Tibet

The Yili River Valley, like the Suiye Basin, is a pearl among the mountains. The Yili River runs from east to west and is hundreds of miles long. On both sides of it are endless pastures and large coniferous forests, and in the distance are the snow-capped mountains.

During its thousand-year history, the Yili River Valley has always been a coveted treasure land for countless nomads due to its humid climate and rich and vast pastures.

Serbs and Usu people mainly live here, but they are relatively weak and have always existed as dependents.

During the Kaiyuan Tianbao period, this was the headquarters of the Tuqishi people. They drove away the Serbs and Wusu people and occupied the entire Yili Valley.

In the early years of Tianbao, the Tang army defeated the Tuqishi people, recaptured Suiye, and also recaptured the Yili River Valley, making the Suiye Basin, Suiye River Valley and Yili River Valley integrated into one. In particular, the Yili Valley was the starting point for Beiting to go to Suiye Valley Ye's strategic channel is extremely important to the Tang army.

The Tang army built Gongyue City in the Yili River Valley and stationed 300 troops to guard the river valley. The Sai and Wusu people who had been driven away returned to live in this rich land.

In addition to the Sai and Wusu people, there are several smaller Tuqishi tribes, which no longer threaten the Tang army's control of the Yili Valley. Li Ye, the governor of the river, agreed that they live in the west of the Yili Valley and in the east. After entering, the Wusu people live in peace.

However, the Geluolu people of the Pogo tribe living in the north have been eyeing the Yili River Valley. However, they were frightened by the Tang army and did not dare to make any move. However, the Geluolu people were not willing to give in. They had been patiently waiting for the opportunity.

The capture of Suiye City made the Geluolu people see an opportunity. They believed that the Tang army had lost power in the river, so they did not hesitate to seize this opportunity and send troops to the Yili Valley.

The Creeping Geluolu Khan is called Shaya, and he is the fourth uncle of Jinshan Ling. He actually usurped the throne of his nephew. The year before last, he led his army to fight against the Jinshan Geluolu tribe. As a result, both sides suffered losses and retreated back to Xuanhai.

Shaya was eager to regain his strength. The fastest way for the nomads to regain their strength was to annex other small tribes. This time he occupied the Yili Valley and annexed three small Tuqishi tribes, and his strength was somewhat restored.

But Shaya did not sit back and relax. He was watching the movement in Beiting. If there was no movement in Beiting, it would mean that the Tang Dynasty acquiesced to his occupation of the Yili Valley.

That morning, Shaya Khan suddenly received news from spies that a Tang army of tens of thousands was marching toward the Yili Valley. This shocked Shaya and hurriedly ordered the gathering of troops.

The eldest son Kuntli quickly advised: "Father, there are tens of thousands of people in Beiting. They are not necessarily coming for us, they should just be crossing the border to break leaves!"

Shaya Khan thought about it and it made sense, but he didn't dare to be careless. What if the Tang army killed them directly?

At this moment, another soldier came to report, "There is a letter from the Tang Army. It is a letter from the Governor of Beiting."

The soldier presented the letter, and Sha Ya read it. His face was really ugly, and he said to his eldest son: "Li Fei Shouyu asked us to retreat back to Xuanhai immediately, otherwise he will directly lead his army to attack us!"

The eldest son Kuntli was a little scared and said to his father: "It is better to retreat north temporarily, and then send people to Chang'an to ask the Emperor of the Tang Dynasty to allow us to graze our cattle in the Yili Valley!"

Shaya Khan sighed, "We didn't send anyone to congratulate the Emperor of the Tang Dynasty on his accession to the throne. How could they agree to our request at this time?"

The second son Sabat said: "Father, the relationship between Ge Luolu and the Tang army was so good in the past that Li Ye did not allow Ge Luolu to get involved in the Yili Valley. It is even less likely to agree now. We must either fight the Tang army and defeat them. Completely occupy the Yili Valley, or retreat to the Xuanhai and completely give up on the Yili Valley!"

Shaya Khan shook his head, "How can you spit out the fat that reaches your mouth?"

"Then let Hao'er lead the army to fight them. If Hao'er fails, it will be too late for Father Khan to lead his people back to Xuanhai."

Shaya Khan thought for a long time and finally nodded. How would you know if it doesn't work if you don't give it a try?

He warned: "Don't fight hard with the Tang army. Try it out. If it doesn't work, retreat immediately. To ensure the safety of the main force, we still have to fight against the Jinshan tribe."

"Father, please don't worry. I'm just testing it out. If it doesn't work, I will retreat immediately!"

Shaya Khan immediately handed over 30,000 troops to his second son Sabat, and asked him to lead the army to conduct a trial battle with the Tang army.

The eldest son Kuntli tried to persuade him again and again, but Shaya Khan refused to listen.

At night, Shaya Khan was lying in the big tent with two Geluolu girls in his arms, watching a group of girls dancing.

Suddenly the eldest son Kuntli rushed in and shouted: "Father Khan, Sabat has rebelled!"

Sha Ya was stunned, "What else are you going to say?"

"Father, please listen!"

Quantli stopped the singing and dancing. It was very quiet in the big tent. He heard shouts of killing outside. Shaya stood up and said with a pale face: "What's going on?"

"Father Khan, Sabat got the army and started to rebel."

Shaya was so angry that he yelled: "This ungrateful bastard, I'm blind!"

At this time, the guard came and shouted: "The army is coming, Khan, hurry up!"

Shaya ran out in a hurry, got on his horse and fled. His eldest son Quantli followed closely on horseback. However, after running for several miles, he was surrounded by a large army.

Shaya was so angry that he shouted: "I am Gelulu Khan, let Sabat come out to see me!"

Sabat hid in the dark and coldly ordered: "Kill them with random arrows!"

The captain of his men gave an order, and thousands of cavalry fired random arrows. Khan Shaya and his eldest son Kuntili were both killed by the random arrows.

Shaya was mean and stingy. He never distributed the property he stole to his subordinates, which made his subordinates dissatisfied. Sabat secretly bribed five captains of ten thousand in advance. With the support of the generals, Sabat became the new captain of ten thousand. , and ordered the millions of sheep stolen to be distributed to his generals, and he immediately gained unanimous support from his subordinates.

The 10,000 Beiting Army had already arrived fifty miles away. Sabat immediately led 40,000 troops to fight the Beiting Army.

Li Fei Shouyu initially did not intend to ask the Tang Army to help him in the Western Expedition. After all, the responsibilities of the two sides were different. More importantly, Li Fei Shouyu knew Sha Ya. He would not take risks. He would test and fight with him. If it was unfavorable, he would withdraw immediately. Xuanhai.

But at this time, Li Fei Shouyu got the news, and Sabat launched a coup, killed his father and brother, and seized the throne of Khan.

Li Fei Shouyu immediately became nervous. Sabat was completely different from his father. He was a madman. Li Fei Shouyu immediately led his army to retreat a hundred miles and sent people to ask for help from his brother Li Fei Yuanli.

The next day, Xi Wanli led 20,000 elite cavalry to support.

The two armies came together and Xi Wanli performed the courtesy of a junior. Li Fei Shouyu did not dare to underestimate Xi Wanli. He was the leader of the junior generation and the most valued young general by the emperor.

"General Xi, do you have any good ideas?"

Xi Wanli smiled slightly and said: "Of course it is a head-on confrontation with the opponent, but the effect will be better if the opponent's morale is demoralized before the confrontation!"

The next morning, Li Fei Shouyu received news that Ge Luolu's army had appeared twenty miles away to the west. He immediately ordered the troops to gather into a large formation.

The location chosen by Xi Wanli was very unique. They chose to be in a low place. Ten miles away was a long slope, which was very suitable for attacking from top to bottom. This was the charge route tailor-made for Sabat.

Not long after, 40,000 troops appeared at a height ten miles away. Sabat looked at the 30,000 Tang army cavalry formed in a large formation in the distance. He suddenly laughed: "I thought they were going to use the Mo Dao army! They actually wanted to use cavalry and Let’s go head-to-head, let’s give them a taste of prairie cavalry!”

He pulled out his sword and shouted: "Eagles of the grassland, let us spread our wings and kill the Tang army until they bleed like rivers!"

The 40,000-strong army raised their arms and shouted together, and like a flood that burst a dike, they swept towards the Tang army from high places and killed them.
