"How much is appropriate, don't be so anxious about this question, wait until the road is repaired.

As for whether the imperial court will agree, why would the imperial court not agree? The whole road does not need the imperial court to invest a copper plate, but the imperial court has one more road that can respond quickly, and the military significance of this road is greater than that of civilian use.

Just imagine, if the emperor is now in the palace of Luoyang, the eastern capital, and something big suddenly happens in the imperial capital, can the emperor quickly return to Chang'an through this cement road to deal with emergencies.

After repairing the cement road from Chang'an to Luoyang, the road from Chang'an to various states and counties can be repaired cement road, and businessmen can benefit from this, and the people can also earn a fairly good salary because of their participation in road repair.

The imperial court not only strengthened its rule over various places, but also was able to greatly prosper the economy and increase taxes because of the construction of roads. Li Zhonghua said very confidently.

"Then if not many people are willing to pay for the cement road, and would rather take the previous official road, then we won't even be able to recover the cost at that time, wouldn't it be a big loss, and the concubine still feels that the risk of building the cement road is really too big." Wu Zetian shook his head and said hesitantly.

Wu Zetian's gaze, or rather, the people of this era, can't see so long-term, in fact, it is very normal, Li Zhonghua didn't think it was so strange.

Although Wu Zetian has been in charge of the family's business for ten years, it stands to reason that he should be very mature, but the business that Li Zhonghua handed over to her to manage is simply not too good, what risks are there to worry about?

Basically, the business is found by herself, and she doesn't need to think of a way to sell products, and what she manages the most is the personnel arrangement in production, the sales management personnel such as the shopkeeper of each store, and the settlement of sub-accounts in cooperation with each company.

The investment aspect is also very simple, it is nothing more than where to open an additional branch, and when the supply of products exceeds demand, increase production and recruit more workers.

Those investments can be said to have no risk at all, as long as you invest in them, you can see the return immediately.

Investing in concrete roads is something that has never been done before, and no one has done it.

Don't say that it is an investment in building a cement road, it is an ordinary road, and it has never been repaired with private investment, even if there are well-meaning people who pay to repair the road, it is only a short road.

As for collecting tolls, it is something that has never happened since ancient times, and those bandits and bandits are blocking the road and robbing others.

Li Zhonghua could only patiently explain some advanced concepts to Wu Zetian.

"Merchants take the principle of seeking maximum benefits, if they transport a batch of goods from Luoyang to Chang'an for sale, and take the ordinary official road, they will not only have to endure bumps along the way, but also spend ten days on the road.

And take the cement road we built, the carriage that transports goods, it will run very fast, there is no need to worry at all, after the weather suddenly rains, the wheels will sink into the mud puddle, from Luoyang to Chang'an, it only takes three days, then you say that the businessman is willing to pay some money to take the cement road, or take the free official road. Li Zhonghua asked.

"You can pull the goods from Luoyang to Chang'an in three days, then you must be willing to pay some money and take the cement road, and you can go to Chang'an one day earlier, and you can also sell the goods one day earlier." Wu Zetian said without hesitation.

"Isn't that right? Then you still need to worry, no one wants to take the toll concrete road? Li Zhonghua breathed a long sigh of relief and said with a smile.

Wu Zetian is really a little stubborn! It took a lot of saliva to persuade her.

"If you are afraid of taking too many risks, you can also attract investment, I believe that many people see the effect of cement, they will not introduce investment, and let's build this one, from Chang'an in the west to Luoyang in the east." Li Zhonghua made another suggestion.

For this cement road, Li Zhonghua was not worried at all at that time, and the imperial court would refuse to build the road.

Today's imperial capital Chang'an City is facing a very important problem, that is, the food problem.

From the geographical point of view, Qinchuan, which is 800 miles around Chang'an City, can basically provide residents with daily food needs.

But in fact, because Chang'an City is concentrated with wealthy nobles from all over the country, as well as merchants from Eurasian countries who come to do business, the food rations consumed by millions of foreigners are difficult to measure.

Most of the area in Longxi is the territory of the Imperial Horse Supervisor, which is mainly used by the imperial court to raise horses, and is not used for farming.

The agricultural economy in the Guanzhong region was originally quite developed, so from the Western Zhou Dynasty to the Tang Dynasty, Chang'an was repeatedly the place where the capital was built.

However, since the Eastern Han Dynasty, the importance of the agricultural economy in Guanzhong has been declining in the whole country, and the limited land area suitable for agriculture in Guanzhong has made food supply a major problem for Chang'an as the population multiplies and the ruling institutions swell.

There are only two ways to solve this problem, one is to revitalize production in the Guanzhong area, and the other is to transport more grain from Kanto and Jiangnan to Guanzhong.

The revitalization of production in the Guanzhong region is faced with many problems, one is that the natural conditions in Guanzhong during the Tang Dynasty are no longer comparable to those in the Qin and Han dynasties. After Guanzhong suffered several tragic damages, especially during the period of the Sixteen Kingdoms of the Eastern Jin Dynasty and the war at the end of the Sui Dynasty, the soil and water were seriously eroded, the loess was desertified, the sediment content of the Jing, Wei, Beiluo and other rivers increased greatly, and the irrigation role was reduced day by day.

For example, in the early Tang Dynasty, the irrigation capacity of Zhengguo Canal was less than a quarter of that of the Qin and Han dynasties, and the second was that the growing population made the limited arable land lose its load, that is, the so-called "narrow land and dense people, and cultivation is not rich".

At this time, Chang'an has developed very prosperously, and a large number of people live in Chang'an City and outside the city, as many as 1.5 million people, more than one-tenth of the population of the entire Tang Dynasty.

Guanzhong is also the most populated northern hinterland, although the Guanzhong area was known as fertile at that time, but "what was produced was not enough for the Beijing Division".

Third, there are many princes and magnates in the Guanzhong area, who compete to build stone mills next to the irrigation channels, which consumes water and affects the efficiency of water conservancy and irrigation. The irrigation area of Zhengbai Canal has dropped from more than 40,000 hectares to more than 10,000 hectares.

The first way did not work, so we had to rely on the second way to solve the food crisis in Guanzhong, but it was not easy.

Transporting grain from Kanto to Chang'an is not only a long way, but also a section of the Yellow River in Sanmenxia is narrow, the water is turbulent, and there are many reefs underwater, making it extremely difficult to sail.

The price paid for the transportation is very high, but the transportation volume is very limited.

In order to overcome the three natural hazards as much as possible, the Sui and Tang governments have carried out improvement plans, but the results are not ideal.

In the fourth year of the emperor, Emperor Wen of Sui adopted the method of "transporting grain from Xiaoping to Shaanxi by land", and then "returning from the river to Weichuan", and then reaching the Jingshi.

In this way, although the Sanmen natural danger is bypassed, the land transportation cost is very large, and the land route from Xiaoping to Shaanzhou must pass through the steep Kun and Han valleys, and the risk is also very large.

In June of the fifteenth year of the emperor's reign, Emperor Wen was forced to resume water transportation and "chisel the bottom pillar", but still failed to increase the volume of water transportation.

If there is a cement road that can quickly transport grain from Luoyang to Chang'an, Li Shimin will wake up with a smile in his dreams.

However, in the long run, it is still the most cost-effective way to take water transportation, and after crossing Sanmenxia, taking Weishui into Chang'an.

In recent years, the price of grain in Chang'an has continued to rise, because the population growth rate is too fast, can the grain transported from the southern trough not be expensive after being transported to Chang'an? Although it is an exaggeration to use bucket money to transport bucket rice, it is not unreasonable.

The main consumption of sake brewing is food, so the cost is also increasing year by year.

None of this is a problem when it comes to making wine in Jinzhou, Liaodong, which has a lot of land where grain can be grown.

Li Zhonghua suddenly thought of another thing, which was very helpful in solving the difficult things of Cao Yun.

According to historical records, it was not until the twenty-second year of Xuanzong of the Tang Dynasty, that is, more than 90 years later, that Pei Yaoqing adopted the method of sectional transfer to transport grain, and this situation improved.

Pei Yaoqing set up warehouses at the confluence of the Yellow River, the canal and the Weishui and the east and west of Sanmenxia, and the grain was first imported into the east warehouse, and then the mountain road was opened for 80 miles, and it was transported to the west warehouse by land, and finally transported to Guanzhong.

In this way, the boat travel date is shortened, and the transportation efficiency is improved. History, for three consecutive years, "Cao 7 million stones, 300,000 yuan of provincial land transportation commission". In three years, it will save 300,000 yuan, and the high cost of transportation can be imagined. The saying of "using money to transport rice" is true.

Before, the problem of food was not prominent, and Li Zhonghua didn't care about these things, but now it's different, once there is a year of famine, let alone using grain to make wine, I'm afraid that people in Chang'an City will starve to death.

Although because of the appearance of Li Zhonghua, many people are not short of money in their hands, but once there is a disaster year, the grain in the south cannot be transported to Chang'an through Cao Yun in time, and the problem is very big.

In the early spring of each year, a large amount of rice from the south of the Yangtze River will be transported to Chang'an by means of water transportation. The shallow flow of Weishui and the deep sand, the danger of the Yellow River, and the lack of water in the Cao River will affect the transshipment of grain.

Therefore, the grain is actually the most unstable, and the loss on the road is also very huge.

Especially when crossing Sanmenxia, there is a section of the river with turbulent current, many bends, and many dark cokes, the slightest carelessness, that is, the ship is wrecked and people die, and the grain of the whole boat sinks in the river, and it is destroyed in one fell swoop.

Therefore, later I had to dock at Sanmenxia, switch to land transportation, bypass the Sanmenxia River section, reload the ship, and transport it to Chang'an.

In this way, it not only consumes time, but also greatly increases the cost of transportation.
