Tuyuhun was originally a branch of the Xianbei Murong Department in Liaodong. Originally, the three characters of Tuyuhun were a personal name, which was the eldest son of the Xianbei Murong clan in Liaodong Shan Yu Shegui, and the 700 households were divided into households to make other departments to herd. At the beginning of the 4th century, Murong She's death, his sister-in-law Murong Diao succeeded to Shan Yu, and Murong Tugu Hun was at odds.

By the time of the Five Hu and Sixteen Kingdoms, the powerful Tuyuhun established the Tuyuhun State, and its main ruling area, in the north of today's Qinghai Province, was a country that was not strong but weak, but it was still passable. The Southern Dynasty called it the Henan Kingdom; The neighboring tribes call it Achailu or wild captivity; In the late Tang Dynasty, it was called retreat and turbidity.

By the time of the Sui Dynasty, Yang Guangqin conquered Tuyuhun, destroyed the country, and set up 4 counties in Heyuan, Xihai, Shanshan, and the last 4 counties.

However, in the last years of the Sui Dynasty, the Central Plains was in turmoil, and Tuyuhun took the opportunity to restore the country. To the Tang Dynasty unified the world, Tuyuhun was a border trouble, Tang sent troops to attack, the king of Tuyuhun was defeated and committed suicide, and Tuyuhun was also divided into east and west. The western part was subjugated to Tibet, while the eastern part was canonized by the Tang Dynasty. The Tibetan rose, and the eastern Tuyuhun was finally destroyed by the Tibetans. Among them, more than 1,000 accounts defected to the Tang Dynasty, and the Tang Dynasty migrated its troops to Lingzhou, placed Anle Prefecture, and then Tubo captured Lingzhou, and Tuyuhun moved to the Hetao area. From the Tiande army to Ulzhou, there were scattered Tuyuhun people everywhere.

The Tuyuhun and Shatuo people are very similar, both have fallen to Tibet, been bullied by the Tibetans, and have to bear heavy taxes and military service that will not see the light of day.

During the confrontation between Tang and Tibet, small groups of Tuyuhun people fled from Tibet and defected to the Tang Dynasty. Thereinto. At the time of Wenzong. A small tribe of the Tuyuhun people, the Helian tribe, which had not been known before, fled to Fengzhou. asked for a subordinate, and was subsequently placed in Datong River by the imperial court.

When the Tang Dynasty was surrendered, the number of Helian tribes was only 300 tents, which was less than the 10,000 people when the Shatuo people were attached, and the time was also 28 years later than Shatuo's return to the Tang Dynasty. Helian Duo was the hereditary chief of the Helian tribe at this time, and judging from this surname, his ancestor may have been a certain Xia royal family who fled to Tuyuhun during the Sixteen Kingdoms era. It won't be a pure Tuyuhun person. Although their bravery was slightly inferior to that of the Shatuo people, they were also a strong force among the Hu mercenaries of the Tang Dynasty.

The previous experiences of the Helian Department and the Shatuo Department were so similar, they were both under the fence, and they were both upside down, and they could almost be said to be difficult brothers. The same feeling gives them the same desire to get a piece of their own. It's just that Helian Duo's strength is not as strong as Li Ke's, and his courage is not as big as Li Ke's, and if he wants to provoke the Tang Dynasty's rebellion, he still doesn't dare to think about it, let alone do it. But if it can be under the banner of the imperial court. With the cooperation of officials and troops from all walks of life, they grabbed their own territory. So why not?

Yu Xuan is not only the festival envoy of the newly promoted Tiande Army, but also the elder brother of the current prime minister Yu Cong, and the other elder brother and younger brother also serve as the feudal officials at the level of the festival commander. What's more, even a protégé, Li Jing, is now the famous military envoy of the Zhendong Army and the protector of Dengzhou Assassin and Anton. The Zhendong Army is not only capable of fighting, but also famous and rich in the world.

If Tugu Hun He's Lianbu can get in touch with Li Jing, it will naturally be the best.

As soon as he made a move, it was three thousand taels of gold, and with Yu Xuan and Li Jing, he could also drink soup when they ate meat.

Moreover, it is actually appropriate for the Tiande Army and the Tugu Army to send troops. First, naturally, after Li Guochang's rebellion, the Zhenwu army was next door to them, and they bore the brunt. Second, Duan Wenchu, who was killed by Li Keyong, was the former defense envoy of the Tiande Army, and he was also the old commander of their Helian Department and the Tiande Army. Either way, this dispatch will go very smoothly.

Seeing Helian Duo and Bai Yicheng's statements, Yu Xuan was very happy.

"This time the commander will personally send troops, in order to be foolproof, I will gather 7,000 soldiers and horses of the Tiande Army and 3,000 men and horses of your department, a total of 10,000 horses, to directly attack Li Guochang's nest Shan Yu Duhufu. Li Guochang's family and the families of many generals are in this city, as long as we take this city, Li Guochang's foundation will be lost, and he will have to retreat to Hedong. At that time, the Zhenwu army can be recovered. After a pause, Yu Xuan threw out a very tempting decision: "As long as this battle can win the single Yudu Hufu in one fell swoop and recover Zhenwu, then the commander will reward Helian with another 3,000 taels of gold." In addition, thirty percent of the proceeds of the seizure will go to the Helian Department! ”

Originally, three thousand taels had already moved the hearts of Helian Duo and the others, but at this time, another three thousand taels came, and they were promised that the spoils would be divided into thirty percent. The three of them still had the slightest hesitation, not to mention, among these Hu soldiers attached to the Tang Dynasty, Shatuo, Tuyuhun, Dangxiang, Uighurs, as well as the Turkic Ashina Division, Tiele's Qibi Division and other departments, the Shatuo people have always been the strongest among them, and they were quite favored by the Tang Dynasty, which made the Tuyuhun Helian Division, which was later than the Shatuo people attached and the number was not as large as the Shatuo people, very envious.

Now there is such an opportunity in front of us, as long as this battle is fought, the Shatuo people may not recover, and their Tuyuhun people may be able to replace them.

Yu Xuan left 3,000 soldiers and horses to guard the cities of the Tiande army, including 1,000 veterans and 2,000 recruits. He personally led 7,000 German troops to the battle, including 5,000 veterans and 2,000 recruits. The seven thousand men and horses, five thousand infantry, and two thousand cavalry.

In addition, he summoned 5,000 soldiers and horses of the Tuyu Hun Hehe Company, all of whom were cavalry.

Yu Xuan was the deputy envoy and the commander of the western camp, and he appointed Helian Duo as the deputy commander of the western camp, with Bai Yicheng as the vanguard of the camp.

Before the expedition, Helian Duo took out all the three thousand taels of gold from the Four Seas Money Village, and the real money and silver were in hand, and Helian Duo was even more motivated.

Yu Xuan led the Tiande army to converge the Helian troops and horses at Datong River, and then quickly crossed the Huyan Valley. Huyan Valley was originally an important pass between the Western Surrender City and the Zhongai Surrender City. But at this time, the 1,000 Zhenwu army guards on Guan Tian saw the 12,000 soldiers and horses coming from Guan Tian, and their faces immediately turned white.

"There are 1,000 soldiers and horses on the pass, and the guard is Li Ting, the brother of Li Guochang's confidant Li Ni. This Shatuo people are not expected to surrender! Bai Yicheng told Yu Xuan the information he had.

"Let's attack, we have 12,000 soldiers and horses, ten times the defenders, and we can take the pass with one charge." Helianduo said impatiently. Tiande City and the old nest of the Zhenwu Army are only 800 miles away from the Duhu Mansion.

Between the western surrender city and the single capital protectorate. In the surrender of the city and the Huyan Pass. And the bull's head formed a strong line of defense against the mountain. In particular, the bull head is facing that mountain, the terrain is dangerous, there are 1,800 beacon shops at the peak, and there are many large and small fortresses. In comparison, only the Huyanguan in the middle is better.

However, this one is better, and it is only relative to the fortress group on the hill of the middle surrender and the bull's head.

"There is no hurry to use force." Yu Xuan shook his head with his long beard in his hand: "Not everyone in the Zhenwu Army is willing to rebel, most of them are just coerced by Li Guochang." At present, the court is chaotic and majestic. Ben Shuai believes that the generals and colonels of the Zhenwu Army can still see the situation clearly and put things right. Ben Shuai wrote a letter of persuasion and let people shoot into the city. ”

Helianduo said with some skepticism, "Is this useful?" ”

Yu Xuan chuckled: "Attack the city for the bottom, attack the heart for the top." In battle, sometimes it is not necessary to have swords, and sometimes, a letter can defeat 100,000 male soldiers. ”

After speaking, he immediately wrote the persuasion to surrender and handed it to the head of the pro-soldier team. Let him shoot into the city.

The pro-soldiers rushed to the pass on their horses in Shouguang, causing tension in the pass. When I saw that only one person was coming. I was a little surprised. Yu Shouguang tied the letter to the arrow, and shot an arrow on a flagpole at the juncture.

When some guards saw that there was a letter on the arrow, they hurriedly took it down and sent it to the gate.

In the Guannai Guard's Mansion, Li Ting was discussing with several of his subordinates how to meet the enemy. The captains were all worried, and the commander took 10,000 horses south to kill Youzhou, and troubled Tuoba Sigong, who claimed to be the assassin of Youzhou. At the beginning of the Dashuai uprising, he wrote dozens of letters and sent them to the Tibetan tribes attached to the Tang Dynasty in Daibei and the Hetao area.

Tuoba Sigong of Youzhou was the leader of the Dangxiang people, and took advantage of the rebellion in the late Tang Dynasty to form a team of 3,000 soldiers and horses among the warriors in the Dangxiang clan. Later, he drove away the history of the assassin in Youzhou and called himself the history of the assassin. Li Guochang originally felt that since Tuoba Sigong drove away the assassin history, he was also unwilling to continue to be Li Tang's vassal. So he asked him to do something with him, and he also sent a sum of money and food, and sent a woman from the clan to marry.

Who knew that although Tuoba Sigong took the opportunity to call the assassination history according to Youzhou, Youzhou was not far from Chang'an, so he did not have the heart to rebel. Moreover, Tuoba Sigong is also a rebellious person, and he follows Li Tang as a junior brother, which is because Li Tang is powerful in Middle Earth. But what is the Li family, and why should he follow Li Guochang? Tuoba Sigong rewarded the soldiers with all the gold silks sent by Li Guochang, and the Li woman also laughed, but she did not agree to join forces against the Tang Dynasty, and not only did she not agree, but killed the messenger sent and sent her head to Chang'an to ask for merit.

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

Before Li Guochang left, he had 1,000 soldiers and horses in Zhongshou Chengcheng, Huyanguan and Niutou Chaonashan. In his opinion, the Tiande Army is the weakest feudal town in the Tang Dynasty, and if he doesn't fight the Tiande Army, the Tiande Army will not dare to provoke him.

But now, the Tiande army is not only here, but also 12,000 men. Although Yu Xuan, the envoy of the Tiande Army, was a literati, but Na Helian Duo and Bai Yicheng had fought for the Tang Dynasty many times together with Shatuo soldiers before, and they still knew the bravery of Helian and were not weaker than those of Shatuo.

Yu Xuan's letter of surrender first made the current situation clear, and then set a very good condition in the letter, as long as the soldiers on the gate opened the city to surrender, they would not be blamed for the past, and if Li Guochang's henchman Li Ting was caught and offered, there would be a lot of rewards.

This letter was first received by Zhou Xun, the town general of Huyan Pass, he is the old man of Zhenwu Army, since Li Ting arrived, although he is still the guard of this pass on the surface, but in fact, the power in his hands is all taken by Li Ting, and Li Ting is rude, and he is responsible for scolding and whipping the soldiers in Guanzhong, which has already caused dissatisfaction among everyone. Today, Li Ting convened the captains in the mansion to discuss the matter, but he, the town general, was asked to inspect outside.

After reading this letter, he only thought about it for a moment, and he understood what the situation was now. Immediately, he quietly gathered a group of henchmen and soldiers under his command and quietly surrounded the mansion where Li Ting was. Then he entered directly with a sword, and when Li Ting saw Zhou Xun carrying a sword and leading his troops to break in, he was very angry and scolded.

Zhou Xun had already stepped forward and directly assassinated Li Ting with a sword, and then displayed Yu Xuan's surrender letter in front of the captains.

"We were originally a soldier of Zhenwu in the imperial court, and Zhu Xie Chixin, a man from Shatuo, was plotting against his father and son, and we were coerced for a while, but my heart has always been towards the court. Now, Marshal Yu is leading the army to come, and it is the time for us to wait anyway. Now that Li Ting, a Shatuo person, is dead, as long as the rest are anyway, they don't care about their crimes! Zhou Xun shouted.

Those generals only reacted from their shock at this time, and when they saw the murderous Zhou Xun, as well as the blood still dripping from his sword, and the guards brought by Zhou Xun on the side, they didn't know how to choose at the moment. So one by one, Zhou Xun cut off Li Ting's head and carried it, rushed to the front of the pass with the captains, and ordered the switch to welcome Yu Xuan's soldiers and horses into the city.

Huyan Pass slowly opened, and after a while, all the guards in the city went out of the city, and the town general Zhou Xun personally came to the front to present Li Ting's head, claiming to be anyway. Yu Xuan warmly lifted him up, and pardoned them on the spot.

Helian Duo sighed at this time: "Yu Shuai wrote a letter, and the soldiers took the city without blood, and obeyed!" (To be continued......)
