Accidentally borrowing the body of a descendant to return to the Meng family, she opens a pawnshop, completing her evaluation while investigating bizarre occurrences plaguing the Meng family one after another. Yet three special men successively seek her out: Xie Lin, who bears an unusual destiny; Ji Zhansheng, a top-tier fox demon hiding secrets; and Wen Yuyan, who has been entangled with her across a hundred years from her past life. As the three ingredients gradually gather, Meng Changpei's lost memories begin to awaken, and what truly awaits her is an old game spanning a century.
