Book of Nightmares

A strange and absurd world. The two realms of yin and yang collided with each other, and the nightmares in the yang world turned into ghosts in the underworld. The vengeful ghosts killed the humans in the yang world. The lair of evil spirits, the dreams of evil spirits, things that have happened and things that have never happened, all appear in this era. This is a world where life and death, dreams and reality, interact and merge.
