Sima Yi was a powerful minister of Wei during the Three Kingdoms period, resourceful, good at power changes, and not only that, but his military talent was very prominent. In Sima Yi's life, he basically won every battle, except for the confrontation with Zhuge Liang across the Weishui in Wuzhangyuan, and he did not dare to fight Zhuge Liang head-on, Sima Yi basically never lost.
For example, in the "Battle of Xiangfan", Sima Yi and Jiang Ji suggested to Cao Cao that they should unite with Sun Quan and sneak attack Guan Yu's back road, and in the end, Cao Cao acted according to the plan, and Guan Yu was defeated.
Sima Yi beheaded Meng Da, Ping Liaodong, punished Cao Shuang, destroyed Wang Ling, and achieved brilliant victories in military affairs many times, from undefeated, it can be seen that Sima Yi is a powerful figure comparable to Cao Cao.
Cao Cao sensed that Sima Yi had the appearance of "eagle and wolf", and wanted to kill Sima Yi many times, but because Cao Pi and Sima Yi had a good relationship, Cao Pi pleaded with Cao Cao many times, and Sima Yi escaped.
The Book of Jin records: The emperor is jealous inside and wide outside, and there are many power changes in suspicion. Emperor Wei Wucha has heroic ambitions, and he smells of wolves. I want to prove it. It is a call to go forward, to turn back, and to face backwards without moving. I also tasted the dream of three horses eating the same trough, which was very evil. Because the crown prince said: "Sima Yi is not a human minister, and he will foresee your family affairs." "The prince and the emperor are good, and they are all blessed, so they are exempt.
Sima Yi's survival was simply a catastrophe for Cao Wei, so that later Sima Yi launched the "Gaopingling Incident", killed the general Cao Shuang and all his henchmen, usurped Cao Wei's power, controlled the government, and laid the foundation for his grandson to seize Cao Wei's country.
It can be said that without the foundation laid by Sima Yi, there would have been no later Sima Yan to establish the Jin Dynasty.
Sima Yi is highly talented, and his eldest son Sima Shi is also a talent, as eloquent as Sima Yi, Sima Shi is not only heroic and decisive, but also very skillful.
When Gao Pingling changed, Sima Zhao learned the news that he didn't sleep well during the tense night, but Sima Shi was calm and calm, as usual, and slept peacefully.
At that time, it was also Sima Shi who raised his arms and shouted, and the 3,000 dead soldiers who were free-roaming in the people came out together, and Sima Shi led the troops to control Sima Gate, which stabilized the situation.
When it came time for Biqiujian and Wenqin to rebel, Sima Shi personally led his troops to suppress the rebellion and eradicate a great danger for the Sima clan.
Sima Shi also killed Li Feng, the commander of Zhongshu, and Zhang Ji, the father of the empress, and killed Xiahou Xuan, the general of Zhengxi, eradicating another major safety hazard.
Although Sima Shi's comprehensive ability is not as good as his father Sima Yi, he is also a powerful figure second only to his father.
In the Sima Zhao period, although Sima Zhao's talent and ability were not as good as his elder brother Sima Shi, he also had a certain skill.
Sima Zhao personally led 260,000 troops and successfully suppressed Zhuge Dan's rebellion and swept away another major threat.
Sima Yi quelled the rebellion of Wang Ling, the first rebel of the "Huainan Three Rebellions", Sima Shi quelled the rebellion of Qiu Jian and Wenqin, the second rebels of the "Huainan Three Rebellions", and Sima Zhao quelled the rebellion of Zhuge Dan, the third rebel of the "Huainan Three Rebellions".
Huainan three rebellions, Sima Yi's father and son, each pacified one, and all succeeded.
After Zhonghui destroyed Shu, he made a rebellion in Chengdu, and Sima Zhao personally stationed troops in Chang'an, controlled the situation, successfully defeated Zhonghui's ambitions, and quelled Zhonghui's rebellion.
The only thing Sima Zhao did was to kill the emperor Cao Chao on the street, which was not only more ruthless than his father Sima Yi and brother Sima Shi, but also rare in the entire Chinese history.
When it came to Sima Yan, although Sima Yan forced Emperor Cao Huan of Wei Yuan to make Chan Rang and established the Jin Dynasty, Sima Yan did not want to make progress in the later period, and only thought about playing in the harem of beautiful women in a sheep cart every day, indulging in wine, and politically, he did not have any achievements, which was too far worse than his father Sima Zhao.
When Sima Yan's son Sima Zhen succeeded to the throne, it was even worse, Sima Zhen was a fool, worse than Sima Yan.
It can be said that the Sima clan started from Sima Yi, one generation is not as good as the next, and the generation is worse than the next, it can be said that "one crab is not as good as one crab", and in the end, it led to the "Eight Kings Rebellion" and "Five Hu Chaohua", resulting in the short-term unification of the Western Jin Dynasty.
