Bobby inspected the rest of the slips of paper and found that the majority consisted of offensive skills. Out of the 20 holy martial arts, there were only two body-strengthening techniques, including the Silver Wall Technique. "The hardest skills to learn are most likely offensive and speed skills," Bobby thought. Inside the dimension of his left eye, he recalled the mysterious wind palm and the four incomplete holy martial arts: Wind Flowing Stance, Tornado Partial Wind Stance, and Burning Wind Slice. Those skills alone would require a lot of time to learn, so Bobby decided to choose the Silver Wall Technique.
