On the night when she was pushed into the ancient well by her tribe, Shen Zhaoyue should have died out of resentment, but instead she became the master of the evil ghost Yin Jiuyuan. From then on, she was surrounded by a dark wind, and every step was filled with ghosts, but no one dared to kill her - because whoever touched her would die. Bai Suni presses forward step by step in the name of redemption, Zhou Manniang protects the truth with silence, and Xie Yunzhou's bell is breaking Yin Jiuyuan's sanity. When Tong Xiaohuai's blood stained the stone walls of the ancient well, Shen Zhaoyue realized that she was not the chosen sacrifice, but the key to being imprisoned for hundreds of years. And Yin Jiuyuan's love is poison and the only way to survive.
Shen Zhaoyue was forced to walk between the Yang world and the Yin world. In order to find a way to survive, she had to rely on the power of Yin Jiuyuan, but every time she used it, she was one step closer to completely turning into a ghost.

Xie Yunzhou finally recalled his past life - he was the executioner who was ordered to kill the princess, but at the last moment he blocked the thunder for her, locked up with his soul, and was trapped in reincarnation forever.

Shen Zhaoyue found a skeleton exactly like her own deep in the ancient well, holding an unsigned letter in her hand: "If you become a ghost, there will be no life in the world; if you become a human, I will be destroyed forever."
