She could hear the color of the voice. Dark red is fear, gold is protection, and cyan is traces of memory tampering. Delivery boy Zhang Chi jumped from the 32nd floor after taking orders for seven days. Surveillance and suicide notes all pointed to suicide.

When the information "Auction of Lin Ting's Problem Sex" appeared on the dark web, she was left with only one question: Who am I?
