Lin Xiaolu, a college student, went back to the Northeast for a funeral and discovered that there was another hidden reason behind his grandmother's death - the body held snake scales in its hands, its eyes were gouged out, and there was a weird smile on the corner of its mouth. On the night of the wake, the "White Immortal" hedgehog in the family of the Five Immortals suddenly warned: "Your grandma paid off the debt for others, and now it's your turn."
That night, she was raped by the Snake Immortal Qingyao and forced to become a disciple. However, as she investigates a series of supernatural cases, she discovers that each of the deceased is related to an evil cult sacrifice twenty years ago - those children born on the fifth day of May were all made into "yin boys."
What is even more terrifying is the "dragon fetus" that appears inexplicably in her belly, the silver bracelet on her wrist that is exactly the same as her grandma's, and the chain scars on Qingyao's body that are engraved with dates...
All clues point to the truth - she was the chosen sacrifice.
