Tang Yuheng has been outstanding since she was a child, until a car accident turned her into a non-human and ghostly existence at the age of sixteen. She signed a contract with the underworld using her identity as a black account that does not exist in the book of life and death, and walked around the world as an underworld agent, dealing with supernatural events that the underworld could not take care of. She originally thought that she could be reincarnated if she accumulated enough virtues, but Tang Yuheng met her second-rate partner when she was an intern as a forensic doctor. From then on, she struggled with one thing every day. Should she beat Qin Lisheng to death, or should she beat Qin Lisheng to death.
