Antiquities restorer Chen Zhaoye discovered during the live broadcast that he could hear the last strong emotion left by the old objects. He relied on his incomplete voice to see through fakes and scams, but gradually discovered that each seemingly independent commission was completing a piece of artificially chopped testimony for Warehouse No. 7 In May this year. Chen Zhaoye discovered during the live treasure appraisal that old materials that had actually experienced the incident would leave only one sentence of voice. He and investigative reporter Cen Wu started from an original tape hidden in the interlayer of a high-imitation bronze mirror to trace the "seven-yard cabinet", the disappearance of Cen Wu's father, and the chain of interests that can remotely control the spread of evidence. Each unit of old objects not only delivers a treasure appraisal and ability reward, but also gradually forces the two people to decide which evidence should be disclosed and which people must be protected. When the clues in front of him gradually point to the same truth, Chen Zhaoye must find his own answer between price and choice. This is an urban suspense novel driven by specific events, character relationships and long-term foreshadowing.
