That afternoon, Liu He was in the house with several carpenters and blacksmiths to compare how to improve the existing farm tools, the straight plow, and in order to make it more intuitive, Liu He also had two straight ploughs borrowed from the farm outside the city.

The Han Dynasty had begun to use the plough extensively, but at this time the ploughs used by farmers were all long straight ploughs, so it was not flexible to turn around when ploughing the land, and it was also very laborious to lift the soil, but the efficiency was not very high.

Liu He grew up in the countryside in his previous life, and was later admitted to a second-rate normal college, so he had a deep impression of the Quyuan plough that was commonly used in the countryside in later generations. Liu He, a history major, remembers that the quyuan plough was formed in the Tang Dynasty and popularized and used until the 20th century.

Compared with the straight plow, there are several major improvements. First of all, the straight wheel, the long wheel is changed to the curved wheel, the short wheel, and the plow disc that can rotate freely is installed at the head of the wheel, so that not only the plow frame becomes small and light, but also is convenient for turning and turning, the operation is more flexible, and manpower and animal power can also be greatly saved.

It can save manpower and animal power, which means that the same ploughing ox and a farmer can plough twice or even double the land every day after using the curved plow, and the cultivated land is easy to fertilize and store moisture because the soil is deeper, which is of great significance for increasing agricultural income.

In such troubled times, it is not enough to have an army, you must also have enough food to support the army. Otherwise, they will all eat people and eat them all, who will grow food? Because food is a matter of life and death, Liu He attaches great importance to how to increase agricultural output, and the degree of attention is even less than that of his upcoming steelmaking technology.

Under the circumstance of limited land, increasing the grain output per unit of land is undoubtedly the right way to obtain more grain, and Liu He also knows some ways to increase grain output, such as improving farm tools, such as repairing water conservancy, such as rational use of farm fertilizer, and selecting improved varieties for artificial cultivation.

Liu He was not an inventor in his previous life, nor was he an agricultural scientist Yuan Mouping, he was just a native child who grew up in a remote rural area when he was a child, so he could only rely on some memories and impressions in his mind to put forward some design ideas and suggestions for these carpenters and blacksmiths.

Although there are not many people who know the Tao, many times smart craftsmen just lack a "small spark" in their thinking, and Liu He is the guy who likes to "set fires" everywhere!

When Liu He staggered on the paper to draw the shape of the Quyuan plough in his impression, the eyes of the two craftsmen immediately lit up, and they seemed to be inspired.

A craftsman said: "My lord, judging from the pattern, if you change the straight wheel to the curved wheel, it is not too difficult, and the key problem is how to adjust the depth of the change ploughshare and adjust the direction of the ploughshare at any time during the march. ”

Another craftsman adds: "In addition to this problem, the problem is how to ensure that the plough pan is strong and durable. ”

Liu He listened to their doubts, nodded and said, "You can ask such a question, which means that you have roughly understood my request." I don't have any more suggestions on how to design the plough, but I can remind you that the main components of the plough used by farmers today are mainly wood, and only the ploughshare is made of pig iron. ”

"You don't have any worries, although you can rest assured and boldly carry out the transformation and design, I will provide all the materials needed, no matter what the final result is, I will give you food and wages!"

Several craftsmen listened to Liu He's witty words, and immediately laughed.

Liu He disagreed, and continued: "However, if anyone can design a Quyuan plough that meets my requirements, I will not only reward him with 100 acres of fertile land, but also promote him to be an official, and allow his children to enter the school to study, so that they will not have to worry about food and clothing in the future, and they will have no worries about life in life!" ”

As Liu He's reward conditions became heavier and heavier, the breathing of several craftsmen became rapid, and some people even couldn't help but want to hurry up.

Liu He saw that the time was ripe, so he left behind the last sentence: "There are many people, if you can work together to develop the Quyuan plow as soon as possible, each of you will get the same reward, and it will be doubled!" ”

Originally, a few craftsmen who were still thinking of doing their own things, after listening to Liu He's words, they looked at each other, and I looked at you, and they seemed to be weighing the pros and cons.

In ancient China, there was no shortage of all kinds of skilled craftsmen, and even some people could produce ingenious works, but they seriously lacked a spirit called "sharing skills", so that later, many advanced techniques appeared to be broken and lost, and eventually became a regret for the country and the nation.

What "pass on the man but not the woman, pass on the son but not the daughter-in-law", what "pass on the inside but not the outside, pass on the heirs but not the concubine", what "the apprentices of the church, starve the masters", all narrow and selfish thoughts, how many skilled craftsmen, apprentices and grandchildren have been delayed!

Of course, Liu He still has a long way to go if he wants to change the closed and precautionary thinking of this technique that prevails among the handicraft crowd, and it can't be changed in a day or two. But whether it's difficult or easy, Liu He was thinking about this problem in his heart, and he quietly started to try, which is good!

After explaining to the craftsmen, Liu He was about to go to the Taifu Guard Battalion, but saw Sima of the East Gate Army riding a horse and rushing over with a happy face.

"Qiyu Gongzi, a team of soldiers armed with halberds from outside the city, claiming to be from Jizhou, are here to defect to you!"

When Liu He heard this, he was overjoyed. "Well, this Zhang He is quite neat, and he sent people to me before the training group officially started!"

Liu He then changed his itinerary and led people to the gate of the city to personally welcome the halberd into the city.

It stands to reason that with Liu He's current status, he doesn't have to go to greet a group of big-headed soldiers in person, as long as he sends someone around him to represent him, but in order to improve the status of this group of halberds in Macheng, he specially went to greet him.

After all, these soldiers came from Jizhou, and after coming to Youzhou, they are not familiar with the place, if Liu He does not support them, how will they do training in the future?

Liu Hui stood near the city gate, carefully observing the people entering and leaving the city, and found that whether they were going to enter the city or preparing to leave the city, everyone seemed to be in a hurry, for fear of delaying time. Liu Hui took a closer look at the subtle expressions on the faces of these people, and found that although everyone was anxious, they did not have nervous and panicked expressions, but they were all happy and full of anticipation.

A man dressed as a vendor was muttering to the driver of the car: "You must be careful, this car is loaded with eggs I collected from nearby villages, and baskets of them must be sent to the training regiment. ”

The coachman asked a little puzzled: "What is this training regiment?" In the past few days, I have seen several ox carts delivering meat and vegetables to the city, as well as all kinds of wood, ropes, and cloths, and I have not seen any reinforcements from the garrison in the city. ”

The vendor shook his head, not knowing. "Where do I know this, anyway, the logistics officer of the training regiment came to my shop and made this big deal with me, so that I can deliver eggs to the camp every five days in the future, so I will rent your ox cart for a long time, and I will have to work harder in the future!"

Liu Hui listened with great interest to the conversation between the two masters and employees who were eager to enter the city, and was also curious about the "training group" that repeatedly popped up in their mouths.

When Liu He came to the gate of the city surrounded by the guards, the people who came in and out consciously gave way to a passage, and there was no scene where the guards drove the people away with leather whips.

"Everyone, let it go! The eldest prince is going out of the city! Someone in the crowd shouted spontaneously.

When the vendor who was waiting in line to deliver the eggs heard this, he hurriedly said to the driver who was driving the cart: "Hurry up and lean the ox cart to the side, don't get in the way of the eldest prince!" ”

Liu Hui, who had been silent, followed the sound and looked forward, and saw a young man in high spirits sitting on the back of a strong black horse, clenching his fists to thank the people around him who took the initiative to give way.

Under the guidance of Sima of the East Gate Army, Liu He soon came to the place where the Euphorbia was standing and waiting.

Liu He was not short-sighted, and as soon as he left the city, he saw dozens of long halberds not far away, as well as the middle-aged scribe standing at the front under the long halberd.

Liu He thought to himself: How did this person get together with the Euphorbia? I haven't heard of any scribes under Zhang He!

With doubts in his heart, Liu He turned over and dismounted, and walked towards the middle-aged scribe under the protection of the guards.

"I wonder what this gentleman is called?" Liu He asked first.

The team leader who served as the leader of the northward expedition quickly replied: "Son Qiyu, this is Mr. Liu Zihui, who once served as Jizhou Zhizhong, and this time he came to Macheng to play for Gongzi." ”

"Hey, why is it a family surnamed Liu?" Liu He muttered to himself in his heart, but there was a surprised expression on his face.

"Grass people Liu Hui, I've seen my son!" Without waiting for Liu He to salute, Liu Hui took the initiative to salute first.

"Mr. Zihui can't do this!" Liu He hurriedly helped up Liu Hui, who was bowing, and then solemnly returned the salute, and said: "Mr. Zihui can come to Macheng, it is really an honor for the kid!" ”

After some politeness, Liu He led Liu Hui and fifty halberd warriors into the city.

Because he couldn't figure out where Liu Hui came from, Liu He found an excuse on the road, saying that he wanted to settle fifty soldiers from Jizhou, and first asked Liu Hui to go to his mansion with two guards, while Liu He took the halberd soldiers to the halberd camp.

The training regiment was about to start, and Macheng, as the station of the archery battalion and the halberd battalion, had all the preparations in place, and after the halberd soldiers who came to Macheng as the head of the training team entered the camp, they were properly settled down by Liu He.

Liu He asked the team leader at the city gate to call and carefully inquire about Liu Hui.

This team leader has been in the army in Jizhou for many years, and he is familiar with the affairs of Liu Hui and Han Fu, so he reported to Liu He in 1510.

After Liu He listened, his face showed hesitation, and for a while, he didn't know whether he should keep Liu Hui, a talent sent to the door, in Macheng.

If Liu He left Liu Hui behind, what would Han Fu think if this matter reached Han Fu's ears? The person I Han Fu discarded, but you Liu He treated me like a guest, isn't this a clear slap in the face?

Although Han Fu is cowardly and mediocre, he can't fall now, let alone conflict with Youzhou. Liu He also counted on letting Han Fu continue to contain Gongsun Zan and Yuan Shao in Jizhou, and win more strategic space and development time for himself!

If Liu He didn't take in Liu Hui, it wouldn't be nice to hear about it. With Liu Hui's reputation in Jizhou, such a talented person came to serve, and you Liu He didn't take him in, what else did you talk about seeking talent, respecting and loving talents?

For a while, Liu He was worried about whether to take in a talent for the first time.
