Amidst the undulating dunes, a group of aliens were frantically attacking a barrier. Sparks flew in all directions and ripples appeared on the barrier's surface, but it seemed that the aliens' attacks hadn't yet reached the defensive limit of the array.
Boom~
A lightning bolt, as thick as a bucket, plummeted from the sky and blew a Demi-God Level alien, who was fiercely attacking the barrier, to pieces. The aliens around it were all startled and immediately scrambled to the side, leaving a large empty space.
"Continue!"
A gloomy voice came from behind, causing the aliens to shudder. The next moment, as if a switch had been flipped, they began attacking the barrier with renewed frenzy.
