Jiang Wei bought a vacant land in Yunling Village, about 3,000 square meters, located on the west side of Yunling Village.

As for the previous house in the suburbs, Jiang Wei planned to use it as a laboratory to renovate.

After all, there are many chemicals that are dangerous and polluting for a long time, which can only be done at home with some small experiments with low risk.

In addition, Jiang Wei also plans to build two roads, the cement road from Yunling Village to Chang'an City, after all, the current carriage imitation vibration system is relatively bad, if the road is not good, he can't stand the bumps too much.

There is also a road, which is the road from the cement factory to Chang'an City.

Jiang Wei handed over this matter to Li Tong, Li Tong, as the only scholar in Yunling Village, has changed his thinking a lot in the past few months because of Jiang Wei's influence.

Because of the difficulty of the Tang Imperial Examination and the low acceptance rate. Coupled with the fact that his grades were not ideal, this forced him to give up continuing to take the imperial examination and chose to follow Jiang Wei.

Li Tong received this task alone, and showed a very high degree of execution, and he hired a thousand people on the same day to start construction on two potholed roads.

At first, the people in Chang'an City and the merchants who came and went didn't understand what they were going to do, so why did they dig the road down? Even many people are very dissatisfied with this, because the process of building the road has brought great inconvenience to the operation of their goods.

Most of these people, who were also businessmen, went directly to the county government to complain and demand that Li Tong immediately stop the destruction of the road. But the county government didn't pay attention to this time, and only informed them that the road was being built.

I have to say that Li Tong was prepared earlier, and his thinking was more cautious.

But the businessman was very puzzled, because usually the road is built to fill the road with soil, what kind of road is this excavation?

Not only the businessmen were puzzled, but the common people were also very confused. After three days, the teahouses in the wine shops in Chang'an City were also discussing this matter, because it was like a reward for human confusion, and they didn't understand how these people were going to build the road.

I don't know who inquired about the source, and only then did I figure out that it was made by the disciple of the Immortal Family who had been rumored for a long time. At this time, the people of Chang'an suddenly became enlightened, and they also felt that only the disciples of the Immortal Family could do this.

After all, what the disciples of the Immortal Family do, they never play cards according to common sense, and they have never heard of or seen anything they do, but they can always surprise people. For a while, the people began to look forward to it.

From the fourth day, Li Tong began to let people lay cement, and took protective measures to prevent someone from stepping on the undried cement without knowing it.

At this time, someone recognized that the paving thing was cement. Because the commercial plaza is a house made of cement. And this cement paving made many people feel surprised for a while, after all, most people have never seen this thing.

As soon as this news came in Chang'an City, individual businessmen smelled the huge commercial value of this cement. At first, the merchants thought that the cement was only suitable for building houses, and that steel was needed to build houses.

What a precious metal steel is, although steel production has increased a lot now. But if it weren't for the presence of those top elites, ordinary people or businessmen would not have been able to get steel at all. So they quickly lost focus on cement.

Now, cement can pave roads, and steel is not needed yet, which is different. But the vast majority of businessmen still have a wait-and-see attitude towards cement. As for being able to build roads, he thinks it's good to build roads, but he doesn't feel anything either. After all, it costs money to build roads, and who has nothing to do when they are full to spend money on cement to build roads? At most, it's just a road or two, and it's nothing.

But individual businessmen are different, and what he sees is different from other businessmen, from a different angle.

When the first section of the cement road was repaired, many people ran outside the city to watch the cement road, and when they found that the cement road was smooth and hard, they all said that the disciples of the Immortal Family did not disappoint them, and many of the Immortal Disciples' brains climaxed for a while.

This road is repaired, I can't believe it, and it's torture to think about the potholes and slippery dirt roads when it's not raining on weekdays.

With such a road, no matter whether it rains or snows, you are not afraid.

Some people think, how good would it be if there was such a good road in Chang'an City?

Soon, this section of the cement road attracted the attention of some dignitaries of the imperial court. Among them, Yan Lide paid special attention to this matter.

Yan Lide was born in a family of engineers and painters. He is good at architecture, craft, and painting. At this time, he was serving as the secretary of the Ministry of Industry, and he paid special attention to Jiang Wei, the nephew of his subordinate Xu Xiaoxian.

On weekdays, he also hinted at Xu Xiaoxian several times and pulled his nephew into the Ministry of Engineering. But they were all pretended to be confused by Xu Xiaoxian one by one, and Xu Xiaoxian could only express helplessness about this.

But Yan Lide did not give up his attention to Jiang Wei, the first time he noticed cement, he realized the importance of cement, the first thing he thought of was dams, bridges, and city walls.

When he found out that cement needed steel as a backbone, he didn't know the details very well, so he could only observe it slowly.

After all, he didn't have cement for him to experiment, and he didn't have cement before, so he didn't have any information for him to consult.

And when Jiang Wei paved the road with cement, Yan Lide immediately came to his senses, because this time, the cement did not use steel, but paved the road directly. When he learned about the very cheap price of cement, he didn't hesitate anymore.

The next morning.

Yan Lide stood up without hesitation.

"The minister has a book to play."

His Majesty Li Er seems to be in good spirits. A few days ago, the Baiqi Division found an alchemy master, and since taking this elixir, His Majesty Li Er felt a lot more energetic, and at the same time, the demand for intercourse has also increased a lot. It's just that there are too many beauties, and this indulgence directly makes His Majesty Li Er's energy continue to decline, so he has to eat one every morning and night, otherwise his energy will be a little insufficient.

"What did Yan Aiqing do?"

Xi Zigong asked Confucius, and Confucius said: "If you are stunned, if you are rotten and drive six horses." Zigong said: "How fearful" is? Zi said: "If we don't use the Tao to guide them, then we will be hostile, and if we are fearless." Therefore, the "book" says: "The people are only the state, and the country is solid." ”

"Yes, the minister heard that the people were uneasy because of the road construction. This is particularly concerned, and people dig deeper into it, and they find that a thing is called cement. This thing is a combination of water, mud and sand, but it has some extraordinary effect, it can make muddy water turn into stone, it can be wide, build roads, build dams, build houses, be strong and extraordinary, good quality and low price, it can be said that it is a rare strange material in the world. ”

"Therefore, I ask Your Majesty for approval to purchase cement for the purpose of paving roads, building embankments, and repairing city walls."
