Ruan Mianmian, a liberal arts genius who transmigrated, feigned idiocy for fifteen years in the Zhenguo General's Mansion—where everyone is a martial arts prodigy—to avoid practicing martial arts. When the Ruan family was framed by Prime Minister Xie Chongshan for colluding with the enemy and treason, at the moment of life and death she cast aside her disguise, exposing false evidence and sniffing out the traitor with her skills in ancient text textual research and document authenticity verification. In the face of crisis, she temporarily acted as a military strategist to gather criminal evidence, toppled the powerful treacherous official above the golden palace, and cleared her family's wrongful grievances. Once the wrongful case was settled, she enjoyed the full pampering of her family, yet fell deeply into the sweet trouble of being urged by the whole family to practice martial arts.
