The story takes place in the world of immortality shrouded by the tree of memory and governed by chess rules. The 49-year-old protagonist Lu Yelei is regarded as a weirdo by ordinary people because he is born with a "nihilistic heart" and cannot feel any emotions. By chance, he triggered the "Innate Bagua Diagram" inherited from his family and was forced to embark on the path of cultivating immortality. In the process of pursuing "feelings", he practiced the "Time Reverse Sutra" and "Yin Yang Liangyang Mysterious Technique". In the "Forgotten Root" area of the Tree of Memory, he met Zhu Yin, a demon girl with the "bloodline of Qiongqi Disaster", and encountered "Zhen Nian Zhenren", the leader of the demon slayer who advocated slaying demons. As his cultivation improves, Lu Yelei gradually becomes involved in the grand conflict between the ownership of the Tree of Memory and the rules of the chess universe: the demon slayer wants to purify the Tree of Memory, the demon clan vows to protect the foundation of survival, and the guide in the world of mortals constantly questions the meaning of his practice. When Lu Yelei was in the "Heart Lotus Blooming" state, he discovered the prototype of the "All Things Return to Ruins Pattern" in his Tao Heart. Finally, at the place where memory originates, he faces the ultimate choice: should he merge with the origin of memory and become the eternal master, or should his broken Taoist heart return to the mortal world and experience the short-term reality? He chose the third path - to reconstruct the tree of memory and the rules of chess in the realm of "eternal freedom", allowing all living beings to freely define their own existence and memory, and he himself became the "anchor of memorylessness" that maintained the new balance. In the eternal silence, for the first time, he "feeled" the endless rhythm of all things.
