At Qixia Ferry, birds are chirping in the middle of the night. Shen Qingdu, the daughter of a soul-crosser, was born with the ability to see monsters, but she didn't know that she had the "Seal of Half Soul" - every time she crosses a demon, her soul returns one point, which brings her one step closer to the truth.
Men in the city disappeared one after another, leaving only a strand of black hair on their pillow. After Shen Qingdu's investigation, he met the cold-faced demon-catching master Jiuyuan on a narrow road. She uses her "obsession to transform" to collect demons, while he takes "killing demons" as his mission. They have different ways of doing things, but they are forced to go together.
Thrush poison, mirage mirror, paper wedding dress... Behind every evil disaster is thousands of years of obsession, the greed of the human heart, and every self that "can't let go". And when the truth about the broken seal of Crying River emerged twenty years ago, Shen Qingdu and Fu Jiuyuan discovered that their life experiences were actually the last key to this conspiracy.
"When you cross demons, you also cross people. When you cross people, you finally cross yourself."
This is an entanglement between man and demon, and it is also a fateful love that spans thousands of years. Chinese-style monsters, unit investigation, two-way redemption. When the fog cleared, he stood in front of the Wangchuan Mirror, waiting for her to return from the water.
