At the end of the Eastern Han Dynasty, the world was divided into three, and the three kingdoms were in turmoil for nearly a hundred years. During this period, warlords were divided and heroes were born. In the end, the Sima family can rule the world, and it is inseparable from one person, and this person is Sima Yi. Sima Yi was originally a courtier of the Eastern Han Dynasty, but later became a vassal of Cao Wei. Later, after the death of the three generations of the Sima family, he usurped the power of Cao Wei and became the de facto ruler of Cao Wei, laying the foundation for Sima Shi to change dynasties. Sima Yi did not stage a coup d'état until he was seventy years old, killing Cao Wei's cronies and seizing power.
Many wild history novels have stories about Sima Yi. As early as when Cao Cao was alive, he saw that Sima Yi was a great threat. It is also for this reason that although Sima Yi is very talented, he has not been valued by Cao Cao, and Sima Yi has been serving Cao Cao in Cao Camp for the sake of Mingzhe's self-preservation, not exposing his ability.
In fact, even if Sima Yi in the early days wanted to get ahead, he didn't have a chance. When Cao Cao was alive, there were many strategists and fierce generals. First of all, the strategists Cheng Yu and Jia Xu around him were all top talents, while the military generals had loyal and fierce generals such as Zhang Liao and Xiahou Huan, and there was no ambiguity in fighting. At that time, Sima Yi was not only young, but also had a very low official position. For such a person, Cao Cao would definitely not put him in his eyes, nor would it be Sima Yi's turn to give Cao Cao advice. Even if Sima Yi was talented, he could not show it.
The real use of Sima Yi should be Cao Pi, because in the dispute between Cao Pi and Cao Zhi, Sima Yi was on cao Pi's side. In the end, Sima Yi got an opportunity to show his talent because he stood on the right team. Sima Yi rose through the ranks since Cao Pi succeeded to the throne and became an important figure in Cao Wei's political center system, but his main job was some government affairs, and he was not in charge of the army. The real military power was still in the hands of the descendants of the Cao and Xiahou clans. In Cao Pi's view, Sima Yi was an outsider, far less reliable than his own family.
Sima Yi's greatest skill is to live a long time. The average life expectancy of ancient people was very low, but Sima Yi lived a long life, and three generations of the Cao family died, but Sima Yi was still very healthy and alive. Before Cao Pi's death, of the several ministers who remained to assist Cao Rui, only Sima Yi remained. Cao Wei had no talent available at that time, so Sima Yi began to lead the army at this time, holding the military power in his hands.
Cao Cao did not take Sima Yi in his eyes when he was alive, but when Cao Pi was in power, he was deeply impressed by Sima Yi's conscientious work, and he was not bad to him, at least he would not be regarded as a traitor and traitor, and he would be on guard everywhere. But Cao Rui was different. Sima Yi was a minister left by his father to help him. He entered the dynasty for many years and was the elder of the three dynasties. Later, he took over the military power. For such a person, we must guard against him. However, Cao Rui was a short-lived emperor who died at a young age, and he did not survive Sima Yi.
After Cao Rui's death, he left the throne to the little emperor Cao Fang. Of course, when Cao Fang was young, she could not handle major state affairs. At that time, the power was controlled by Cao Shuang, the general of the Cao family, who was not a very wise and courageous person. At this time, although Sima Yi was old, he saw the opportunity to fight back. Therefore, Sima Yi pretended to yield, made Cao Shuang let down his guard, and launched a coup d'état when Cao Shuang and Cao Fang were out worshipping, seizing Cao Wei's power.
At this time, Sima Yi was already an old man in his seventies. To tell the truth, he had not rebelled before, not because he had no ambition, but because he knew he was not strong enough. Cao Cao, Cao Pi, and Cao Rui are all capable people. As long as they were there, Sima Yi would be suppressed. All he was waiting for was an opportunity, and that opportunity didn't come until he was seventy. Fortunately, at the end of his life, Sima Yi seized this opportunity.
