Jiang Xiaoman time-travels to Da Qi and becomes a rough-work maid in the General's Mansion. Utilizing her pediatric nutrition and medicated diet knowledge, she saves the endlessly crying Xuan Ge'er and gradually gains Shen Lingshuang's trust. She identifies the assassination schemes of the wet nurse and concubines, resolves multiple crises, and uses medicated meat jerky to help break through the border siege. To protect more children, she and Shen Lingshuang establish the Baiqiao Mother and Baby Food Workshop, promoting complementary feeding and orphan-nurturing initiatives. Facing clan property seizures and frame-ups by the Eldest Princess's faction, she handles them with evidence and rules. Eventually, she is appointed as the Imperial Dietary Official, and her recipes are published across the realm to protect more infants.
