Eight hundred miles west of Dali.

The Sui people called the Hetao of Fengzhou Beach, Jiuyuan City of Wuyuan County.

The northernmost end of the straight road built by the Qin Dynasty was here, and the Zhao State built a military town here to defend against the Xiongnu during the Warring States Period, and the Qin Dynasty established Wuyuan County after the unification of the world.

Li Shuliang came back from his camp tour and found that Yun Dingxing was already waiting in front of the yamen, waiting for him, standing there very respectfully. He jumped off the horse and stepped forward with a smile to hold Yun Dingxing's arm, "Yun Hou came so early, why didn't he go in first?" ”

Yun Dingxing's expression was humble, "If the king of the county is not here, how dare he enter first." ”

"Yunhou, why do we have to talk about these false courtesies between us." Li Shuliang said and pulled Yun Dingxing into the government, he was named the king of Changping County, and he was the eldest son of Li Yuan's uncle Li Yi. Lingwu defeated Liang Shidu first, and then Jiuyuan City forced Yun Dingxing to surrender again.

Chai Shao took 80,000 horses and horses to continue to meet the division of Jieli, while Li Shuliang led 20,000 troops to stay in Jiuyuan, he was responsible for the military and political affairs of the entire Hetao area, and was responsible for transporting ordnance, grain and grass for Chai Shao.

For Yun Dingxing, the guy at both ends of the first rat, Li Yuan was very annoyed. Before, he waited left and right and refused to return, and only after getting enough officials did he annex, but it didn't take long for him to fall to Luo Cheng again. This time the army came, Yun Dingxing surrendered to Tang again, and Li Yuan gave that the situation was not very good now.

didn't dare to punish him severely, but just demoted the title of county prince who originally sealed him to a marquis, and demoted him to the governor of Fengzhou, as the deputy of Li Shuliang, the governor of Fengzhou.

Li Shuliang pulled Yun Dingxing into the yamen and sat down in his public house.

"Yunhou, now that the army of Chai and Ma Tong is attacking Hedong, the logistics and grain all depend on us, but I have visited and inspected below these days, and the situation is not optimistic."

Fengzhou Beach is a very good place, there is a big mountain barrier in the north of the sand, and there is the Yellow River water system, so that the water and grass here are abundant, and from the Warring States period Zhao State control here, the Han family has also been here to implement farming and reclamation, there is a good agricultural foundation, there are even Qin and Han dynasties and other irrigation channels developed in the tuntian, but since the Sui Rebellion, here has also suffered a lot of impact.

Yun Dingxing was once the father of Yang Yong, the deposed prince of the Sui Dynasty, and was a person who was very good at flattery. After Yang Yong was deposed, he personally poisoned all of Yang Yong's sons, including several of his nephews. relied on bribing Yu Wenshu and successfully threw himself to Yang Guang's side.

As Yang Yong's father-in-law, Yun Dingxing actually mixed well in the Daye Dynasty, served as a general, and later became the festival envoy of the Hetao.

Although he failed to raise troops to fight for the world during the Sui Rebellion, he also had tens of thousands of horses in his hands to divide the northern side of the country.

"King of the county, after all, the population of the Hetao area is still smaller, and the feudal and Han clans here are mixed, and the folk customs are more vigorous."

After all, he has been here for several years, so Yun Dingxing can be regarded as the head snake of the Hetao.

He slowly explained the situation here to Li Shuliang, far away in the Warring States Period, after the Hufu cavalry and archery reform, the Zhao army swept through the northern Jin Dynasty, opened up the territory, and drove the Hu people of Lin Hu and Lou Fu to the south of the later Hetao and Shuofang, facing them across the Yellow River. He also drove the Huns to the area north of the Wula Mountains and confronted them across the mountain.

At that time, the Zhao State was really arrogant, they established Yunzhong County on the land of Inner Mongolia they occupied, and in order to prevent the counterattack of the Xiongnu in Shanbei against Yunzhong County, they built the Great Wall of Zhao along the Wula Mountain.

At the same time, in the mountain pass that communicates the north of the mountain, the castle of the garrison and the defense of the material is slender, the largest of which is the Hademen ditch of the later generation, Zhao State built a large castle in the south of this mountain pass, that is, Jiuyuan City, and stationed heavy troops in the city, making it the military town of Zhao State in its northwest.

Since then, in all dynasties, this place is basically a place for the Han family.

During the Qin Dynasty, he once directly repaired the Qin Straight Road all the way to Jiuyuan City.

Qin Shi Huang sent Meng Tian to lead an army of 300,000 to attack the Xiongnu, and after recovering the Hetao, he built 34 county towns along the Yellow River, and set up a new county in this vast Hetao area, named Wuyuan County, which was no longer subordinate to Yunzhong County in the east, which also became one of the 36 counties of Qin.

However, it is precisely because it is too close to the border area, especially the unique terrain of the Hetao area, where water and grass are abundant, but to the south is the vast Ordos Loess Plateau, which makes the Hetao area especially like a Han enclave, when the grassland tribes are strong, they tend to occupy it, and even repeatedly invade.

"I also know that after the establishment of the Sui Dynasty, he recovered the land of Hetao, set up Fengzhou, Lingzhou, etc., and later handed over the land of Dingxiang in the east to Qimin Khan." Li Shuliang needed Yun Dingxing's cooperation and needed Fengzhou's money and grain to supply Chai Shao's soldiers and horses.

In the Hetao area of Fengzhou, the land on the north bank of the Yellow River is the richest, but the south bank of the Yellow River is a continuous desert, although there are several ancient roads to pass through Zhongzhong, Shuofang and other places, but the road is difficult to travel, and the grain and grass are more difficult to transport.

Li Shuliang's plan was to build a ship in Fengzhou, and then rely on the relatively gentle water surface of this section of the Hetao to use ships to transport grain and grass to the mouth of the Jinhe River on the other side of the Shengzhou River, and then switch to land transportation by vehicles and horses. Even with a fleet, in the future, the fleet can be directly driven to Lingzhou, from where the grain and grass of Guan and Long can be transferred.

But these all require the cooperation of Yun Dingxing.

After all, Yun Dingxing has been here for a few years, and he has brought tens of thousands of people to join him, and he still has a great appeal to these generals, not to mention that the local wealthy and powerful families have a good relationship with him.

He, Li Shuliang, crossed the river dragon alone, and if he wanted to do good things, he had to rely on him.

When Chai Shao left, he gave Li Shuliang two tasks.

The first is to reorganize Yun Dingxing's soldiers and horses, and reorganize them all into the 20,000 Tang army led by him, and mix them into four armies, with a total of 50,000 horses and horses, and 12,000 troops each.

The second thing was to raise grain and grass in the Hetao area to build ordnance transfer for the Eastern Expeditionary Army.

The reorganization of soldiers and horses has almost been completed, and Yun Dingxing is still very cooperative.

Of the 50,000 soldiers and horses, Li Shuliang transferred one army to Lingwu City, Lingzhou, and another army to Guozihe, Shengzhou, which returned to the Tang Dynasty, and then left two armies, one army in Fengzhou, and the other army in Huyan Valley in the middle of the Hetao.

Everything went smoothly.

Only the matter of requisitioning and transporting grain has encountered some trouble.

"Temporary shipbuilding takes time, and craftsmen are also needed, but I am afraid that we will not be able to catch up, but there are hundreds of miles of the Yellow River here in Fengzhou, so there are many fishermen and fishing boats here, and the lower officials can immediately send people to recruit these fishermen and fishing boats, so that they can assist in transporting food and ordnance to the east, and at the same time, they will also recruit craftsmen and people, so that they can start cutting wood and building ships."

Li Shuliang was very satisfied with his reaction.

"In this way, there will be Lao Yunhou, and when the firewood and horses invade Taiyuan, there will be no need for us to work hard to transport grain and grass from here, and he can supply it on the spot."

Li Shuliang said with a smile, "The merit of the Marquis of Yun, a certain table will be played in the imperial court, and after this battle, I believe that Your Majesty will definitely summon you back to Beijing and confer on you the position of prince and princess." ”
