The protagonist of this story is Huan Wen, a general of Jin Dynasty. At that time, it was written to Emperor Wen of Jin that he wanted to attack Western Shu. However, in the face of such a request, the civil servants in the Qing Dynasty were in a state of questioning him. Huan Wen didn't get any support in the imperial court at that time, so he had to lead his own army to the west of Shu.
After entering the land of Sichuan and Sichuan, Huan Wen made contributions to the rulers with his determination to die. What he didn't expect was that he led a great army against the current, and the whole western Shu was unprepared for his arrival. It can be said that he was not hindered before he arrived in Chengdu, the important town of Xishu.
In this battle, the Jin army led by Huan Wen is far less than the Shu army in number, but the strength of the Shu army is always in a state of dispersion, and the Shu army with low combat effectiveness always seems unable to compete with the Jin army.
In the final decisive battle, the vanguard of the Jin army suffered a heavy blow from the Shu army, and the retreat of the vanguard greatly reduced the morale of the whole Jin army. After many unsuccessful breakthroughs, Huan Wen decided to quit in order to avoid greater losses. After making up his mind, Huan Wen ordered his messenger to convey the instructions of retreat to the former army, but the messenger who was frightened by the battlefield misunderstood Huan Wen's order and turned it into an attack.
Unexpectedly, after hearing the herald's wrong news, the former army was in high spirits and rushed to the Shu army camp, but the Shu army was frightened by these Jin troops who attacked again. Finally, the Shu army with chaotic morale was routed thousands of miles. In the face of such a situation, Huan Wen is also smiling. In his view, the victory of this war is very interesting. He has died on the battlefield with the determination to die. Unexpectedly, a wrong command made him win such a big victory.
