This is a world of ruins from the mythical age. After the ancient war between gods and demons, the gods retreated and the wilderness was broken into "Kyushu". Practitioners improve their realm by understanding the remaining miracles (the fragments of mountains and seas), trying to reproduce the power of the ancient gods.
The practice system is based on the Classic of Mountains and Seas, with a total of nine heavens: the realm of resting soil (building foundation and cultivating the essence), the realm of spiritual aperture (opening up the sea of consciousness), the realm of butterfly transformation (transformation of the soul), the realm of divine treasure (uncovering the bloodline of the ancient gods in the body), the realm of breaking the void (tearing the space, comprehending the law), the realm of the holy realm (the realm is self-contained), the supreme realm (Kyushu dominates), the realm of Shinto (half-step ancient god), the realm of wilderness (reshaping the divine realm)
The "Orthodox Sect" pursues order and tries to suppress the ancient chaos; while the "Ancient Legacy" wants to revive chaos, leading to a crisis of annihilation. Lin Yun carries the secret of the two worlds and struggles with his fate.
