Mo Wenwen seems to be a winner in life: she is beautiful, recognized as the campus beauty in the university, and is the center of attention wherever she goes.
But no one knew that she had a horrifying secret: she had to go back to her hometown in the mountains once a month, drink a bowl of weird black soup prepared by her grandma, and add a drop of her own blood into the seeping black jar under the bed.
Gradually, she discovered that the people around her who bullied and pestered her began to have bad luck one after another. They were either seriously ill or had accidents. They were very evil. At the same time, a transfer student Yin Qingyan, who is too handsome to be true, suddenly appears. His eyes are cold, but he always appears mysteriously when she is in danger.
Mo Wenwen finally realized that there was definitely something wrong with grandma and that black jar! She was forced to start learning the strange voodoo skills inherited from her family, but found that her body had also undergone terrible changes...
On one side is the pure campus life, on the other side is the evil world of voodoo; on the other side is the cold and mysterious "human voodoo snake" Yin Qingyan who protects her, and on the other side are the evil forces from all sides that are eyeing her.
Mo Wenwen was forced to embark on a road of no return. She must uncover the mystery of her life experience, control the powerful power in her body, survive the crisis, and eventually become the femme fatale who can both bewitch all living beings and protect her loved ones.
