Maomao investigates the clinic of the rear palace and uncovers connections between Shenlü, an experienced court lady, and the dissemination of knowledge about abortifacients, which were previously used for attacks. Meanwhile, her adoptive father Luomen, back in the palace as a physician, supports Gyokuyou's pregnancy and reforms medical practices through educational writings. His past as an exiled luminary is addressed, while rumors about his role in historical scandals begin to surface.

Meanwhile, the political situation escalates: Suirei, the assassin believed to be dead, kidnaps Shisui and forces Maomao to cooperate in order to obtain the recipe for a "revival drug." At the same time, the cunning grand commander Lakan confronts the powerful Lord Shishou with evidence of his involvement in the assassination attempt on Jinshi using Feifa firearms. The episode ends with a dramatic showdown in the clinic, where Suirei forces Maomao to flee the palace—while Lakan and Shishou's power games destabilize imperial politics.
