In the past, righteous cultivators felt disdain whenever they mentioned ghostly cultivators.
Beast Tamers absorbed the spiritual energy of nature, but ghostly cultivators refined the undead, so they thought that they were superior to ghostly cultivators.
The living looked down on the dead. The Beast Tamers generally thought that the undead who lingered in the world and refused to reincarnate were evil demons, but they had forgotten that every undead was once their closest kin. Perhaps after they died, they would become a member of the undead.
To be honest, no one was nobler than the other.
Then, why didn't they like ghostly cultivators?
Did they think that the ghostly cultivators were evil villains just because they seemed creepy?
