Lin Fan just ignored him and continued punching at each of the beasts that charged at him.
However, Fei Jun already realized that Lin Fan was a threat, so he no longer sent the beasts he controlled at Lin Fan. Instead, he gave them the order to run from Lin Fan, to get as far away as possible from him.

He himself wasn't a powerful expert and he didn't have any powerful beasts that he controlled. The only thing that was supporting him was this bead that he had been given by the lord and the beasts that he stole with the bead.
