While investigating a bizarre unsolved case of the "Painted Skin Bride" in an ancient town, Shen Weixi accidentally entered a century-old house shrouded in a powerful barrier - the "Jin Garden". In order to avoid the evil spirits who were chasing her, she broke into a secret room full of talismans deep in the mansion. In desperation, she dyed a strange blank marriage certificate red with blood. In an instant, the color of the sky and the earth changed, the wind roared, and a cold and biting voice sounded in her mind:
> "The contract has been made, you are my wife. With your blood, call my name - Xiao Jin."
From then on, Shen Weixi was forced to enter into a "ghost marriage" with this mysterious being who was sealed deep in the ancient house. Not only does she have to face an endless stream of life-seeking ghosts and evil cultivators who covet her special physique, but she also has to carefully deal with the unstable temperament of her "husband". Xiao Jin's power protected her, but it also made her fall into a deeper whirlpool. They jointly tracked down the truth about the "Painted Skin Bride", but found that behind it was a shocking conspiracy against the lost gods, and a huge secret hidden in Shen Weixi's own bloodline. As they fought side by side and depended on each other for life and death, taboo feelings quietly grew. When the truth about Xiao Jin's seal, the betrayal thousands of years ago, and the root of Shen Weixi's fate gradually surfaced, they had to make a choice: should they work together to subvert the yin and yang order, or be separated again in the torrent of fate?
