Li Jing's quick victory disrupted the overall deployment of the situation in the Central Plains by one person, who was the new king of Mobei, Chuluo Khan.

In order to better deal with the affairs of the Central Plains, Chu Luo Khan deliberately moved the Han court from the Altai Mountains, which were thousands of miles away, to the foot of Yin Mountain. It is only a hundred miles away from Dingxiang City in the Tang Dynasty.

Ke Dun is the princess of Yicheng of the Sui Dynasty, and she is Yang Guang's own sister. She heard that her younger brother was killed by the traitor Yu Wenhua, and the Central Plains was in turmoil, and she was angry. He tried his best to persuade Chu Luo Khan to actively intervene in the affairs of the Central Plains, preparing to wait until the situation in the Central Plains was under control before restoring the Yang family's temple and the Sui Dynasty's Sheji.

Unexpectedly, the 5,000 cavalry sent to Bashu by the Luo Khan was defeated by 800 people from the Tang Military Region.

He couldn't help but be furious, so he scolded the general who led the army, and ordered to be beheaded immediately.

Turning his head, Chu Luo Khan, who was deep in thought, was very depressed in his heart, he could never have imagined that there were such powerful figures among the generals of the Tang Dynasty.

It has only been a few months since Luo Khan inherited the throne, and his position is not very solid, and there are still many people who oppose him in the Mobei steppe. As soon as this incident came out, it became the reason for those opposition parties to attack and suspect him.

I remember that last year, before the death of the first Khan, Shibi Khan, he confessed to Chuluo Khan - Tang Duke Li Yuan will be your worst enemy, and you must do everything to defeat him!

Now, it seems to have come true.

Over the years, the Turks were strong and strong, and they were once the masters of the whole world. The various forces in the Central Plains, such as Dou Jiande of Hebei, Wang Shichong of Luoyang, Xiao Mo of Jiangling, and Du Fuwei of Huainan, all paid tribute to the Turkic Khan.

Li Yuan, like them, sent a generous tribute every year. But Li Yuan is different from them, Li Yuan's power has expanded rapidly in the past two years.

From the very beginning, he raised troops in Jinyang, and only possessed the land of one state; Up to now, it has been the land of Hedong, Longyou, Guanzhong and Bashu. The Central Plains is divided into three parts of the world, and Li Yuan has already possessed two of them.

Not only that, but Li Yuan also single-handedly supported the Tongye Hu Khan, accelerating the process of his unification of the Western Turks. In just two or three years, he developed from a tribal prince to the king of the Caspian Sea and became the Great Khan of the Western Turks.

His power stretched from the Caspian Sea in the west, the Hindu Kush Mountains in the south, Lake Balkhash in the north, and the Tarim River in the east, and he had become a formidable enemy of Chuluo Khan.

When the former Khan of Mobei Shibi Khan realized Li Yuan's awesomeness, it was too late, and when he was about to lead a heavy army south to Chang'an, he fell seriously ill and died.

The successor Chuluo Khan's position has not yet been secured, so it is naturally impossible to launch a large-scale military operation against Li Yuan.

Even so, Chu Luo Khan still did not give up, and he put his hope of pinning Li Yuan on the Hedong battlefield.

Time flies quickly, and in a blink of an eye, it has come to September, when the horses on the grassland are fat, and the soldiers are also in high spirits.

On the Tang side, the 30,000 soldiers and horses led by Pei Lin gained the upper hand after several fierce strategies. Pei Lin couldn't help but start to be complacent.

He actually didn't know that this was just some sweetness that Song Jingang intended to give him. In order to make Song Jingang play enough, Chu Luo Khan even let him deliberately lose a few battles.

Winter is about to begin, when the land will be frozen, supplies will be difficult, and the war will be even more difficult.

Since the two sides had been facing each other on the Hedong battlefield for a whole summer, Pei Lin was unwilling to delay any longer, and he was looking for every opportunity to fight a decisive battle.

In the subsequent battles, Pei Lin always ordered the Tang army to attack on all fronts, rushing and striking fiercely.

Song Jingang couldn't resist it, so he retreated. Pei Lin ordered the whole army to chase after him until he reached a place called Bird Mouse Valley.

The Tang army suddenly found that the enemy troops in front of them had suddenly disappeared, and the road ahead had been tightly blocked by rough logs and boulders.

When Pei Lin turned back, he found that the way had also been blocked, and the Tang army had completely fallen into the pocket array set up by the enemy.

In this narrow mountain valley, the Tang army could not be used. Pei Lin then ordered the death squad to charge at Taniguchi, hoping to break out.

Unexpectedly, what awaited them was a dense rain of arrows like a swarm of locusts. The news was cut off, and it was impossible for reinforcements to come; Water sources and supplies were also cut off, and the Tang army could only starve to death.

When the Tang army was hungry and weak, Song Jingang led the Turkic cavalry, carrying scimitars and crossbows, and launched a fierce attack on the valley.

Back and forth, the Tang army had no power to fight back, and almost all the troops were annihilated.

Song Jingang only left a few hundred followers for Pei Lian, so that they could go back and report the news.

After that, the Turkic soldiers and horses pressed the border, the land east of the river was lost, and Chang'an was shaken!
