Shen Qingzhu, the "ghost-hand midwife" in the capital, set a rule of "not accepting orders from the Hou Mansion" because her grandmother was framed to death by the Hou Mansion. However, she broke her rule due to the news that Su Wantang, the young lady of the Hou Mansion (the child her grandmother had saved back then) had a difficult delivery. She entered the Hou Mansion with the ancestral "rebirth technique" and "birth-promoting soup" and found that the young lady was "contracted" by Zhou Yurong, the mistress of the Hou family. While Shen Qingzhu used professional techniques to stabilize the young lady's life, she secretly investigated and collected evidence of Zhou Yurong's poisoning in order to seize the throne. Shen Qingzhu finally successfully delivered the baby, exposed the evil deeds of the Hou family to the public, and cleared her grandmother's grievances.
