Liu Suwen, a top modern obstetrician and gynecologist, once traveled through time and became the daughter-in-law of the same name who was abandoned by her husband's family on the grounds of "infertility" in ancient times. The original owner was a midwife with a notorious reputation and was shunned by everyone. Faced with a desperate situation, Liu Suwen picked up his old profession, and with medical knowledge and surgical skills that were far ahead of the times, he started the road to become the "Master of Obstetrics and Gynecology" in ancient times. She broke the feudal superstition, improved the delivery method, saved the mother from the dead situation of "one corpse and two lives", and identified the illness from the rumors of "evil possession". Every rejuvenation is a resounding counterattack against the idea that a woman's lack of talent is a virtue. The highlight of the plot is that the heroine never relies on men and uses professional skills as her only weapon to fight for women's reproductive rights and life rights in an ancient society full of prejudice and frame-up. She eventually establishes the first "maternity hospital" in ancient times, trains countless female doctors, and gains an evenly matched and pure love with Shen Yanqing, an upright historian who records all her miracles.
