Although it is a time-travel novel, it is written more based on the actual situation at the time. The choices made by the protagonist are also in line with the background of the times. No matter how awesome a person is in time-travel, he cannot build an airplane or a cannon.
Luo Chen, a mentally ill patient, traveled through time and became the newly succeeded Chongzhen Emperor Zhu Youjian. Due to his mental illness, Luo Chen would fall ill every time he tried to change the course of history. Then Zhu Youjian came online. Because Zhu Youjian was self-willed, suspicious, jealous, and eager for quick success, Luo Chen made crazy remedies in the front, while Zhu Youjian made crazy troubles in the back. Under such circumstances, can Luo Chen change the fate of Chongzhen and save the Ming Dynasty?
