To deal with the Huns, perhaps the power of the Left Army was enough, but to deal with the more powerful Xianbei people, it was obvious that the power of the cavalry was not enough with just two cavalry battalions.

Although Cao Liang has used all his main energy to deal with Sima Shi in recent years, it does not mean that Cao Liang is indifferent to the Xianbei people outside the Great Wall. In Cao Liang's eyes, the Xianbei people have always been a big concern and want to get rid of it so quickly.

But the main reason is that the war with Sima Shi was constantly continuous, which made Cao Liang unable to free up his hands, otherwise the Xianbei people would definitely become the first enemy Cao Liang wanted to conquer.

During the Battle of Youzhou, in order to march into Liaodong, Cao Liang sent troops to destroy the Yuwen tribe and Murong tribe in the eastern Xianbei. Although it seemed like a fishing and turtle-catching, Cao Liang could clearly see that the three major tribes of the eastern Xianbei were not good, especially the Murong Xianbei, who was even more cruel and murderous. In the era of the Five Barbarians and Sixteen Kingdoms, he committed heinous crimes. Of course, Cao Liang would not show mercy to such tribes and races. As long as they could be eliminated, they would be eliminated, and no one would be left behind.

At that time, the Bingzhou army launched a bold and resolute attack, which made the Eastern Xianbei flee in a panic. In addition, there were many conflicts between the various Xianbei tribes in the Eastern Xianbei tribes, which created opportunities for Cao Liang to defeat each other. Cao Liang took advantage of the situation to defeat the Eastern Xianbei. The Murong tribe was destroyed by the entire army, and the Yuwen tribe only escaped Yuwen Mohuai himself and some remnants. Only the Duan tribe Xianbei was able to escape unscathed.

The demise of the Xianbei in the Eastern region created an opportunity for Cao Liang to completely pacify the Xianbei. Yuwen Mohuai and Duan Ri Lujuan defected to the Tuoba Xianbei one after another, which was equivalent to giving Cao Liang a statement of giving troops. Of course, there was no excuse to send troops to attack the Xianbei. They were indifferent to life and death, and they would do it if they were not convinced. Why did they really need to discuss it if they really wanted to destroy him?

However, in the end, Cao Liang chose to endure. After all, his main target was the Sima army at that time. Cao Liang could not have crossed thousands of miles to attack the Tuoba Xianbei. He could only allow Tuoba Li to slightly annex the remnants of the Eastern Xianbei, and his strength was stronger than before.

The strength of strength means that Tuoba Liwei's ambition has further expanded. Cao Liang knew that Tuoba Liwei had always been salivating about the Central Plains. Once he was given a chance, the immortal old guy would not let him go.

Others may disagree. After all, Tuoba Liwei is already an old man over 80 years old and has not had much time, so how could he have even greater ambitions and desires?

But Cao Liang knew that Tuoba Liwei was an old birthday star who lived twice as long. If Cao Liang remembered correctly, Tuoba Liwei had lived for more than 100 years in the Han, Wei and Jin Dynasties and had been living for more than 100 years. It can be said that Tuoba Liwei, who was in his eighties, was still in his prime, and his ambitions had not diminished. His desire to look at Bingzhou has not yet died. If such a terrible opponent did not find a way to eliminate him, he would definitely become a confidant enemy of Bingzhou in the future.

Especially after Tuoba Liwei moved Wang Ting to Shengle, his ambition was even more obvious. Cao Liang could not tell when Tuoba Liwei would advance, so he could only remind Wang Ji and Le Chen to always be vigilant against the enemies in the north and beware of the sudden invasion of the Xianbei people. Especially the prefect of Yanmen Le Chen, Yanmen County is the first line of defense to prevent the Xianbei people. It must rely on the dangerous terrain at the Yanmen Pass and make active defenses to prevent the Xianbei people from crossing the thunder pool.

But unexpectedly, the first attack was not Tuoba Liwei, who had moved the capital to Shengle, but Liu Yuan, who grew up from Shuofang.

Although Liu Yuan caused a considerable storm in Bingzhou, Cao Liang was calm. In his opinion, there was no need to send more troops to participate in the war. Just sending the Left Army was enough to sweep away the Huns.

Facts proved that Cao Liang had no problem with his judgment. He personally led the Left Army back to Bingzhou, defeated Liu Yuan and failed to form an army.

But the Xianbei people who had been waiting and watching actually took action at this time, but they did not take advantage of the situation to invade Bingzhou, but rescued the trapped Liu Yuan and left.

The sudden invasion of the Xianbei people made the Bingzhou army miss the great opportunity to completely annihilate Liu Yuan. Liu Yuan, who was originally doomed, finally took this opportunity to escape, which completely failed to escape.

Did the Xianbei people collude with the Huns in advance? Obviously not. If the two sides had contact in advance, then when Liu Yuan sent troops to advance east, the Xianbei people should send troops south. Such attacks from both directions seemed to pose a greater threat to Bingzhou.

The Xianbei people suddenly captured Mayi City, and they came and went quickly, just like a gust of wind, pulled Liu Yuan and turned around and fled. Their actions were very hasty. Obviously, they were not ready to go to war with the Bingzhou army this time, but just sent troops to rescue Liu Yuan.

This made Cao Liang a little puzzled. He had never heard of any entanglements or involvement between the Huns and the Xianbei people. Both sides had always had a feud before and were hoping to kill each other. Tuoba Liwei suddenly sent troops to rescue Liu Yuan. What's the trick in this?

Everyone has their own account in their hearts, and Cao Liang cannot be the worm in Tuoba Liwei's belly. How could he know Tuoba Liwei's true thoughts?

However, Liu Yuan's not dead was bad news for Cao Liang. He knew Liu Yuan's ability very well. He died without being stiff. Once Liu Yuan was given a chance, he would definitely make a comeback. What's more, this time Liu Yuan's backer was Tuoba Liwei. Such a strong alliance posed a major threat to the northern border of Bingzhou.

Therefore, the Xianbei people on the northern grasslands have become the most urgent task that Cao Liang must solve. Now the situation in the Central Plains can be put aside. Even if he crosses the river to fight again next year, there will be no delay. However, if the Xianbei people are not solved, Cao Liang will always have worries.

Cao Liang made a quick decision and ordered the mobilization of the Xiaoqi Camp and the Tunqi Camp to rush back to Bingzhou immediately before he arrived in Yanmen County, preparing to take the lead in attacking the Xianbei people.

If you attack first, you must be surprised and attack the powerful enemy like the Xianbei people. Otherwise, you will be fleeing into the desert grassland by the Xianbei people, and there will be no trace of Bingzhou army.

However, there is a prerequisite for starting the enemy first, that is, the problem of keeping cold in winter must be solved. Otherwise, the coldness on the grass source in the desert may be feared by anyone.

Cao Liang has made preparations for this in Bingzhou in recent years. Cao Liang collected fur and silk and made a large number of winter clothes, which can fully meet the equipment of tens of thousands of people. With these guarantees, Cao Liang dared to have a plan to send troops outside the border in the middle of winter.
