Transmigrated as the Marquis's Wet Nurse

[Transmigrate into a book + raise a child and turn the tables] Qin Zuiman, a library study addict, opens her eyes to find herself a widowed wet nurse in the countryside. Her rundown house leaks, a baby cries in her arms, and her mother-in-law is gravely ill. With no way to make ends meet, she is forced to apply for a wet-nurse job at the Marquis's estate, where her modern childcare knowledge amazes everyone!

She knows how to burp babies after feeding, treat heat rash, introduce early learning and solid foods, and prevent smallpox. The legitimate son grows plump and healthy under her care, the marquis's wife treats her as a trusted confidante, and even the aloof illegitimate son sees her in a new light.

When her three-year contract ends, she leaves with her reward money and opens the first “daycare” in the ancient world. Raising children, running a school, writing books, fighting epidemics... She rises from a lowly wet nurse to the renowned “Benefactor Lin.”

But the former prefect, who resigned from office for her and is content to work as her bookkeeper, keeps asking her by lamplight, “Madam Lin, are you still in need of a husband?”
