It wasn't solely because of Zhou Wen's speed and agility that he managed to dodge the beams. It had to do with the Mutated Fairy's fingers drastically slowing down. The mark that Hui Haifeng's strike left on her hand continued to do its magic, slowing down her hands with time.
Furthermore, Zhou Wen didn't know if he was mistaken, but he felt that the Mutated Fairy's strength had weakened significantly. The intensity of the beam had clearly decreased.
By the time the Mutated Fairy attacked Zhou Wen, she was in a panic. Hui Haifeng took the opportunity to leap up and strike her back, bombarding her with his two fists. This produced about four marks on her back.
The Mutated Fairy turned around in an attempt to kill him, but her body suddenly stopped in midair. Jiang Yan had already landed on the ground at some point in time. He held onto the long whip with both hands and forcefully pulled back the Mutated Fairy's body, preventing her from continuing her flight.
