An SOP leaked from the dark web made prostitution and whoring a standardized process. Zero contact, platform-based, cross-border - the crime has been completed before the police can react. Criminals use Bitcoin to receive payments, use virtual locations to disguise themselves, and use encrypted chats to issue instructions. Policewoman Lin Xi was forced from a technical police officer to become half a hacker: Bitcoin tracking, dark web penetration, and tracing a transfer record to Southeast Asia. She thought she was chasing a shadow. Until the person codenamed "Lord Buddha" sent a message: "You are better than your father."
