Capítulo 712: Idea

Rui's eyes glinted as a germ of an idea formed in his head.

('Being able to alter the speed of sound waves through the air and surpass the speed of sound… There are applications of this beyond just creating speedy projectiles that move many times the speed of sound,') Rui realized.

In fact, the increased speed of the projectile was actually just the simplest of applications.

('The constant speed of the Sonic Bullets was shackling, but with this technique, there are routes that I can consider that I couldn't before,') Rui noted.

With sound projectiles of much higher speed, the execution of the Pathfinder technique became much easier since the sound bullet traveled to its target much faster and thus took less time to reach its target.
