A jade gambling master was framed and betrayed in his past life, leading to the ruin of his family. Reborn back to the village in the year 2000, in order to save his young daughter, he acquires an illustrated system capable of identifying raw stones, yet gradually discovers hidden dangers lurking within the system. Following the clues, he investigates and realizes this is a trap set by his rival. Guided by those around him, he makes the painful choice to discard the system, relying on his two lifetimes of accumulated jade-appraisal skills to gather evidence. After several rounds of showdowns, he successfully brings down his rival, and his daughter smoothly recovers. He opens a jade appraisal school to impart his craft, leading the villagers toward shared prosperity and completing his self-redemption.
