Chen Yuan traveled to the antique market in 2005 and used the knowledge of later generations to pick up leaks in Panjiayuan. He accidentally discovered clues to Emperor Jianwen who had been missing for six hundred years from a Yuan blue and white porcelain vase. Peking University graduate student Su Tang met him in order to track down his father's whereabouts. The two went from distrusting each other to working together to decipher the secret. When Zhao Henian, Xu Zhiyi, Zhou Dalei and other forces were involved, Chen Yuancai discovered that he had become a core chess piece in the game between the archaeological community and the underground black market. And a code word from Aunt Shen, the sweeper's aunt, leads the truth to a shocking secret - someone doesn't want the end of Emperor Jianwen to be found.
