Ten Miles Sword God
No not grandpa, his wife Quiong. Follow. The primordial sprit is in her currently, 10 years remember. Now let's flash to the future past. Chen Fan was a weak cultivator when she Quiong was killed protecting him. She then passes the spirit to him but she was the primordial spirit Quiong died when it invaded her on earth. Currently, she is the primordial spirit of the fiend God and he has a sliver of it in him. Ephinay!!!!!
Whoa. Cooll plot point development. Someone he knows was taken over by the Fiend. Im putting money on his Grandpa. They really over developed his relationship with him, even moreso than with the mother and father. and they cant kill his wife and have her be taken over lol, besides she was the grand opportunity so she already has her plot cover.
