Chen Mu had run into trouble. The mid-grade second level of perceptual sensitivity training was going to be far more difficult than he had imagined. Across seven straight days, except for resting, he had been immersed in it to the point of even dropping the exercise gymnastics. He could already tell those were obviously providing less and less improvement.
He didn't find the training boring, even as tortuous as it always was. It was a lot more interesting than making one-star power cards. When he had been making those, especially at the beginning, the scale of the resistance he would encounter was something hard to believe. He was only 11 at the time, and that card master was someone in dire straits about to starve to death. He only had seven days of study.
