according to the custom.

It was said that he had seen the farmer's people use it before, and vaguely remembered the general appearance, so he asked his subordinates to conduct manufacturing research, and it took a whole year to get the Quyuan plow out, and only after confirming that it had an effect did he dare to give it to the king.

Of course, he did not forget to praise Heng's merits in front of the king.

"Farmhouse?"

Qin Wangzheng stared at Zhao Tuo with a smile: "First is the public equipment, and then the farmer's technique. The method of manure, the plough of the curved yuan...... Hehe, Zhao Tuo, you remember the events of your youth quite clearly."

Zhao Tuo's face was full of embarrassment.

Fortunately, Qin Wangzheng did not ask about this matter, and the king was more concerned about whether the things offered by Zhao Tuo were useful.

As long as it is beneficial to the Qin State, no matter where it is obtained, it is a good thing and a credit.

"Send that thing to the Shaofu, and when you are sure that it is useful, let the Zhisu Inner History Mansion promote this thing. At that time, you Zhao Tuo and that horizontal credit will not be less."

King Qin opened his mouth.

Zhao Tuo hurriedly bowed and retreated.

He didn't really value the credit for it.

After all, Zhao Tuo's title has reached the middle level, the title is too high, and it is no longer a quantil plough that can make him upgrade, if you want to be promoted quickly, you still have to rely on meritorious service on the battlefield.

The greatest use of this thing is to enhance the national strength of the Qin State.

Watching Zhao Tuo's figure leave, Qin Wangzheng thought of something and asked people to invite Yao Jia.

"The King."

After Yao Jia entered, he hurriedly bowed and greeted.

Qin Wangzheng nodded slightly, didn't say much nonsense, and asked directly, "How is Xiang Yan Xiongqi's matter?"

Yao Jia smiled slightly, and arched his hand: "Your lord, calculate the time, the rumors should spread in Chu soon. Under the deliberate promotion of the people of the Qin Kingdom, I think that the entire Chu State will know that Xiang Yan has the heart of Xiong Qi, and it will be up to him to see how he responds to it."

"Good."

Qin Wangzheng smiled coldly.

He looked in the direction of Jing Chu in the south and whispered, "Xiong Qi, Xiong Qi, do you think that you have betrayed the widow and will be able to live in peace when you return to the Chu Kingdom?"

"The Negative will let you know that there is no king in the world who trusts you more than the widow."

"You'll regret it......".
