The world is divided into three planes: the human world, the spiritual world and the fairy world. The human world lacks spiritual energy and is a gathering place for mortals and low-level monks. The spiritual world is full of spiritual energy and has rich resources for cultivating immortals. It is a training place for high-level monks. The fairy world is a legendary existence, and only ascended immortals can enter it. This world is highly hierarchical, with the weak eating the strong, monsters and gods, and various dangerous places and secret realms, which contain treasures and opportunities, but are also accompanied by huge dangers.
