In the year 2850, Chen Xiao, the youngest strategic scientist in the Earth Federation, activates the last “causality” time machine amid the ruins of World War III. His mission is not to save the future, for the future is already a wasteland. His goal is to return to the singular point of civilization's history and set things right from the source.
When his consciousness awakens again, he finds himself held between two eunuchs, kneeling on the cold brick floor of Xianyang Palace. A soft, effeminate voice reaches his ears: “Your Majesty, Li Si and Zhao Gao have submitted the ‘edict of guilt’ against Prince Fusu...”
Chen Xiao's consciousness merges with the body of the King of Qin. He snaps open his eyes, fixing a keen, unfamiliar gaze on the stooped Zhao Gao before him. At this moment, the soul of a man from more than two thousand years in the future takes over the historical emperor, a tyrant whose final years were marked by misery.
He has inherited not only the King's power, but also the knowledge accumulated across two thousand years of human civilization. His task is not to cultivate himself and put his household in order. He will use this identity to reshape the fate of human civilization.
