Before her grandmother died, she repeatedly warned her, "Don't touch that bone comb." But at the bottom of a camphorwood chest in an antique shop, Lin Xia found the eerie object, with half a finger bone hidden inside. The moment its teeth cut her fingertip, a ghostly figure in an indigo cross-collar shirt appeared in the mirror. The sound of someone combing their hair at midnight and calls from a disconnected landline dragged her into a nightmare haunted by evil spirits.
At the critical moment, Shen Yan, heir to the Shen family's exorcist bloodline, burst through the door. A peachwood compass suppressed the evil, and yellow talismans burned away the vengeful spirits. The warmth of his palm did more than dispel the chill: it also revealed a bond between the Shen and Lin families spanning two generations. Shen Yan's grandfather had once made a promise to Lin Xia's grandaunt, but a disturbance in a place of ill omen left him with lifelong regrets.
A bizarre bronze mirror that devours shadows, an abandoned rouge workshop hiding embroidered souls, and a scheme behind shadow puppets that lure souls: danger followed close on the heels of danger. Su Qingyuan, a sharp-tongued but loyal exorcist, and Gu Xifeng, who seemed carefree but had another agenda, soon joined them. The four formed a temporary team and fought side by side in ancient towers and caves filled with yin energy.
The bone comb attracts evil spirits, and the paired pendants open the gates to the underworld. As the secrets of a long-buried blood sacrifice array are revealed and the conspiracy of the Rebirth Pawnshop comes to light, Lin Xia is no longer an ordinary girl anyone can prey on. With a bronze bell in hand and talisman papers glowing beneath her brush, she joins forces with Shen Yan, not only to fulfill their ancestors' regrets, but also to protect the love fate has destined for them.
