Li Wenyuan personally led two legions out of Jiayu Pass and marched in the direction of Yumen Pass, the first stop since the Western Expedition. The 30,000 men of the two legions on this trip, plus countless people in charge of logistics, made Li Liang rebel, and the originally somewhat desolate official road suddenly became lively.

Li Wenyuan did not deliberately cover up this march, but made a big fanfare, and even held a grand ceremony to sacrifice the flag in Jiayuguan, which also made Li Liang's side know early that Li Wenyuan had led his troops to the battle. Since Li Liang's rebellion, although he is no longer bound by the imperial court, his life has been very unsatisfactory. Not to mention that the eight counties of the Western Regions that he had planned for a long time were cut off in half for no reason, and they were still the four richest counties. What made him even more unacceptable was that the wealth he had worked so hard to accumulate was intercepted by Li Wenyuan. When he first arrived in Igo County, he didn't even have enough pay to pay his soldiers. Only then did he have to take refuge with the Turks, accept the canonization of the Turks, and receive financial assistance from the Turks, so that his army did not mutiny.

Now that he has conquered the end of the county and Shanshan county, the finances and soldiers, which were originally a little tight, have improved slightly. The wasteland in the two counties has also been reclaimed for military use after the autumn harvest of grain. But who knew that at this time, the news that Li Wenyuan led his troops to go out came from Jiayuguan. Hearing the news, Li Liang was so angry that he scolded him. But even if it is, it won't help.

At this time, Li Wenyuan's troops had already pointed to the Yumen Pass, a checkpoint to the east, and the land further west of the Yumen Pass was one of the most important sources of military rations for Li Liang this year.

Therefore, Li Liang immediately sent his Turkic cavalry to harass Li Wenyuan's army and contain their marching speed. On his side, he could mobilize a large army and go to Yumen Pass, and he must keep Li Wenyuan's army out of Dunhuang County, so as to ensure that his military rations would not be lost.

In addition, although he was canonized as a khan by the Turks, several cavalry units supported by the Turks did not listen to the announcement. Ben did not accept Li Liang's command, but because of the traditional concept, he would not refuse any orders of his Great Khan. Moreover, on weekdays, these cavalry units are in a lot of trouble, and this time Li Liang transferred them to the front line, first, in the hope of delaying Li Wenyuan's marching speed. Second, he also wanted to borrow Li Wenyuan's army to consume these Turkic cavalry. After all, in his opinion, in addition to the elite army led by those famous generals, the rest of the army in the Central Plains were a rabble, and it was difficult to stop the attack of the Turkic cavalry.

Moreover, he had also heard about Li Wenyuan's change in the army's establishment, and he was quite disdainful in his heart. Originally, the basis for the Central Plains army to compete with the Turkic cavalry was either sharper cavalry, or a large number of kills and wounds of the Turkic cavalry with bows and arrows with the help of military vehicles, so that the Turks could not bear the casualties of the charge and then retreated on their own before pursuing. Li Wenyuan, on the other hand, is not only the number of soldiers in each team reduced. It also abandoned the traditional military vehicle and switched to the use of a mixed infantry and cavalry formation.

Li Liang couldn't help but laugh in his heart, although Li Wenyuan still has some ability to pacify the locality, he really doesn't know anything about military affairs. If it is attacked by the cavalry of the Turks this time, after heavy losses, it may retreat to Jiayuguan. On the other hand, as long as you survive the winter of this year, you will be able to raise more troops when you have surplus food in your hands in the coming year. At that time, he could break free from the control of the Turks and become a king in the true sense of the word. It can even fake the hands of the Turks and have the ability to win the Central Plains.

Li Liang's mind had even thought of the scene of accepting the worship of his ministers after ascending the throne, and his heart couldn't help but be hot, and he gave the pair of Turkic cavalry an order to speed up, telling them to drag Li Wenyuan's army on the way no matter what, and not let them capture Yumen Pass before their army arrived.

It must be said that the Turks are an extremely warlike and warlike people. As the army sent by the Western Turkic Khan to assist Li Liang in attacking the Western Regions, they were very disdainful of Li Rail, a small Khan king who was canonized by the Great Khan, and who was also a Khan of Han blood. But I heard that there was a battle ahead, and the opponent was still the Han army, which had always been regarded as a two-legged sheep. It was to let go of the disdain for Li Liang in his heart, and after receiving the military order, he set off from Dunhuang County in the starry night. Cross the Shule River and travel east along the foothills of the North Mountain.

Li Wenyuan's side naturally got the news, at this time, the Udrud's cavalry corps brought out by himself was sent to the front as the vanguard of the entire army, and this fourth corps, as the only all-cavalry corps under Li Wenyuan, naturally would not be dragged down by the infantry during the march and lost its most valuable mobility advantage. Therefore, Li Wenyuan was placed in front of him, and as the vanguard, he went to strangle the scouts of Li Rail's army who were watching the intelligence of the army.

When Li Wenyuan learned that the Turkic cavalry had passed through the Yinwa Gorge in Beishan and continued to march towards Wutong County, he faced Zhang Juntai on the side and said: "I can't go any further, so I order the army to immediately turn north and camp in Huahai County at the foot of the ancient Great Wall, ready to deal with that group of Turkic cavalry." ”

Zhang Juntai nodded in agreement, and the current 15,000 people of the First Legion, and the people in charge of logistics, went directly to the north and entered Huahai County. The officers and soldiers of the first army set up a large camp around Huahai County relying on the remains of the ancient Great Wall, this time facing the Turkic cavalry, Zhang Juntai did not dare to hold it up, and hurriedly commanded his subordinates to build all the fortifications against the cavalry attack camp one by one, and then began to place the people in Huahai County, and the army was stationed in the military camp under the ancient Great Wall.

Li Wenyuan saw that the soldiers under him were arranging defenses in an orderly manner, so he nodded and stopped caring about camping. He turned to the remains of the ancient Great Wall on which the barracks rested. When the Central Plains Dynasty was in decline, it was unable to maintain the Great Wall built during the Han Dynasty. The Great Wall has collapsed in many sections under the wind and sand, and the section of the city wall on which the army camp relies is only left with broken bricks and tiles and the rammed earth layer in it, and Huahai County, not far away, only has an earthen wall as a defense. However, the Turkic cavalry came from afar and was unable to attack. This earthen wall could also be used as a backing for fortifications.

Thinking of the generous gift he prepared for the Turkic cavalry, Li Wenyuan was also very curious about how much shock this gift could cause to the Turks.
