Dian Nong School Lieutenant Yamen, in the study.

Guan Ping sat on the main seat, Zhang Yu took Deng Ai to sit next to Guan Ping, Deng Ai usually likes to stay in Guan Ping's arms, but at the moment he is kneeling and sitting in a proper manner, looking very well-behaved.

But before that, Zhang Yu taught him the rules.

His mother was fierce, and he listened to his mother very much.

Liao Ning knelt on the guest seat, this is Liao Hua's cousin, his appearance is very delicate, with a long beard, tall and thin, and his temperament is extremely soft.

Ma Liang once said that Liao Ning is very patient with children. Preconceived, Guan Ping saw this person's soft temperament again, so he put his mind at ease.

Asking a child to be a teacher is not the same as apprenticing. The teacher in charge of enlightenment does not need to be very good at learning, just be patient.

"Sir. Ma Jichang should have made it more clear in the letter, so I won't say more. This is my son Deng Ai, only three years old, but smart and clever, only a little stuttering, please be considerate of him. Guan Ping pointed at Deng Ai and said very politely to Liao Ning.

"Don't worry, my lord, since I have accepted this errand, I will definitely do my best." Liao Ning said very seriously. Guan Ping was satisfied, so he said to Deng Ai: "Ai'er, why don't you go and see Mr. soon?" ”

"Deng... Ai, Ai see... Mr. Guo. Deng Ai has been taught by Zhang Yu, and at this moment he stood up respectfully, came to Liao Ning and knelt down, kowtowing in a milky voice.

It's just a stutter, and I really can't fix it.

Liao Ning accepted this kneeling salute deservedly, and then asked Deng Ai to get up. After that, Guan Ping asked Zhang Yu to hug Deng Ai down, and then talked to Liao Ning about the issue of Yulu and Deng Ai's education.

The question of Yulu is necessary, and the teacher is specifically responsible for enlightenment, which is equivalent to the later Mr. Xixi, who specializes in enlightening children.

These gentlemen live on a living on a slur, on the contrary, if they visit a famous teacher, they need to be tied.

After negotiating everything, Guan Ping asked Ding Feng to arrange Liao Ning's residence, as for the rest, there is no need to think about it, because Liao Ning not only came by himself, but also brought two entourages and a maidservant, and Guan Ping didn't need to worry about daily life.

This matter is very important in Guan Ping's opinion, this is related to Deng Ai's education, and after Deng Ai's enlightenment, when he was thirteen or fourteen years old, Guan Ping still needed to find a good teacher for Deng Ai.

After doing this, Guan Ping was also relieved.

And since this matter has been done, he is far away from Xinye, and Zhang Yu is by his side, who is not only responsible for eating and living, but also responsible for warming the bed at night.

Guan Ping lived in seclusion in the lieutenant department of this agricultural school, practiced martial arts, inspected the territory, and when he was interested, he lifted his clothes and went to dig a canal, and his life was plain but fulfilling.

Now Guan Ping is only waiting for the quyuan plow and the new waterwheel to come out. After another half a month, there was good news from Ma Sheng's side.

With the increase in population, the Yamen of the Diannong School can no longer accommodate so many people. Ma Sheng and other craftsmen built an earthen house outside the yamen of the Lieutenant Department of the Diannong School to live.

Guan Ping got the news and came to the outside of the earthen house.

Guan Ping not only came by himself, but also brought Ma Liang, Sun Qian, and the Ding family brothers, needless to say.

A large group of people gathered around, watching Ma Sheng perform. I saw that Ma Sheng was holding a special plough in his hand, which was more special than the straight plough he was using now.

Its beam is curved, so it is called a curved plow.

"As the captain said, this plough is very light and flexible when turning, and you can also choose deep and shallow ploughing, which is very easy to operate. It can greatly save manpower and animal power. Ladies and gentlemen, please take a look. Ma Sheng not only explained, but also carried out the operation on the spot, he led the people to the open space in front of the earthen house, and let a craftsman pull the plow forward in front, and he held the plow behind.

Ma Liang and Sun Qian all know how to farm, that is, Ding Feng, and the Ding Feng brothers often participate in labor.

This is not as convincing as the physical operation.

Ma Liang, Sun Gan and others knew the difficulty of plowing the field because they knew how to plow the field and had seen the ploughing field.

Not to mention that the curved plough can adjust the depth of the plough, which is a great convenience for farmers.

It can allow a smaller number of people to open up more fields.

That is to say, these 5,000 strong men could have cultivated 40,000 mu of land, but now they can cultivate 50,000 mu, or even more.

If it's placed in Xinye, it's even more remarkable. Because the population in Xinye City is now about 100,000, plus the army, and the population outside the city is also more than 100,000, and the population outside the city is basically all farmers.

If this plough is applied to the people, the benefits will be greater.

Ding Feng and Ding Feng brothers were also quite excited, because after the two brothers followed Guan Ping these days, they began to study the art of war, and the first thing in the art of war is to go first before the soldiers and horses move the grain and grass.

Only with enough food and grass can a large-scale war be waged.

It's like the Northern War.

At that time, the princes rose together, the world was in chaos, and countless princes perished, and the reason for their demise was that there was no food, and the army itself was defeated and perished, just like Yuan Shu.

It wasn't until Cao Cao carried out Tuntian that his strength grew rapidly, and he finally defeated Yuan Shao, the overlord of Hebei, and became the number one in the world now.

This plough is used well, and it can be used by more than 100,000 farmers in Xinye as 200,000, which is really of great significance.

Ma Liang and Sun Qian are both civilian officials, and they are also military, and they know the stakes and interests, and they are all overjoyed, only Ma Liang, who is happy at the same time, but also a little worried.

"Hahaha, okay, okay." Guan Ping laughed, and couldn't help but be happy with his palms.

Soon after, the two people who were helping the plough and Ma Sheng, who were pulling in front, stopped plowing the field, and Guan Ping asked again: "What about the waterwheel, but it has been built?" ”

"Returning to Lord Lieutenant, it's also done." Ma Sheng also had a heartfelt smile on his face, as a craftsman, he didn't really understand the value of these things, but he knew the immediate benefits.

As long as the waterwheel was improved and the Quyuan plow was invented, Guan Ping promised to give each of them two gold, which was definitely a huge amount of money for a craftsman like Ma Sheng.

Thanks to the ideas provided by the little prince, not only the Quyuan plow has been built, but even the waterwheel has been improved.

When Ma Sheng spoke, he invited Guan Ping, Ma Liang, Sun Gan and others to come to the side of the canal, this wasteland has countless acres, and the current troops have built a vertical and horizontal canal on about 40,000 acres of land, and this canal is only one of the sections.

It's still spring, the water level is relatively low, and there is less water in the canal.

At this moment, there is a waterwheel in the canal, this kind of waterwheel is very common, it is a thing that leads water from a low place to a high place, also called a rollover, a keel waterwheel.

There are foot pedals, hand cranks, etc., and this waterwheel should be pedaled.

Ma Sheng personally demonstrated, holding the crossbar with both hands, stepping on the wooden plank with both feet, stepping down hard, with the use of strength, the template in the sink began to move, pulling the water in the canal up, the efficiency was very fast, only to see that there was constantly turbid water, spit out from the sink, and fell to the ground.

After Ma Sheng demonstrated for a while, he walked down, bowed to Guan Ping, and said sincerely: "There are waterwheels in this world, but the idea provided by Xiaojunhou can increase the amount of water spit by fifty percent. Manpower is saved. There are many kinds of rice in the south, and the storage of rice water is very physically demanding, and with this waterwheel, it is much more convenient. Combined with the use of curved plows, you can get twice the result with half the effort. ”

This is from the bottom of my heart.

Although Ma Sheng didn't know what impact the invention of these two things would have on the war and the world. But he knows that for a farmer, it is easier to complete the work, save physical energy, and cultivate more acres.

That's a really good thing.

"Okay, okay." Guan Ping smiled, and then said to Sun Gan: "Wait a minute, go to the treasury and get twenty gold to distribute to ten craftsmen, and then take hardware and reward it to Ma Sheng." ”

"No." Sun Gan has no meaning to this, these two things were created, and the benefits are eternal, not to mention the reward of this bit of gold and silver, Sun Gan thinks that it is nothing to be a marquis.

Of course, this is mainly Guan Ping providing ideas.

Even if you are a marquis, you should also be a marquis.

Thinking of this, Sun Qian had to feel nostalgic. Why didn't you notice that this stinky boy was so smart and had so many ghost ideas in his head?

Distilled spirits, horseshoes, stirrups, curved ploughs, waterwheels, and so many other inventions, not to mention the appalling countermeasures.

First take Jingzhou and Yizhou, and then wave the army to the north to revive the Han Dynasty.

Recalling the scene that happened in the lobby that day, Sun Qian still feels his blood boiling.

At this moment, Sun Qian felt that the strategic goal was more hopeful to be achieved.

"Hahaha." Guan Ping was very happy and couldn't stop laughing. But suddenly he saw that Ma Liang seemed to have a worried look on his face, and he couldn't help but feel surprised.

It's obviously a great thing, why am I so worried?

Guan Ping originally wanted to send these two things to Xinye immediately, and ordered craftsmen to make them day and night and sell them to the people of Xinye to improve production efficiency.

But when he saw this, his heart moved, and he didn't make a decision in a hurry. Guan Ping smiled and asked Ma Sheng and the others to go down to rest, and then took Sun Qian, Ma Liang, Ding Feng, Ding Feng and others back to the Yamen study.

Guan Ping asked Ding Feng and Ding Feng to guard outside the study, and led Ma Liang and Sun Qian to come in and sit down. After sitting down, Guan Ping asked bluntly: "Ji Chang, you seem to be a little worried?" Why is that? ”

"Worried?" Sun Qian was also very strange, he was also immersed in joy just now, and his observation was not as careful as Guan Ping's, and it was naturally very strange to hear it at this moment.

This is a great thing, how can you worry?

However, Sun Qian has a very high opinion of Ma Liang, this Ma family's white eyebrows are really very good, although he is young, but he is in charge of the six or seven thousand people in the lieutenant department of the agricultural school, which is very easy.

Military, people's livelihood, punishment, all kinds are involved, and they are all proficient.

Compared with his talent, Sun Qian is ashamed of himself.

Therefore, Sun Qian was very relieved to hand over all the big and small affairs to Ma Liang, retreated to the background, and was very idle at present.

Why is Ma Liang worried?

Sun Qian was also curious.
