In the end, Hua Qingyi chose the most inconspicuous place on the left. There was nothing there, and the surroundings were quite empty. He swung the octopus hook and flew toward the gap on the top of the wall. Once he landed smoothly, he tested its bearing strength. Only after ensuring it was secure did he begin to slowly inch his way up.
The right-angle climb was a tiring position. Hua Qingyi pushed off with his feet and grabbed the rope with one hand to pull himself up half a notch, then repeated the method to move upward. He felt this would be faster than climbing straight up the edge, though if he failed to grab the rope at the same moment, he would fall, risking at best injury or worse, disability. It was only once he reached the top that he realized how dangerous the task was, spurring his fear and apprehension after the fact.
