Wei Fuyi, the last descendant of the coffin-carrying family passed down from generation to generation, was discriminated against because of her identity as a woman. During a ceremony to "warm the coffin" of a noble person, she was plotted and was treated as a living sacrifice and buried with the coffin. After relying on her family's secret skills to escape from a desperate situation, she discovered that she could clearly see the resentful souls in the world. From then on, during the day, she was a mysterious coffin carrier who walked between the yin and yang worlds, guiding the dead and resolving misfortunes for the living; at night, she transformed into a murderer, using her ability to "see ghosts" to solve weird and unsolved cases that the government was helpless to solve. From the "Water Ghost Seduction" case in a rural town, to the shocking "Painted Skin Bride" case in the capital, to the "General Evil" case in the depths of the palace, Wei Fuyi used the body of a woman to do shocking things, slapping all kinds of monsters, ghosts, snakes, gods and those who despised her. She and Xie Zhixing, a selfless young minister of Dali Temple who only believed in the law, had never known each other before. From mutual suspicion to working together, they jointly uncovered a shocking conspiracy that used countless innocent souls as sacrifices in an attempt to overthrow the dynasty.
