1. The surface world (human world): similar to the early Republic of China or ancient times, with normal mortals, warriors, and righteous monks. People follow ancient customs and taboos because if they violate them, they may be targeted by "dirty people".
2. The inner world (uncanny realm/delusion): When certain conditions are met (such as looking in the mirror at midnight, paper figures looking back on rainy days, abandoned ancient houses), people will fall into a strange and bizarre space. The logic here breaks down, the laws of physics fail, and it is filled with indescribable "gods" and "ghosts."
3. Power system - [Fate Mark]: Everyone has innate fate marks in their body. Ordinary people's life marks are locked, but monks open them through practicing skills. But every time you open the life mark, you may be contaminated by the strange gods of the "other world". This is both a strength and a curse.
4. Core conflict: In ancient times, the gods fell, and their remains and wills were scattered in the world, forming a strange "loophole in the rules." What the protagonist has to do is to find the truth before being swallowed up by these rules.
