The old Taoist finally regained his composure.
He stared at Ren Feifan and asked, "Have you ever been to the Raging Fire Sect of the Outer Hidden Sect before? And when did you learn the Sunset Inferno?"
This was the only explanation!
He would rather die than believe that the kid learned it on the spot!
It's very likely that he was a disciple from the Raging Fire Sect of the Outer Hidden Sect.
The opponent's cultivation was at the Earth-level Realm, which was about the same as a disciple there.
Ren Feifan was completely baffled when he heard about the Raging Fire Sect.
He hadn't even been to the Outer Hidden Sect, so how could he possibly have gone to the Raging Fire Sect to learn martial arts techniques?
He helplessly touched his nose and honestly said, "Senior, I have no idea what you're talking about. I just observed your battle and learned from it earlier. Is there a problem?"
Upon hearing this, the old Taoist wished he could smack this cocky guy's head.
