After his father's funeral, Lin Chu found a mysterious machine inscribed with "Historical Deduction System" in his old house, which actually dragged him into the Wujiang battlefield in the late Qin Dynasty. As soon as he crossed the border, he was almost beheaded by the furious Overlord with a sword. Only by relying on his father's last words, he narrowly escaped death and gained three days to defeat the enemy.
Back to reality, Lin Chu left a recording with that "nightmare". This simulator is far from a simple historical game. However, every disturbance in history is accompanied by cold warnings and realistic crises.
What puzzled him even more was the girl Su Xiaotang with complicated eyes who always appeared at critical moments. She seems to know everything, claiming to be an "observer" from the future, and warns him not to trust Aunt Chen, who takes care of him like a mother...
What kind of truth does the mysterious rune tattooed by his father on Lin Chu's arm, the resonance of Su Xiaotang's pain across time and space, and the prophecy in his father's notes "If the symbol reappears, Chu'er has awakened" point to?
When Xiang Yu's afterimage whispered "Jiangdong... Is still waiting" in reality, Lin Chu completely awakened. He is no longer a passive chess piece, but a chess player!
Using the strategy and "reality mapping" capabilities given by the simulator, he strategized at historical nodes such as Hongmen Banquet, Julu, and Gaixia, trying to find a way out for the Overlord...
This is a life and death game spanning two thousand years! Can Lin Chu reverse the inevitable defeat of Chu and Han within seventy-two hours and rewrite Xiang Yu's fate of committing suicide in Wujiang? Can Su Xiaotang's existence be protected and the truth about his father's death be revealed under the encirclement and suppression of the "Causal Correcter" and the obliteration order of the "Scavenger"?
