Sima Yi was a timid scholar when he was young, but because his father also participated in the assassination of Cao Cao, Sima Yi had to use his wisdom to save his family. At this time, Cao Cao noticed Sima Yi and asked him to enter the DPRK as an official. Sima Yi used his own strategy to win the position of prince for Cao Pi, thus helping Cao Pi to be king and carry out the New Deal.
Sima Yi's personality is really interesting, but he is not as awesome as depicted in the League of Military Strategists, just as Zhuge Liang is not so divine in the Romance of the Three Kingdoms! There are several interesting details in the military division alliance, which are also recorded in the history books:
For example, Cao Cao tested Sima Yi to see if he had an "eagle eye", which is recorded in the history books as a "wolf aunt", meaning that this person can turn his head directly without turning his head, which is very similar to the nature of a wolf. The other is that Cao Cao dreamed that "Sanma ate the same food", and Cao Cao called Yang Xiu out to interpret the dream. Unfortunately, Yang Xiu has been killed by himself. Actually, Cao Cao knows very well that Sanma is probably Sima Yi and his two sons, and one trough is Cao Cao. This really happened in real history, and the Cao family was really usurped by Sima Jia!
