In Episode 19 of "The Apothecary Diaries," a series of mysterious events unfolds, prompting Maomao to uncover a potentially deadly conspiracy. It begins when Lihaku informs Maomao about a fire at a warehouse, which was meant to cover up the theft of ceremonial tools, hinting at a deeper intrigue connected to the recent misfortune of the warehouse managers and a strange gift from a high-ranking court lady. This revelation leads Maomao to draw a connection between the incidents she has been investigating, and she suspects a link to Suirei.

When she shares her suspicions with Jinshi, he suggests that the incidents might be part of a series of traps. Jinshi’s promise of a rare medical reward spurs Maomao to investigate further. She consults the archives, where the demoted administrator provides insight into the ceremonies department and expresses concern about a structurally questionable pillar in the ceremonial hall.

As the ceremony begins, Maomao concludes that an attack on the event might be imminent. Despite her low status, she rushes to prevent the disaster but is stopped and attacked by a guard. Her persistence, however, catches the attention of Lakan, who appears behind her and grants her access to the hall. At the same time, Maomao refuses to look back to see who it is, even though she knows the answer and doesn’t want to owe this person a favor.

In a dramatic turn, Maomao saves Jinshi from a collapsing pillar, revealing his noble lineage and calling into question his identity as a mere eunuch administrator. In the process, she is injured and faints in Jinshi’s arms. The episode ends with Jinshi carrying Maomao for medical treatment while all the priests and others in the temple bow before him. Perhaps it should also be noted that Jinshi wears a robe with a golden emblem during this ceremony, displaying the dragon (symbol of the emperor) and the phoenix (symbol of the empress). This outwardly presents him (presumably) as a member of the imperial family, even if it isn’t explicitly explained to the viewer.
