Not Kong Ming, who made Lu Xun give up pursuing Liu Bei?

In 219 AD, Guan Yu defeated Maicheng and was killed by Soochow. After that, Zhang Fei beat his subordinates for revenge and died unexpectedly. After the death of Guan and Zhang, Emperor Liu Bei of the Shu Han Dynasty ignored the opposition of everyone and He personally led the army to attack Wu. At first, the situation was unstoppable. Lu Xun, the governor of Soochow, avoided his attack and refused to fight. By the time the two sides faced off at Xiaoting, it was already summer and the weather was very hot, so the morale of the Shu army gradually declined. In order to stabilize the morale of the army, Liu Bei ordered to set up camp in the mountains and forests. However, it was late summer and everything was dry, so Liu Bei set up camp in the forest again, giving Lu Xun an opportunity to attack with fire.

After careful preparation, Lu Xun ordered his troops to approach the Shu Han camp at night, and saw the opportunity to set fire to the Shu camp. In an instant, Liu Bei's camp fell into a sea of ??fire, causing heavy losses. He was protected by everyone. Fleeing back to Baidi City, in fact, the reason why Liu Bei was defeated was because Liu Bei was already upset at this time, and his eagerness for revenge caused him to lose his most basic judgment and make wrong decisions. On the other hand, Liu Bei faced Lu Xun still underestimated the enemy, which ultimately led to his own defeat. The failure of this battle greatly damaged the national power of Shu, and Liu Bei became ill as a result.

While Lu Xun was chasing Liu Bei, he fell into the formation arranged by Zhuge Liang and was unable to escape. At this moment, Zhuge Liang's father-in-law Huang Chengyan came out to guide Lu Xun out of the formation and saved Lu Xun's life. Lu Xun then gave up his pursuit of Liu Bei and returned to Soochow to guard the key areas. As for why Lu Xun was let go, some believe it was because of the following reasons:

First, we must understand the situation at that time. Although the Three Kingdoms were standing in opposition to one another, after the Battle of Yiling, the strength of the Shu Kingdom declined significantly, and The situation of Wei being strong and Wu Shu being weak has not changed. If Lu Xun pursues Liu Bei closely at this time, Shu and Wu will eventually be defeated by Wei. Therefore, Huang Chengyan's rescue of Lu Xun was actually for the future of Shu.

Secondly, Zhuge Liang did not intend to kill Lu Xun when he set up the formation. He just wanted to buy time for Liu Bei to retreat so that the Shu army could have a chance to survive. When Lu Xun was trapped in the formation, When he was unable to extricate himself, Zhuge Liang's goal had been achieved, and it was understandable that Huang Chengyan stepped forward to rescue Lu Xun at this time. This process had a strong political purpose: on the one hand, Shu needed Soochow to continue to resist Wei's ambitions, and Soochow also needed Shu's support from behind so that it could have a chance to breathe. Judging from the situation at the time, Shu The country and Soochow are inseparable. Both Zhuge Liang and Lu Xun understand the meaning of death and death, so everything is logical.
