When Rocky, donned in his Void Magic Armor, became a phantom of the battlefield, not only did he wreak havoc but he was also brimming with confidence. However, the overall situation on the battlefield was far from as favorable as he imagined; in fact, "not optimistic" would be a more accurate description.
Not every soldier on the battlefield wore Void Magic Armor!
Those without Void Magic Armor were as fragile as paper in front of the Demons, only managing to hold off a Demon when several soldiers worked together.
Especially when the fight turned into a melee, once the frontline troops and the wings inevitably engaged in hand-to-hand combat with the Demons, the advantage of the Demons became markedly evident. Not to mention the troops from Backhill Village, even the Guard Corps equipped with rune equipment also fell into a tough fight.
