An immense horde of undead monsters surged out from the Fenglu Mountain ranges, and before the Fenglu Base could fully retract its defensive fortifications, they had already stormed into the battlefield.
This was a group of formidable monsters engulfed in the aura of death. Although they were also primarily composed of First Rank and Second Order rotting corpses, skeletons, and Skeleton Beasts, the unique atmosphere of the Domain of Death and the icy ghost aura fused with their bodies made them even more powerful.
The troops of Fenglu Base, battle-hardened, quickly responded to the sudden encounter, unleashing a barrage of intense gunfire to halt the assault of the undead horde.
The heavy artillery tore through the bodies of rotting corpses and skeletons, and even the tougher ones struggled to withstand such firepower.
