Su Wantang enters the Marquis Manor as a concubine, changing her destiny due to the awakening of the life-replacement contract. When someone maliciously harms her, it rebounds upon the person they cherish most; with sincere compensation, debts can also be repaired. Using the rules of debt reversal to strike back, she reclaims her belongings, traces the old military provisions case with her mother's jade seal, uncovers the deficit black market of the marquis manor, the inner palace, and the imperial court, and finally breaks free from her status, establishing the Women's Household Department to help women win back justice and freedom.
