In the court, the situation changed abruptly.

Li Zexuan, who was originally charged with two crimes, actually resolved the crisis with just a few words, and turned himself from danger to safety.

This wit, this calmness, really doesn't look like the first time to enter the Hajj to meet the hairy boy.

Cheng Yanjin, Qin Shubao, Niu Jinda and others looked at Li Zexuan with a faint appreciation in their eyes.

Li Er felt that it should be okay now, so he asked, "Do you have anything to do?" ”

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

Yan Lide's mood today is really full of twists and turns, he originally planned to ask for credit for Li Zexuan at the beginning of the early dynasty, how did he know that Li Zexuan's impeachment was one after another, he couldn't figure it out, Li Zexuan was just a cloth cloth, how could the bigwigs in the court have the time to impeach him?

In the middle, he also wanted to help, but he has been obsessed with craftsmanship 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 had been settled at this time, he hurriedly stepped forward and said, "Your Majesty, the old minister has something to do. ”

Li Er originally asked casually and then prepared to disperse, but today's morning court opening time is really a bit long, but I didn't expect Yan Lide to have something to do.

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

"Back to Your Majesty, the old minister wants to ask for credit for Li Zexuan!"

"Oh?" Li Er came to the spirit, today's early dynasty is really interesting, Li Zexuan is about to become the protagonist of this early dynasty with a cloth body.

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

The other ministers also looked at the young man with curious expressions.

"Back to Your Majesty, Li Zexuan invented a part some time ago, called a roller bearing, which can be installed in the rotating connection parts of all machinery, which can greatly reduce resistance. At present, the prison has been developed and used in horse-drawn carriages.

Compared to carriages fitted with conventional bearings, this new carriage is more agile and has less forward resistance. After being tested by the craftsmen who would be in charge, the new wagon could carry more than eighty percent of the goods under the same animal power, which was extremely advantageous for transporting grain and grass in the event of a war between the two armies. ”

"Oh, that's it?"

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

"Back to my father, there is indeed such a thing. When Erchen first co-founded Qiquge with Li Zexuan, he had already proposed the concept of roller bearings, and he was also approved by Yan Shaoning, the son of Yan Shangshu. ”

Li Chengqian jumped out at this time to support his good friend.

Li Er glanced at Li Chengqian, then looked at Li Zexuan again, and said with a smile: "Okay, good, good, okay, Li Zexuan, I didn't expect you to be so young, but you are talented, you should be rewarded!" ”

Yan Lide continued:

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

After yesterday's trial, it has been proved that the curved plough is at least three times faster than the long straight plough we used before. Lao Chen believes that the imperial court should vigorously promote the Quyuan plough to solve the problem of insufficient ploughing cattle in the Tang Dynasty. ”

His Majesty Li Er, who has always been calm and comfortable, is also a little uncalm at the moment, and he can't believe it:

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

Yan Lide bowed and said, "Your Majesty, the old minister is willing to guarantee his life, this matter is absolutely true. ”

Cheng Yanjin also stepped forward and said: "Your Majesty, I can also guarantee that my ugly cow also went to Zhuangzi with Li Zexuan yesterday, and he also saw with his own eyes that this Quyuan plow is indeed faster and more labor-saving, and even a man with a little more strength can pull it." ”

"Hiss~"

As soon as Cheng Yanjin's words fell, the ministers above the court immediately boiled, and they were all gasping for air. Yan Lide said so much before, and many of them still don't have an intuitive understanding of Quyuan plow. At this time, Cheng Yanjin said that people could pull the plough to plough the land, and they were shocked instantly.

People pull pears to plough the land, in their opinion, it is simply called a fantasy, is this zigyuan plough really so magical?

Li Er also felt that what Cheng Yanjin said was a bit exaggerated, he looked at Li Zexuan and asked:

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

When Yan Lide came out just now to ask for credit for himself, Li Zexuan was a little confused, today he came to this Taiji Palace, it was really like riding a roller coaster, ups and downs, really exciting.

It took Li Zexuan a long time to react, and then he listened to Li Er's question, and hurriedly replied:

"Back to Your Majesty, this is indeed the case, yesterday hundreds of households in Hanjiazhuang witnessed the speed of cultivating the land of Quyuan Plough, and the kid did not dare to hide it. And the Wonder Pavilion Workshop has begun to produce Quyuan plough with full force, and there will be more and more farmers who can use Quyuan plow, and more people will know the superiority of Quyuan plough at that time. ”

"Good!"

Li Er couldn't help but shout hello, these days he has been worried about the spring ploughing problem of Zhuangzi in the counties around Chang'an, and he originally planned to transfer ploughing cattle from the north, but who knew that he was robbed by mountain bandits on the road.

When he received the news before, Li Erqi's nose was crooked, but he couldn't spare his hands to clean up the bandits at present, because seeing that the spring plowing period was about to pass, he had to hurry up and transfer cattle from other places. In the past few days, Li Er has been really aggrieved.

Now that Li Zexuan has invented a more efficient Quyuan plow, then all these problems have been solved, and this thing can be regarded as an artifact for the benefit of the country and the people, it is too important. Li Er, who had been aggrieved for several days, could finally breathe a sigh of relief.

"Can this curved plough be made on a large scale?"

Li Er hadn't been overly excited, he knew that time was pressing, and the farmer was in a hurry to spring plough.

Li Zexuan replied:

"Back to Your Majesty, the structure of the Quyuan plough is not complicated, and the boy's workshop can make one or two hundred in a day. But now the farmers are in a hurry for spring ploughing, and the small people's personal ability is limited, and they cannot meet the needs of all the farmers in a short time. The boy is willing to dedicate the drawings of the Quyuan plough to the imperial court, and the imperial court will make every effort to make it, so that all the farmers will not miss the spring ploughing as soon as possible. ”

The first is that this quyuan plough can't make any money, and the second is that Li Zexuan really doesn't have the ability to produce a large number of quyuan ploughs at once, which will delay the spring ploughing of many villagers, so it seems that it is better to hand it over to the imperial court.

Li Er laughed and said: "You kid is quite aware of righteousness, not bad, Yan Aiqing, this matter will be handed over to your Ministry of Industry, during this time, you ordered all craftsmen to work overtime to make a batch of Quyuan plows." ”

Yan Lide hurriedly arched his hand and said, "Well, Your Majesty, the old minister will definitely personally supervise it." ”

"Well, that's the best, it's just that you have to work hard for Aiqing!" Li Er nodded and said with a smile.
