Long Xin Yutu rushed back to Yanqi Kingdom, but what Long Xin Yutu didn't know was that when he returned to Yanqi Kingdom, the entire Yumen Pass of the Han Dynasty had entered the final stage of sorting.

As the successor to the lord of Yumen Pass, Zhao Er is currently discussing the entire Yumen Pass with Wang Luo.

"When will the final work be completed?" Zhao Er asked seriously.

"It will be completed tomorrow, and other work is about to begin winter this year. According to our plan, winter will affect the structure of concrete, so we will not build in winter. However, in winter, we will store and prepare the entire construction materials, and the accumulation of materials will continue to be carried out at that time. However, considering the living conditions of the city, the materials will be stacked in the northeast direction." Wang Luo immediately spoke.

"My wife, I'll trouble you this time!" Zhao Er nodded immediately.

"Don't worry, Lord Zhao, I can't say anything else. This time it's related to the leader's marriage. If I don't pay attention to it, I'm probably going to be stripped of life." Wang Luo joked, and of course he knew why Zhao Er was nervous.

Because Yumen Pass will soon receive the envoys from the Tang Dynasty, and not only the envoys from the Tang Dynasty, but also officially open to all foreign merchants, which means that at that time, there will be at least thousands of merchants in Yumen Pass alone.

This is not because of the increase in these merchants, and the other members who followed it. What's more important is that when Guazhou is officially handed over to the Han Dynasty, many of their merchants in Guazhou will definitely settle in Yumen Pass in the Han Dynasty.

So Wang Luo has a heavy responsibility on his shoulders now, just like all the housing in the entire Yumen Pass. In addition to the houses prepared for the families of these craftsmen and the more than a thousand people who originally followed the general, Wang Luo and the others had only one thousand extra houses!

What remains are a large amount of area without construction, which means that these areas are absolutely impossible to build at least this year.

If you want to build a new house, you have to wait until you go to the Urban Industrial Bureau for approval next year.

Then, the price of selling these thousand houses alone is probably an astronomical figure!

Of course, these thousand houses are just houses to live in, and do not include those commercial banks built along several streets of Chang'an City. The buildings of these commercial banks are all based on the European-style buildings mentioned by the leader.

Wang Luo didn't know what the continental style was, but it has to be said that this architectural style can make use of their concrete advantages to the greatest extent. It uses very little wood and more stone, but stone is more decorative on the surface.

All the inner parts are made of concrete structure.

In fact, the reason why Huo Gang used such a building is naturally because first of all, the Chinese garden style is not suitable for this Western Regions because there are too few trees. Secondly, the pure wooden structure was in the ancient state of low fire protection. Once it caught fire... then you don’t have to think about the result.

It’s really not a joke if someone sets fire, it’s probably impossible to have half a city.

Continental-style buildings are relatively simple. It is easy to rescue when a building in this style of buildings catches fire, and it is not easy to produce a fire that burns half of the city at one time.

Another reason is that the glass used in this kind of building is relatively small. At present, they cannot produce too large glass. It is not that it cannot be produced, but that it is unnecessary and the cost is too high. Naturally, these shops cannot use such glass.

As for whether anyone is willing to use such large glass later, that is what happened later. At that time, it will be customized. As long as the money is paid, these factories in Huogang Industrial City are willing to sell anything.

Therefore, the most beautiful thing in the entire Yumen Pass is these main streets. In addition, other areas without buildings have been surrounded by mud walls, and there is no way to see the bare land inside.

The hardening work of the street has been completed, and every day there are personnel responsible for cleaning the entire street. It can be said that the entire city suddenly became extremely clean. What impressed Wang Luopei the most was the sewer system designed by the leader and the septic tank that handled the feces outside the city.

It is said that the fertilizer after treatment can be used directly in the land, which can increase the fertility of the land. They all know this, but Wang Luo has studied the treatment and design principles of the septic tank for a long time.

He is not very professional in this aspect, but Wang Luo's current research on architecture is definitely ahead of everyone in this era.

Especially the Great Hall, which will start construction next year, will be their main building within the next two or three, and will be completed within the first five years, or even the speed of completion will be faster than the city walls.

Because there are some materials, after the city wall is completed, it is not convenient to transport them to the city.

In fact, it is because of this that the south city gate of Yumen Pass, the Zhuque Gate opposite the monument, the Zhuque Street, which is the entire central axis of Yumen Pass, the Great Hall, and the villa where the leader lives are all on the same central axis.

There are two such central axis, namely the Zhuque Gate and Xuanwu Lake in the north and south, and the Qinglong Gate and Baihu Gate in the east and west.

There will be no city gates in the north wall, because outside the north wall is a lake that is still expanding further north. The area of ​​the entire lake is already very large. Because there is no north gate, this lake is simply named Xuanwu Lake.

Of course, Wang Luo knew that there was no city gate on the north wall on the surface, but to be precise, there was a secret passage on the north wall, but outsiders did not know about this passage.

"Then please pay more attention to Yumen Pass recently."

"Don't worry, we have prepared everything we should prepare, and we have covered everything we should cover up." Wang Luo said with a smile.

"By the way, how long will it take for our city wall to be completed?" Zhao Er asked curiously.

"If nothing unexpected happens, it will be completed next year." Wang Luo thought for a while. Zhao Er was the lord of Yumen Pass City, so this kind of news can naturally be known.

"Next year?!" Zhao Er took a deep breath. Didn't they just lay the foundation? The main building of the entire city wall has not been built yet, and it can be completed next year?

"It's true, everyone, our city wall is more majestic than the city wall of Chang'an City. You just finished the foundation this year and will be completely completed next year?" Zhao Er was a little unbelievable.

"Of course, you should know how fast our concrete construction speed is. In fact, what limits our construction progress is nothing more than the cement output and steel bar output. However, the steel bar output has already risen. After a winter of production, the stored quantity will definitely keep up with the construction next year."

"You don't know that those guys in Industrial City have been crazy lately." Wang Luo shook his head slightly. The expansion speed of Industrial City is too fast, almost Yang Wu, oh, that is, Yang Laowu, he changed his name. Because it is said that this guy has become an official, Yang Laowu's name is not very good, so he changed himself to a homonym, called Yang Wu.

Yang Wu has found him more than once, and asked them to build the road from Industrial City to coal mine next year. Otherwise, the coal excavation and transportation speed would be no longer as fast as their firing.

After all, now they need coal to burn everything.

You know, there are at least 30,000 or 40,000 coal workers dig coal every day in the coal mine. Fortunately, there is an open-pit coal mine, otherwise, there would be no such large amount of mining.

"Even so, you guys are too fast? Can you build it in one year?" Zhao Er was a little shocked.

"We adopt a brand new construction method." Wang Luo thought about it, but did not hide it, because starting work next year, it would definitely require the cooperation of the city lord Zhao Er.

"This was also proposed by the leader. First, the reinforced concrete structure about 5 meters thick on the outside of the city wall, and then the reinforced concrete structure about 3 meters thick inside the city wall. As for the middle part, a small amount of cement, river sand and gravel are mixed to mix. When the thick steel bars are fixed into different blocks, they are directly filled." Wang Luo said quickly.

"This... fill directly? Can this be solid?" Zhao Er was a little confused. In this case, can the city wall become solid?

"Haha, let alone the five-meter-thick reinforced concrete, there is almost no one who can destroy it. Just talk about the parts in the middle. Although they are just a small amount of cement, river sand and gravel, although they are not as strong as concrete, after it is completely dry and compacted, in fact, the wall in the middle is much stronger than the old city wall in Yumen Pass before."

Wang Luo shook his head slightly, actually they had done the test.

The filling part in the middle does not seem to be strong, but this is relative. You have to see who you compare with. It is definitely not as strong as that of reinforced concrete. However, if you compare with ordinary blue bricks, it is much stronger.

So overall, there is absolutely no problem.

In fact, the filling part in the middle is a bit like the layer of things under the tiles of house decoration in later generations, but gravel is added inside. After it is completely dry, the solidity is not too bad.

Of course, there is another reason for filling like this, that is, the abandoned city walls of Yumen Pass can be filled directly.

To be honest, for this era, not to mention that the middle stuff is filled with these things, even if the middle stuff is soil, the strength of the entire city wall is unquestionable, and the thickness of concrete is not something that can be dealt with in this cold weapon era.

When the future transcends the age of cold weapons, there is almost no need for the city walls to exist.
