The "Seven-Pointed Star Serial Murder Case" lasted for ten years. The murderer committed the seven crimes every seven years in the order of "Gluttony, Greed, Arrogance, Envy, Sloth, Rage, and Lust." There were three cases in 2013, three cases in 2020, and the final chapter in 2027. Blood-painted seven-pointed stars and encrypted death notices were left at all crime scenes, and the nails of the deceased must contain funeral parlor-specific preservatives (pointing to Huo Ci's father), pocket watch gear oil stains (pointing to Shen Yanbing's father's repair shop), and lipstick fragments (pointing to the death scene of Xu Chaomu's sister).
