An SOP leaked from the dark web turned prostitution into a standardized process. No contact, platform-based, cross-border: before the police could react, the crime was already complete. The criminals took payment in Bitcoin, disguised their locations with virtual positioning, and issued instructions through encrypted chats. Lin Xi, a police officer with a technical specialty, was forced to become half a hacker: tracking Bitcoin, infiltrating the dark web, following a single transaction all the way to Southeast Asia. She thought she was chasing a shadow. Until someone codenamed Buddha sent her a message: “You’re better than your dad.” (All criminal methods in this story are presented to expose and warn against them. Do not imitate them. This story is entirely fictional.)
