At the very instant Argentum went ahead and took a step inside the Inferno Plains, what greeted him first and foremost was the intense heat that circulated around the area. In an instant, Argentum felt like he was being burned alive, with every subsequent move he made hastening this burning feeling.
Concurrent to the burning feeling he felt was great pain. It was a type of pain that did not just stop at the outer layers of his body, but even the insides of his body were not spared from this body. If he were to gauge the level of pain he was feeling right now, then it was close to the peak, only being beaten by the pain he felt from being hit by a red lightning bolt. And that was just the first red lightning bolt he had to withstand.
