Lu Yan of Guanwe Tang, an antique shop with a long history, possesses an extraordinary talent for authenticating antiques. His discerning eyes can uncover the truth about artifacts spanning a thousand years. At an antique appraisal conference, Han Shichang, the museum director, sets a trap by forging a document claiming a voluntary donation. He intends to seize a one-of-a-kind sky-blue-glazed treasure hidden inside a battered black-glazed bowl and destroys the Catalog of Treasured Artifacts to cover up the truth. At the critical moment, Lu Yan takes the stage with irrefutable evidence, including charred fragments of a manuscript and a backup USB drive. Before a hall full of experts and media representatives, he dismantles the hidden compartment of the black-glazed bowl, reveals physical evidence of three concealed seams, publicly tears up the fraudulent donation agreement, and exposes Han Shichang's long-planned scheme to steal the treasure.
