The Apothecary Diaries Vol 5 and 11 Manga

Brand new. Please see picture.

Vol 5 Forced to leave the Inner Palace, Maomao finds herself in the employ of Jinshi! Immune to his charms, Maomao sets about learning the ways of life in the Outer Palace, where government officials and military officers go about the daily business of running the country.
Far from being fearful of her new surroundings, however, Maomao has her insatiable curiosity piqued by the soldier-occupied eastern wing, where she's been forbidden to go but where it seems further mysteries await...

Vol 11 Summoned to attend the Emperor on an evening jaunt to an ancient shrine that functions as a rite of passage for the rulers of the land, Maomao makes quick work of the puzzle inside, acquitting herself with aplomb. Having learned more about the Imperial bloodline than a commoner has any right to know, Maomao returns to her post at the Jade Palace. But her aim to stay out of the business of her betters is foiled once again when the Empress Dowager comes calling!
