In his previous life, young painter Lin Wan stepped into the legendary ghost town Fengdu alone in search of his missing sister Lin Zhixia. She naively believed in the seemingly kind innkeeper and local squire, but she didn't know that she had stepped into a carefully crafted trap. She was coveted because of her "Yin constitution", and was eventually sacrificed to a Yin traitor disguised as Hei Wuchang by so-called "good Samaritans" in her old house behind a famous mountain in Fengdu. Her soul was ripped away and annihilated in endless pain and regret. She never got to see her sister again until her death. She only remembered the proud smiles of those betrayers and the cold chains of hypocrisy.
When she opened her eyes again, Lin Wan found that she was reborn three years ago, when her sister had just disappeared and she decided to leave for Fengdu on the eve. The memory of her tragic death in her previous life is unforgettable. Those hypocritical faces, sinister calculations, and inhuman pain completely transformed her from an innocent painter into a scheming avenger. In this life, she is no longer a lamb to be slaughtered. With a foreknowledge of the future, she once again set foot on the land of Fengdu, but her goal was completely different: not only to rescue her sister, but also to make all the accomplices in the world who participated in the persecution and the hypocritical usurper pay a hundredfold price!
Fengdu is a tourist attraction on the surface, but in fact it follows the ancient taboo of "yang during the day and overcast at night". Once the midnight hour passes, half of the city will turn into a "yin city" where no living person can approach, with ghosts patrolling the streets and wandering souls. Relying on her past life memories, Lin Wan accurately avoided the initial trap and took the initiative to move into the century-old haunted house - Qingluoju - that was destined to become the center of the incident. Here, she met Chen Yan, a descendant of the tomb keeper with a cold appearance and mysterious life experience.
