After returning from Li Ying, Li Chongjiu returned to Ganyang Palace to handle government affairs.

On the side of the Secretariat, Yu Shinan and Zhang Xuansu came together.

"Jiang Shan asked Xu Yuanlang to join forces. Xu Yichou and his son were not dead. Let them serve the people." Li Chongjiu looked at the memorial and frowned, "I issued an order to ask the Xu family and his son to be headed by each other, but he actually disobeyed my will."

Yu Shinan said: "Your Majesty, there is a reason for the incident. Jiang Shanhe entered the city and pretended to surrender..."

Yu Shinan's plan to Xu Shiji, Wang Bo and Jiang Shanhe talked about it. Li Chongjiu then realized it and said: "It turns out that there are still these twists and turns. If it weren't for this, it wouldn't be possible to take Yanzhou so quickly. Jiang Shanhe promised Xu Yuanlang and his son that he would not die. Although he was making his own decisions, it was understandable."

Zhang Xuansu said: "Your Majesty, after hearing that Xu Yuanlang was captured, he scolded His Majesty in front of the prison guards all day and night for being untrustful and shameless."

Li Chongjiu heard this and said, "What happened?"

Zhang Xuansu said: "Your Majesty, Xu Yuanlang is the way to seek death, and this person cannot be let go."

"But General Jiang has already agreed to him. Aren't we going to treason?" Yu Shinan opposed.

Zhang Xuansu said: "It was Jiang Shanhe who agreed, but Your Majesty did not give him this power. Just take it back. Then I will give Jiang Shanhe some compensation."

Yu Shinandao: "But this matter is related to the national system and spread it."

Li Chongjiu said: "You don't have to argue anymore. I have already made a point of view. What I am concerned about now is how have I done the embargo on Guanzhong in the past two months?"

Zhang Xuansu said: "Report to Your Majesty, I am about to report to you that the waterways and land roads in Luoyang from Guanzhong have been set up and guarded by soldiers. Passing vendors are strictly investigated. According to Your Majesty's previous instructions, any food and salt involved will be subject to a heavy tax of ten times."

Li Chongjiu said: "This matter is not easy to handle. Although we set up checkpoints, there are also profit-seeking people. Smuggling them to Guanzhong, so those who have to deal with such people should be dealt with more severely."

Zhang Xuansu said: "Your Majesty, the meritorious minister will order the soldiers to strictly supervise this matter."

Li Chongjiu said: "I will feel much more at ease when Zhang Aiqing does things. So in the past two months of embargo, the price of Guanzhong grain will fluctuate."

Zhang Xuansu said: "Report to Your Majesty. The climate in Guanzhong this year is pretty good. Although the weather is not good, it is still a normal year."

"A normal year, what about last year?" Li Chongjiu asked with concern.

“It’s also good.”

Zhang Xuansu said this and smiled and said, "But even if it is good, the grain rice in Guanzhong is not enough in normal years. Since the founding of the Sui Dynasty, Guanzhong grain rice has to be transported to Guanzhong by the Jianghuai rice, and at least one million stones per year. In the past, when grain was transported, the grain ships were directly to Luoyang, and went north through Sanmenxia, ​​and then took land through Tongguan Road, and then transported to Chang'an by boat through Weishui. Now the Yellow River waterway is blocked, where is the grain ship on the Yellow River going west."

Li Chongjiu heard this and asked, "Didn't it mean that it's difficult to sail in Sanmenxia?"

Zhang Xuansu said: "Your Majesty is right. In the past, the Yellow River passed through Sanmenxia and was extremely difficult to sail against the current. Therefore, all dynasties have been drilled on the rocks along the north bank of the river, and then inserted cross-wood into the holes and laid wooden boards as fiber-pulling plank roads to let the boat pull up the current. But even so, Sanmenxia still destroyed the ship from time to time. By the seventh year of Daye, the mountain collapsed, the Yan River flowed against the current for dozens of miles, and the Yellow River flooded more than 30 counties downstream. Therefore, the waterway of Sanmenxia was even more difficult to travel, but there were always people who were greedy for luck and sailed from then on."

Li Chongjiu said: "The waterway is not smooth, it seems that there is only one way by land."

Zhang Xuansu said: "That's right, Your Majesty is now capturing Luoyang. Another ban is issued. No matter whether the Jianghuai merchant ships or the land merchant gangs cannot enter Guanzhong west. Therefore, although the summer grain in Guanzhong is about to be harvested, the price of grain has risen instead."

Li Chongjiu said: "It's still like this in the good times. It depends on how Li Yuan can survive the disaster. Even if I don't attack Chang'an and block Luoyang, I can force Li Yuan to run out of food within a few years. Of course, unless Li Yuan moves the capital, he will lose the support of the Guanlong clan and die faster. So can Li Tang have a way to deal with it now?"

Zhang Xuansu said: "According to the news we have come from the Li Tang Dynasty, Li Yuan has attached great importance to the rise in Chang'an's grain prices. He is now preparing for the future, and even lists his important matters as the attack on Xiao Xian this year."

Li Chongji smiled slightly when he heard this. Now Li Tang and Zhao Kingdom are facing difficulties. Li Yuan faces a crisis of insufficient grain and rice in Guanzhong, while Li Chongji Canal is blocked, making it difficult for Luoyang and Youjing ship transport. However, Li Chongji has ordered Zhou Bo and He Chou to take charge of this matter. It is expected that the Yongji Canal can be cleared within this year.

And what about Li Tang? Although there was a bumper harvest of food and grass this year, there were many major and minor disasters in Guanzhong, and Li Yuan could not be so lucky every year. Last year, Li Yuan might have survived this year. If the Guanzhong famine next year and Li Yuan would be too busy to take care of himself, the opportunity for Zhao State will come.

So now for Li Chongjiu, it takes time.

"Li Yuan is a visionary person," Li Chongjiu asked immediately, "Then the Li Tang court has discussed what kind of response measures? I don't believe they will sit and wait for death."

Zhang Xuansu said: "Did Li Tang come up with two solutions?"

"Two ways?" Yu Shinan said with a smile, "I really didn't expect that if there was a way, Emperor Wu wouldn't have to move the capital to Luoyang."

Yu Shinan looked disapproving, and Li Chongjiu said, "Let me tell you, maybe there is something impressive? In my opinion, the fertile land in Guanzhong has been cultivated to the extreme. The solution to Li Tang's current solution is to raise grain from other places."

Zhang Xuansu said: "Your Majesty really predicts things like a god. One of the solutions to Li Tang is to rebuild the Baoxie Road, and the grain and grass will be connected to the Baoxie Road through land to Baoshui, and from the Xiangxie River to Weihai, then the canal ship will be carried."

You should know that the ancient roads leading to Guanzhong from Hanzhong include Baoxie Road, Chencang Road, Tangluo Road and Ziwu Road. Although Baoxie Road is narrow and dangerous, it is relatively shorter than the other three roads and is also the most important passage from Hanzhong to Guanzhong.

Li Chongjiu smiled and said, "Did Li Yuan want to transport grain from Sichuan and Sichuan? I heard that Zhuge Liang went to Qishan seven times and repeatedly withdrew his troops because of the food exhaustion. If Baoxie Road could really transport grain, Li Yuan would be better than Zhuge Wuhou."

Zhang Xuansu and Yu Shinan smiled when they heard Li Chongjiu's joke.

This is true. As we all know, it is well known that the states in the world are about prosperity. Compared with Chang'an, Sichuan and Shu are close to each other, while Jiang and Huai are far away. If you can transport grain from Sichuan and Shu to Guanzhong and solve the problem of shortage of food, it is of course the best.

However, the dream is not reality after all, and the difficulty of Shu Road is daunting. It takes too much effort to transport grain across the Qinling Mountains to Guanzhong.

Zhang Xuansu said: "That was the case when the Li Tang court discussed that it was digging a road from Shangzhou to cross the Qinling Mountains to Sichuan and Shu. However, this strategy was just a drop in the bucket. Even if the grain from Sichuan and Shu was transported to Guanzhong, the grain rice was not afforded by the princes and ministers."

"What about the second solution?" Li Chongjiu asked.

"The second way to discuss with the Li Tang dynasty is to cultivate farms in the Hedong area and irrigate the Yellow River water. If it is successful, it can open thousands of hectares of fertile land and collect more than hundreds of thousands of stones."

Li Chongjiu frowned and said, "Is this feasible for farming in Hedong?"

Yu Shinan stepped forward and walked forward: "Your Majesty has a precedent for this matter. During the Han Dynasty, the grain transportation was mostly damaged due to the limitations of the pillars, so a minister suggested that he could rush through the canals to irrigate the Pi family, and Fenyin, which is today's Fenyin and Puban. The ministers said that after military farming and getting the grain, they could save thousands of miles of grain transportation from Wei to Guanzhong. However, the emperor sent tens of thousands of soldiers to make the canal fields, but the grains were not collected."

"It's not so easy to irrigate canals. Your Majesty can rest assured. If Li Yuan wants to farm here, he will just repeat the same mistake."

Zhang Xuansu said: "But now Li Yuan really attaches great importance to the grain in Hedong. In order to ensure the bumper yield of grain in Hedong, Li Yuan recently sent the chief commander of Shaanxi Province Yu Yun to station troops in Lingzhou to prepare for the Turks to build grass valleys. Li Yuan also ordered the establishment of a navy in the Yellow River in Lingzhou, to go to Jiangnan to recruit shipmakers to build ships, and set up a six-city water transport box governor of grain ships."

Yu Shinandao: "Although Li Yuan hoarded grain in Hedong, it was easier than transporting grain from Baoxi Road, but the grain in Hedong must be supplied to Guanzhong and Lingzhou. How can he have spare energy for the soldiers and horses in Hexi?"

Zhang Xuansu and Yu Shinan both believed that Hedong fertile fields were limited. If Hedong fertile fields could be really supplied to Guanzhong, then there would be no need to find a way to transport grain from the Jianghuai Dynasty in all dynasties.

Since the Han Dynasty, Guanzhong's population has always been in the world. From the Han Dynasty, Wei and Sui Dynasty, they have been moved to Gaozi and rich people, and heroes have enriched Guanzhong. However, Guanzhong has a large population, but since the Qin and Han Dynasties, the land and soil have not increased due to long-term severe drought and flooding, and the grain production of Qinchuan in the 800-mile area has not increased.

Now that the population is increasing and the food decreases have formed a dilemma in Guanzhong. Although Li Tang established the capital of Guanzhong, it has its advantages, but it also has its disadvantages. This is why, from Emperor Gaozong to Wu Zetian to Emperor Xuanzong, he always wanted to move the capital to Luoyang. However, except for Wu Zetian, the plan for other people to move the capital was under the strong opposition of the Guanlong clans, but it was not successful.

During the reign of Emperor Xuanzong, Emperor Xuanzong of Tang appointed Pei Yaoqing as prime minister. Pei Yaoqing proposed to adopt the transfer method, and first dismiss the land transport in Shaanxi, and set up the river estuary of the Cang River to transport the river estuary of the Jiangnan canal to transport the river estuary; import grain into the warehouse and return to the south of the Yangtze River. The court then hired boats to enter Luoyang. Later, granaries were set up in the east and west of Sanmenxia, ​​and the canal from Luoyang was imported into the East Cang, and then imported into the West Cang by land transport, and then imported into Chang'an by boat, thus avoiding the water danger of Sanmen.

Pei Yaoqing's method is to transfer transportation step by step, and a special person is responsible for land transportation and canal transportation, which is only slightly relieved.
