When Lu Xun learned that Liu Bei was fleeing in the direction of Baidi City, he took coordinated land and water operations and besieged Liu Bei. Seeing Wu Jun's hot pursuit, Liu Bei told people to take off their uniforms and pile them in the middle of the road, and then set fire to stop Wu Jun. Suddenly, Zhu Ran, a general of the State of Wu, fought his way with a group of troops, and Liu Bei thought he was going to die here. Escorters Zhang Bao and Guan Xing led the troops to break through, but they were outnumbered and could not break through the enemy's siege. Eventually, they were injured one after another.
To Liu Bei's despair, an enemy army suddenly appeared behind him. When Liu Bei saw it, it turned out that Lu Xun personally led the army to chase it. Just when Liu Bei thought he was going to die, suddenly a veteran in a white robe led an army to kill Zhu and save Liu Bei. When Lu Xun saw Zhao Yun in a white robe, he immediately turned his horse's head and ordered the whole army to stop chasing Liu Bei. Why is Lu Xun so afraid of Zhao Yun's appearance? Why did Zhao Yun run away as soon as he came out? In fact, there are two main reasons:
First, the strength of Zhao Yun. At that time, Zhao Yun was very famous, and everyone knew that Zhao Yun was Liu Bei's right-hand man. Especially in the first world war in Changbanpo, Zhao Yun was surrounded by layers of Cao Jun, holding Liu Chan in his arms. Wherever he went, he was unstoppable and finally killed more than 50 generals of Cao Cao. Lu Xun was naturally nervous when he saw Zhao Yun coming to the rescue. At this time, although Zhao Yun was old, he remained brave, so Lu Xun was not sure that he could defeat Zhao Yun.
In the confrontation between Lu Xun and Liu Bei, we know that Lu Xun is a very stable person, and there is no absolute assurance that he would rather endure humiliation than go to war with Liu Bei. That's how he defeated Liu Bei in the end, so he is here. Faced with Zhao Yun's uncertainty, he decided to withdraw and not take the risk.
Second, the opportunity to capture Liu Bei has been lost. Originally, Lu Xun's plan was that Zhu Ran unexpectedly stopped Liu Bei from the waterway and then blocked him from behind, so that Liu Bei could be stopped from front to back. However, the battle of Zhao Yun not only defeated Zhu Ran's army, but also killed Zhu Ran, which made Lu Xun's original plan fall through. And this time zhaoyun is not alone to savior, but rose with tens of thousands of shu soldiers reinforcements.
The purpose of Lu Xun's pursuit of Liu Bei is to capture him alive. However, with the emergence of Zhao Yun's reinforcements, this plan will never be realized, so why should we fight Zhao Yun at the expense of our troops? Because even if we fight Zhao Yun again, it is impossible to catch Liu Bei again. After all, the battle of Yiling defeated Liu Bei, which caused heavy losses to Shu and achieved the goal of destroying Wu. So Lu Xun chose to stop fighting with Zhao Yun and directly ordered the withdrawal.
