After a car accident, modern female academic prodigy Jiang Zhen time-travels along with four underachieving classmates. She is reduced to a butcher's daughter, suffering disdain and suppression from her top-scholar husband Yu Zhao and his co-wife. Facing adversity, Jiang Zhen uses modern knowledge to establish a paper mill, breaking the monopoly of aristocratic families, and adopts a pseudonym as a great scholar to pioneer the compilation of works by women. Meanwhile, she rallies her fellow time-traveling classmates, acting as their brain trust to help them gain a foothold and build a power moat. At the New Year's Eve banquet, she uses modern optical and chemical knowledge to create miracles and cure the empress. Ultimately, facing a coup, Jiang Zhen tosses out an imperial divorce decree to cast him aside, beginning a wonderful life from then on.
