Modern history enthusiast Ying Yuan traveled through time and became the Qin Emperor in a different world. The court was filled with treacherous ministers such as Qin Hui and Cai Jing, and the Chu army was suppressing the country outside. After being bound to the system, he needed to subjugate his country or die in order to cultivate immortality and live forever, so he deliberately acted like a foolish emperor. Unexpectedly, all his foolish moves were misinterpreted by the ministers as the policies of a wise emperor. The treacherous ministers "whitewashed" their allegiance, and the Qin Dynasty grew stronger. In the ridiculous "reverse governance", Ying Yuan saw what the people wanted, and finally put aside his obsession with cultivating immortals, shouldered the responsibility of the emperor, and determined to protect the peace of the world.
