In Zhonghai City in 2015, antique restorer Zheng Chen discovered the treasure appraisal formula of "distinguishing color and broken patterns" in the broken ancient books left by his father. Combined with modern instrument testing, he gradually formed a unique cultural relic appraisal system. At the same time, China Overseas Auction House is preparing for an auction of national treasure-level cultural relics called "Treasures of Mountains and Rivers". Among them, the Shang Dynasty bronze tripod "Fang Ding with Black Bird Pattern" is listed as the finale. Little did they know that this cultural relic was the key evidence lost in the "12.7 Cultural Relics Theft Case" twelve years ago, and Zheng Chen's father was the main suspect in the case that year.
