Otaku Engineer in Great Tang Dynasty

　　 In the hall, the situation suddenly changed.

　　 Li Zexuan, who was originally charged with two crimes, managed to resolve the crisis with a few words and turn himself into peace.

　　 This quick wit, this calmness, is really not like the first time I went to the pilgrimage to meet the Maotou boy.

　　 Cheng Yaojin, Qin Shubao, Niu Jinda and others looked at Li Zexuan with faint appreciation.

　　 Li Er thought it should be all right now, so he asked, "Does Zhu Qing have something to play?"

　　Who knows that someone really stood up at this time, it was Yan Lide.

Yan Lide's mood today is really ups and downs. He originally planned to ask for Li Zexuan's credit at the beginning of the court. How did he know that the impeachment of Li Zexuan happened one after another. He was a little puzzled. Li Zexuan is just a piece of cloth. What about the big guy in the court? Will there be time to impeach him?

　　 In the middle, he also had the thought of wanting to help. However, he has been obsessed with crafts and architecture all his life, and he is really not good at intrigue.

　　 To his surprise, Li Zexuan turned the crisis around on his own.

　　 Seeing that the situation was settled at this time, he quickly stepped forward and said: "Your Majesty, the old minister has something to tell."

　　 Li Er asked casually and then he was about to leave the dynasty. Today’s morning dynasty took a long time to open. I didn’t expect that Yan Lide would have something to do.

　　 Li Erqiang cheered up and asked: "What's the matter with Yan Aiqing?"

　　 "Return to your Majesty, the old minister wants to take credit for Li Zexuan!"

　　 "Oh?" Li Er came to the spirit. Today's morning session was really interesting. Li Zexuan is about to become the protagonist of this morning session with a cloth body.

　　 "Yan Aiqing, what credit does Li Zexuan have?" Li Er asked with interest.

　　 The other ministers also looked at the boy curiously.

"His Majesty, Li Zexuan a few days ago, he invented a part called a roller bearing, which can be installed in the rotating joints of all machines and can greatly reduce resistance. At present, it has been developed for monitoring and used in On the carriage.

　　 Compared with the carriage with traditional bearings, this new carriage is more flexible and has less forward resistance. After being tested by the supervising craftsman, under the same animal power, the new horse-drawn carriage can carry more than 80% of the extra cargo, which is extremely beneficial for the transportation of grain and grass when the two armies are at war. "

　　 "Oh, what happened?"

　　 Li Er stood up excitedly. He also fought for more than ten years, and he knew the importance of the efficiency of food transportation.

　　 "Returning to the emperor, this is indeed the case. When Erchen first co-founded Qiquge with Li Zexuan, he had already proposed the concept of roller bearings, and he was also endorsed by Yan Shaoning, the son of Yan Shangshu."

　　 Li Chengqian jumped out to support his good friend.

　　 Li Er glanced at Li Chengqian, then looked at Li Zexuan, and laughed: "Okay, okay, okay, Li Zexuan, I didn't expect you to be very talented at a young age, you deserve a reward!"

　　 Yan Lide continued:

　　 "Your Majesty, the old minister hasn't finished! Li Zexuan invented a new type of plough three days ago, named Quyuanli, and built a batch yesterday. This plough is not only more labor-saving, but also more flexible.

　　 After the trial yesterday, it has been proved that the Quyuan Plow is at least three times faster than the long straight plow we used before. The veteran believed that the court should vigorously promote the Quyuan Plow to solve the problem of the current shortage of cattle in the Tang Dynasty. "

　　 His Majesty Li Er, who has always been calm and comfortable, is not calm at the moment, he dare not say:

　　 "Yan Aiqing, there really is such a plow in this world?"

　　 Yan Lide bowed and said: "Your Majesty, the veteran is willing to guarantee his life, this is absolutely true."

Cheng Yaojin also stepped forward and said: "Your Majesty, my old Cheng can also guarantee that my ugly cow also went to Zhuangzi with Li Zexuan yesterday. He also saw with his own eyes that this Quyuan Plow is indeed faster and more effortless, even with a little effort. Older men can move."

　　 "hiss~"

　　As soon as Cheng Yaojin's voice fell, the ministers above the court immediately boiled, all with air-conditioned voices. Yan Lide had said so much before, and many of them did not have an intuitive understanding of Quyuanli. At this time, Cheng Yaojin said that people could actually pull the plow to plow the land, and they were shocked instantly.

　　 people pull pears to plow the land, in their opinion, it is simply a fantasy. Is this song plough really that magical?

　　 Li Er also felt that Cheng Yaojin was a bit exaggerated. He looked at Li Zexuan and asked:

　　 "Li Zexuan, is this song plow really so magical?"

　　 Just now when Yan Lide came out and said that he was going to ask for credit for himself, Li Zexuan was a little dazed. Today, when he came to this Tai Chi Palace, it was like riding a roller coaster with ups and downs. It was really exciting.

　　 It took a long time for Li Zexuan to react. At this time, listening to Li Er's question, he quickly replied:

"His Majesty, this is indeed the case. Yesterday, hundreds of households in Hanjiazhuang witnessed the speed of arable land with Quyuan Plow. The kid did not dare to conceal it. In addition, Qiquge Workshop has already started to produce Quyuan Plow with all its strength. There will be more and more plow farmers, and more people will know the advantages of Quyuan Plow."

"it is good!"

　　 Li Er couldn't help but yelled hello. These days, he has been worrying about the spring plowing problem of Zhuangzi in the counties around Chang'an~www.ltnovel.com~ He originally planned to farm cattle from the north, but he was robbed by bandits on the road.

　　 When I received the news before, Li Erqi's nose was crooked, but he is currently unable to take care of the bandits, because the spring plowing period is about to pass, and he has to hurry up and adjust the cattle from other places. Li Er is really frustrated these days.

　　 Now that Li Zexuan invented a more efficient Quyuan Plow, all these problems have been solved, and this thing can be regarded as an artifact that benefits the country and the people. It is too important. Li Er, who had been frustrated for several days, could finally breathe.

　　 "Can this tune plough be manufactured on a large scale?"

　　 Li Er hasn't gotten too excited yet, he knows that time is running out, and the farmer is anxious for spring plowing.

　　Li Zexuan replied:

"His Majesty, the structure of the Quyuan Plow is not complicated. The kid’s workshop can produce one or two hundred in a day. But now the farmers are eager for spring ploughing, and the personal abilities of the small people are limited, and they cannot satisfy all the farmers in a short time. Need. The kid is willing to dedicate the drawing of the Quyuan Plow to the court, and the court will make it with all its strength, so that all farmers will not miss spring ploughing as soon as possible."

　　 One is that this Quyuan Plow does not make much money, and the other is that Li Zexuan does not have the ability to produce a large number of Quyuan Plows at once, which will delay many farmers' spring ploughing. In this view, it is better to hand it over to the court.

　　 Li Er laughed and said: "Your kid is quite righteous, not bad, Yan Aiqing, this matter will be handed over to your Ministry of Industry. During this time, you have all the craftsmen working overtime to make a batch of Quyuan ploughs."

　　 Yan Lide hurriedly said, "Here, your majesty, the old minister will personally supervise it."

　　 "Well, that's the best, it's just that I have to work hard to love Qing!" Li Er nodded and smiled.
