"Hehehe…" A wild grin emerged on Senior Zenshin's face. "Not so slick after all."
Rui had to admit that he had earned that boast. It was an incredibly powerful technique that did not send an attack traveling like how it was before. Instead, he had caused attacks to appear on their location.
That was incredibly impressive.
Of course, now that he had seen it, he had instantly figured out how it worked. It actually did not work by generating sharp shockwaves, instead, it worked on a principle of imbalance of pressure.
He generated a tremendous amount of pressure on a target with his breathing technique, then used his claw swipes to generate an extremely thin slit of vacuum amidst that pressure. The rest of the body of the target was experiencing immense pressure, pressure that had nowhere to go until he created a tiny slit of vacuum on his target's flesh with his claws, giving that vacuum a place to push through due to the zero pressure outside that area.
