Behind the battle lines, eight hundred soldiers removed the depleted High-Grade Magic Crystals and tossed them aside. They then took magic-filled High-Grade Magic Crystals from iron boxes nearby and fitted them into the slots.
The entire process took less than ten seconds, and the eight hundred modified Magic Energy Cannons were activated once more.
Within the undead army, the banshee Nadas watched the purple energy spheres soar into the sky but paid them no mind, continuing to order her troops forward.
The Death Qi that had accumulated over centuries was enough to withstand humanity's long-range attacks.
After eight volleys, the vanguard of the undead army was only three thousand meters from the front lines.
"Fire!"
At the command, over twenty thousand bowmen stood in neat ranks and drew feathered arrows from their quivers.
The arrow shafts were snow-white, while the arrowheads were engraved with dense miniature Magic Arrays that glimmered with a faint golden halo beneath the sunlight.
The instant they drew their bows and nocked their arrows, Battle Qi flowed from their fingertips into the arrow tails, activating the miniature Magic Arrays.
The hum of taut bowstrings joined together, echoing over the battlefield.
"Loose!"
In an instant, tens of thousands of arrows flew from their strings with piercing whistles, pouring down upon the undead army.
The dozens of miniature Magic Arrays on each arrow activated one after another, releasing the Dawn Power sealed within.
As they flew, they resonated with one another, increasing their power.
Death Qi surged madly, forming several gray-black barriers in an attempt to stop them.
Yet as the arrows descended, they easily pierced the gray-black barriers, their scorching hiss burning countless tiny holes through them.
The rain of arrows fell into the undead army, instantly erupting into dazzling bursts of golden light.
