Rivalry

Training field.

Dudian was standing in an inverted frog posture. The fingers of his left hand gentle rubbed the sand on ground. Although he couldn't percieve the sensations from his left arm but he could visually grasp them. He would use his fingers and feel the movement through his eyes. Although the effects of such an observation didn't bring a result but it was much better than blindly continuing to exercise.

The hardest problem that he faced in the absence of perception was that he couldn't determine the state of his own arm. He could even feel a punch or hit. The only option was to rely on visual aids. But how could he watch enemy's action and look after his left arm if he was on a battlefield? How could he have spare time to pay attention to his arm? Therefore he had to exercise so much that he would feel the activities of his left arm on instinct.

Time passed.
