In essence, neither path was wrong. In comprehending the way that the rock withstood wind, there was naturally much to ponder, it was just that the creator of the technique, although understanding both aspects, had a forthright personality and didn't like hiding away, instead choosing to face things head on. Of course, one could argue that no matter if it was running away to find a weak point, or standing behind a rock, both were methods of hiding, but…
Well, the creator of the technique would disagree, and they were a mighty Spiritual Palace level expert, so who could really argue against them? In any case, in their words, standing behind the rock was still charging forward into the battlefield, it was simply finding the core of the field and taking advantage of it. After all, only an idiot would charge into attacks, right?
