Ironically, he figured out the mechanism and the principle of the technique of Project Keep Up With Kane earlier than he did the other projects despite focusing on it last.
('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.
Thus, for now, he could only think about the former.
('Getting rid of air in my path; in other words a vacuum,') Rui's eyes lit up. ('That's definitely quite practical in comparison. After all, all breathing animals do that to a certain extent.')
When inhaling, the part of the air closest to the nose or mouth would immediately be sucked in, and for just the briefest of moments, there would be a small vacuum or area with less air density before the atmosphere would refill the area and return it to normal air density.
That was the limit to what ordinary humans could do, but that limit was irrelevant to Martial Squires like Rui.
('Creating a vacuum before me would not only help with getting rid of air resistance, it would also accelerate me due to the pressure difference,')
The air was constantly exerting pressure in all directions, the reason it was rarely noticed was that the same air pushed back against itself in the opposite direction on the other side of the body, air on the opposite sides pushing against each other.
Yet what would happen if the air in front of Rui was removed, and only the air behind him was pushing him?
He would not only be unhampered by air but would also end up being accelerated by it.
('Brilliant! I have to start immediately,') Rui grew even more excited.
He needed to work out the mechanism that he would be using for the breathing technique.
Normally, he would need to purchase a technique from the Martial Union that possessed principles and mechanisms somewhat to what he was looking for, then master them and then finally adapt and change them to become a fit building block for his new technique.
This was time-consuming, he would also have to return to the Martial Union after just having returned from it.
Thankfully, he did not feel the need to do that this time.
He mastered many breathing techniques throughout the years. Harmonic Breathing, Final Breathing, Wind Breathing, and the breathing techniques used in Tempestuous Ripple technique he had mastered as a Martial Apprentice, the breathing mechanism in the Sonic Bullet technique as well as the Mighty Roar Flash Blast technique from the G'ak'arkan Tribe.
Together, these had given him a good understanding of how to manipulate the skies with one's breath. As long as he dedicated enough time to trial and error and continued to make enough progress down this path, he was confident that he would develop a sound and viable breathing technique mechanism that suited his needs.
As long as he wasn't too unlucky anyway.
He secluded himself in the forests of the Mantian Region as he dedicated himself to refining his breathing to learn to create the vacuum that he was looking forward to.
He tried varying his inhalation between different speeds, forces, angles, and patterns, making observations regarding the outcomes of each experiment.
('Inhaling through the nose seems universally less effective than that of the mouth when it comes to creating vacuums or areas of less air density,') Rui noted as he ruled out the former. ('Which means that I'll have to create the vacuum with my mouth.')
He had run into several issues when doing that. He wasn't inhaling air swiftly enough while in motion to be able to create a sustained vacuum before him. Furthermore, he wasn't able to isolate it to just the area right in front of his body making contact with him, instead, he inadvertently created areas of less air density momentarily that were spread over a wider area.
These were the two issues that he needed to focus on, otherwise, he had no hope of formulating the technique that he was looking for.
While he inhaled with his mouth for being able to create the vacuum the way he desired better, he exhaled through his nose, pushing the air down rather than forward. If he exhaled with his mouth, then he would generate a recoil pushing him back and obstructing his sprint.
Pushing it downward would have no effect on his horizontal speed.
He grew so absorbed in the training that he had secluded himself a for a week, relying only on food pills and Hungry Pain's autophagy to sustain himself the entire time.
In just a week, he had made commendable progress.
('This technique will take less time than the remaining two projects,') Rui had already realized that. Not only had he completed the theoretical structure of the technique fully, but he had also taken a step or two, albeit the easiest, towards completing the technique. In fact, he was quite certain that Project Keep Up With Kane would take the least amount of time to be completed in all the projects he had attempted.
The other two projects were more complicated, and most likely would require much more extensive research since they required knowledge outside of his knowledge base and would most likely require more extensive research and experimentation.
