In a world where rank is determined by voice and the Zhengyin Platform controls the realm, Jiang Zhengsheng, a mute disciple who has been silent for three years, is forced to speak for the first time. A single word "retreat" collapses half a courtyard wall; a single sentence "kneel" makes the Zhengyin envoy drop to his knees on the street. From then on, he transforms from a neglected mute into the "monster voice" that the Zhengyin Platform must eliminate. To protect the Zhengqi Martial Arts Hall and investigate the buried false-pronunciation old case from seventeen years ago, Jiang Zhengsheng, along with Hall Master Zhou Yan, Niu Zhuang, and collating female official Su Shiyi, tracks down the remaining scores and exposes lies all the way, facing Jiang Wujiu, the national preceptor who controls imperial power. When the truth is completely uncovered in the Hall of Supreme Harmony, Jiang Zhengsheng's single word "awake" calls back the controlled emperor.
