When the "Iron Chain of the Finger" binding was completed, the Mirror Princess had already suffered a 9% loss in Health Points!
A total of seventy-eight Federal Watchers, whose firepower far surpassed that of the magicians—but that was only in terms of firepower. If one considered Defense, Evasion, and Survival Abilities, they were merely cannon fodder in this boss battle.
Thanks to the power of modern military arms, Ren Suo knew that the duration of the battle would be significantly shortened, meaning that the margin for error increased.
The attack mode of the Mirror Princess was already disclosed to Caroline and others, who commanded the Watchers to continually stay behind the Mirror Princess, while at this time the black-haired magician was quickly dealing with the dwarves together with Red Hood.
