After hearing Li Yu's disdainful tone, Li Er immediately looked unhappy on his face and said, "All merits will be rewarded, and any mistakes will be punished. Otherwise, how can people convince people? Otherwise, wouldn't the imperial system be messed up?"

Seeing that Li Er wanted to show off his Qin King's prestige again, Li Yu snorted coldly: "Does the chaos have something to do with me? Today I had a new discovery and planned to do you a big favor. Since the court has so many rules, use your system to solve it."

After saying that, Li Yu turned around and was about to leave. Does he care about the power of the King of Qin?

After hearing Li Yu's words, Li Xiuning saw him turn around and was about to leave, and hurriedly stepped forward to stop him: "Okay, my master! If you don't ask for me, you'll help me. I'm really afraid of your weird temper."

"Awesome! You are awesome! I really believe you. I dare to scold the court system. I think you are the best in the whole world." Li Er laughed out loud by Li Yu's behavior.

Li Yu rolled his eyes directly to Li Er and ignored him.

When Li Er met Li Yu who dared not take him seriously, he had no choice but to see Li Yu, not to mention that the third sister next to him was still eyeing him. If he dared to do anything to Li Yu, the third sister would not let him go immediately.

Seeing Li Yu's appearance, Li Xiuning understood that he didn't dare to be an official in front of him, so he hurriedly asked the important matter: "You just said that you found a problem, what problems did you find?"

Li Yu said lightly: "Why are there so many cattle on the grassland, but why are there so few cattle that can cultivate the land in the Central Plains?"

Li Xiuning turned Li Yu's beautiful eyes and said, "Who doesn't know that a cow has to be tamed since he was a child and can only go to the fields to work. Even a naughty boy of a young age knows this. Would you, Li Da Caizi, not know?"

After the explanation, Li Xiuning looked at Li Yu with confusion.

After waiting for a while, she seemed to have not understood what Li Yu looked like.

Li Xiuning carefully promoted the living habits of cattle to Li Yu. Since he was born, this calf from the Central Plains has been learning to pull carts, cultivate land and various abilities from old cows and humans. When the calf grew up, he naturally learned a lot of skills. The calf on the grassland has not experienced these skills training, so those cattle came to the Central Plains and were used to being wild on the grassland. It was not easy to domesticate them into cattle who obeyed and understood the words of cows. What's more, the people can't eat enough, so how could they raise a useless cow?

After hearing Li Xiuning's words, Li Yu understood the different habits of the cattle on the grassland and the cattle on the Central Plains. Instead, he smiled and asked: "Why don't you want to make a solution to quickly domesticate the cattle on the grassland so that the people can use it? No longer have to let someone pull the plow?"

Li Xiuning rolled his eyes to Li Yu again: "You can talk nonsense! A cow is a beast, how can it be quickly domesticated if you don't understand human language?"

Li Yu ignored Li Xiuning's words and asked, "Have you heard of this allusion that cows don't drink water and forcefully press their heads?"

Li Er dared not act like the King of Qin at this time, and Zou Zou browed and said, "But what does this have to do with domesticating the cattle on the grassland? Can you force it to cultivate the land if it doesn't cultivate the land?"

Li Yu also followed Zou Zou's eyebrows and said, "I think you are so stupid that you are so stupid, just forcing domestication. Since snakes are seven inches, cows still have them too. As long as you find the weakness of the cow, what do you want it to do, it will only do."

"You just want to do what?" After hearing this, Li Xiuning knew that he must have a way, otherwise he wouldn't have said so confidently. She was also full of expectations for Li Yu's way of quickly domesticating cattle. Agricultural production cannot be separated from cattle. As long as the cattle on the grassland can be quickly domesticated, the agriculture of the Tang Dynasty can develop rapidly immediately.

Li Yu did not keep it in hiding and told them directly how to do it: "It is to add an iron bar or hardwood bar to the bull's nose, so that the cows that come down from the grassland will be honest and obedient in the future."

After saying that, Li Yu explained in detail to them how to control cows in later generations, and the shape of tools to control cows.

After hearing this, Li Er immediately felt that this method was feasible. If it was really successful, it would save a lot of manpower for the Tang Dynasty and reclaim a lot of land.

Thinking of this, I ignored everyone and excitedly rode on my horse and left.

Li Yu watched Li Er ride away excitedly, and it seemed that he was planning to find a place to experiment.

Li Xiuning looked at Li Yu in surprise and asked, "Is Li Yu too cruel to Niu doing this?"

Li Yu said calmly: "How cruel is it? After these cattle that came down from the grassland learned to cultivate the land, who would be willing to kill them? In this way, their lifespan would be extended."

Li Xiuning thought about it and it seemed that that was the case.

After a while, Zhang Ergou brought the cow condom and put the cow's mouth up, so that it was not allowed to be held in the way. Judging from the effect of the cow condom, the two scalpers were disobedient in the early days and went to find green grass to eat, but the cow condom was blocked and they could not eat the grass in the field. After repeated many times, the two scalpers stopped looking for green grass to eat, and honestly plowed the field.

"I didn't expect that a ox condom woven by bamboo would have such great effect." Li Xiuning saw two scalpers not holding anyone, and was honestly plowing the land, with a pair of apricot eyes wide open.

After Li Xiuning was surprised, her apricot eyes flashed, and she looked straight at Li Yu. She never expected that Li Yu, a scholar, had never been to the ground, could come up with so many solutions. It was really strange. It seemed that there was no problem that could stump him.

"Of course, otherwise why would I invent this thing? In addition, it will be better to use it with the cow with the nose that has passed through it." Li Yu's body was shocked.

Li Yu left after explaining. Seeing that Li Xiuning was full of suspicion of himself again, he was afraid that the woman would ask questions again, and that his purpose was achieved today, and it would be wise to leave at this time.

"Hey! What are you doing in a hurry to go home?" Li Xiuning shouted at Li Yu who left after saying that.

"I saw that there were a lot of red bumps on your arm by autumn mosquitoes. I went to Chang'an to buy some medicine and make it into flower dew for you to use, so that you will not bite the mosquitoes in the future."

After hearing Li Yu's words, Li Xiuning felt warm in her heart. She felt that this man really cares about people. She was bitten by mosquitoes on her body and wanted to solve it for herself.

Li Xiuning looked at Li Yu's back happily and shouted again: "Then I'll go get it in the afternoon."

"Yeah!" Li Yu, who was walking, just said "Yeah!" without looking back.

If Li Xiuning knew that Li Yu saw the bumps left by mosquito bites on Li Fei'er and Li Chun, he remembered making flower dew. If she thought that Li Yu was not the flower dew made for her, she would not know if the arrogant and savage Li Xiuning would pounce on him and strangle him to death after knowing it.

...

Li Er came to the military camp to find his subordinates and asked them to find a few cows transported from the grassland. He told them in detail how to wear the nose of the cow and control the cows.

After a while, my subordinates brought in a few cows from the grassland.

I saw a yellow cow being knocked down to the ground by several powerful soldiers, tied up his limbs, and found a veterinarian. The veterinarian held an iron bar as thick as chopsticks in his hand. One was sharply polished, aimed at the cartilage between the two nostrils of the cow and penetrated it. I heard the yellow cow screaming "Moo!" "Moo!" "Moo!"...

The soldier didn't care about the scalpers that were worn on the nose. Then, according to Li Er's request, he made an iron button to fix a hardwood strip on the cow's nose, and then let go of the screaming scalpers.

The scalper who had just returned to freedom stood up, and his former wildness disappeared. Instead, he looked at the soldiers pitifully, hoping that these cruel humans could take out the wooden strips in their noses.

After the cow's nose was fixed with hardwood strips, he used a thin cowhide rope to buckle the cow's nose ring. The veterinarian held it in his hand and gently patted it on the cow's butt. The cow walked forward honestly and turned it around a few times in the military camp.

The scalper whose nose was worn was very obedient and obedient. He let it go and let it stop, and it stops.

After reading it, Li Er was ecstatic and asked the veterinarian and the soldiers to wear a few more cows to test it to prevent mistakes.

After experimenting with the noses of several cows, I found that the cows with the noses of the cows were very honest and obedient.

After seeing the conditions of these cows, Li Er said happily: "As long as you recover the injuries in the cow's nose and then tame it for a while, you should be able to go to the fields to work."

Unexpectedly, Li Yu's method was really effective, which made Li Er even more eager to recruit Li Yu.

"Your Highness! This is a good method! Just wearing a hardwood strip into the cow's nose can make a cow that has never been domesticated so gentle. It will no longer take a few years to tame a cow. In this way, a large number of cows on the grassland can be converted into oxen used by the people. Moreover, each cow can save manpower, and the area of ​​farming can be greatly increased in the future, so that the problem of food and clothing for the people can be solved quickly." A fat Confucian scholar analyzed.

Li Er was silent for a moment before asking, "Wuji! You said this method is so easy, why hasn't anyone thought of it for thousands of years?"

"And the cow condom I just mentioned, Xinpie, why can a scholar who has never planted the land come up with so many good solutions?"

The fat Confucian scholar who was talking to Li Er was Changsun Wuji, a famous person in history.

Changsun Wuji, who is good at observing his face, saw that Li Er was so concerned about recruiting Li Yu, and quickly said, "I know what you mean by Your Highness. I will send people to pay attention to his every move and find a way to recruit him to your Highness's disciple in the future."
