Deep inside the palace, she hid her talents and relied on her medical skills to work at the bottom: detoxifying strange poisons for disgraced concubines, treating old injuries for young eunuchs, and quietly weaving a fine network of connections. Until he met the powerful eunuch Xiao Heng by chance - this man was deeply trusted by the emperor and was in charge of the palace supervisor, but he always covered his face with a cold mask. His fingertips always carried a faint scent of ambergris, and his eyes hid a sharpness and gloominess that was inconsistent with his status as a eunuch.
The first encounter between the two was an accident: Ruan Mianmian bumped into Xiao Heng dealing with "traitors" and was almost silenced, but was temporarily able to survive because of the words "This poison can only be cured by the Ruan family's medical skills"; the second meeting was a trial: Xiao Heng used her medical skills to investigate the "ghost case" in the Queen's Palace, and she used his power to find her father's old subordinates; when they finally became allies, they realized that they both had obsessions - Xiao Heng was originally the son of a general, but his family was framed by Queen Liu's natal family. He castrated himself and entered the palace just for revenge. The "evidence of collaboration with the enemy" that Ruan Mianmian is looking for is closely related to Xiao Heng's enemies, the Liu family and the Li family (the prime ministers of the dynasty).
From then on, she served as a bait in the harem, luring the concubines to fight and exposed clues; he served as a sword in the court, using the power of eunuchs to contain powerful officials. But when the hatred deepens, love also secretly arises: when she is being made things difficult by the queen, he will calmly hand over the token to save his life; when he is seriously injured by the assassin, she will risk her death and use forbidden magic to survive. It's just that the identities of eunuch and palace maid, the hatred and the shackles of power, make this relationship destined to be stained with blood and tears.
