I became a maid of the insane poison and hidden weapons clan, the Sichuan Tang Clan. One day I woke up inside a martial arts novel—as a cleaning maid (세답 시비) of the Sichuan Tang Clan, the family of poison and hidden weapons! I thought I was just a low-level servant, but this body seems unusual. From Tang Zhong, the Tang Clan’s Grand Elder and rejuvenated old master known as the Poison King, to Namgung Hui, the young master of the Namgung family—I keep catching the attention of the novel’s main characters, making my days anything but peaceful. “Sohye, listen carefully to what I say. I’m serious about teaching you.” Eventually, I become Tang Zhong’s disciple in a maid’s body and begin learning both literature and martial arts… Can I survive safely in this dangerous martial world?
