Yan Lide also plunged into the research of cement, and Yan Lide wanted to study some ways to use cement, so that he could better build this city. And Jingwen also continued to inspect this county, this is his own fiefdom, and this is also the foundation of Jingwen. Even if you can't get along in the officialdom in the future, you will be relied on here, and you don't have to worry about the betrayal of the people here, because you have a life-saving grace for them. And the people here absolutely support Jingwen, as long as Jingwen does not rebel, there is no problem.

"Uhhh

A man carries a large bag of masonry and prepares to go up. According to what Jing Wen saw, this person should have to carry these bricks and stones to the top of the room, so that the people above could use these bricks. But Jingwen looked at this person very hard, which made Jingwen feel a little helpless. In ancient times, there were not too many construction machinery, and if later generations were afraid that there would be a crane, which could lift a large number of heavy objects, and then get it to a high place for use. However, in ancient times, a qiē had to be carried by one's own people, so it was very difficult.

"Aren't you tired?" Jingwen asked.

But the young man said, "I'm a little tired, but this is to rebuild our home, and of course we have to work hard." ”

Jingwen didn't continue to hinder him from doing things, but was just trying to find a way to reduce the pressure of this kind of processing. For the construction of ancient buildings, the most time-consuming thing is quarrying, transportation, and finally climbing. The problem of transportation has just been solved, that is, the use of cement as the main material for the construction of the city. The problem of quarrying, Jingwen used explosives to quarry, and the efficiency was increased countless times. And this ascent is the most difficult, because there was no crane in ancient times, so many things have to be carried on people's shoulders, which is very difficult.

"Well, since there were no cranes in ancient times, then I'll make a crane myself!" Jingwen said.

Jingwen is glad that he did not return his junior high school physics knowledge to the teacher. So now he's still able to figure out how to do it. In fact, it is not so complicated, that is, to make a pulley block, you can make a crane in ancient times. And the pulley block is not complicated, just make a wheel out of wood.

"You make the logs into a circle, and then you dig a groove out of the edge next to it to make a circle. After that, according to my design, you can form a pulley set. In this way, you can easily lift the heavy object and then make it into a crane! Jingwen said.

The construction workers also believed Jingwen, so they began to make zuò pulleys. And these construction workers are all people who have been doing it for a while. So knowing what to do, they immediately started to make the pulley set, and then connected it with rope according to Jingwen's method.

"Okay, you guys hang this upper pulley set on top of the house so we can use it to lift things." Jingwen said.

Soon, the builders began to put large bags of stones into the basket made of bamboo strips, and then they pulled ropes underneath.

"Oh my God! Can I pull it up all by myself? "Yes! Originally, there were no three or four people who couldn't carry it, but now one person can pull it up, and it's so easy? "Look. It was so high all at once, and it went up all at once. ”

"Lord Jingwen is really powerful, he actually made this thing, and it will be much easier for us to build a city in the future." "Yes! With Lord Jingwen. I'm afraid we'll be able to build our house soon, and we won't have to live in a tent for so long. ”

Although those people also lived in tents during the Turkic period, they were Han Chinese after all, and they were not so accustomed to living in tents. So I still want to live in a house. Now the house can be completed as much as possible, and this is all thanks to Jingwen. The gunpowder invented by Jingwen allowed the stone to be made as good as possible, and the cement could make the house stronger. And this pulley set can allow everyone to build houses as much as possible, which is all the changes brought by Jingwen, so the simple people think that it is Jingwen's merit.

"Brother Jingwen Xian, did you get this thing again? Hey, this thing saves a lot of labor, and it can save a lot of manpower. If the Sui Dynasty had these things to build the Grand Canal, I am afraid that it would have saved a lot of manpower, and the Great Sui might not have perished! Yan Lide sighed and said.

Almost all of Yan Lide's family participated in the construction of the Grand Canal, and they were well aware of the difficulties in the construction of the Beijing-Hangzhou Grand Canal in the Sui Dynasty. Although a canal has been built, it has almost hollowed out the old foundation of the entire Sui Dynasty. And the Sui Dynasty also levied countless conscriptions, allowing hundreds of people to help the government work. The people are very disgusted with forced labor, thinking that if you help the government to work for free for a month, it means that you are afraid that you will not only not be able to produce, but also have to be upside down. For the conscripts were not provided with food, and they were not paid. If there is too much conscription, there will be no food output, but it will have to be poured into it. Therefore, what the people hate most is forced labor, which they cannot bear. In order to avoid forced labor, many people would rather spend money in exchange for exemption from forced labor. In fact, many people have become displaced people in order to escape forced labor. Displaced people are a factor of instability in a country, so everyone is very worried about them. However, if there were these things invented by Jingwen at that time, it could save countless manpower, so that more people would not be bothered by forced labor and reduce the burden of the Sui Dynasty. In this way, what else could the Sui Dynasty have to perish?

"Brother Yan, don't sigh, there is no if in history!" Jingwen said.

"Hey, yes, history has no ifs. We're all worried about the ancients! I didn't expect that I couldn't see it clearly before you. Yan Lide said.

After this invention, Jingwen has successfully changed the pattern of the construction industry. In the future, the construction of government buildings may be able to save a lot of forced labor, so that the people can be proud of normal production. And conscription is the main culprit that can make a country ruin, so any monarch must be cautious. And Jingwen can be said to be a great merit, and he has made a great contribution to the stability of the country. This is also an inconspicuous thing, which can often change human beings and change the important reason for human history. Everything in the world is connected, and this is also another form of butterfly effect. (To be continued......)
