The mighty force of the Heavenly Fiendish Energy ceaselessly surged into Xu Ping'an's body.
This overwhelming Heavenly Fiendish Energy constantly transformed into extremely dense True Yuan.
As the True Yuan continuously thickened, Xu Ping'an's cultivation also kept on improving.
Very soon, Xu Ping'an broke through to the Sixth Rank Second Layer Realm.
Gu Lingyan's face was full of surprise; she had never imagined that the man before her could actually absorb the Heavenly Fiendish Energy for cultivation.
This was the Heavenly Fiendish Energy!
This fellow could actually absorb it?
Wasn't this too inconceivable?
Xu Ping'an, however, didn't pay attention to Gu Lingyan's surprised gaze, but instead coldly huffed, "Operate your cultivation technique and expel this Heavenly Fiendish Energy from your internal organs. Find a way to suppress it in your Pill Sea."
