Livestream antiques appraiser Qin Zhaoye was banned after exposing a counterfeit goods network. But then he unexpectedly heard a broken bronze jue speak and learned that the missing national treasure, the Nine Provinces Casket, had resurfaced. To clear his name, he teams up with the poker-faced conservator Su Jianwei to relaunch an underground livestream, using the language of artifacts to uncover the memories of cultural relics. Veteran appraiser Tang Henian provides clues from old cases, while criminal investigator Huo Qingluo keeps a close eye on their every move. Their nemesis Xu Guanchao and the mysterious auctioneer Jiang Tingyun have also set their sights on the same national treasure.
