Time dimension: After the ancient era was broken, the laws of heaven and earth were incomplete, and practitioners needed to find the complete Tao in the "Ruin Realm" (the secret realm where the law fragments condensed).
Spatial structure: The Nine Heavens Realm is split by the cracks in the Ruins Realm. Mortals in the Lower Three Realms struggle to survive. There are many sects in the Middle Three Realms. The hidden ancient clans in the Upper Three Realms control the secrets of heaven.
Core Conflict: The ancient prophecy mentions that "the reborn person of the Tao Fruit" will reshape the law, and various forces have launched a thousand-year game around this.
