The protagonist, Shen Yuan, is the only descendant of the declining soul cultivation sect. In the beginning, he was framed by the so-called upright sect as a demon who sacrificed blood to the common people because of his practice of the soul cultivation method that was despised by the world. He was brutally hunted and the sect was destroyed. In a desperate situation, Shen Yuan did not get any golden finger from the system or the old man. Instead, he relied on his profound understanding of the "soul" that was far beyond ordinary people and embarked on a unique path of cultivation.
Others' practice is to absorb the spiritual energy of heaven and earth, while Shen Yuan's practice is to "listen" and "control" the remaining souls. He can absorb the fighting instincts of veterans from hundreds of battles from the remnants of battlefield ruins, understand lost elixir recipes from the soul fragments of alchemy masters, and even piece together heaven-shaking magical powers from the place where ancient gods and demons fell.
The main plot revolves around the protagonist's "clearing the stigma" and "exploring the truth". He escaped all the way, becoming stronger along the way, constantly using the secret techniques of the soul to defeat the weak and the strong, and toy with the enemies who were chasing him. In the process, he discovered that behind the Righteous Alliance that was chasing him, there was a shocking conspiracy hidden - the so-called Righteous Leader was secretly collecting the souls of all spirits with the intention of refining evil weapons and subverting the order of the entire world of cultivation. The protagonist will eventually grow from a "devil" who is hunted by the world to a supreme master who reveals the truth, reestablishes the soul path, and is respected by all souls.
