After the Laba Festival, Lu Ye returned to the prison again. Pen & Fun & Pavilion www.biquge.info

There is no need for Lu Ye to do too much about the things in the recording room, perhaps because Hu Zuo has explained, Yi Chen and Wei Ku have not had much to do with Lu Ye since Lu Ye arrived.

And Lu Ye was also happy to be idle, and he walked around when he had nothing to do in the prison. Occasionally, I met those craftsmen of the older generation, and I had a very lively exchange with them.

Originally, those old craftsmen still didn't think much of Lu Ye before, thinking that a young man of this age could know much about us things.

Lu Ye passed by before, occasionally asking some things about these craftsmen, and then listening honestly to their experiences. In the face of these old craftsmen who are busy all day long, Lu Ye still has respect.

There are quite a few craftsmen of the older generation in the Hundred Workers' Prison, and most of the things in the recording room don't need Lu Ye to worry about, and Wang Dong, who was worried before, has not come to trouble Lu Ye until now.

Have fun.

"Uncle Jin, what are you doing here?" Lu Ye sat in the courtyard, looking at the work of several old craftsmen who seemed to be building a kind of plough, Lu Ye looked at the things they had created, and felt a little strange.

As we all know, what prevailed in the Han Dynasty was a kind of long straight plough, which was not flexible enough to turn back when ploughing the land, and the soil was laborious and inefficient. It was not until the Northern Dynasties that the short plough appeared.

And now these top craftsmen who will be overseers seem to be building a kind of short-wheel plow, but they seem to have encountered some difficulties.

This one called Uncle Jin, whose full name is Jin Xin, is the leading craftsman in the Hundred Workers' Prison, and he is quite accomplished in the manufacture of agricultural tools.

Jin Xin's sideburns were slightly gray, and after a day or two of getting along, this old man with extremely superb craftsmanship also had a good impression of Lu Ye.

Lu Ye didn't talk much, but every time he talked to Jin Xin and these craftsmen, he had a kind of respect that no one else had. It is precisely for this reason that Jin Xin admires this young junior very much, and when he heard Lu Ye's question at this time, he also had a smile on his face: "Spring ploughing is about to begin, let's make some farm tools, and then Your Majesty will use them when he sacrifices to the sky." ”

As for the royal family, these things need to be prepared in advance.

Lu Ye also nodded when he heard this.

Every year, the emperor needs to hold a ceremony to worship the heavens, and then he will do some farming, but everyone knows these things. Although it is a formality, for these officials below, it still needs to be taken seriously.

"But I see that this thing you make doesn't seem to be the one I saw in the past." Lu Ye asked with a frown.

Jin Xin also nodded when he heard this: "Well, it's a little different." We found the current rake a bit difficult to operate, and thought about changing it. You see, now that we've made this thing a little shorter, it takes a lot less effort. In this way, the efficiency will be much improved. ”

When Lu Ye heard this, he thought that the skills of these craftsmen were really powerful, but they still didn't dare to stride forward, all they thought of was turning the long plough into a short plow, but they didn't think that if they turned the long straight plough into a curved plow.

In those days, farming was a top priority, and there were no pesticides, no fertilizers, and no harvesters. Farming and harvesting are troublesome.

When ploughing the land, it is not animal power, but human power.

Middle-aged labor is really the breadwinner of a family.

Lu Ye looked at Jin Xin and several old men with smiles on their faces, as if he had overcome the last problem. Lu Ye pondered slightly, if he put forward the principle of Quyuan plough at this time, how much impact would it have on the current Xu Ducheng?

"Old man, you see if you change this short plough again...... Wouldn't it be more convenient? ”

Jin Xin smiled proudly: "Zihang, you don't understand this thing." Like the long straight plough we used before, not to mention the difficulty of operation, even the direction is very difficult to master. And our short-pitched plough after transformation will not have such confusion. The difficulty of using it is greatly reduced. You still want to change, could it be more convenient than now? ”

Jin Xin is still very confident in what he has invented.

When Lu Ye heard this, he didn't say anything, but just looked at the short straight plough that Jin Xin and the others had improved. Before Qu Yuan Li, Lu Ye chased a girl from the history department in college, and once made up a history of the Tang Dynasty, and Lu Ye also had a profound influence on Qu Yuan Li.

"Old man Jin, look, if we are on top of this rake, add plow evaluation and plow construction ......."

Before Lu Ye could finish speaking, Jin Xin interrupted him with a confused face.

"Wait...... What is Plough Appraisal and Plough Construction? ”

Lu Ye patted his head, thinking that he had accidentally taken out something that had already appeared in the later life.

So he hurriedly explained: "This is the name I gave to these two parts, and the plow review is ...... a rectangular wooden frame resting on a plough arrow; The plough is a curved wooden wedge that rests on top of the plough. ”

Jin Xin was confused: "Then what is the function of these two things?" ”

"It's much easier to control the depth of the farmland. The plough arrow goes downward, and the ploughshare goes deep into the earth. If the plough is raised, the plough arrow is upward, and the ploughshare is shallow when it enters the soil. Lu Ye said.

After hearing this, Jin Xin pondered for a moment, and then turned his head to look at the old guys beside him.

"What do you think...... Is this kid talking about this method feasible? Jin Xin thought about it in his head, but there were still some joints that he didn't figure out. But Lu Ye's two sentences already gave Jin Xin a feeling of enlightenment.

Lu Ye didn't give them more time to digest, and then said: "Let's look at this short plow again, it has become more convenient to use force, but the control is still not very different from the original long straight plow." Wouldn't it be better if we changed this straight to a curved one? ”

Jin Xin frowned again: "Qu Yuan? Why did you change it to a meander? ”

Lu Ye said: "Jin Lao, you see, we will change the straight and long wheels to curved wheels and short wheels, and install a plow plate that can rotate freely at the head of the wheel, which not only makes the plow frame smaller and lighter, but also convenient to turn around and turn, flexible operation, and save manpower." Wouldn't that be more convenient? ”

When Jin Xin heard this, there was suddenly a look of surprise on his face.

"Try it, let's try it!" A top craftsman like Jin Xin was originally quite familiar with farm tools, but at this time, Lu Ye mentioned it a little, and he felt that this method was feasible.

For a while, he couldn't take care of Lu Ye at all, and just thought about taking all the new ideas in his mind and putting them into practice.
