"System: Congratulations, you have broken through to the lower realm of 5th Grade!"
Wain collapsed onto the dungeon floor, his body drenched in sweat. His chest heaved as he gasped for air.
"I made it," he whispered, a tired but triumphant smile on his face.
It had taken him two whole days, but he'd finally broken through. The chaos mana in the dungeon had been unbelievably beneficial for him. It wasn't something just anyone could use due to its corrosive effects, but for those who could endure it, it was the perfect type of mana.
"5th grade," Wain murmured to himself, smiling again. He'd reached this level once before through his Shadow form, but now, achieving it as himself felt entirely different. It was clearer, more solid, and powerful in a way he hadn't fully grasped before. Now he understood why the 5th grade was considered the first major breaking point.
It was all about mana fusion.
