Otaku Engineer in Great Tang Dynasty Chapter 66: Spring ploughing is difficult

　　Hanjiazhuang, farmland outside the village.

　　 Old Hu kept thanking the young master a lot, but his mouth was dumb, and he always said those few words. Li Zexuan was very embarrassed when he heard it. Han Li was interrupting him when he saw this. Have you waited here for so long, haven’t you waited for the cattle?"

　　 Old Hu Wenyan, shook his head dejectedly, and pointed to a middle-aged man who was cultivating the land not far in front and said: "Lizheng, you see, Lao Wang’s house hasn’t run out yet. There has been little rain this year, and this field is always difficult. It’s plowing, I’m so worried about this."

　　"Uncle Han, can't I go to the county to borrow more cattle?"

　　Li Zexuan listened to Lao Hu's complaint, and he was a little confused, so he asked.

　　 Han Li was shook his head embarrassedly: "Master, you don’t know that we have a lot of people in Zhuangzi, and the county has more oxen allocated than other Zhuangzi. At this time, all places are ploughing in spring. There must be no extras in the county. The oxen are given to us."

　　 Lao Hu also sighed heavily at this time: "Oh, Lizheng, at the current rate of plowing the land, I guess that many farmers in Zhuangzi might miss the spring plowing period. How can this be done?"

　　 Li Zexuan was also shocked when he heard this. He was also a child in the countryside in his previous life. He knew how serious the consequences of missing the spring plowing period were. By then, many families would be hungry. Not to mention that everyone missed the spring plowing, which would definitely affect their chicken raising Enthusiasm, this problem must be solved.

　　 He pondered for a while, looked at the old Hu next to him, and asked: "Uncle Hu, how much land can a cow cultivate in a day?"

　　 The old man scratched his head and thought for a while and said: "Master, this year it is difficult to plow the land. A cow can plow up to four acres a day. If you plow more, you are afraid that the cow will be exhausted. If this is in previous years, you can generally cultivate six or seven acres of land a day. Alas, I blame this year for too little rain."

　　 There are only four acres of land in a day, this speed is too slow, Li Zexuan frowned, looked at Han Lizheng, and asked: "Uncle Han, how many cattle are there in Zhuangzi?"

　　 "Master, this year Zhuangzi rented 20 cattle, which is much more than other Zhuangzi."

　　 Li Zexuan silently summed it up. At this speed, wouldn't it take more than a month to cultivate? This will not work. It's not that he never thought of spending money to buy cattle from other places, but in this era, cattle have always been nervous. He bought cattle from other places. What should the people do in that place? If you are like other protagonists, you can bring a system and exchange it for a farming tractor to ensure that you can plow dozens of acres a day.

　　 Alas, since there is no tractor, it is not easy to increase the number of cattle, so now it seems that we have to think of other ways to improve the current farming efficiency. This problem is very easy to solve. There are countless advanced mechanical models in his mind, and he can definitely find many plows that are better than the current ones.

　　"Uncle Han, let me see what plough the farmers use."

　　 Li Zexuan made an confession and walked to the old Wang who used to be a fool. Han Lizheng and Lao Hu also hurriedly followed.

　　Li Zexuan came to the ridge next to Pharaoh, his eyes began to focus on the plough used by Pharaoh. Lao Wang was plowing the land intently, and he didn't even notice that someone was watching him next to him.

　　 Li Zexuan had a high degree of myopia in his previous life. In this life, I don’t know if it was because of his magical powers, but his eyesight was very good, and he could see the structure of the plow clearly from a distance. He found that the structure of the plow was really strange. The plow shaft turned out to be straight, and the length reached about nine feet. It is probably difficult to turn around for such a long plow shaft.

　　 Li Zexuan quickly constructed the three-dimensional structure of the plow in front of him in his mind, and based on his previous engineering mechanics knowledge, analyzed the forces on each part of the plow, and found that the plow actually needs to be applied to plow the ground. The structure is obviously unreasonable due to the large pulling force.

　　 Li Zexuan frowned. He was thinking about which plow should be used instead of the current plow. Ploughs of different ages flashed in my mind one by one, and suddenly stopped on a plough that was not particularly different from the current plow.

　　 "It's you!"

　　" This should be called Quyuan Plow, and it shouldn’t appear yet. The structure of this Quyuan Plow should be improved from the structure of the current plough. Although the changes are not too big, every change is very important. Ah, compared to the plow used by Lao Wang, this curved plow is obviously more labor-saving. It is easy to see it by drawing a force analysis diagram."

　　 At this time, Li Zexuan had not only the three-dimensional model of the Quyuan plough, but also its force analysis diagram. It was obvious that the Quyuan plough was more labor-saving, and it didn’t save a little bit. The most important thing is that this plow is not difficult to manufacture, and it is easy to manufacture in large quantities. When he goes back, he can find a craftsman to start manufacturing immediately, so that the farmers in Hanjiazhuang will not miss spring ploughing.

　　 In fact, the Tang Dynasty currently uses the long straight plow which is handed down from the Han Dynasty~IndoMTL.com~The Quyuan Plow that Li Zexuan had in mind only began to appear in the Jiangdong area in the late Tang Dynasty, so it is also called As Jiangdong plow. Compared with the long straight shaft plow, the curved shaft plow is indeed more flexible and labor-saving. When the soil is relatively moist, a young man with greater strength can pull it.

　　 "Uncle Han, you plow like this first, I will find a way for you these two days, and I will never let the farmers miss the spring plowing." Li Zexuan had a solution in his mind, so he turned around and said to Han Lizheng.

　　 Han Lizheng and Lao Hu Wenyan both looked surprised. Land is the life of the farmers. If you miss spring ploughing, the harvest will be greatly reduced. It is not uncommon for people to starve to death. Unexpectedly, the young master would help them find a way, which is really amazing.

　　"Thank you, Master, all of our Hanjiazhuang dealers will remember the great favor of the Master for life. I just don’t know what the Master plans to do? Should I go to Chang'an to buy farm cattle?" Han Li was bowing very seriously, but he was also very curious about Li Zexuan. What method would he use to help them? If he bought farm cattle for them, the price paid would be too expensive.

　　 Li Zexuan shook his head and smiled: "Of course not to buy farm cattle. I bought the farm cattle. What do the farmers in other places use? Uncle Han, I will bring you a more labor-saving in two days. Plowing, your arable land speed will increase by at least two times!"

　　Han Lizheng and Lao Hu Wenyan were both surprised. Is there such a plow in the world?

　　 Old Hu exaggeratedly widened his bull's eyes and exclaimed in disbelief: "Young...Master, you...but what you said is true? How come there is such a plow in this world?"

　　 Li Zexuan nodded with certainty, and said: "Uncle Hu, don't worry, seeing is believing, we will see you in two days!"
