The Phantom Game

Twelve years ago, a global brain competition called "Tianyan" suddenly ended, with all participants losing their memories and the only known champion, "Zero," vanishing without a trace. Twelve years later, a down-and-out math prodigy, Lu Chen, receives a blackmail letter containing a formula he has never seen but written in his own handwriting—a formula pointing to the coordinates of a new tournament. He is forced into "The Phantom Game": a dark web intelligence duel with no rules, no limits, and life-or-death stakes. Each round is a logical dead end, with opponents including a psychology authority, a cryptography genius, a memory manipulator, and a behavior-predicting AI. Win, and you get a piece of sealed memory; lose, and your brain is permanently formatted. Lu Chen soon discovers that all opponents' ultimate goal points to the same missing person: Zero. And he himself may be the "counter-kill piece" set by Zero.
