Son of the Vile-Emperor
He has the hobby of collecting dead bodies. His own body was an amalgamation of body parts from various cultivators. His left arm was created from the Arch-Ancestor.
His body was destroyed and his soul was taken by MC in (Chapter 1192) so that he can torture him.
He put his soul into a puppet body and made the him dance madly for nine days. At that point, the puppet body continued to dance, but his soul was almost completely faded away. He almost had no self-awareness left. On the tenth day… he danced into death, and his soul dispersed.
