According to historical records, Liu Bei was chanting a person's name before he died. This man is not Zhuge Liang in Wolong, but a very mysterious figure named Hidden Crane. Who is the hidden crane? The night before the defeat of Yiling Campaign, Liu Bei had a dream that an old man was fishing by the river. Liu Bei is curious and wants to say something. At this time, the old man suddenly said to Liu Bei, is the visitor Uncle Liu? Liu Bei replied, you are very accurate. Then the old man said, your final destination is Baidicheng. If you want to keep Shu stable for a long time, you must find another good man to help Liu Chan. Liu Bei asked him who he was. Then, the old man disappeared into a wisp of smoke, leaving only the word hidden crane in the sky.
As the old man expected, the battle of Yiling ended in Liu Bei's failure, and Liu Bei fled to Baidicheng, heartbroken. A lot of people gathered around him, but he couldn't find the man named Yin He. In desperation, he called Zhuge Liang to his side and talked about it alone. Although I don't know whether this dream is true or not, from the perspective of historical development, it is this old man who predicted that Zhuge Liang could not resist the Shu and Han dynasties. No matter what he does, there is always a loophole. This was particularly evident in the Northern Expedition. Ma Su and Li Yan held Zhuge Liang back, and the logistical support of Shu Han became the weakness of Zhuge Liang's army.
After this disastrous attack, Shu lost its ability to compete with the world. Liu Bei didn't expect to lose to Lu Xun, who was less than 40 years old at the age of 60. Since then, Liu Bei's fame has plummeted, and Lu Xun's fame has grown on the basis of the success of burning camp.
