July C1, 11.

Guo Shi came back first. There are not many places in Zhongmu County involved in the affairs of the Qunmu Division, and he didn't want to stay with a group of soldiers, so he went back to Xu Pingzhuang first.

When he arrived at the village, he asked the villager, saying that Xu Ping was testing the machine in the field and was not in the village. Guo Zhi was curious, so he was led by Zhuang Ke to the field.

It's still the same people as last time, with Xu Ping experimenting with a harvester in a sweet sorghum field. Sorghum grows taller and thicker than alfalfa, and the planting is also sparse, so the speed of the cutting knife has different requirements. It is now July, and it is almost the harvest season, and Xu Ping does not dare to delay for a day.

Li Zhang followed him to the field, chewed a sweet stalk to satisfy his hunger, and got tired of it, so he found a small pond to fish.

When Guo Shi arrived at the field, he saw Xu Ping and the others following the cattle in the middle of the field to harvest, and the two rows of cut sorghum fell in unison in the harvested field.

Bending down to look at the sorghum cut down on the ground, Guo Shi was also shocked there. The improvement of agricultural efficiency is the process of moving from relying solely on manpower to using animal power and then to using power. Guo Zhi has been an official in the past few years, and most of them are related to agriculture, and of course he knows what this means.

Leaving Zhuang Ke alone, Guo Zhi hurriedly stepped into the field and followed Xu Ping and his party.

Seeing Guo Shi, Xu Ping was taken aback: "Why did the master book come to the ground?" The height is uneven, the sorghum stubble is unusually sharp, and it is easy to hurt people, so I will still accompany you to the village to rest. ”

Guo Shi waved his hand and said, "No need, I was just going to see how you farmed." ”

This kind of machine that transcends the times, of course, Xu Ping doesn't want to be looked at by others, but he is not afraid of being discovered. To put it bluntly, in principle, the harvester is not so magical, it still imitates the action of people cutting crops, and it will not be regarded as a monster by the characters of this era. In fact, the real technology is in some inconspicuous places, such as the shape and speed of the knife, the angle of the blade, the conversion and transmission of power, these vague words are traceable in ancient times, but the specific data must be practiced for a long time.

What Xu Ping has is precisely the accurate data of these inconspicuous places, and it is just right to say it, making people speechless. In fact, Xu Ping took new agricultural machinery to the countryside to promote it in his previous life, and the onlookers often said that this was the case, and even said a lot of self-consciously better plans. What really shocked the farmers at first sight is that they are basically fully automatic control of unmanned aircraft, which is tall at first glance, but in fact they don't need it.

People don't think it's amazing what they can understand, they just think it's actually very simple, but they just don't think about it in that direction. Most of the agricultural machinery is like this, fundamentally simulating human movements, because human beings are naturally the most high-end technology in nature, and the best action will naturally be found in production, and agricultural machinery is just a relatively good action fixed and continued.

If there were no gears made of brass, not to mention Guo Shi, even Gao Daquan and these bankers would feel that Xu Ping was just spinning his brain faster, and the gearbox made them feel a little mysterious.

followed a walk back and forth in the field, and stopped at the ground, Guo asked Xu Ping: "This kind of farm tool is also made by the owner of the small village?" I've never seen it anywhere else. ”

Xu Ping said: "Yes, my Zhuangzi is too big, and there are few customers, so I have to make some farm tools to save manpower, otherwise where can I plant it." ”

Guo said: "Can the little farmer let me take a closer look?" ”

Where can Xu Ping say no?

Guo Shi bent down, looked at the whole machine carefully, pointed to the sealed gearbox and said: "I can see this farm tool in other places, but I don't know what the truth is in this iron box." And it seems that the mystery of the reason why this farm tool can be used is all in this iron box. ”

Xu Ping looked at him, and if he didn't understand the gearbox, he wouldn't give up, so he asked Sun Qilang to come up and open it, and simply let Guo Shi see it all at once.

Sun Qilang took a wrench, came up and took out the brass bolt on the lid of the box, the action was simple and skillful, and it was quite a bit of an old worker's style. His division of labor with Gao Daquan, these jobs are all done by him, perhaps because of his natural temperament, he also likes to do these.

The wrench and brass bolt made Guo Shi's eyes light up again, but he didn't say anything.

Looking at the box of gears in the gearbox, Guo Zhi was stunned for a moment and asked, "The inside of this iron box is made of stone?" ”

Xu Ping's face changed for a moment, and he said to Guo Shi: "The master book won't say that I have forbidden things privately." ”

Guo Shi said with a smile: "The imperial court bans copper just to curb extravagance and ensure that there is no shortage of copper for coinage." The small farmer is used to make farm tools, and agriculture is the foundation of the world, who will say anything. But I'm curious how you came up with the idea of using this for farming tools. ”

Xu Ping breathed a sigh of relief: "Gears can be used on water mills, why can't they be used on farm tools?" ”

Guo Zhi straightened up and sighed: "The little farmer is ingenious, but I can't do it." ”

Gears have long appeared in China, and by the Song Dynasty, even herringbone gears and gear trains were not uncommon, mostly wooden, iron and copper were also common, but they were basically cast. Guo Shi is good at inventions, and he has seen a lot of these things, and he doesn't think it's such a magical thing, but he thinks that Xu Ping can think of moving this kind of mechanism to farm tools.

Xu Ping's gears have technology not in the structure, but with brass precision pressing, so that the transmission is relatively stable, and the mechanical strength of brass can barely be used. Another one is lubricated with castor oil, which greatly reduces wear. You must know that castor oil is the best lubricating oil in nature, and most of the highest-end lubricating oil in Xu Ping's previous life still needs to be added in different proportions, which has an excellent lubricating effect.

This harvester, in Guo Zhi's eyes, he doesn't think there is any magic in which part is taken out alone, and there is no technology beyond the times. But when put together, it achieved an effect he couldn't have imagined. So although I can't say it, I always feel weird, and I can only come to one conclusion after thinking about it, Xu Ping, the little owner, is really ingenious and unmatched.

Looking at the cutting of two lines again, Guo asked Xu Ping: "Little farmer, your farm tools are so delicate and save a lot of manpower, have you ever thought about dedicating it to the imperial court?" Maybe you can get an official body! ”

Xu Ping shook his head resolutely: "I don't want to!" ”

In exchange for an official body, what kind of official will you change? Three shifts of service? Or is it a teaching assistant in Zhongmu? Needless to say, when Li Yonghe first became an official, Xu Ping knew what it was like. As for the teaching assistant, is this also an official? At this time, in the city of Tokyo, everyone who combs their hair and sharpens scissors is called a teaching assistant, which does not make people laugh to death!

To offer technology to the imperial court, the Great Song Dynasty court will generally give two rewards, one is to give money directly, and it is not a lot to give a thousand or two thousand, but Xu Ping will not earn it himself? What's more, the imperial court rarely gives money, and when it comes to giving money to the people, most of them give an identity. When you have less money, you will be given the identity of a monk and a Taoist, and if you have more money, you will be sent a few sets of blank official bodies, which has been said before, and it has little effect.

Unless there are special circumstances, such as the one who presented the copper immersion method to the imperial court, gave the official status, and also let the family be responsible for the management and technology of the copper mine. But this is not what Xu Ping wants, if he wants to be an official, he will go to the Jinshi.

Guo Shi saw that Xu Ping replied resolutely, and knew that he was not here, so he stopped talking. If you are unwilling to give farm tools, the official will not force you, and naturally there are other ways for you to play a role.

Although this dynasty has strict management of the people, it is not harsh after all.
