In April 290 AD, on the eve of Sima Yan's death. The time traveler Lin Han, 31 years old, male, is a teaching assistant at a university and a PhD candidate in the history department. His research direction is the history of the Wei, Jin, Southern and Northern Dynasties. He knew the historical details of this period very well - how Jia Nanfeng launched the coup, how the Eight Kings took turns on stage, how Yang Jun was executed - he could list them all with his eyes closed. But fate played a huge joke on him: he traveled through time and became Sima Zhong, who had been ridiculed for thousands of years as the "idiot emperor" in history.
Sima Zhong himself has no merit. He is too mediocre to be on the stage, and so stupid that the allusion of "why not eat minced meat" can be engraved in the history books, which is unbearable to look at. But the history that traveler Lin Han holds in his mind is like opening up a "God's perspective" to this broken world in advance. Faced with these comeback historical figures, you can't be stupid, but you can't appear too smart either. Once you are smart, Sima Zhong will wake up and change. The vicious eyes of Jia Nanfeng, Yang Jun, and the clan kings will immediately realize that something is wrong, and then your life will be over. Therefore, we must "pretend to be stupid" and bear the burden of humiliation, and plan step by step to "overestimate our capabilities" to fight for the highest power. It's not because he wants to become an emperor, but because all the forces around him want to trample him under their feet and crush him to death. If he doesn't move away, he will never be able to stand up.
