Turmoil in the Base

As soon as the breach was opened, the defenses in other areas almost became useless, as a large number of zombies poured in through the breach, forcing Ma Quan to dispatch most of his soldiers to support this area.

"Where are the artillery units? Bombard them... quickly!" Ma Quan shouted desperately. But within just a few minutes, the front line of soldiers could no longer hold out, and many zombies surged forward, resulting in casualties.

"Boom, boom, boom..." Several shells exploded at the breach, successfully killing a large number of zombies. However, before anyone could rejoice, two dark figures charged out from the thick smoke of the explosion.

"Mutant zombies..." several soldiers shouted, their voices filled with fear. It was a consensus among everyone that mutant zombies couldn't be killed by ordinary weapons.
