Don't have to wait two days later, on the second day, a large number of ships continue to transport materials through the canal and pile them up outside the Jinguang Gate, and then they are guarded by people, such as stones, sand and other things Everyone knows, but the use that can be thought of is for laying the foundation.

At the same time, a large number of people outside the Jinguang Gate came here to register and sign the contract.

Li Ke arranged for a hundred people to register here. In ancient times, engineering relied on a large number of people.

The number of registered people lasted until the afternoon, and in the evening, Tian Meng summed up Li Ke, not counting the 7,000 strong laborers among the 10,000 displaced people who had been collected before, and the number of people who worked this time alone, there were 20,000 people registered today, including about 3,000 women who cooked.

About 30,000 people, which is enough in the early stage.

Early in the morning of the third day, Su Dingfang had already sealed off the western section of Suzaku Hengjie before the curfew was lifted, and all the people had already gathered outside the city in advance, and the master who had already prepared would have a total of 24,000 strong laborers, divided into 240 groups according to a group of 100 people. Then it is divided into different tasks such as transporting raw materials, mixing raw materials, priing open the original floor tiles of Chang'an City, and tamping the foundation.

Li Ke didn't have to worry about these aspects, but he still came over today, standing on the city wall and watching the people below command the work.

As the main pedestrian street in Chang'an, the roads under these stone slabs have actually been pressed very tightly, but Li Ke still made a large number of cast iron ingots here to lay a solid foundation.

With the sound of these laborers' horns, the dull sound of "bang" and "bang" kept coming, and the master in front was measuring the laying distance by prieing up the intact bluestone slabs.

Two hours later, Tian Meng sent a message to Li Ke, "Your Highness, we only need to lay about two hundred and sixty steps of concrete pavement from the city gate, and the remaining intact bluestone slabs can complete the laying of the remaining pavement." ”

Datang step is a unit of length, one foot of Datang is 10 inches, one step is equal to 5 feet, one zhang is equal to 10 feet, and one mile is equal to 300 steps.

One step is the average length of the left and right feet in a row. Li Ke once took out a modern ruler from the space and converted it, one step is about 1.52 meters, and one foot is about 0.31 meters, there may be errors, but it is basically this number.

"Yes, I will completely lay out these two hundred and sixty steps today and show everyone that!" Li Ke said with a smile.

"Yes!"

With Li Ke's order, these 260 steps, including the inside of the city gate, all began to be tamped, paved with sand, paved with gravel, and continued to be tamped, followed by mixing concrete.

Chang'an City has a perfect water system, so it is not a problem to take water, and the craftsmen who have already tested it weigh it with a large scale according to the proportion of the test, and then mix the gravel, river sand, and cement according to different proportions, and then use a wooden frame to lay a frame, and then start laying concrete inside.

The amount of concrete mixed at a time is not much, because there are too many uneven stirring, by seven or eight strong laborers from all directions to make sure that the mixing is sufficient, and finally poured into the wooden frame, and then there are people wearing special leather boots directly into it, holding a wooden stake in their hands and constantly stirring in it, to avoid leaving any air.

There were a lot of people watching the excitement around, they didn't know what they were doing, it felt like mud, could this thing build a road?

At last the masons stood on specially erected planks and began to smooth the whole road, and by nightfall, the three hundred meters of the road were almost complete, and at regular intervals the road there were expansion joints left in the middle of the special cork planks.

Early the next morning, as soon as the gates were opened, someone took straw and paved the entire pavement with straw from the erected boardwalk.

The materials that started in the past two days have been transported to the city yesterday, and the Cao Canal is connected to many aqueducts in Chang'an City, but all the canals have iron fences at the entrances to the city, and people cannot enter.

In the past two days, cement will not be used for the time being, but all the stone slabs in the western section of Suzaku Hengjie will be pried up, and then the foundation below will be thoroughly laid, and then laid.

The project here is proceeding in an orderly manner, but the eyes of the people in the entire Chang'an City are a little unpredictable, what is Li Ke playing? They have already sent people, and even come to the scene to see in person, what kind of gray things, like mud mixed with stones and sand, can be used as a road?

Isn't this self-deception?!

The eldest grandson Wuji and the others are all waiting to see the joke, but they don't know how many days it will take Li Ke to open this road that was about 300 steps long and repaired first?!

There are a lot of people staring at it every day.

It's just that what they didn't expect was that Li Ke didn't wait long at all, on the second day, some water was sprinkled on the road, and on the third day, it didn't move, and on the fourth day, Li Ke announced that this section of the road could be opened to the outside world!

Li Shimin, who knew the news, couldn't bear it anymore: "Isn't this nonsense?!" Come with me to the scene to see, who is this fooling? Mix it with mud and a little stone and sand to be the road? ”

Because it happened to be a court meeting, Li Shimin simply took almost all the ministers directly to the project site, and Li Ke showed it to everyone today, so he was naturally at the scene.

Before Li Ke started here, he got the news that Li Shimin had brought the minister here, he rolled his eyes, and immediately said in a low voice: "Quick, announce to the outside world that the road will be temporarily closed to the public today, and it will continue to be open after a while." ”

Tian Meng decisively went to announce.

Su Dingfang: "......" He was behind Li Ke, Li Ke didn't hide it at all, Su Dingfang suddenly felt that there was something square, Li Ke's behavior was ...... Is this considered a deception?

He suddenly thought of the Chang Nei Servant beside His Majesty, and he didn't know how the Chang Nei Servant persevered.

The people on Li Ke's side just announced the news to the people around them, although the people are strange, but there are not many people who leave, and there are many people who watch the project here every day.

And this news quickly reached the ears of Li Shimin, who was halfway through, he was stunned for a moment, and then a little angry, what is this kid doing? Everyone came out, and Li Shimin naturally couldn't return, so he still went straight to the project site.

When Li Shimin came, Li Ke pretended to be surprised and asked, "Dad?" What are you doing here? ”

"How did I get here? I'll come and see the road you built! Li Shimin said angrily.

"This ...... Dad, what are you doing here? The road hasn't been repaired yet. Li Ke glanced at the ministers behind Li Shimin, and immediately said with a look of embarrassment.

"Oh? Is it? It's not repaired, it's not repaired, aren't you already going to open it for use? Li Shimin sneered and asked without changing his face.

"This is Erchen's test, Dad and the ministers, this is the construction site, there are many people, please go back, it's not safe here, it's too dirty, and after the maintenance is done another day, Erchen will definitely bring everyone here." Li Ke said "hurriedly", and as he spoke, he reached out to hold Li Shimin's arm and was about to go outside.

Li Ke is like this, Li Shimin "chuckled" in his heart, this kid can't be playing something, right? But even if you mess up, you won't hide it and won't let yourself see it, right? This is less than 300 steps, and it is not that Chang'an City has been repaired, even if it is smashed, there is a chance to redeem it.

After hesitating for a moment, Li Shimin didn't force him to see it, but he couldn't just leave, but stood where he was and said: "Oh, what you said makes sense, but you can't show people this path yet?" ”

"Well, not for the time being, but don't worry, the craftsmen of the sons have developed a new thing, which can mix gravel and river sand and finally become a whole like stone, which can be used to build roads, build cities, and build bridges! Even the cost may be a little high, and Erchen is not also experimenting. Li Ke said "embarrassed".

Li Shimin felt that he understood, this kid should want to bypass those quarries and masonry yards, and then make something new, and now it seems that this new thing should have failed.

"Oh, the test is right, do you have any shortcomings here?" Li Shimin asked quietly.

"It's just that there is a lack of some slate tests." Li Ke was overjoyed, hey, his father is so cooperative?

"I heard that there are still some stone slabs left in the project of Daming Palace, or I will bring them to you." Li Shimin felt that he had guessed, this kid really had a problem, forget it, help him.

"The minister is against!" The eldest grandson Wuji jumped out directly!
