"Gongyou's bridge is about to be repaired, and we are going to hold a small completion ceremony, but are you sure you want to collect money?" Lu Su asked hesitantly. "Isn't this already agreed upon? You have to pay for taking a boat across. If I don't charge for building such a bridge, how can I recover the cost?" Chen Xi said unceremoniously. "Then it's up to you. You'll be able to receive the news in a while, but what exactly is it that you asked Zheng Wengong to make? He has already mobilized more than a dozen master craftsmen, and he still wants to extract people. We just don't have enough manpower." Seeing Chen Xi's determination, Lu Su did not argue with Chen Xi, but told the story and started talking about the next thing. "Wen Ru should know that when we were at Wen He's place, we saw a small waterwheel that could attract the essence of heaven and earth with its spiritual power and run automatically, so I asked Wen Gong to design a machine based on this. After all, Wen Gong is very good at this kind of thing." Chen Xi smiled and explained. In fact, Chen Xi just told Zheng Hun the principle. Obviously, compared to people like Jia Xu and Li You, they may not understand the meaning. However, after Zheng Hun took over, he immediately understood that this thing is just like the legend. Among them, Luban¡¯s wooden figures are like wooden kites and have mechanical power. Especially when Chen Xi explained steam power to him, Zheng Hun really understood the meaning of this thing better than Li You, Jia Xu and others, but he didn't know how far he had achieved it now. Just when Li You was about to explain this matter, Zheng Hun came to the Government Affairs Office with a thin but very capable guy, but Zheng Hun obviously looked unhappy. Chen Xi has never met the person Zheng Hun brought with him. Although Chen Xi doesn't remember people very much, he still has an impression of the main people. "Hey, Mr. Wen, we were talking about you just now. How did you do with the work that I arranged for you before I left?" Chen Xi didn't mind the new person brought by the other party and asked directly. "It's completed." Zheng Hun said with a wry smile, "I took more than thirty master craftsmen and worked for a year. If Deheng hadn't been more talented in mechanical modification, I'm afraid we wouldn't be able to make it now." Zheng Hun said with a wry smile. Although Hun looked unhappy and looked even more unhappy at the man next to him, he did not criticize him. "Fufeng Ma Jun, Ma Deheng has met Chen Hou, Lu Governor, and Li Shangshu." Ma Jun leaned forward and said, he did not feel that his status as a craftsman was low. "Oh, I remembered. I remember you were an official with Cao Sikong. Why did you resume your main position?" Chen Xi was slightly startled. Back then, he had asked someone to recruit Ma Jun, but at that time, Ma Jun was already there. Cao Cao is messing around. "We are both from the Han Dynasty, how can we be like Cao Gong and Liu Gong?" Ma Jun replied plainly. It was obvious that he was not an unlucky boy who had never gone to school. At least what he said was very reasonable. In fact, it was an accident that Ma Jun came to Liu Bei's side. Ma Jun was a doctor at Cao Cao's side at first. Later, Liu Bei's craftsmen continued to develop new things and their status rose. Cao Cao's side also followed suit, and Ma Jun also So he went to work as a craftsman under the Shaofu. First of all, you need to admit that Ma Jun is very strong in machinery. Although everyone is a master craftsman, in fact, there are also biases. Ma Jun prefers the early Mohist type of mechanical research and production, so he did very well when he was a young man. Because he can indeed figure out a lot of things. What Zheng Hun is working on here is actually a hybrid machine that combines the essence of heaven and earth plus steam power. In short, the one who is best at mechanical power among Liu Bei's master craftsmen is Huang Yueying. But this thing cannot be made by just a few people. The mechanical parts are highly matched and made from scratch. Every bit seems simple, but if it is done, it actually transcends the industrial level. Humans are considered miraculous animals. Anything that can be made by precision machine tools can also be made by someone's hands. Since the accuracy level is so high, Zheng Hun can only find someone. There is always a master craftsman who can make it with micron-level precision by hand. grade. You must know that great craftsmen also have dreams. When people live well, they will always have some thoughts of self-realization. Compared with Li You and Jia Xu, great craftsmen can better understand the meaning of such a piece of machinery, so Zheng Hun La Sheep is not difficult. The problem is that a creature like a master craftsman will be equivalent to a basic fitter in future generations. A lathe can become an engineer based on his craftsmanship. There are very few such people in later generations. Naturally, even if Zheng Hun wanted to recruit sheep in this era, he would not be able to find as many people as he wanted under Liu Bei. In addition, many great craftsmen went to hang out with Sun Qian. Zheng Hun touched around here and almost stopped the water conservancy construction, and he only touched a dozen. In this case, you can only touch others. Zheng Hun said that he is a craftsman. There is a family behind him called the Zheng family. In later generations, the five surnames of Qiwang Xingyang are the Zheng family, so touching Luoyang and Chang'an is considered by the Zheng family No difficulty. Therefore, Ma Jun inexplicably found that the number of master craftsmen under him was decreasing day by day.The number of twenty-two was reduced to a dozen, and finally to a few, and finally Ma Jun was also taken away by Zheng Hun. After all, people have to have dreams. As the current pinnacle figure in mechanics, Ma Jun naturally also has dreams. He chased his master craftsman to Yecheng. At first, he was ready to do it, but later he discovered what Zheng Hun was working on. , it¡¯s very classy, ??so while I was unhappy, I followed suit. Although it happened at the beginning, because I didn¡¯t understand the process, a crowbar flew and hit me, and my ribs were almost broken. Of course, there are cases where the air tightness is acceptable at first, but later because the pressure is too high, high-temperature steam bursts out, almost cooking people. There are also a series of things such as unqualified parts accuracy, unqualified gear strength, unqualified mechanical transmission, unqualified sealing, etc. All in all, it is extremely dangerous. However, the danger is not important to this group of people. What is important is that they can clearly feel the mystery contained in it. They may be as famous as Lu Ban through the ages because of this. Just like the elders, Chen Que and the others, they did not take part in the master craftsman assessment. They must complete the construction of the Yellow River Bridge before leaving. The reason is that their names will be with this bridge, while others are engraved on the bridge. On the stone tablet next to it, they are engraved on the bridge foundation. So even if a bloody hole was made by the flying parts, they would endure the pain and continue to work, and the men would be with this thing. In short, after working on it for about a year, this group of people finally produced a qualified heaven and earth essence-steam hybrid machine. As for making another one, now that they have a complete set of drawings, it is not that simple to make another one. It took more than thirty master craftsmen, plus two master-level figures to make something for a year, and it was so hard. The feel of the hand increases the accuracy to the extreme level.
