Blood wolves were creatures of level twenty, like the five trolls, with the exception of Duo Sa, whose power had reached elite boss status. Yet, by worshipping the Book of the Abyss day and night, the trolls had unintentionally absorbed some Abyssal Power.
This power, visible as a grey aura constantly swirling around them, formed a layer of tough armor. The wolves' biting and clawing could not break it.
Simultaneously, the trolls' attacks were laced with the same grey energy. Once unleashed, this Abyssal Power could deal significant damage to the blood wolves. It granted the four trolls—each of equivalent strength to a level twenty creature—the power to crushing blood wolves of equal level.
Duo Sa, who already possessed the prowess of a level twenty boss, had grown even stronger, almost reaching the threshold of a level twenty lord. If allowed to continue worshipping, he would inevitably break through to become a level twenty lord—it was just a matter of time.
