In Shangfang Mansion, Liu Chang, surrounded by a group of craftsmen, was seriously disassembling and assembling a bunch of textile machine parts.

Liu Chang finally understood why the weaving machine he made was so easily damaged.

To put it simply, Liu Changtai pursues efficiency, and his steps are bigger, he is doing it according to the textile machine in his memory, but the textile machine in the future is not a mortise and tenon mechanism, it is a nail and a variety of adhesives, so that it can not be damaged at the maximum power, but now this structure...

Now that you understand the key, you can solve it by reducing the vibration or changing to another structure.

As for the matter of farm tools, then Liu Chang really has to learn from scratch, he searched in his memory over and over again, and he didn't find any knowledge about farming, but there was a tractor, but he couldn't do it!

Fortunately, Shang Fang is a perfect institution, because of Xiao He's orders, no one in the entire Shang Fang dares to disobey Liu Chang's orders, and what Liu Chang says is what he says. First he found some ploughs, rakes, shovels, hoes, double-toothed hoes, sickles, and so on.

Shang Fang even invited a few old farmers to personally demonstrate to Gongzi how to use these farm tools in the suburbs of Chang'an.

What makes Liu Chang feel helpless is that those simple farm tools basically have no room for improvement, and they must be improved, unless they are in terms of materials, there are already iron farm tools at the moment, but because there is not much iron, because wooden, iron, and even bone and copper are mixed, they can use whatever they have, and they will not be picky.

In Liu Chang's view, the only possibility of improvement seems to be the plow.

All these days, he has been looking at the usefulness of the plough in the field, touching his chin and thinking about how to improve it.

It is easy to copy it, but it is not easy to think about it yourself, even if it is a simple thing, it must be more difficult to come up with it than to copy something more complicated.

When the new textile machine with reduced efficiency and improved stability was sent to Xiao He, the prime minister was very happy.

They immediately began to prepare to use the prince's method to send the blueprints to various places, let the local people manufacture a large number of machines, and then recruit the displaced people to solve the problem of the displaced people.

Liu Ying, who was ready to praise her younger brother, was even happier when she learned that her younger brother was trying to improve his farm tools recently. When Liu Chang returned to the palace, he held Liu Chang's hand tightly.

"Eldest brother... Now that my father and mother are not in Chang'an, I am not greedy for any credit, I just want my father to know that I can cure the country, if you can make a new machine, I will definitely make it in large quantities, so that my father can see that none of his children are not successful. ”

It can be seen that Liu Ying is indeed very excited, and he has done a lot of things within his authority these days.

He is trying to really become a useful prince, not a prince who is full of empty words, empty talk about benevolence, righteousness and morality.

In the court, he met with almost all the ministers, asking these ministers to put forward their own suggestions, and the ministers were also a little helpless, in the face of the prince's request, more or less gave some suggestions in their own field, the prince rewarded these people, and collected these suggestions, and then the people around him came to negotiate to see if those suggestions could be implemented.

He was trying to show his ability, and Liu Chang's idea also made him very happy, if Liu Chang really had a way to make a machine that could increase food production, he would be able to do more.

Liu Chang was running into the cultivated land all day long, dirty, not quite like a prince, in the Tianlu Pavilion on weekdays, he was disgraced, in stark contrast to the princes around him.

"Look at you, you've become a mud monkey, and you don't know how to wash your face... Beware of the queen mother beating you up when she comes back! ”

Ruyi said with a smile.

Liu Chang didn't care, he raised his head proudly, the dirt seemed to be his medal, and he said loudly: "I'm covered in mud, but I'm doing things for the people of the world, you are so clean, what do you contribute?" ”

Ruyi was about to say something, when Gai Gong slapped the case violently.

"Childe Ruyi, someone will come, only look forward. One word, one action, gain and don't lose. The words are taken, the lines are taken, and the words are not taken, so the words are the words of the heart; The flower of the heart of the color is also; The heart of the angry person is also floating. There is a word, no line, and the stomach is false. Therefore, the head of the temple is the head of the line. Straight wood felling, straight people killed. No punishment and no name, born congenitally, so far it has not been completed... What does this mean? ”

Ruyi's eyes widened and he stammered and explained, "Such as. If you want to entrust someone with a heavy responsibility... Can you say that again? ”

"None of this! Are you embarrassed to accuse your brother? Copy the Sutra to me sixty times! ”

Ruyi lowered his head and whispered yes.

Liu Chang grinned, squeezed his eyebrows in front of Ruyi, and was in a very happy mood.

When the class was over, Gai Gong stopped Liu Chang.

He slowly wiped off the dirt on Liu Chang's face and hands with his sleeves, and wiped it clean.

"I know what you want to do, you are doing very well, and if anyone in the palace dares to mock you, tell me, I'll clean it up for you!"

"Hey, hey, okay!"

Liu Chang continued to wander around the cultivated land, although he knew nothing about cultivated land, but the basic hands-on ability was still there, and he soon realized that if the loom could improve its efficiency by using multiple spindles, why couldn't the plough increase its efficiency by multiple ploughshares?

It is easier said than done, and if only a few ploughshares are added, the plough becomes quite cumbersome and more laborious, and not only does it not increase efficiency, but decreases it. Liu Chang repeatedly observed the plough, and he finally found that he could use the principle of levers to change the straight wheel to the curved wheel, and the long wheel to the short wheel!

Also, find a way to add a few more ploughshares to this thing! Install a curved ripper hoop post behind the plough frame! Install another ripper at the lower end of the hoop! Install a ripper hoe in front! No! Two!!

When Liu Chang drew a design drawing and handed it to Shang Fang's people.

These people are stunned, this is a plough?? Did you hang all your farming tools on the plow? How many ploughing oxen do you need to pull this thing!!

Although the design drawings of the chief of the son are outrageous, but it still gives the craftsmen a certain inspiration, such as combining different farm tools, including changes to the straight wheel, etc., the craftsmen began to design quietly behind the scenes, the chief of the child is good at everything, but a little too bold, want everything, always pursue the greatest efficiency...

Hearing that the craftsmen had begun to make their own products, Liu Chang was of course very happy, and even the amount of food was much larger.

On this day, Liu Chang watched the craftsmen experiment with different farming tools in the ploughland, and only then did he follow Luan Bu back to the palace in the evening.

Just as he was about to enter the palace, someone suddenly shouted: "Liu Chang!" ”

Liu Chang was stunned for a moment, and turned around, but it was two and a half years old, looking at him with an arrogant face.

"You're Liu Chang, aren't you?"

The two men approached slowly, and the armor soldier at the door looked at them a few times, and then turned his head in amusement.

"That's me, who are you?"

"My name is Gentleman! This is my brother's city! ”

"You're bullying our sister while we're away?"

The two looked at Liu Chang with bad intentions, with a rebellious face.

"Huh? Which is your sister? ”

"Fan Qing!"

"Oh... The brother who complained about the ghost? ”

"Humph! If it's funny, I'll go and apologize to our sister! Otherwise, our brothers won't let you go! ”

Liu Chang smiled and rolled up his sleeves and asked, "By the way, I want to ask you something... You don't like to sue like your sister, do you? ”

"What do you say! We are all husbands who stand up to the sky! How can you sue an adult! Why do you ask this? ”

.......

"Wow...."

"Mother, we didn't do anything, he came up and beat us... I can't see with my eyes anymore..."

Fan Yan, with a blue nose and swollen eyes, cried and told his mother about Liu Chang's atrocities.

The people of Fan City on the side also wiped their tears and cried.

Lu Xiao had a cold face, listening to the two guys crying here, "Two people, they can't beat one younger than you... And the face to cry to me? Your father's face has been lost by both of you!! ”

"If your father were here, he would have hung you on the beams of the house and beaten you!"

"Still crying?!"

Hearing Lu Xiao's words, Fan Yan covered her mouth and sobbed silently, never daring to make a sound again.

"If you get beaten, then fight back next time! You are the sons of the Marquis of Wuyang, don't come to me to cry again! ”

Fan Yan and Fan Shiren left from their mother's place, Fan Shiren's eyes widened, and he asked, "Brother, my sister was bullied, and my mother went to reason in person... We were beaten, why did my mother still scold us? ”

"Shhhh It's okay, it's okay, don't tell anyone about today... If we can't beat him, then let's call Katsuyuki, Yafu, and Jian to help us! The five of us can't still get beaten, can we? ”
