Humans are inherently born with five hundred more years of Dao practice than spirit monsters, which means that a spirit monster cultivates, its primordial spirit reincarnating repeatedly, and it takes five hundred years to reincarnate as a human.
Reaching this step, reversing the path to become an immortal, the distance to longevity is still elusive.
Therefore, in ancient times, many spirit monsters sought shortcuts, directly attempting primordial spirit possession to occupy human bodies.
That is what demons are.
To act abnormally is to be a demon, to act against reason is to be human.
"It's impossible for spirit monsters to transform into humans by themselves... those who refine horses and worship the Immortal Family eventually end up being possessed by a human body, unable to even be human in the end." Old Yu said lightly.
