Time gradually passed, and the massive armies of humans and zombies were nearing the three great mountain ranges of the Northwest. Shaun, with a calm demeanor yet eyes filled with killing intent, led the way. Due to the presence of seven hundred million elite zombies, their marching speed wasn't very fast. Today, the dense sea of corpses finally reached the vicinity of the mountain ranges.
Shaun stood in the air, eyes slightly narrowed. His enhanced vision allowed him to easily observe the movements in the Northwest Mountains. Countless mutant beasts were arranged in formations, gathering at the outskirts of the mountain ranges. They stood motionless but with fierce light in their eyes.
Above in the sky, numerous mutant birds hovered, forming a dark canopy that shrouded the heavens. In the distant mountains, countless more mutant beasts were hidden.
