Xiao Tian, an autistic genius, possesses extraordinary logical deduction and memory abilities. The only person he trusts is his little brother Lin Yue. However, in order to monopolize a sum of underground black money, Lin Yue orchestrated a backstab - Xiao Tian's father was falsely accused and imprisoned, his mother died in a car accident, and Xiao Tian himself was framed as a murderer. During the escort, Xiao Tian fell into a deep cliff, and everyone thought he was dead. But he survived, and awakened Goldfinger's "causal deduction" - the ability to reversely deduce a complete criminal chain from any subtle clues. Three years later, Xiao Tian returned with a new identity. He is silent, cold, and uses suffocatingly precise methods to make every betrayer pay the price. And Lin Yue will experience firsthand what true despair is.
