It was practically equivalent to a second-level fire wizard wielding Corrupted Holy Flame.
All second-level fire spells differed only in form and method of eruption. As long as it had seen them before, it could imitate them.
Although the Inverse Holy Judger had no way to witness real fire magic, Yang Mu had. He not only knew their casting forms, but also their principles. After a thorough infusion of knowledge, Yang Mu gained a second-level wizard capable of using Corrupted Holy Flame.
Although the Inverse Holy Judger could not use magic items and had no spellbook, possessing only the basic casting ability of a second-level fire wizard was already terrifying.

What was more, it was merely a Necromancer's servant. Working with the other Undead Servants, even twenty second-level life forms would be burned into a pile of decayed bones.
Yang Mu's modifications were not yet complete. After setting aside one Second-Order Fishman corpse, he began modifying the remaining four corpses.
He still used various materials to first process the corpses. Yang Mu had no template for his modifications; the undead he created were determined by the materials he had on hand.
Several days later, four corpses lay within the Undead Refinement Array. Octopus tentacles grew from their backs, serrated teeth covered the ends of those tentacles, their bodies no longer fully resembled Fishmen, and strange seals covered them from head to toe.
Yang Mu did not actually recognize the runes on their bodies. They were not runes of the Mage World, but ones he had discovered within Fishman
