('If I'm able to use a breathing technique to get rid of the air resistance, then that would be perfect. But really, the only way to get rid of air resistance is to get rid of the air or get rid of the laws of physics,') Rui sighed.
The latter was out of the question. Although Martial Artists seemed like they broke the laws of physics on Earth, it had become clear to Rui that this was not the case. Just that the laws of physics had an additional element beyond what he just knew that allowed Martial Artists to perform ridiculously superhuman feats without breaking the laws of physics.
Not even Martial Artists violated the laws of physics, and not even Martial Artists could warp reality. At least, none that he had ever seen thus far were capable of such feats.
