After surviving a brush with death, Liu Yueyue opens her eyes only to find her husband's family forcing her to leave with nothing. Facing a sharp-tongued, mean mother-in-law and an ungrateful scoundrel of a husband, she fires back fearlessly, securing half the shopfronts and fifteen taels of silver before decisively divorcing him and taking her two children with her. Back at her impoverished birth family, she must face mountains of unpaid grain debts and her sister-in-law's provocations. Fortunately, Heaven grants her an invisible space that can preserve and store goods and even multiply medicinal herbs. With her remarkable photographic memory and business acumen, she makes delicious food, gathers medicinal herbs, and opens an apothecary, steadily building her fortune. In this life, she vows never again to live at anyone else's mercy and to lead her family to a better life.
