Du Xinyuan continued: "Your Majesty, the people from the Chang'an Chamber of Commerce said that if the court needs it, they are willing to sell 600,000 dan of grain to the Ministry of Revenue at a price that only increases by 1 times."

Now the grain prices in Changcheng City have risen to more than five times that of normal times.

"Did these merchants take the wrong medicine?" Everyone was surprised.

"Buzz" there was another discussion in the hall.

Li Shimin asked: "What are your Ministry of Revenue's plans?"

Du Xinyuan said: "My monk has discussed it and suggested buying it all and then put it in the Chang'an grain market to stabilize prices. With this grain, it can be guaranteed that Chang'an residents will not be worried about food within two months."

"Okay, you guys do it like this." Li Shimin said.

After morning court, Liangyi Hall Study Room.

Li Shimin, Li Chengqian, Changsun Wuji, Fang Xuanling, Li Jing, Xiao Gan, Gao Jingming and Huangfu Rui are listening to Li You's report.

Li You pointed to the huge map hanging on the wall to explain the road traffic situation in the Tang Dynasty.

According to the standards at that time, water transportation in the Tang Dynasty was relatively developed. Among them, the mileage of land transportation roads reached more than 60,000 miles.

There were seven international routes in the Tang Dynasty, namely: from Yingzhou to Lu'an East Road, from Dengzhou to Goryeo and Bohai Road, from Xiazhou to Datong, from Yunzhong Road, from Sujiangcheng to Uighur Road, from Anxi to Western Regions Road, from Annan to Tianzhu Road, and from Guangzhou to Haiyi Road.

The biggest problem with land transportation in the Tang Dynasty was that the road surface was rammed earth pavement, and it would be muddy if it was not hardened.

Li You said: "Father, from the problems that arise on the Tongguan road this time, we can see the backward road traffic in the country and the constraints on the economic development of the Tang Dynasty.

The son and the prince discussed it and in order to improve the land traffic conditions of the Tang Dynasty, it was suggested that the first step was to build seven main roads with Chang'an as the center, namely, connecting Yingzhou, Dengzhou, Xiazhou, Anxi, Sujiangcheng, Annan and Guangzhou.

All these seven trunk lines are laid with cement and are widened on the basis of the original roadbed. These seven trunk lines can be called the Tang Dynasty's expressway."

Now many roads in Chang'an City have been paved with cement, and everyone knows the effect of cement roads. If all these seven main lines are paved with cement roads, the entire traffic conditions of Datang will be greatly improved.

Gao Jingming first asked: "Your Highness, I know you have a solution. How did you solve the money for road construction? Let me explain it in detail."

Now, no matter what suggestions Li You make, no one in the top leaders of the Tang Dynasty questioned it. They believe that Li You must have a proper solution.

Such trust has been obtained through ancient times and the present, and Li You was definitely the first person in the Tang Dynasty.

Li You said: "Building a road is nothing more than two major issues of capital and manpower..."

His suggestion is to establish road construction material factories such as cement factories, sand and gravel factories along the way to ensure the supply of materials for road construction. The recruitment system is adopted and road construction workers are recruited based on prefectures and counties.

All the funds required are raised from private sources, and the income from the material factory belongs to investors.

After the road is completed, the ownership belongs to the investor within the prescribed period, and the government can use it free of charge. Investors can charge a certain fee to the cars and horses that use the road. The Ministry of Revenue can also collect taxes from the investor's income.

Li You explained in detail the various issues in highway construction and management, and kept explaining the questions raised by everyone.

Li Shimin finally completely figured out the problem. He asked: "How confident are you to raise private funds?"

Li You smiled and said, "Father, let me tell you this. As long as it is the imperial edict from the court to raise funds, people will come up and even rush to invest in the stock.

I am dissatisfied with you that the funds for building the road from Chang'an to Luoyang are now impossible to arrange the number of people who have registered here."

Gao Jingming was excited, and the guy accepted the money. He said, "Your Majesty, I agree. If you don't spend a penny on the court, the Ministry of Revenue can collect taxes. I firmly support such a good thing."

Li Jing said: "Your Majesty, with these seven main lines, the efficiency of the Tang army is much higher. I agree."

Changsun Wuji, Xiao Gan, Fang Xuanling and Huangfu Rui all agreed.

Li Shimin likes to do big things. When he heard that the plan was so large, he was immediately excited. He said, "Okay, just do it. After completing these seven main roads, all the roads in the states and counties across the country were covered with cement. Haha, everyone no longer has to walk in mud and water."

Then, he said: "The prince is responsible for this matter, with the assistance of King Li You and Huangfu Rui of Qi."

Li Chengqian, Li You and Huangfu Rui said together: "My son, I obey the order."

Li Shimin was very happy, and he said, "Li You stayed, you can leave first."

After everyone left, Li Shimin smiled and said, "You'er, you did a good job. You solved another big thing for the court."

Li You said: "Father, without your support, my son can do nothing."

Li Shimin smiled and said, "Tell me, how much did you get from it?"

Li You knew that his father was coming to quarrel. He smiled and said, "In the period from Chang'an to Luoyang, Erchen invested a share for his father to build a cement factory. Erchen had the technology to invest, and this scattered one is not easy to calculate.

Do you think this is OK? This project is worth 50,000 yuan a month.”

Li Shimin smiled and said, "Okay, what big projects will be there next..."

The Palace of King Qi.

He, Cheng Yaojin and others, as well as the Chang'an Chamber of Commerce, divided up one of the most important sections of the Tang Dynasty - the road from Chang'an to Luoyang and the cement factory along the way.

Li You has invested in technology, and there are so many cement factories across the country, but he has made a lot of money on this project.

Compared to Li You and Li Chengqian making a fortune, Li Ke was in trouble.

That morning, Tai Chi Hall.

Li Ke said: "Father, my son has already discussed with the Ministry of Works and will prepare for repairing the Yongtong Channel in the near future. When Daozhu Li heard that there was a suitable weather condition in the upper reaches of the Ba River, he immediately started the emergency repair of the Yongtong Channel.

The Ministry of Works has limited staff, so I asked my father to give in to the local prefectures and counties to recruit people from local prefectures and counties.”

"How many people need to be recruited?" Li Shimin asked.

"The total number of people repairing Yongtong Canal is 7,500." Li Ke said.

"Your Majesty, I am against recruiting people." Wei Zheng said: "The court has just implemented a policy of pacifying the people and calmly..."

"I'm going to discuss it."

"I object."

...

After morning court, the East Palace.

"Haha, fifth brother, Li Ke really can't do the canal repair. His suggestion was criticized by the ministers and his father was also dissatisfied with him.
Chapter completed!
