Twelve years after Liu Bei's death, Zhuge Liang finally died of illness in the Wuzhangyuan military camp due to overwork. In fact, Zhuge Liang already knew his physical condition, and he also knew that he would definitely not live for too long, so he was clear about the arrangements for his posthumous affairs, Zhuge Liang's biggest concern for Ji Han was not Liu Chan's incompetence, but that Wei Yan was worried that he would rebel, and he could suppress Wei Yan when he was alive, and once he died, Wei Yan would probably do whatever it took to realize his surprise attack on Meridian Valley.
Wei Yanzi Wenchang is a famous general in the middle and late Shu Han Dynasty, and he is also a member of Liu Bei who was personally raised when he was alive, but the biggest controversy about this person is whether he will rebel in the end. In fact, the debate about Wei Yan's rebellion has been going on for a long time, and in "Romance of the Three Kingdoms", it is said that Zhuge Liang said that when he saw Wei Yan for the first time, he said that he had a backbone in the back of his head and wanted to kill him;"Romance of the Three Kingdoms" said: "The original Wei Yanyi, who does not descend north and returns to the south, but wants to eliminate the killing instrument and so on."
This history was written by Chen Shou, a famous Taishi who grew up in Ji Han, and it is said that the reason why Wei Yan did not go north to surrender to Wei and chose to go south to Chengdu was actually to kill Yang Yi. Judging from the comparison of the situation between Ji Han and Wei at that time, Zhuge Liang was fashionable and could not be equal, after Zhuge Liang's death, Ji Han was even more precarious, Wei Yan should have a good future when he took refuge in Wei, so what was the reason why Wei Yan would rather give up a good future and stay in Ji Han to intercept Yang Yi?
In the historical material "Wei Luo", it is recorded that when Zhuge Liang was seriously ill, he sent a letter to Wei Yan, asking Wei Yan not to come to mourn him, but to guard Hanzhong. And put the military power in the hands of Wei Yan, secretly not mourning, Yang Yi in the Prime Minister Zhuge Liang's mansion has always been at odds with Wei Yan, he was afraid that Wei Yan would be unfavorable to himself after taking power, so he spread rumors everywhere that Wei Yan was going to surrender to Wei with people, and led troops to attack Wei Yan's headquarters, Wei Yan had no intention of rebelling, so he did not fight with Yang Yi, and left first with his troops.
Although there are relatively few records in the history of the Three Kingdoms, judging from the limited records, Wei Yan's rebellion has never been mentioned in the orthodox history, and both emphasize the discord between Wei Yan and Yang Yi, either Wei Yan wants to wait until he takes power to kill Yang Yi to get rid of the trouble in his heart, or Yang Yi wants to kill Wei Yan. But Wei Yan's withdrawal of troops on the whole line was indeed Zhuge Liang's last order, but Wei Yan made the mistake of burning all the plank roads after returning to the army, resulting in Yang Yi and other troops being unable to return to the dynasty, which is also the reason why Wei Yan was killed later.
Wei Yan from the time of Liu Bei is the Taishou of Hanzhong, and the long-term guard of Hanzhong has actually cultivated a large number of loyal people, when Zhuge Liang went on two northern expeditions, the number of soldiers and horses in Wei Yan and Hanzhong was about 30,000, these people can well prevent the southern invasion of the northern Wei State, but at the same time they can also invade the Chengdu Plain, mainly depends on how the commander and the general command, this is the key.
Wei Yan's generals have given him a lot of autonomy since the time of returning to Liu Bei, Wei Yan's No. 1 general is Xiliang Ma Dai, he himself is Ma Chao's cousin, although he is not as brave as Wanfu, but he is also the best among people, Ma Chao blessed Liu Bei to take good care of him before he died, so he was arranged under Wei Yan. Wei Yan's son Wei Changzhi is of average ability and has not inherited his father's fine traditions.
In fact, outside of Ma Dai under Wei Yan, Wei Yan himself does not have many strong generals, and in the history of the Three Kingdoms, Wei Yan was killed later, in fact, it was from Ma Dai's handwriting, when he was at the city gate of Hanzhong, Ma Dai unexpectedly killed Wei Yan, this is because he has worked with Wei Yan for a long time and has gained Wei Yan's trust, but in fact, it is also possible that starting from Liu Bei, the purpose of arranging Ma Dai to Wei Yan's side is to monitor Wei Yan.
Wei Yan didn't see General Ji Han at all after Zhuge Liang's death, except for Jiang Wei and Wang Ping, no one could get into his eyes, so Ma Dai at this time was actually the person with the best chance to kill Wei Yan, because Zhuge Liang handed over part of the military power to Yang Yi before he died, so Wei Yan could hardly calm down, Wei Yan burned the plank road in order to snatch military power, in order to kill the rotten Confucian Yang Yi, and by the way, he continued the Northern Expedition to Cao Cao and became Zhuge Liang's successor.
In fact, Wei Yan is too impulsive to do things, if he doesn't insist on going his own way, then he won't die, on the contrary, Yang Yi's military power is only temporary, that is Zhuge Liang is paving the way for Jiang Wei, Jiang Wei, Fei Yi, if Wei Yan is obedient, Ma Dai will not kill Wei Yan, and then Wei Yan can continue to be his own Hanzhong Taishou, and then act when he has the opportunity, and cooperate with Jiang Wei to continue the Northern Expedition, wouldn't it be beautiful?
