After receiving a report late at night, detective Shen Mu arrived at the scene, only to find a headless female body and a strange note.
There were no fingerprints, no surveillance, and no witnesses at the scene. All evidence seemed to have been wiped away by invisible hands.
When he was about to announce the unsolved case, the head of the deceased appeared out of thin air on the bedside of his bedroom, smiling strangely at him.
Shen Mu realized with horror that the murderer was not a "human".
And on the back of the note, there were words in blood that only he could see: "Next, it's the turn of the person you care about most."
