During the Jingkang period of the Dasheng Dynasty, in the abandoned Prince Rong's Mansion, Liu Yiyi, the former brocade weaving official, lived in seclusion here, guarding the lost "Yun Brocade" technique. Prince Rong's Mansion was included in the scope of demolition. Liu Yiyi ran around to save the brocade workshop, and unexpectedly met Shen Yan, the head of the household department in charge of the project. Shen Yan was attracted by Yun brocade skills and helped her apply to the court for intangible cultural heritage protection. During the process, the two discovered clues to the treasures of the previous dynasty hidden underground in Prince Rong's Mansion, and worked together to thwart the tomb robbers' conspiracy, allowing Yun Brocade's skills to be revealed again.
