The true eldest miss of the Liu family, Liu He'an, was framed by the fake eldest miss, Liu Yuwan, for stealing a hairpin and was abandoned in a dilapidated, deserted courtyard. Frail yet proficient in agronomy, she awakened the family heritage protection system, struggling to survive with three vegetable seeds and half a section of sweet potato vine. Facing relentless persecution from the Liu family—such as destroying fields, swapping for bad seeds, cutting off water, stealing crops, and arson—Liu He'an relied on her farming skills and evidence to strike back time and again, uniting with villagers to reclaim the deserted courtyard's land. She cultivated precious fragrant rice, weathered droughts and seed-seizing storms, and produced the ledger left by her biological mother to clear her grievances. Ultimately, witnessed by officials, the fragrant rice was officially named Deserted Courtyard Fragrant Rice, the villains were punished, and Liu He'an and the villagers protected the crop seeds they depended on for survival.
