"You truly have a keen eye!" Robin pointed toward her with a playful grin and a lighthearted chuckle. "But no, you're mistaken. I sacrificed twenty levels to save you. My purification process, in comparison, was far easier~"
Well… easier in terms of requirements, not the process itself.
For the reality was that Robin had literally set himself ablaze, letting flames surge through every vein, every nerve, until they devoured and burned away every trace of impurity or corruption lodged within his body and soul.
Those flames were merciless. If they had caught someone from the Durghren race, for example, they would not have gone out until the victim was completely consumed, either dead or remade into a pure-blooded human. That was the true ferocity and relentlessness of those purgatory fires, the reason he never uses them, afraid that the would attack him for any impurity he doesn't even know about!
