Su, a modern-day working woman, unexpectedly travels back in time to an ancient rural household. She finds herself facing a difficult situation: her elders are sick and frail, her younger siblings are still children, and the family is burdened with debt. After awakening a money-making system, she relies on her intelligence and hard work to earn her first fortune by gathering mountain produce and trading medicinal herbs. Decisive and fearless, she takes on unruly neighbors and fiercely protects her family, gradually winning her younger siblings' hearts with her sincerity. She then buys farmland, introduces specialty vegetables, and joins forces with a major restaurant to make a fortune every day. From a household with nothing to her name, she builds a grand brick house, ensures her family can enjoy meat at every meal, and embarks on a journey to find her missing relatives. Watch how this eldest sister turns her entire family’s fortunes around through her own efforts and builds an increasingly prosperous life for them all.
