Xitian (Lingshan): It is not a paradise, but a crack in the real dimension, connecting the chaos of outer space. It was not the Buddha who lived there, but an ancient being known as the "Indescribable Perfect One."
Scripture: records forbidden knowledge that can distort reality and summon ancient gods. Mortals will go crazy when they hear it, and only those who have a special physique (abnormality) can bear it.
Cannibalism: In this world, cannibalism is not only for immortality, but also to suppress the collapse of one's own body by devouring the sanity (SAN value) of the same kind.
Heaven: The huge mechanical biological fortress suspended in the stratosphere has long been dominated by ruthless order. It tries to block "madness" with "reason", but it has long been decayed internally.
