Of course, Ma Liang has worries, to be honest, Ma Liang is very surprised that Guan Ping can really create these two sharp weapons.

When Guan Ping said that he wanted to improve the plow, Ma Liang was still unimpressed.

That is the crystallization of thousands of years of wisdom, where is it said that it can be changed?

Ma Liang thinks that Guan Ping, the boss and a friend in private, is a little too taken for granted.

I didn't expect it to be slapped in the face in a few days, and it was really made.

But to make something like this, okay? On the bright side, of course, it is good, it can save manpower, animal power, and increase the acres of arable land.

In the case of war today, the population is halved and halved.

There is too much barren land to count, but the people are scarce. Such a tool, of course, is very good.

However, this reckoning is often not a superficial thing, and there are many deep accounts to be calculated.

Ma Liang thought for a while, put his butt on his heels, straightened his chest, lowered his big sleeves with his hands, and said seriously: "I heard that when the captain took out the stirrups and horsesshoes, he had a conversation with Liu Yuzhou (referring to Liu Bei)?" The pros and cons have been analyzed. ”

Guan Ping wondered when he heard this, how did he get involved in this matter? But Guan Ping was deeply impressed by this matter, and couldn't help but immediately replied: "At that time, I thought that taking out the stirrups and horseshoes would be beneficial to Cao Cao, but after the uncle's words, I learned that it was not the number of horses that restricted the development of Cao Cao's troops, but the available soldiers, as well as the baggage needed to supply horses and cavalry." Although the stirrup increased the combat effectiveness of the Cao cavalry, the horseshoe could not increase the number of the Cao cavalry. On the contrary, there are few war horses in the south, and every horse is precious, and horseshoes can reduce the loss rate of war horses. Therefore, horseshoes and stirrups are still used, but these two things are still spreading in a small area, and they have not officially stepped into the battlefield and are not known to Cao Cao. ”

Guan Ping didn't feel anything at first, but as he spoke, he understood, and his brows couldn't help but lock deeply.

When Ma Liang saw Guan Ping's frowns, he knew that Guan Ping had figured out the doorway. Ma Liang said: "Just as the captain thought, the number of Cao Cao's cavalry is not horseshoe, but personnel, but food. Cao Cao's land is vast, there are many enemies, and the population is lacking. Huainan, Central Plains, Guanzhong, and Wancheng all have heavy troops and are guarded by troops. Although there are tuntian, it is still very difficult to supply food. In the first battle of Guandu, Cao's army was almost defeated because of lack of food. Lord Captain now has such an artifact, and if it spreads, of course it can benefit the people of Xinye. But these two artifacts are so powerful that they can't be hidden. Cao Cao can know it in the second year, and if Cao Cao knows, he will definitely use it. Then Cao Cao's strength will increase greatly, and the grain, infantry, and cavalry will greatly increase. And if Xinye is too small, the profit will be small. So I don't think these two things should be used on a large scale. Not to mention the closure of the warehouse, at least it can only be used in the lieutenant department of this agricultural school, and it is strictly guarded, and the troops are not allowed to surrender, and there is a chance to escape to the north and publicize this matter. ”

After being reminded by Ma Liang, Guan Ping thought of this just now.

This is different from distilled spirits, which are still able to remain secret, bringing a huge financial income to Shinno.

The waterwheel and the zigzag plough are things that cannot be kept secret.

The same thing, used in Shinno, can benefit ten. Used in the north of Cao Cao, the profit is one hundred, or even more.

If horseshoes were added, Cao Cao could build more and larger cavalry armies.

Even if they occupy Jingzhou and Yizhou, they can only rely on the mountains and rivers to protect themselves, and the Northern Expedition is completely impossible to run rampant in the Central Plains. As soon as the infantry went out, they could have been robbed of the grain routes, leading to the rout of the whole army.

This is a serious problem.

These two things are certainly good, but they are not suitable for use at the moment. At least we have to wait for the Guan family's territory to expand a lot.

After figuring it out, even though Guan Ping was depressed, he could only say: "Order the craftsman to build these two objects secretly, and use them secretly in the Captain's Department of the Diannong School first." ”

Although a basin of cold water was poured on it, Guan Ping was still quite concerned about this matter, and asked Ma Liangdao: "With these two artifacts, in Ji Chang's opinion, more than 5,000 strong men, how many acres of land can each person cultivate?" ”

"Twelve acres." Ma Liang thought about it and gave this answer.

"From the original person who can only cultivate eight acres, to twelve acres, the manpower saved is really considerable." Guan Ping is very satisfied with this.

The matter was thus settled, and the Quyuan plow was secretly built, as well as a new waterwheel.

Soon it was March, and the weather was starting to warm up, and it was time to plow the fields and store water. Collect water first, then plough the fields.

The soldiers of the lieutenant of the agricultural school do not need to go to the ground. Every day is just training, vigilance. The person in charge of farming was more than 5,000 Cao troops.

There are a total of 10 tuns, and each tun has more than 500 people.

And these Cao army surrendered troops, but they all know how to farm, but some people can grow rice, and some people can't. Ma Liang asked those who can grow rice to bring those who can't grow rice together.

There are only ten ploughing oxen in the entire Diannong School Captain's Department, and an average of one ploughing ox is assigned to each tun, so it is still mainly ploughed by manpower, with one person pulling the plough in front and one person supporting the plough in the back.

The fields first store water, divide them into small fields, and directly use water trucks to pull up the water in the canals to fill the fields with water. Then start ploughing, and after ploughing, store the water for a few days, and then you can plant the seedlings.

The seedling work does not need to be done by these soldiers, and its own professionals do it.

These more than 5,000 Cao troops surrendered and sat in three parts, namely the forbidden department, the Li Dian department, the Xiahou Dian department, the Xiahou Department had the largest number of people, followed by the forbidden department, and the Li Dian department had the smallest number.

Xiahoudun was very popular with the army, so many of the soldiers under his command planned to flee back to the north and continue to follow Xiahoudun.

On the contrary, Li Dian, a soldier in the forbidden department, is in peace and self-control, and he has a lot to do.

Prior to this, Guan Ping asked Ma Liang to select the supple ones among the surrendered troops to serve as pavilion chiefs, lieutenant chiefs, household chiefs and other positions to manage the surrendered troops.

This is called surrender autonomy.

And set up a joint sitting system, if someone runs away, people in the same household sit together, encourage each other to report, and those who report the truth will get a Shanyue woman as a wife.

The ten tuns of the Lieutenant Department of the Diannong School are currently named from zero to nine.

Among them, the pavilion chief of No. 8 Tun is a man named Chen Hai. Chen Hai is Chinese New Year's Eve and lives in Qingzhou. He participated in the Yellow Turban when he was a teenager and later followed Yu Ban.

After the Yellow Turban Rebellion was suppressed, the Yellow Turbans did not perish, but only became a rogue. During that time, Chen Hai once had a wife, a concubine, and three children.

Later, the Yellow Turban was pacified by Cao Cao, and his wife and children were separated in the war and disappeared. Maybe the wife has already become someone else's wife.

Chen Hai didn't feel sad about this, this was too normal in troubled times. Later, he followed Yu Ban, and with Yu Ban's expedition to the east and west, he obtained many good things, and married another wife in the north, with two sons and a daughter.

Although he was defeated and captured, his family should not be implicated, and he should be alive and well for now. It's just that the wife will inevitably remarry.

Chen Hai doesn't care about this, he's used to it anyway.

Chen Hai is not attached to Ban, because Yu Ban is very harsh on soldiers, far inferior to Xiahoudun. Chen Hai somewhat understood Xiahoudun's soldiers, and wanted to flee back to the north and continue to follow Xiahoudun's mood, but it was impossible for him to flee to the north and continue to follow Yu Ban.

On the contrary, Chen Hai got by, and set his sights on twenty-five Shanyue women, hoping to succeed in one person and continue to have his wife and children hot on the kang here.

Once a soldier defects back to the north, the household, the head of the household, the chief of the household, the chief of the house, and the chief of the pavilion will all be implicated, and the household will have 20 military sticks, and the household chief, the lieutenant chief, and the pavilion chief will each have 30 military sticks.

The punishment is very severe.

Therefore, the people who became the head of the household, the head of the house, and the head of the pavilion not only did not feel superior, but they were panicked and very afraid.

All of them are keeping an eye on the people under their command, and no one must defect and implicate them.

But in Chen Hai's view, this is an opportunity.

Someone ran away and reported it, so he had a wife.

The sun was very warm on this day, and the weather was quite warm. In the spring and summer, this kind of weather is not bad. A ploughing ox pulls the plough in front, and Chen Hai holds the plough in the back.

In the entire Dian Agricultural School Lieutenant Department, there are only ten ploughing cows, and each tun can only be assigned to one, and this ploughing ox naturally fell into the hands of the pavilion chief.

It is also one of the few benefits for the pavilion chief.

Chen Hai relied on this cow and could cultivate twenty acres of land. Since he decided to go with the flow and settled down in Xinye, Chen Hai is still very concerned about farmland and works very hard.

And for this plough and waterwheel, Chen Hai was also very surprised.

Chen Hai was born in a farming family, and later from the Yellow Turban, and also worked as a Tuntian soldier, and he was very good at cultivating the fields, but he used to plant wheat, and for planting rice, it was the first time that a big girl was a girl.

This plough is the same in the north and south. The straight-curved plough is bulky and not easy to turn, and it is very inflexible to operate.

And this curved plough is lightweight, easy to turn, and very flexible to operate. The first time Chen Hai used this quyuan plow, he immediately liked it.

And calculated in his heart that with this good thing, the same family of five, two husband and wife, and three teenagers, could have cultivated thirty or forty acres, but with this good plow, they could have cultivated ten more acres.

Don't underestimate these ten acres, you can make life more enjoyable.

Compared with being a soldier, Chen Hai is more willing to be a farmer himself. He is in his thirties, and he has not had a few years to live, and of course he prefers to live a stable life.

What surprised Chen Hai even more was that the waterwheel also existed in the north, but the operation was inconvenient and inefficient. But there is no way to use it, because the north is more water-scarce than the south, and it is more difficult to divert water.

Waterwheels, despite their inefficiency, are also indispensable.

And the new waterwheel of the Ministry of Agriculture came out of the faucet with a bang, and the amount of water was simply startled by Chen Hai.

"With these two magic weapons, as long as you are willing to work hard, you won't worry about your wife and children, and life will be delicious."

As a soldier surrendered by Cao Jun and currently appointed by the Ministry of Agriculture, Chen Hai has many hopes for the future life of Xinye.
