Maybe he himself didn't realize that as a dignified Crown Prince, his heart would rise and fall, and he would even be cautious about his minister's words.

Looking at Li Chengqian who looked forward to it, he was not as aloof as His Royal Highness. Yang Fan thoughtfully took a sip of tea and asked:

"His Royal Highness wants to buy the cement formula just to improve his official status?"

Li Chengqian collected his thoughts and said solemnly: "Under the hard work of my father, the Tang Dynasty is now at peace and the people are stable."

"But the territory of the Tang Dynasty is increasing day by day. Like the current Southwest Protectorate, it takes ten months to transmit messages from the border to Chang'an City."

"If it is to transport goods, it will take more time, which is extremely detrimental to the stability of Datang's rule in Tubo."

"I can even say bluntly that if this status quo had not been changed, Marquis Zhongyi's strategy would not have been able to be implemented well, because Tubo was not far away and Datang's control was too poor."

Yang Fan glanced at Li Chengqian in surprise. He really didn't expect that this weak Crown Prince would be so knowledgeable.

Yang Fan also told Wu King Li Ke about his thoughts at the beginning.

Since we want to build a factory and a trading center in Tubo, of course the road must be widened and leveled.

Yang Fan never thought that he could build a cement road leading to Tubo because he knew that this project was too huge.

The manpower and material resources consumed were absolutely astronomical. After all, the Tang Dynasty did not have as modern machines as later generations.

With the productivity and industrial base of Datang, it had not yet reached the point of mechanization.

Of course, Yang Fan cannot make a big leap forward in this era. If he takes too big a step and directly promotes mechanization, he may be in trouble.

However, since Li Chengqian proposed it, Yang Fan did not need to hide it: "His Highness's idea coincides with my original idea, but it is a little difficult to implement."

Li Chengqian didn't expect that Yang Fan had the same idea as him, and he was immediately overjoyed.

You must know that Yang Fan does whatever he wants, but he is not a guy who likes to fool people.

Being able to think of it together with Zaifuzhi, who was praised by his father, shows that his idea is correct.

So Li Chengqian asked eagerly: "Is cement production very difficult? If so, Guhui will send more manpower, as long as Zhongyihou is willing to sell the production technology to Gu."

Yang Fan waved his hand and said: "Your Highness, don't be anxious. In fact, it is okay to give the cement production technology directly to His Highness. Moreover, the cement production technology is very simple and can be completed by building any workshop."

"It's just that it's more than a thousand miles from Chang'an City to Tubo. Not to mention the material resources required, it would be impossible to raise it all with so many laborers."

Hearing this, Li Chengqian was stunned!

yes!

There is a distance of five or six thousand miles from Chang'an City to Luoche City, the original capital of Tubo.

Even walking there would take several years, not to mention the need to dig mountains and dig roads in some places.

It seems that I thought too well.

Suddenly, Li Chengqian, who was originally in high spirits, suddenly became a little decadent.

He finally came up with a good idea, but couldn't implement it at all. How could he not be disappointed?

Li Chengqian's appearance made Yang Fan a little unbearable.

In fact, Li Chengqian's idea is excellent.

If you want to get rich, build roads first, which is common in all eras, but it is a pity that there is a lack of people!

When he mentioned "people", a flash of lightning flashed across Yang Fan's mind, as if he had caught something.

Is Datang really short of people?

actually not.

In addition to growing crops and doing military service, the people of the Tang Dynasty had seven or eight months to do anything else.

If these people and seven or eight months of time are used properly, a huge fortune can definitely be created.

These people don't need too much remuneration. As long as they are given food to eat and a small amount of wages, there will definitely be people rushing to do this kind of work.

Furthermore, even if all these people in the Tang Dynasty could not be utilized, there would still be people like Tubo and Tuyuhun.

There is no need for so many people to herd sheep and cattle. As long as these surplus laborers are given food to eat, they will definitely compete for it.

Thinking of this, Yang Fan said: "Your Highness, in fact, the labor problem is not unsolvable, but there are many problems involved, which may be difficult to deal with."

"Oh? Lord Zhongyi, please tell me. As long as it is feasible, I will do my best." Li Chengqian became hopeful again, with a surprised look on his face.

When Yang Fan expressed his thoughts, everyone was shocked.

The household registration management in the Tang Dynasty was actually very strict. If people traveled across state lines, they had to report and apply to the government.

Once large-scale labor is carried out, there will definitely be a lot of people fleeing. Wouldn't it be chaotic?

Seeing everyone's expressions of disbelief, Yang Fan didn't know what to do.

After all, I have never experienced it at the grassroots level, so I don’t know all these things.

However, Yang Fan's words made Li Chengqian's heart move. He gritted his teeth and sat back and said, "Please rest assured, Marquis Zhongyi. I will strongly advise my father and ask him to agree to this plan. I will pave cement roads to every village in the Tang Dynasty."

."

Yang Fan was also shocked by Li Chengqian's heroic spirit.

Unexpectedly, his own invention of cement gave Li Chengqian the idea of ​​​​connecting every village with cement roads.

However, if every village could be connected to cement roads more than a thousand years earlier, it would have greatly improved the quality of life of the people.

Since Li Chengqian has such a dream, Yang Fan plans to help him again.

So I talked about some of the measures taken by later generations regarding road tolling, segmented contracting...

Although these things were only half-baked, they still made Li Chengqian stunned.

Although the idea is somewhat destructive, it increases the chance of being able to dissuade Li Shimin from implementing village-to-village coverage.

Who made His Majesty Li Er like money?

If building roads can really make money, Li Shimin has no reason to refuse.

After carefully consulting Yang Fan, Li Chengqian couldn't stay any longer and ran back to Chang'an City in a hurry.

Yang Fan twitched the corners of his mouth. Are you busy with something?
