Shen Yi, a doctor of history, was working overtime to proofread the manuscript of the Ming Dynasty. He traveled back in time and became the Chongzhen Emperor who had just ascended the throne and suffered from insomnia all night when Wei Zhongxian presented his beautiful maids. Using the Internet-connected mobile phone he carried with him, the first thing he searched was not the strategy of governing the country, but "When will the Qing Dynasty perish?" When he saw the number "1911", his back went cold, and he was determined not only to save the country, but also to personally cut off the law of historical cycles.
