In the near future, after a global "spiritual tsunami" event, the physical rules were partially distorted, and human collective subconsciousness (obsession, belief, fear) began to materialize and interfere with reality.
East: People have great feelings about cultivating immortals, heaven, underworld,
The belief in ancient gods and folklore (such as the "Red Ghost" and "Wong Tai Sin") has given rise to corresponding spiritual paths, gods and weirdnesses.
West: Belief in God, angels, demons, Cthulhu, and superheroes has formed power systems such as the Holy See, Demon Hunters, and Mysteries.
Japan: Fear and belief in eight million gods, monsters, and urban legends make the Night Parade of One Hundred Ghosts a reality.
The conflict between different belief systems; the conflict between human rationality and the irrational creations created by ourselves; and how to use or even manipulate these "obsessions" to gain power in this crazy world.
