It is controversial to say that Sima Yi was the most powerful person in the Three Kingdoms period, after all, Zhuge Liang, Cao Cao, and so on were not inferior to Sima Yi, but it is indisputable to say that Sima Yi was the biggest winner of the Three Kingdoms period, because Cao Cao, Liu Bei, and other tyrants fought and fought, and destroyed most of their competitors one after another, but the fruits of their victories were finally stolen by Sima Yi and his descendants.
Sima Yi differed from Zhuge Liang, who was loyal to the emperor and the imperial court, while the former was ambitious. As soon as Cao Rui died, the Wolf Gu Minister moved. Judging from what Sima Yi did in his life, he was only afraid of 4 people. They were Cao Cao of the Wei Kingdom, Cao Pi, Cao Rui, and Zhuge Liang of the Shu Kingdom.
In the early Three Kingdoms period, Zhuge Liang was in charge of the internal affairs of the Shu Han Dynasty, and Sima Yi was jealous of Cao Cao, and it was difficult to obtain real power, which made the two of them have no chance to fight, but in the late Three Kingdoms period, when the talents in various countries withered, the two of them relied on their own talents and became the pillar talents of their respective camps, which made them have a mobile phone meeting.
Although the Wei Ming Emperor Cao Rui did not have great ability, he could subdue Sima Yi obediently. During Zhuge Liang's first Northern Expedition, he used Ma Chen's divisive tactics to cut Sima Yi, a general on horseback, from his post to the people. This ambitious man looked at Cao Rui's holy will and only prostrated his head, and he absolutely did not dare to disrespect Cao Rui.
