A startling glimpse of the milk tea shop allowed Lin Xiaowan, who has yin and yang eyes, to break through the strange black shadow that sucks yang energy, and also made her fate unexpectedly intertwined with the mysterious assistant Chen Yang. Bizarre disappearances occur one after another on campus. The victims are as shriveled as firewood. The remaining black energy and the strange patterns of the full-moon night point to a dusty taboo secret.

The evil formations he has set up, the puppetry technique to control people's hearts, and the black lines spreading on his left hand all hide the conspiracy of devouring the essence of living beings. Lin Xiaowan relies on her ancestral traditional Chinese medicine acupuncture and perfumery skills, and Chen Yang uses talisman techniques to learn about the hidden master's past. The two went from testing each other to fighting side by side.

They must use needles as blades, incense as shields, and talismans as sharp edges. In the mist where humans and ghosts intertwine, they must prevent the completion of the forbidden technique and fight against the undying dark obsession. And the hot energy remaining in the compass fragments indicates that this showdown between good and evil is far from over...
