Kai looked up at the cloudless sky, the sun blazing down on his face as he lay flat on the ground, panting heavily. He had just run ten laps around the training camp, and his body was screaming for a break. Yet, his mind was clear and determined. He knew he had to push harder, to become stronger. The smell of freshly cut grass filled his nose as he took a deep breath, trying to ignore the burning sensation in his lungs.
He glanced over at Erik, who was already on his twelfth lap, his muscles rippling with each stride, his eyes locked onto the horizon. Kai's anger boiled at the sight of his rival's seemingly effortless endurance. It wasn't fair that Erik had been born with such a high power level, while he was stuck at the bottom, struggling to keep up. But the system had made it clear: if he followed its instructions, he could change his fate. And so, he pushed himself up and started jogging again, his legs feeling like lead.
