Behold the scion of the Poisoner-Physician lineage, possessed of dual mastery over the healing arts and venomous craft, who finds herself most unexpectedly cast into the ancient Eastern Qin Dynasty. There she awakens as Bai Heran, the ill-regarded legitimate daughter of the Wen Duke's household. Confronted by cruel circumstance—a mother cruelly slain, a father whose gaze passes over her with chilling indifference, a stepmother wielding domestic tyranny with iron resolve, and sisters whose honeyed words conceal viperous hearts—a burning resolve ignites within her breast. Thus does this wronged maiden pledge to grasp the quill of fate itself, and with indomitable spirit, rewrite the very ledger of her destiny.
