Su Watang was carried into the coffin as the yin wife. She was supposed to be a sacrifice, but she opened her eyes in the coffin - she heard thousands of people kneeling and worshiping, and Xie Wujiu knelt down and called her 'master'. She doesn't know who she is, she only knows that the underworld is waiting for her return, Liu Yanniang seduces her into a demon in her dream, and Bai Qiye lays a bloody net waiting for her to fall into the trap. The mute slave carrying the coffin was carving her way home with blood and tears. She is no one's wife, she is the Lord of the Underworld who has been forgotten for thousands of years, and the Hades Palace should have been her home.
