Shen Zhiyao, an obstetrician who was demoted to the countryside, met Zhou Sui, a stubborn and conservative midwife. In a mountain village lacking medicine and equipment, she relied on the fusion of ancestral home remedies and modern medicine to snatch mothers and babies back from death time and time again. As forbidden herbs, silent girls, and hidden bamboo slips emerge one by one, the truth gradually emerges—this village has long been cursed by a midwifery accident thirty years ago. She is not here to save people, but to solve the mystery of the deepest doctor in this mountain cave.
