Chen Yuan, a modern history student, triggered a "loophole in the law of heaven" by excessively deducing Liu Bang's life, and was forcibly bound to the "Gaozu Correction System". He traveled to three key time and space in the late Qin and early Han Dynasties (before the defeat of Pengcheng, the battle for the abolition of Chu, and the siege of Baideng). As Liu Bang, he completed the task of "avoiding strategic mistakes, balancing the power structure, and breaking through historical dilemmas." Finally, he exposed the truth about the system's attempt to obliterate "human variables" and completed self-salvation in correcting history.
