A prince, a steward of the prince's palace, a carpenter of the prince's palace and eight guards with swords were standing beside a field, watching an old man in Li Yuanjia's village using a curved shaft plow.

From one end to the other, it is at least more than a hundred meters.

To put the heavy and huge straight shaft plow in the past, at least two oxen and two or three people were needed. The long straight shaft was placed on the backs of the two oxen. One or two people led the oxen in front, and one or two people in the back.

When holding the plow, everyone needs to concentrate and closely cooperate with the movements of other people or cattle.

Although the traveling speed is not slow, turning around is difficult, and it requires considerable skills to make the plow go in a straight line.

But now, with an ox and a plow, after just half an hour of practice, a fifty-year-old man can easily finish plowing the land in front of him. To say it is easy may be an exaggeration. After all, this is the beginning of March.

In the cold weather, the old man's back was already soaked through.

But there is no doubt that compared to the previous cumbersome straight-shaft plows, this thing definitely deserves the word "easy"!

So when the old man finished the last column and Han Shan asked him to stop, he seemed to have completely lost his mind. He just stood there stupidly, but his left hand was holding on to the

The plow refused to let go...

"Old man, how about this plow?"

After watching the plowing process just now, Li Yuanjia already knew what was going on, but now he still asked with a smile.

After waiting for a while and not getting an answer from the old man, Li Yuanjia couldn't help but frown. Han Shan quickly stepped forward and pushed the old man: "Old man, old man?! Your Majesty is asking you a question!"

"...Gudong!"

As if he suddenly came back to his senses, the old man swallowed with difficulty, then plopped down and knelt on the ground again: "Your Majesty, this thing, this thing..."

I stuttered and trembled, but I couldn’t say the next words!

At this moment, the old man's head was full of mush, because everything that had just happened completely overturned the common sense he had accumulated over decades of farming. This plow can still be used like this!

"..."

Rolling his eyes, Li Yuanjia felt extremely helpless.

So next, Han Shan stepped forward again, comforting and urging in a low voice. This time the old man quickly calmed down and began to stutter to answer Li Yuanjia's questions: "My lord, this thing is extremely easy to use and saves effort.

, only one cow and one person are needed to drive the cow to plow the land. Even for people who don’t have cows, using people to pull it will save a lot of effort..."

Luo Li talked a lot, but Li Yuanjia was not interested at all.

Could he know these things?

Compared with the old straight-shaft plow, the curved-shaft plow does have many advantages. Li Yuanjia has seen the old-style plow many times. The length of the old-style plow is usually more than three meters, and the straight shaft has to be extended to the length of two oxen.

On the shoulders, it is quite heavy; and although the curved shaft plow made of Chen Mu cannot be directly reduced by half as Li Yuanjia requested, it is still less than two meters long, and the curved shaft only needs to reach the back of the cow's butt.

The plow frame becomes smaller and the weight is reduced, which are the core advantages of the curved shaft plow!

Because in this era when the only material was wood, smaller size meant a significant reduction in weight. From a large plow that had to be pulled by two oxen and supported by two people, to a small plow that only required one oxen to pull and one person to support it.

, so not only a cow is saved, but also at least one person is saved.

Moreover, the reduced weight and smaller size mean that it is easier to rotate and more flexible to operate, and it can also increase the speed of plowing the land.

Therefore, technological changes are so important.

Just changing the shaft from straight to curved has brought so many benefits. Therefore, the emergence of the curved shaft plow can almost be said to be a very important revolution in the history of ancient agriculture, because it greatly improved productivity and liberated

There are countless working people. How many people are there in the entire Tang Dynasty these days? There is plenty of land for them to cultivate.

Especially in the south, paddy fields are the best places to use the curved shaft plow.

Because of its significant reduction in size, the curved-column plow will be the most suitable artifact for use in narrow paddy fields. Not only can it be pulled by cattle, but in this era of severe lack of animal power, people will also save more effort to pull it. Once popularized,

It will greatly accelerate the Tang Dynasty's development of the south, and eventually bear fruitful results in the middle and late Tang Dynasty and even the Song Dynasty...

In short, Li Yuanjia does not need an old man to summarize the advantages of Quyuanli.

"My father-in-law, tell me about its shortcomings."

Encouraging the other party with a gentle smile, Li Yuanjia smiled and said: "Don't always talk about how this plow is easy to use and effortless. We already know these. Now I want you to talk about the inconvenient parts of it, or what you think about it."

I want to make it better... Anyway, I just want you to find faults."

"Ah? Find fault? You don't dare to do this, this old man doesn't dare!"

"..."

Seeing the old man who immediately turned from excitement to fear because of his words, Li Yuanjia was speechless.

Well, his demands on others are too high.

So I winked at Han Shan and asked him to calm down the old man first, and then called Chen Mu aside: "Remember, in addition to this old man, find a few more experienced veterans.

, let them all try to use this curved shaft plow! You watch them use it, and then ask them individually what they think. The key is what is wrong or needs improvement... In the next period of time, give

I will continue to change it!”

"Your Majesty...do you want to continue to change this?"

Although he was a little scared, Chen Mu still asked after hesitating for a moment.

In his opinion, this curved shaft plow is already quite perfect. It is light and easy to use, and it is extremely simple to turn and change ground. It is more than ten times better than the original big stupid thing? Such a good thing, but also

needs improvement?

Isn’t it unnecessary?

"Of course, keep changing it for me!"

Looking sideways at Chen Mu, Li Yuanjia said calmly: "Go back and find Lao Han yourself, receive the five-guan reward, and then wait until everyone is satisfied with your improved Quyuan Li and there is no more faults to be found.

, I will reward you with ten more strings...Chen Mu, don’t let me down."

"...Gudong!"

At this moment, Chen Mu, who was swallowing hard and spitting, was still in the mood to understand the meaning of the king's words?

Five goals!

That’s five strings!

When he heard this number, Chen Mu's eyes instantly widened to the extreme, and his two pupils suddenly shrank to the extreme!

The two blacksmiths made the king's favorite iron pot, but they only received a reward of five guan.

and……

The next step is done, and there are still ten sticks left!

Seeing Chen Mu's stupid expression, Sun Peng secretly shook his head.

No matter what era, it seems that money is the most useful thing, especially for a low-status craftsman like Chen Mu, who has worked hard for a year in the palace, and besides having enough to eat, he doesn't know if he can save enough money...

...No, you definitely won’t be able to save it! You must know that even Chun Yan and Liu Mei, the two closest maids to Li Yuanjia, can save one or two pounds of money in a year, which is quite extraordinary.

So one can imagine how much these fifteen strings stimulated Chen Mu.

Think about it, this guy who can improve the curved shaft plow and then adapt the history of agriculture is just working hard for a reward of only a dozen dollars, but there are tens of thousands of dollars in his own warehouse waiting to rust.

Li Yuanjia couldn't help but shook his head secretly.
