Don tried to cultivate once more. Closing his eyes, the surroundings dimmed. Qi, like fireflies, appeared and was drawn toward him. Yet, the moment he attempted to inhale them, a wave of fatigue washed over his body.
Confused, he opened his eyes, scratching his head.
"What's the matter?" a voice startled him. Turning toward the sound, he saw his Master staring at him.
"M-Master," Don hesitated. "It's just that… I tried the Simple Breathing Technique in my mind and succeeded after the first circulation. But when I tried another circulation, I felt extreme fatigue that prevented me from inhaling the Qi."
"Oh?" Apollo raised an eyebrow. That can't be. This is only a basic technique; why is he having a hard time? he thought. "Do it again."
"Okay," Don nodded. Following the order, he attempted to cultivate again. But, as expected, the Qi refused to enter his mouth or nose, as though he were out of air.
