Progress is fast throughout the site, and because resources are limited, the construction categories are also divided by grades.

As far as the current Datang is concerned, vehicle manufacturing is obviously the first priority.

Because only with more vehicles can you build other tasks faster.

In the same way, the construction of machine factories is ahead of vehicle manufacturing, and it goes without saying that it makes more sense to invest trucks in increasing production capacity than directly in construction.

Moreover, this investment is not long-lasting, at best, with the number of 100 trucks, a maximum of two months is enough, and then at least 80 of these trucks can be put into construction.

Bulldozers and trucks have become the two most common vehicles on construction sites.

The rollers are of no use here, and although they need to be compacted after the excavation of the foundation pit, they are too large to be suitable for use here.

Moreover, the construction of the factory now, it is not like the later generations to dig a big pit directly, but like ordinary people to build a house, only dig a pit in the place involved in the foundation, in terms of compaction, it still needs manpower to complete.

However, the amount of work is not large, even if it is manpower, one day is enough.

Qu Tu Zhongxiang soon lost interest in architecture, because there was nothing to see.

After the foundation pit is done, it is directly on the ground to make a base, cut it with bricks, and then after three layers, it is built with double-layer bricks, and then it is to hit the bottom ring beam, which is simpler.

The finished steel frame is placed on it, fixed on both sides with abrasives, and then the live concrete is poured into it, poked with a stick, and it is finished after it dries naturally.

Such a simple, boring process, as an inspirational Qu Tu Zhongxiang of today's Academy of Sciences, is simply a waste of time.

A few days later, Qu Tu Zhongxiang found a new entry point, a truck, a bulldozer.

The truck won't be here for long, but while they were unloading, Qu Tu Zhongxiang still circled around the truck, and sometimes boarded the truck to take a look at the internal layout, but some of the more core layouts, he couldn't see it, so he couldn't disassemble the car here, right?

Besides, those current drivers, well, no one knows how to repair cars at all, they don't even understand it, they only know how to drive, and they can't even be called old drivers, all of them have been trained by recent assaults.

It was that bulldozer that became the object of Qu Tuzhongxiang's research.

The bulldozer is parked on the construction site, working during the day, and naturally stopping at night.

But again, he can only see a rough idea, and in more detail, he can't see it.

Just as the roof ring beam was about to be built, another big man was welcomed on the site.

The number two person in Datang.

Who is the number two? Some people say that it is the 'general leader' of the cabinet, Fang Xuanling, and some say that it is something else, but this No. 2 person has nothing to do with the cabinet.

It may have been said before, but now, this number two person is undoubtedly the crown prince.

Since becoming the crown prince, Li Chengguang's life has become more busy, not only to grasp every time to study, but also to seize every opportunity to prove himself.

The position of the prince is very difficult to do, far from being as easy as ordinary people imagine, although Li Chengguang, the crown prince, is covered by Li Yuanji, and has helped him solve the problem in many ways, but even so, Li Chengguang still feels very uncomfortable.

When you are a prince, you are afraid that there is a way to solve it, if you don't do it, you won't make a mistake, and if you don't do it, you won't make people complain.

But the prince can't do it, but the prince can't help it, even if he knows that there will be problems, he has to think of a way to minimize the consequences.

Therefore, now Li Chengguang needs to constantly go out, constantly inspect, and replenish himself, while also brushing up his sense of existence, and constantly accumulating his prestige through this form.

Although Li Chengguang felt very tired, in his heart, none of the princes of all dynasties had a better environment than him.

All obstacles are cleared, and you don't have to worry about others staring at your position all the time, as long as you don't die.

In fact, in this case, a new problem will arise, the prince lacks a sense of struggle, and it is okay now, in case there is a need for struggle in the future, the inexperienced prince will be completely blinded.

But it's just a subconscious question, and no one has raised it.

Because of the accident when he inspected the railway construction site before, and after that, Li Chengguang's specifications for going out have increased a lot, and the forbidden army alone has increased to as many as 1,000 people, and this security specification is naturally only under the emperor.

"Just send some of them in!" Li Chengguang waved his hand to stop the guard's posture of planning to rush in.

Ma Wu is Li Yuanji's person, so naturally it is impossible to follow Li Chengguang's side for a long time, and Ma Liu also has his own tasks, so he selected someone from under the two to serve as Li Chengguang's general escort.

Of course, there are also many secret guards who are mixed into the guards, these people are not only protecting Li Chengguang, but also spying on others, they are the last guarantee, and there are no countermeasures to prevent the guards from defecting.

"Your Highness, there are many workers inside, and the background is ominous......" Chen Zhi, the chief escort, hesitated, wanting to refuse this order.

It is a major matter of safety, and he must not pay attention to it.

"Jiang Guogong has been conscientious and loyal all his life, and he has never had evil deeds, and now his descendants are upright and honest!" Li Chengguang said calmly.

Jiang Guogong naturally refers to the late Qu Tutong, although the skills of the two descendants are not as good as Qu Tutong, but they did not embarrass the Qu Tu family, although there are many people outside who say that they do not pay attention to the identity of the nobles and do those humble things to make money.

But this kind of spirit is exactly what the royal family values, don't cheat, don't rob, don't steal, don't cheat, rely on your own hands, do what you can, don't eat and wait for death, shouldn't this be encouraged?

Without giving Chen Zhi time to hesitate, Li Chengguang directly ordered the coachman to move on.

Seeing this, Chen Zhi had no choice but to follow Li Chengguang with his guards and protect him by normal means.

Qu Tushou and the others had already received the news, and they were also waiting in front of the door of the construction site at the moment, but they waited left and right, and did not wait for the guards who came to inspect first, but directly waited for the prince's team.

Qu Tushou is also a nobleman, and some etiquette or something is still very clear, he can naturally see that it is not that the guards do not follow the rules, but that the prince does not want to do that.

A very ordinary thing, but in Qu Tushou's view, the meaning contained in it is different, which means that the prince has enough trust in himself, trusting enough to trust his own safety.

For a while, Qu Tushou was also excited.
