Before the Purple-Eyed Demon Overlord could attack the Quicksand Tower's leader, Dedale swung his huge metal staff and released over a hundred orange Bursting Flames, which exploded in front of the Purple-Eyed Demon Overlord's body. The terrifying explosive force made the Purple-Eyed Demon Overlord shiver, and the Abyssal Power covering his body turned into black smoke that kept dissipating.
The Demon Overlord kept roaring. Space seemed to tear as his claws sliced, but after slicing in front of him, he discovered that his surroundings had suddenly turned dark, as if he had been shrouded with curtains. And not only was the light covered, but mana fluctuations had also dissipated.
Dylas was continuously pouring mana into the Dark Night Cloak on the other side of the Curtain of Darkness.
