Medical student Gu Muqing was working the night shift in the emergency room when she acquired yin and yang eyes in an accident and was forced to bind the yin system to become an intern. From then on, she followed the mysterious black-robed seducer Lin Xiuyuan to travel between the Yin and Yang realms, but found that Lin Xiuyuan would secretly tamper with the book of life and death every time he collected souls.
As Gu Muqing worked together to deal with strange deaths one after another, in the process of tracing the truth, she gradually uncovered a thousand-year-old secret: Heaven tried to tamper with the destiny of the world and robbed the special destiny by unfair means. And it was precisely in order to fight against this shocking conspiracy that Lin Xiuyuan did not hesitate to violate the laws of heaven and secretly collect specific fates.
In the ghost market, the underworld trial, and the duel between heaven and earth, the two went from testing each other to sharing life and death. Gu Muqing awakened the spiritual root of medicine, and Lin Xiuyuan exposed the secret identity of the immortal and demon. When the order of Yin and Yang faces collapse, can they use medical knowledge as an edge to rewrite the book of life and death and rewrite their destiny controlled by heaven?
