After talking about 'printing', it was time to get to the main topic of today, Li Mu welcomed Li Shimin and the other three into his studio and showed them the finished Quyuan plow.

Entering the house, all three of them showed a slight look of surprise. Li Mu's studio, except for Li Chongyi, no one has ever come in on weekdays, and Li Ji is here for the first time. Seeing this room full of tools and raw materials, the three of them didn't say anything, but they also secretly admired it in their hearts, Li Mu was able to make so many things, it seemed that it was not for nothing, secretly he did study it.

The Quyuan plough was placed on the workbench, and Li Mu moved it down and put it on the ground for Li Shimin to demonstrate.

"Your Majesty, please see, compared with the original plough, the most obvious difference between this new type of plough is the plough, the original plough is straight, after the trial of the minister, improved into a curved curved wheel, this improvement can greatly save animal power."

"The second minister added three parts, the plough weight, the plow arrow, and the plow plate, if the plow is promoted, the plow arrow can be made downward, and the ploughshare will be deep into the soil. If the plough is raised, the plough arrow is upward, and the ploughshare is shallow when it enters the soil. The function of the plough disc is to allow the plow body to swing and enhance maneuverability. ”

"The part next to it is called the plough wall, which not only breaks the soil, but also pushes the ploughed soil to one side, reducing the resistance of the plough forward."

"The point is this ploughshare, this ploughshare is a double-layer ploughshare, the small ploughshare in the front section can be convenient for breaking the soil, and the large ploughshare in the back can further expand the broken soil, and the purpose of this is also to save labor. He experimented with this double-sided ploughshare in an open field, and an adult man was able to pull it. In this way, farmers who do not have livestock can also use this new type of plough, which greatly improves the efficiency of farming. ”

Although Li Shimin didn't understand the principle very well, he understood what Li Mu said. This new type of plough can be pulled not only by livestock, but also by people. This is great, you must know that there are not many cultivated cattle in Datang now, and cultivated cattle are not something that can be multiplied in large quantities in a year and a half, if people can replace cultivated cattle, then wouldn't it solve a big problem?

Li Shimin confirmed and asked: "Can people really pull this new type of plow?" ”

"The minister is sure that he can, the minister has tried it himself."

"Take me to find an open space, I will try it myself."

The eldest grandson Wuji hurriedly said: "Your Majesty, you are the Son of Heaven, how can you do such a lowly thing." ”

"I do things for the people, why am I low?" Li Shimin called Li Mu together, the two of them carried the plough out, and there was a place to plant flowers in the front yard, Li Mu put the plough on the ground, took a rope and looked at Li Shimin, and said, "Your Majesty, do you really want to test it yourself?" ”

"Of course, am I joking with you?"

Li Jidao: "Your Majesty, it's still a minister to replace you......"

"Hugh wants to talk nonsense, come!" Li Shimin motioned for Li Mu to get started, and Li Mu had no choice but to take the order and tie Li Shimin with a rope instead of a yoke. The eldest grandson Wuji frowned as he watched from the side, in his opinion, it was too unreasonable for the dignified son of heaven to be compared to a ploughing ox.

"Your Majesty, you can pull." Li Mu held the plow and said to Li Shimin.

Li Shimin heard Li Mu's signal, and learned to plough the ox and move forward, and it was really able to pull. Although the resistance can be clearly felt, it is indeed not difficult for adult men to complete.

Li Shimin pulled forward about ten meters, looked back at the reclaimed ditch, was very satisfied, and said: "Li Mu, as you said, it is very labor-saving and very flexible. From this point of view, not to mention twice, even if it is three times, it is possible, and you are really going to get rich this time. ”

Li Mu helped Li Shimin untie the rope and said, "Your Majesty, the minister has no intention of making money from this. ”

"Oh?" Li Shimin was puzzled: "You don't plan to use printing to make money, I can understand." You don't plan to make money with this new type of plough, don't you love money?

The minds of the people of the Tang Dynasty have not been brainwashed by Cheng Zhu Lixue, and even the emperor does not feel that everything in the world is his own. There is great respect for the invention of the individual, whether it is the monarch or the court, or the social environment. Secret methods, secret recipes, etc. are private, and it is illegal for others to steal them. Therefore, whether it is printing or this new type of plough, Li Shimin admits that it is Li Mu's private property, and he never thought of asking him to selflessly dedicate it.

"Ministers love money, but ministers don't love money." Li Muxi was fine, and said with righteous words on his face: "Without money, the minister cannot give his family a good life, so the minister loves money." But the minister didn't want to do anything for money, for the benefit of the country and the people, and the minister thought that if he used this to seek money, it would be despicable. It is contrary to the principle of the minister's life, and it is also contrary to the minister's attitude towards money. ”

"Your Majesty, please recall that these things invented by the ministers, so far, wine is used for profit, because wine is not necessary, and the people's lives have no effect if they do not drink alcohol. People who like to drink and can afford to drink are not ordinary people. And the minister earned money, but he didn't spend it himself, and the minister took it out to build a craftsman's workshop, and did not ask the court for money. Other things such as horseshoes, printing, and new ploughs are all useful things for the country, and the minister is not unaware of its benefits, but the minister only wants to dedicate it to His Majesty, strengthen my Tang Dynasty, and do not want to use it to make money. ”

Li Mu's words were sincere, and the facts were in front of him, and Li Shimin was not allowed to believe it. Li Shimin was moved, took Li Mu's hand, and said, "Aiqing is young, and I am very relieved to have such thoughts. These few things you have offered are all meritorious to the society, and the credit is not small, and I know it in my heart. You don't want money, I can only reward you with your official position, but you are already in the county at a young age, and it is really ...... to be rewarded again."

"Your Majesty, the minister doesn't want an official title, the minister thinks that the current life is very good, there is nothing missing, and there is no need for rewards."

Who doesn't like such a courtier? Li Shimin was very happy, the more Li Mu said this, the more he felt that he should express it, thought for a while, and said: "If you have merit, you will not be rewarded, and you will not be a wise man." You give me three things, and I give you three rewards. The horseshoe is good for the army, and I will enter you as a protector, and give you a team of forbidden troops as a guard. Printing is conducive to culture and education, and I have appointed you to be Dr. Guozi, and you can not take up the post, just to commend your contributions. As for this new type of plough...... I really don't know how to reward you, so I named this plow after you, so that everyone in the world will accept your kindness, how about it? ”

Li Mu hurriedly said: "The minister doesn't dare to accept so many rewards, if Your Majesty has to reward them, the minister will accept the first one." As for Dr. Guozi, the minister still doesn't want it, and he really doesn't dare to mislead people's children. In addition, the new type of plough, the minister thought that it was best to name it with His Majesty's year name, and only His Majesty could deserve the gratitude of the people of the world. ”

Li Shimin was a little moved, but he was embarrassed to touch Li Mu's light, so he pretended to be reserved and said: "This is not good." ”

Li Ji observed his words and quickly persuaded: "Your Majesty, don't reward too much, Li Mu is still young, and there will be opportunities to reward in the future, if you reward too much at one time, it will cause others to be jealous and hateful, and it is not a good thing for him." ”

The eldest grandson Wuji also persuaded with a message, and Li Shimin responded and said: "Since Qing and others have all admonished him like this, then I will accept it, so let's do it, it will be called 'Zhenguan Plough'." ”

"Your Majesty Shengming!"
