Sima Yi, the biggest winner in life, lived a long life. He survived three important figures, Cao Cao, Cao Pi and Cao Rui. Sima Yi is a master of health preservation. Although Cao Cao is a shrewd man, he has never lived Sima Yi. There are many smart people in the history of the Three Kingdoms, but most of them died young. They don't pay attention to their personal lives, and they don't calculate the length of life in their destiny. Sima Yi lived through everyone. Sima Yi not only pays attention to the width and height of life, but also pays attention to the length of life. He turned his life into a three-dimensional space.

Cao Cao admired and envied Sima Yi's talent. He once gave Sima Yi a series of examination questions to see if it had any ambition to win the world. Sima Yi gave Cao Cao's most reasonable answer with his cleverness, without revealing his ambition, and relieved Cao Cao's doubts about himself. Before Cao Cao died, he still did not fully trust Sima Yi. He told Cao Pi that Sima Yi could never be reused and the military power could not be handed over to him. This is Cao Cao's final evaluation of Sima Yi.

If in peacetime, Cao Cao and Sima Yi may be able to make friends for a change, but it is a pity that smart people and smart people can't survive in troubled times. Sima Yi's political career has been ups and downs, but all this has not shattered his confidence. A person who achieves great things can endure the sufferings that others can't eat and the grievances that others can't stand. Sima Yi put up with humiliation and drag out an ignoble existence, waiting for an opportunity to win. Both Cao Pi and Cao Rui fell at Sima Yi's feet and lost their lives to Sima Yi.

Cao Fang, a hairless child, inherited the inheritance of Wei, and Cao Shuang shouldered the heavy responsibility of rejuvenating Wei. But Cao Shuang had no such talent, and was no match for Sima Yi. Sima Yi finally ushered in the last glorious moment of his life. He took the opportunity to launch a coup in Gao Ping Ling and seized the state power of Wei in one fell swoop.
