As early as when the zahu cavalry in Sheyan left the city, Xu Huang had already got the news from the golden carving. He was very happy to see that there were only a few thousand people on the other side. Although he was a new investor, Huangfu Chaobo tried his best to get rid of the public opinions and let him take the post of commander-in-chief. For this, Xu Huang Huang had no other feeling in his heart except for the death of his confidant He has an idea.

Originally, he was afraid that the foreign troops of Sheyan city would escape, so after sending out troops, he ordered Yuanrong crossbow soldiers to be the vanguard, while the rest of the troops followed him two miles behind him. Now, seeing that the enemy did not escape, he took the initiative to go out of the city to fight. He immediately ordered Liu Bao and the two cavalry of huyandu to bypass Yuanrong crossbow soldiers and encircle the two wings.

The battle lasted only two quarters of an hour. After a round of crossbows and arrows of Yuanrong crossbow soldiers, thousands of miscellaneous Hu cavalry had lost nearly a thousand people. Then, after the two wings of 20000 cavalry gathered around, the rest of the cavalry only persisted for a moment, and most of them were wiped out by the army. Less than 3000 cavalry left dismounted one after another to surrender when there was no hope of escape.

Later, Xu Huang ordered that the soldiers should be left here to clean the battlefield. He led 30000 cavalry to the city of Sheyan.

Facing more cavalry than himself, the people in Sheyan city were all captured without more resistance. Later, Xu Huang ordered all the generals above the centurion in the surrounding tribes to be selected, ready to leave with the army and send them to Fushi city for custody.

After a day's rest in Sheyan, the rest of the army set out again and headed for the eastern city of Kucha.

Two days later, when Xu Huang led the rest of the army and three thousand miscellaneous Hu cavalry prisoners to Qiuci City, Huangfu Chaobo, who had already received the news, had already met him outside the city gate.

Seeing this, Xu Huang quickly turned over and dismounted, quickly stepped forward, knelt down on one knee toward Huangfu Chaobo, and said, "finally, I'll see you king!"

"General Xu, please get up. I didn't expect that the general was so fast..." With a smile, Huangfu Chaobo stepped forward and held out his hands to help Xu Huang up, saying,

"the king flatters him, the king Tianwei, that's why he has such validity."

Then, Xu Huang made a detailed report to Huangfu Chaobo about his arrangement in Sheyan City, and then entered Qiuci city together with Huangfu Chaobo.

The next day, early in the morning, the army left Qiuci city and set out to the northeast of Baitu city.

The white earth city is located on the East Bank of Yuanshui. After passing the White Earth City, it entered the most prosperous place in the whole Hetao area, which is also called "Henan land" in the Qin and Han Dynasties. It was once densely populated, and the former South Hun king tingmeiji city was located here. However, since 188, when the southern Xiongnu got rid of the jurisdiction of the Eastern Han Dynasty, Henan was opened as a nomadic area by the northern Xiongnu, Wuhuan, Xianbei, Qiang and other minorities.

When the army crossed the Yuanshui River, Huangfu Chaobo thought there would be a war, but to his surprise, there was no war. Maybe it was because kuci and Huanyin were both conquered by Jiangshan, so Baitu city was occupied by several small and medium-sized tribes instead of big tribes.

When they found out that there was a large army coming towards the direction of huanshui in kuci City, almost all the tribes fled for the first time, so that the Tang army passed through huanshui very smoothly and occupied the white earth city.

In the general plan made by Huangfu Chaobo and several military strategists, the position of white earth city was very important, and it would be an important logistics supply for the army to fight in Henan.

Outside the west gate of Baitu is just the East Bank of huanshui. So after the army occupied Baitu City, Huangfu Chaobo immediately ordered to build a floating bridge outside the west gate that could pass through the baggage carts. At the same time, he ordered the army to strengthen the wall and defense of Baitu city. Although there were no tribes in baitucheng, Huangfu Chaobo knew that they had only left temporarily because the surrounding area had been occupied by the Han Army, and these tribes could not disappear out of thin air.

Huangfu Chaobo is right. 150 miles northeast of Baitu City, there are three old Han cities, which are not far away. They are Guangyan, Zhenlin and Pingding.

When Huangfu Chaobo strengthened the defense of the White Earth City, as many as 20000 miscellaneous bearded cavalry had gathered around the three cities, and more miscellaneous Hu cavalry were gathering towards the three cities.

These tribal cavalry are the cavalry of all the tribes in Henan Province. The first one is Liu Bao's uncle, Shan yuhuquan, who is now the southern Hun. A few years ago, huchuquan appointed Liu Bao, who had just come of age, as the king of Zuo Xian, after his father, Yu Fuluo, became the southern Xiongnu Danyu.

Later, huchuquan tried his best to weaken Liu Bao's power, and then sent him out of the court of the southern Xiongnu and arranged him in Qiuci. As a result, Liu Bao was defeated by Jiangshan with the help of Fazheng. Finally, he was captured by Jiangshan and finally had to surrender to Jiangshan.

This time, Liu Bao suddenly reappeared in Qiuci, and constantly gathered up the Xiongnu tribes and reorganized 10000 Xiongnu cavalry. The news was soon sent to huchuquan.

Huchuquan is now a hairless Phoenix, not as good as a chicken, but there is another saying that a thin camel is bigger than a horse. Even though the southern Xiongnu is far from being able to compare with the Xiongnu in the early Han Dynasty, huchuquan is not in control of Meiji and Guangyan. It has as many as 40000 or 50000 troops and about 15000 troops, which is worthy of being the largest force in Henan.However, even so, there are ten different tribes in the whole area of Henan. The total number of tribes and troops is far more than huchuquan. That's why huchuquan still can't control the whole area of Henan with 10000 or 20000 troops.

After getting the news of the Tang army's dispatch, huyanquan immediately ordered all the tribal leaders in Henan to go to Yigu Luocheng in the east of Guangyan to discuss how to defeat the invading Tang army.

It was the descendants of Qiang who occupied Xihe and Shangjun during the reign of emperor Guangdi of Han Dynasty that occupied Guluo city. The battle of attacking Guluo City happened here. In the first year of Emperor Yan Guang of Han an (122 AD), the Qiangs, who lived in Xihe and Shangjun, united with Xiongnu to rebel against Guluo city (now southwest of Zhungeer banner in Inner Mongolia). Geng Kui, a general of Du Liao in the Eastern Han Dynasty, led all the county soldiers and Wuhuan cavalry to suppress and break it.

A few decades later, the descendants of the Qiang tribe, who fled to the West in confusion, moved eastward again when the Han court was unable to control Xihe and Shangjun again, and then occupied the city where their ancestors broke the sand and sank the halberd again. However, the Qiangs at this time were already a large rebellious tribe that occupied the two counties decades ago, but a medium-sized tribe with only more than ten thousand tribes.
