Built around the concept of a “multilayered universe,” the story develops a complete progression system spanning the Mortal Realm → Cultivation Realm → Spirit Realm → Immortal Realm → Divine Realm:
- Mortal Realm: Ordinary regimes such as the Great Yin Dynasty. Spiritual energy is scarce, and this is where the protagonist begins;
- Cultivation Realm: Sects such as the Azure Cloud Sect stand alongside one another, with spiritual veins converging here. It is the primary stage for cultivation;
- Spirit Realm, Immortal Realm, and Divine Realm: Each is a higher dimension of energy, with increasingly strict laws and power systems that grow exponentially stronger. They conceal ultimate secrets such as the “Origin of Purity and Turbidity” and the “Shadow of Chaos.”
- Cultivation levels: The story strictly follows a “slow-burn growth” approach, progressing from Mortal → Qi Guidance → Foundation Establishment → Golden Core → Nascent Soul → Deification (Cultivation Realm) → Spirit Emperor → Spirit Venerable (Spirit Realm) → Immortal King → Immortal Emperor (Immortal Realm) → Divine Venerable → God Emperor (Divine Realm). Each level is divided into early, middle, late, and peak stages, and breakthroughs require unique trials such as “tempering with impure spiritual energy” and “comprehending the laws”
- Protagonist Kou Shen: He has a turbid spiritual root and a turbid physique. On the surface, he is a “taboo good-for-nothing,” but in truth he can devour and transform spiritual energy of all kinds, including the five elements, yin energy, and death energy. His cultivation is extremely slow, but his foundations are solid and his potential boundless. He is the embodiment of the “Origin of Chaos”;
- Heroine Xu Lu: She has an immortal spiritual root, a pure root rarely seen in ten thousand years, and is naturally attuned to the spiritual energy of heaven and earth. Her cultivation speed defies the heavens, forming a central bond with Kou Shen built on their “opposition and complementarity as purity and turbidity.”
