Tuyuhun was originally a branch of the Murong tribe of the Xianbei in Liaodong. At first, the three characters Tuyuhun were a name, which was the eldest son of the Shanyu Shanyu of the Xianbei in Liaodong. Shegui was divided into 700 households and sent other tribes to herd. At the beginning of the 4th century, Murong Shegui died, and his legitimate son Murong Wei succeeded to Shanyu. He was incompatible with Murong Tuyuhun. Tuyuhun then led his troops to move westward to Shanglong, and ended in Qihan. Using this as a base, his descendants inherited them, invaded the Diqiang and became a strong tribe.

By the time of the Five Barbarians and Sixteen Kingdoms, the powerful Tuyuhun tribe established the Tuyuhun Kingdom, and its main ruling area was in the northern part of Qinghai Province today. It was a country that was said to be strong but not strong, but was still decent. The Southern Dynasties called it Henan; the neighbors called it Achai Lu or Ye Lu; in the late Tang Dynasty, it was called Tuhun and Tuhun.

During the Sui Dynasty, Yang Guang personally conquered Tuyuhun, destroyed the country, and set up four counties in Heyuan, Xihai, Shanshan, and Qieshi.

However, in the late Sui Dynasty, the world in the Central Plains was in chaos, and Tuyuhun took the opportunity to restore the country. When Tang unified the world, Tuyuhun was a border trouble, and Tang sent troops to attack. The Tuyuhun king was defeated and committed suicide. Tuyuhun was divided into two parts: East and West. The west surrendered to Tubo, and the east received the enthronement of the Tang Dynasty. Tubo rose, and Tuyuhun was eventually destroyed by Tubo. More than a thousand of them defected to the Tang Dynasty. Tang moved its tribes to Lingzhou and established Anlezhou. Later, Tubo captured Lingzhou, and Tuyuhun moved to the Hetao area. From Tiande Army to Weizhou, there were Tuyuhun people who moved to the east.

Tuyuhun and Shatuo people were very similar. They both fell in Tubo and were bullied by Tubo, and were responsible for heavy taxes and military service that could not be seen.

During the confrontation between the Tang and Tibet, small groups of Tuyuhun people fled from Tubo and defected to the Tang Dynasty. Among them, during the reign of Emperor Wenzong, Helian tribe, a previously unknown small tribe, fled to Fengzhou and requested their subordinates, and were then placed in Datongchuan by the court.

When he joined the Tang Dynasty, the number of Helian tribes was only 300, which was less than 10,000 people who were attached to the Shatu people. It was twenty-eight years later than Shatu's return to the Tang Dynasty. Helian Duo was the chief of the Helian tribe who was hereditary at this time. Judging from this surname, his ancestors might have been a certain Xia royal family who fled to Tuyuhun during the Sixteen Kingdoms era, and they would not be pure Tuyuhun people. Although their bravery was slightly inferior to Shatu people, they were also considered a powerful brigade among the Hu mercenaries of the Tang Dynasty.

The previous experiences of Helian and Shatuo tribes are so similar. They are both dependent on others. They are all wandering and are almost displaced. The same feeling gives them the same desire, that is, to get a territory of their own. However, Helianduo is not as strong as Li Keyong, nor is he brave enough to be Li Keyong. If he wants to take the lead in creating a rebellion of the Tang Dynasty, he will not dare to think about it, nor dare to do it. But if he can take the imperial court and steal his own territory with the cooperation of various officials and troops, why not do it?

Yu Quan was not only the newly upgraded governor of the Tiande Army, but also the elder brother of the current prime minister Yu Cong. Another brother and younger brother were also the chief officials of the Jieshou level. What's more, even a disciple, Li Jing, were the famous Zhendong Army envoy, the governor of Dengzhou and the Protector of Andong. Zhendong Army not only could fight wars, but also was a famous and rich man in the world.

If the Tuyuhun Helian tribe can get in touch with Li Jing, it will naturally be the best.

One move would take three thousand taels of gold. Following Yu Wen and Li Jing, he could drink some soup even if they ate meat.

Moreover, it is actually appropriate for the Tiande Army and Tugu Army to send troops. First, naturally, after Li Guochang's rebellion, the Zhenwu Army was next door to them. They were the first to be hit. Second, Duan Wenchu, who was killed by Li Keyong, was the former Tiande Army's defense envoy. In fact, it was also the old commander of their Helian division and the Tiande Army. No matter which point, the dispatch of troops will be very smooth.

Yu Wen was very happy to see Helianduo and Bai Yicheng's statements.

"This time, I will send troops personally. In order to be sure, I will summon 7,000 troops from Tiande Army and 3,000 troops from your army, and a total of 10,000 troops directly attack Li Guochang's old nest Shanyu Protectorate. Li Guochang's family and many generals' families are in this city. As long as we take this city, Li Guochang's foundation will have to retreat to Hedong. At that time, Zhenwu Army can be recovered." After a pause, Yu Yan made another extremely tempting decision: "As long as you can capture the Shanyu Protectorate in one fell swoop and recover Zhenwu, then I will reward Helian's army with another 3,000 taels of gold. In addition, 30% of the seized income will be returned to Helian's army!"

Originally, the three thousand taels had already made Helianduo and the other two moved. At this time, another three thousand taels came, and the promised spoils could be divided into 30%. The three of them were not hesitant at all, not to mention that among the Hu soldiers who were attached to the Tang Dynasty, Shatu, Tuyuhun, Dangxiang, Uighurs, and the Asana tribes of the Turks, Tiel's Qibi tribe and other tribes, the Shatu people have always been the strongest one among them, which is quite favored by the Tang Dynasty. This makes the Tuyuhun Helian tribe who is attached later than the Shatu people, and the number of people is not as large as that of the Shatu people.

Now there is such an opportunity in front of you. As long as you fight this battle well, the Shatu people may be doomed, and the Tuyuhun people may replace them.

Yu Guan left three thousand soldiers and horses to stay in the cities of Tiande Army, including one thousand veterans and two thousand new soldiers. He personally led the German army to fight for the 7,000 Days, including five thousand veterans and two thousand new soldiers. These seven thousand men and horses, five thousand infantry and two thousand cavalry.

In addition, five thousand troops from Helian were summoned to Tuyuhun, all of which were cavalry.

In order to recruit deputy envoys and commander-in-chief of the West Envoy, Yu Quan appointed Helianduo as deputy commander-in-chief of the West Envoy, and Bai Yicheng was the pioneer of the camp.

Before going to the war, Helianduo took out all three thousand taels of gold from the Sihai Money House. He got real gold and silver, and Helianduo was more motivated.

Yu Jun led the Tiande army to gather Helian troops in Datongchuan, and then quickly crossed Huyan Valley. Huyan Valley was originally an important gate between Xishoujiang City and Zhongaijiang City. But at this time, the guards of the Zhenwu Army at the pass suddenly turned pale when they saw the 12,000 soldiers coming from Guan Tian.

"There are a thousand soldiers and horses at the gate, and the guard is Li Ting, the brother of Li Guochang's confidant general Li Ni. This Shatuo person probably won't surrender!" Bai Yicheng told Yu Van the information he had.

"Let's attack forcefully. We have 12,000 troops, ten times the defenders, and one charge can capture the pass." Helianduo said impatiently. Tiande City is 800 miles away from the Shanyu Protectorate Mansion, the old nest of Zhenwu Army.

Between the Xishoujiang City and the Shanyu Protectorate, Zhongshoujiang City and Huyan Pass, and Niutou Formation Mountain formed a solid line of defense. Especially Niutou Formation Mountain, the terrain was dangerous. At its peak, it had 1,800 beacon shops and many large and small fortresses were built. In comparison, the only thing in the middle was Huyan Pass was better.

However, this is better, and it is only relative to the fortress group on the mountain.

"Don't rush to use force." Yu Yan shook his head with his long beard and shook his head: "Not everyone in Zhenwu Army is willing to rebel, and most of them are just being bullied by Li Guochang. The court is now in chaos, and I believe that the generals and officers of Zhenwu Army can still see the situation clearly and make a mistake anyway. I will write a letter of persuasion to surrender and let someone shoot into the city."

Helianduo said with some doubt: "Is this useful?"

Yu Wen chuckled and said, "Attacking the city is the best, attacking the heart is the best. In war, sometimes there is no need to be war. Sometimes, a letter can defeat 100,000 powerful soldiers."

After saying that, he immediately waved his hero to persuade the surrender and wrote it. He handed it over to the head of the personal soldiers and let him shoot into the city.

All the personal soldiers rushed Yu Shouguang to the bottom of the gate, causing tension at the gate. When they saw that only one person came, they became a little surprised. Yu Shouguang tied the letter to an arrow and shot it away with an arrow, and on a flagpole at the moment.

When a guard saw a letter from the arrow, he hurriedly took it off and sent it to Guanzhong.

In the palace of the guard general, Li Tingzheng discussed with several subordinates' leaders how to face the enemy. The captains were all worried. Jishou led 10,000 troops to Yuzhou to trouble him, Tuoba Sigong, who claimed to be the governor of Youzhou. At the beginning of the rebellion, the general wrote dozens of letters to send them to the tyrants of the Tang Dynasty in Daibei and Hetao.

Tuoba Sigong of Youzhou was the leader of the Dangxiang people. He took advantage of the chaos in the late Tang Dynasty to form a army of 3,000 troops. He then drove away the governor of Youzhou and claimed to be the governor. Li Guochang thought that since Tuoba Sigong had driven away the governor, he was unwilling to continue to be a vassal of Li Tang. So he asked him to do something with him, and also sent a sum of money and grain, and sent a woman from a clan to marry.

Unexpectedly, although Tuoba Sigong took the opportunity to be called the governor of Youzhou, but Youzhou was not far from Chang'an, so he did not have the intention to rebel. Moreover, Tuoba Sigong was also a rebellious person, following Li Tang as his younger brother. That was because the Li Tang in the Middle Earth was powerful. But what was his Shatuo Li family? Why did he ask him to follow Li Guochang? Tuoba Sigong rewarded all the gold and silk sent by Li Guochang to the soldiers, and the Li girl also accepted it with a smile, but she did not agree to join forces to fight against the Tang Dynasty. Not only did she not agree, she killed the envoys and sent the heads to Chang'an to seek merit.

This made Li Guochang very angry when he learned about it. He ignored the opposition of his subordinates and led his troops south to attack Youzhou and destroyed Tuoba Sigong to avenge this revenge.

Before Li Guochang left, he surrendered the city in Zhongshou, Huyanguan and Niutou faced the mountain with a thousand soldiers. In his opinion, the Tiande Army was the weakest vassal state in the Tang Dynasty. He would be good if he didn't go to conquer the Tiande Army, and the Tiande Army would not dare to mess with him.

But now, not only has the Tiande Army arrived, but also has 12,000 troops. Although Yu Jun, the governor of the Tiande Army, was a literati, Na Helianduo and Bai Yicheng had fought for the Tang Dynasty many times with the Shatu soldiers. They still knew the courage of the Helian army, and they were not weaker than the Shatu people.
