It was like trying to hit a live, unrestrained snake, and he was on a bucking bronco ride, but if he didn't at least try, it would get away, and would keep coming back. All he needed was to hit it hard enough to disrupt its concentration a bit, as he would just need one more hit after this one to shove the blade into its heart. He was being beaten against the ribs, he had a hunch he would always remember where the ribs where on a large dog sized white dragon for the rest of his life.
