Infrastructure is a problem that no country can ignore, and US imperialism has used this trick to solve the economic crisis.

The first step of New China's take-off is also to engage in infrastructure, and this behavior has also allowed New China to win the title of infrastructure madness in just a few decades, and any country in the world has to admire them when it comes to the word infrastructure.

Because the scale of infrastructure is too large, and too many manpower and resources are involved, it can lead to an all-round take-off from point to point.

Therefore, the current Datang does not need to think too much about high-tech or not-not, and can spend decades to build infrastructure with peace of mind, and when they can do a good job in infrastructure, everything else will be fine.

Li Shimin and Li Chengqian's mouths were wide open at this time, and they could almost stuff a fist into them.

They never thought that a simple road and bridge construction could drive such a large area.

In addition to being shocked, Li Shimin couldn't help but admire Li Yuanjing's vision, and couldn't help but praise: "That's true, not to mention the manpower required to build roads, road construction will inevitably use a lot of cement, stones and sand, just mining, manufacturing, and transportation, which requires a lot of manpower, just this one, I'm afraid it can solve the problem of eating millions of people!" ”

"Yes, this is the advantage of the imperial court, the production and manufacturing rights of cement are in the hands of the imperial court, if you don't want to be too troublesome, the imperial court will directly allocate the task, the cement workshop does not need profits, the imperial court only needs to bear the labor wages, there is no businessman to earn the difference, the imperial court can complete these things at the lowest price."

Of course, if you want to trouble some, it is not a problem, the early court already needs to invest, but the cement produced can also be supplied to the market, and the people have money, they may consider building better houses, that is, those who are about to leave, they also need a lot of cement, this part of the cement that is put on the market, will make the cement workshop self-sufficient. Li Yuanjing smiled slightly and reminded by the way.

"Good! Very good! Then take Guanzhong as a pilot first, and ...... first," Li Shimin nodded excitedly.

"Slow ......down" Li Yuanjing interrupted Li Shimin's words very unexpectedly, looked at Li Chengqian in Li Shimin's questioning, and said: "Prince, this plan is up to you, the requirement is to take Guanzhong as a pilot, how many roads to build, what specifications, it's up to you to decide, the goal is to be able to get as many people involved as possible, and at the same time within the controllable range, you only have half an hour's time, you don't need a detailed plan, just list a general framework!" ”

Li Shimin instantly understood Li Yuanjing's intentions, nodded with a smile, and agreed to Li Yuanjing's arrangement.

Li Chengqian looked at his father and King Zhao who were colluding with him with a confused expression, and suddenly felt that there seemed to be something in his heart.

The painful lesson of the last plan is still dangling in front of me, fortunately, it is Lingnan, if it is wrong, it will be wrong, and there is still a chance to remedy, this time it is Guanzhong, and you want to play the dead......

However, in Li Shimin's eyes, Li Chengqian did not dare to refuse, so he could only agree to it.

Li Chengqian squatted on the side and thought silently, although there is only a big framework, the things involved in it are not trivial, and more importantly, he has suffered a loss, so now he does not particularly understand the truth and does not dare to make a decision.

On the other side, Li Yuanjing muttered to Li Shimin in a low voice: "I think it is best for the imperial brother to be personally responsible for the six major classifications, or let the prince be responsible, one is that these things are very important, and the other is that the prince can familiarize himself with them in advance and know the importance of these things, and second, this may be the main governance direction of the Tang Dynasty in the next hundred or even hundreds of years, and I have to pay attention to it." ”

"Well, then I will be personally responsible, the prince will supervise it, and another prime minister will be in charge!" Li Shimin nodded, although he still didn't understand it a little, but now he also knew that this matter was not trivial, and there were so many aspects involved and the importance of his status that he could not disperse it to various ministries.

Of course, the final implementation still has to be decentralized, but the decision power cannot be given to them.

In this case, the status of the person in charge cannot be too low, although there is no problem in setting up a prime minister, but it is still that sentence, there are too many aspects involved, and a prime minister may not be able to control the field, so the emperor is personally responsible, and the prince supervises, with these two mountains rooted here, the people below naturally dare not have any complaints.

While deterring the underside, it can also cultivate the prince's ability and vision, I have to say, this is a new direction.

"What about the military? I see you've got a lot of categories on it! Li Shimin then asked.

"The Shangshu of each department is at the same level as the General of the Sixteenth Guard, which is a bit troublesome, so my idea is to upgrade the Shangshu to one level, and while maintaining the status quo of the military department, add the field military department, the internal guard military department, the logistics military department and the weapons department, so that the military department will have five small departments, which are responsible for different directions and tasks, each performing its own duties, and the Shangshu is responsible for coordination."

"What's the point of the existence of such a military department?" Li Shimin wondered, the military department will have functional conflicts with many new departments, who will listen to when the time comes?

"The ministries are still dominated by the military department, and the military department can formulate plans and arrangements, and the ministries are responsible for implementation, and there is no direct conflict between the two!" Li Yuanjing said that the Ministry of War was actually a civilian yamen, and it had no real power except for making decisions and plans for the emperor to approve for approval.

Even if their decision is passed, it is not for them to implement it themselves, but the Ministry of War is indeed the head of the world, and there is no way not to admit this.

They are more like a group of staff officers, who need to control the overall situation, and then tell the emperor where to do what to do, how many troops should be deployed, and even whose troops to transfer, unless the emperor has a different candidate, otherwise once agreed, it will be carried out according to the requirements of the military department.

Therefore, although the Ministry of War has no real power, no one wants to offend, otherwise you will be transferred to Lingnan one day, and you will not be able to find a place to cry.

"Hmmm! This plan can be given a try! Li Shimin nodded, dispersing the power of the military department, but also allowing the various departments to have checks and balances on each other, which was a good decision overall.

"Father, Uncle Wang, and the son have a general idea!" No one remembered whether it was half an hour, and Li Chengqian's voice interrupted the conversation between the two.

"Tell me about it!" Li Shimin asked with interest.

"Father, if Guanzhong is used as a pilot, Erchen believes that the first thing that needs to be built is the road from Chang'an to Tongguan, which is one of the most important passages in the Tang Dynasty, and according to the current situation, considering the development of the caravan in the future, Erchen estimates that this road will be at least five battles wide, so that four carriages can run in parallel, and this road passes through Xinfeng, Weinan, Huazhou, Huayin four places, as long as the imperial court plans the route, you can let the four places organize manpower at the same time to start, in addition, you can organize the surrounding counties to be responsible for transportation.

If the materials are sufficient, you can consider building a road in Longyou Road, and if the population of Longyou Road is insufficient, you can also mobilize manpower from Guannei Road to go over when the time comes......"
