The heart of the human defense effort against the monsters was undoubtedly the blast zone.
A one-kilometer expanse meticulously engineered to unleash havoc and shatter anything or anyone brave enough to venture within its bounds.
The first time that Rocky witnessed it in action, he realized just how formidable the zone was as within seconds it decimated thousands of undead skeletons.
Arrows, mortar, spells, bombs, heavy artillery.
Every form of long range AOE attack was all concentrated in one stretch of land, obliterating any army brave enough to walk into it.
From the first wave of opponents, not a single undead skeleton was able to cross even half-way through the blast zone, as within seconds, the undead were reduced to a pile of bones and ashes.
"Alright, hold your fire-" Paladin Patrik commanded, as the archers and mages in his unit paused their fire when it seemed like the enemy was completely decimated.
