Lin Chen, 24 years old, is a recent graduate and the only grandson of a retired master of cultural relic restoration in the Forbidden City. The beginning is at rock bottom: the century-old antique shop left behind by my grandfather after his death is coveted by the best relatives, and he is burdened with a loan shark of 500,000 yuan. His girlfriend of 3 years has cheated on a rich second generation, and he is publicly humiliated and wants to sell off his grandfather's belongings. His character is tolerant and has a bottom line, he is patriotic and loyal, and he is decisive in killing after awakening the system. He does not deceive laymen when appraising treasures, and he does not deceive collectors. He specializes in cracking down on counterfeiters and profiteers, fighting smugglers, and chasing lost national treasures. He has grown step by step from a desperate college student to a guardian of China's national treasures and a national-level treasure appraisal male god.
