Fu Jingchen is an apprentice at a small jade shop. Calm, composed, and meticulous, he sticks to his principles and hones his jade-working skills day after day, all for a quiet life. But a conspiracy shatters that peace. The owner of an underground casino sets him up, tricking his father into owing a massive gambling debt, then threatens his father's life to force Fu Jingchen to repay it by a deadline. With nowhere left to turn, Fu Jingchen unexpectedly awakens a golden finger: X-ray vision that lets him see inside jade. Determined to save his father and clear the debt, he steps into the world of jade gambling. Starting with the most basic raw-stone stalls, he uses his vision and keen mind to see through worthless-stone traps time and again, uncovering high-ice and glass-grade jadeite in astonishing reversals. He steadily builds his wealth and makes a rapid comeback, not only paying off every debt but also gradually exposing the casino boss's schemes and serving him his own medicine as he brings the villain to justice. In the end, Fu Jingchen uses his exceptional eye and skill to rise beyond his apprentice status, build a jade business empire of his own, and become a legend in the city's jade trade.
