Arthur who was swinging his dagger upwards against the waterfall was now slowly understanding how to release his mana outward. Yet despite feeling a tiny bit of joy about it, he couldn't celebrate as he was still being continuously flooded by the waterfall. It has been a few hours since the beginning of his training and he was finally feeling the accumulated fatigue.
His master Ren might've healed his wounds, but the energy that was drained wasn't returning and at this moment he was truly exhausted. He could feel his body creaking from the stress of his movements. He was losing steam and it was right when he was nearly able to cut the waterfall in half.
'Am I going to fail just like that?... No, I won't fail, never again!' Arthur started to think harder to find a solution to his current problem.
