At the end of the Eastern Han dynasty, during the upheaval at the Luoyang palace, the warlord Cao Cao arrives in the hall of reincarnation, only to stumble upon a horrifying truth: Sima Yi has joined forces with the lingering souls of Zhuge Liang and Zhou Yu to sign the “Luo River Pact.” Using “the Three Kingdoms returning to Jin” as bait, their scheme triggers a chain reaction of collapse: the Five Barbarians' uprising begins early, Mongol cavalry sweeps across Europe and Asia, and the entropy of the universe surges! The System is furious: “Sima Yi is a contaminant in the timeline. Send a restorer to take control of key events. As for you, Cao Cao, your obsession is too strong, so you are forbidden from returning to your original timeline. You will be forcibly reincarnated in a parallel world to fill the vacancy!”
In this life, Sima Yi strikes first, cutting through time and seizing Cao Cao's body. Under the name “Emperor Wu of Wei,” he begins his plot to usurp the Han dynasty by “holding the emperor hostage to command the warlords.” Meanwhile, the forcibly reincarnated Cao Cao's soul is shoved into the body of Liu Bei, a man who weaves mats and sells shoes. From then on, Liu Bei becomes a vessel for two souls: his surface consciousness is the benevolent, weak-willed Uncle Liu, while within him lurks the ruthless, decisive Cao Mengde!
It's a reversal and fits the history, very interesting.
