The mute girl Bai Jin bloodbathed seven sects in one night. The whole city was silent, except for the bloody plum blossoms blooming on the sword's edge. She is not a madman, she is an accusation written with her life after her voice was taken away from the world. The young master of Yunxiao, Yu Zhao, was ordered to hunt her down, but under her silent blade, he saw clearly that the righteous path he guarded had long since decayed. Liu Wuyin, a remnant of the Medicine Valley, hides the truth. The demon sect Chi Ling wants to use her to subvert the world, and the mute boy Ari always follows behind her. The nursery rhyme he hums is the only echo on the night when the family was exterminated.
