That life is not this life... Under the mask of the popular campus king Lu Xian is a cold-blooded, extreme, possessive, acknowledging death and extremely world-weary person. However, one day, he was confessed in a normal way, rejected others in a normal way, and the mask he had maintained since childhood was torn apart by the other party. On a confused and depressing night, he accidentally broke into the dead man's laboratory and was struck by the laser emitted by an undeveloped mysterious instrument. From then on, he traveled back to ancient times.
Lu Xian, who was born into a famous family of killers and was completely liberated, committed murder at the age of three and became an idiot at the age of five, madly seeking revenge on all mankind. Finally, at the age of nine, he got tired of it, so he challenged Tianliuyuan and wanted to leave the family. After being seriously injured, she went down the stream and was rescued by Qin Longling, the "ghost doctor with a thousand faces" who happened to be passing by. She lived an ordinary life ever since.
