The story takes place in the world of immortality where luck and the laws of language are intertwined. The protagonist, Lan Tianhua, is the daughter of a family of dynasty luthiers. She was relegated to the countryside due to her family's involvement in political strife. Only after she was in her sixties did she get the opportunity to "cleanse away the dust" and enter Taoism with the guqin passed down by her family. She uses music to communicate between heaven and earth, and plays the "Requiem" specifically for the souls of the dead, washing away their resentments, thereby accumulating merit and slowly cultivating "sword bones". While washing the wronged soul of a general, she accidentally touched the projection of the "Broken String of Destiny" and glimpsed the truth of a tampered history. This also attracted the first enemy - "self" who comes from the future and tries to maintain the established history. In the process of avoiding pursuit and exploring the truth, Lan Tianhua met Yun Wujiu, a businessman with the "Pixiu Juyun Bloodline" but suffered from backlash, and Mo Xuan, a talisman master with a withdrawn personality who studied the "Void Crack Path". Together, they were involved in a catastrophe caused by the resurrection of the ancient beast "Yin Yang Rebellion Taotie", and found that many old monsters trapped in the bottleneck were frantically competing for treasures that could reverse their luck. In the end, Lan Tianhua used the rhythm to repeat and break the strings, and in the realm of "wordless origin", he understood clearly that true "immortality" does not mean changing the past or solidifying the future, but accepting all causes and effects, using the current "cognitive evolution" to transcend the constraints of linear time, and attaining the "Xuanxuan Sword Bone" at the place where the music is silent, becoming a "living history" and "tuner" walking in the world.
