In ancient times, a meteorite encased an extraterrestrial object and descended upon Fengzi Ridge, bringing with it seven mysterious creatures. These creatures could parasitize humans, interfere with their consciousness, and lead them to commit evil deeds. An ancient virtuous master and his disciples crafted seven wooden tablets from a sacred tree, drawing the alien entities into them and naming them the "Seven Heart Tablets". They then forged a Phoenix Lock from the meteorite to seal the tablets. Throughout generations, skilled and noble individuals inherited the master's mission, recording the methods of sealing the Heart Tablets and passing them down through the ages. A hundred years ago, a dog accidentally dug up one of the wooden tablets in Fengzi Ridge, bringing the Heart Tablets back into the world. Over the next twenty years, a series of bizarre murders occurred one after another. Five ordinary but passionate young people — Mu Dai, Luo Ren, Yan Hong Sha, Wan San, and Cao Yan Hua formed the "Phoenix Squad" by fate, embarking on a perilous adventure to subdue the deadly tablets.
