This battle has long surpassed many levels, ordinary masters can't clearly see the two exchanging blows, as if they're watching a slideshow, changing images every now and then, yet they can hear the sounds; Satan's beast-like roars, Li Yifei's sharp cries, and the thundering sounds of their destructive clashes, sometimes even comparable to thunder and lightning.
After Satan's second berserk transformation, he completely lost his sanity, Li Yifei felt like he was fighting a beast, but even a beast retains some rationality, while Satan had none, only knowing to attack, becoming even more tirelessly relentless.
"Roar!" Satan bellowed, his body just kicked several meters away by Li Yifei, but without pause, he charged again, like a black lightning bolt, smashing towards Li Yifei, and just then, a flash crossed the sky, a lightning bolt, both a black and white lightning bolt simultaneously crashed down toward Li Yifei.
