The Martial Unity

Rui decided to call it a day for the training of the Tempestuous Feel. While had made remarkable progress in a single day, he had quickly discovered the hard limit that no number of tricks would help him overcome, from here on out it would be grueling sustained hard work over a long period of time. Once Rui was done with the technique, he got out of the sweaty suit, feeling the satisfaction of all his senses returning, including the Primordial Instinct technique.

"Incredible work sir!" The assistant came to his aid. "I look forward to your next training session!"

"Hm?" Rui threw an odd look at him. "Ah, er, yes, thanks."

He ignored the strange assistant before heading towards the long-range offense training facility. It was one of the largest facilities in the entirety of the Martial Union branch, for obvious reasons. In fact, Rui was partly worried whether it would be able to facilitate his needs considering the kind of technique that he sought to develop.

Once he entered the facility, he took the time to sit in the corner as he unraveled the scroll for the Sonic Bullet technique, before reading through it as quickly as he could, inputting all the data into his mind palace before closing the scroll and keeping it away.

It took him a while to process all the data he had come across.

('Interesting.')

The technique first required conditioning of the larynx by applying stress to it, causing it to grow thicker over time. This was the very first step taken that was necessary to generate powerful sound waves that could be concentrated into a bullet.

After that, Rui would be subjected to a vocalizing strengthening stage where his ability to generate sound would be exercised with breathing apparatuses that were mechanically designed such that one could not exhale through it unless one generated a certain degree of sound. The difficulty of the apparatus would be continuously increased over time as Rui improved, strengthening his larynx and his diaphragm.

The final stage of the technique involved learning how to efficiently convert the power potential energy in one's diaphragm when fully inhaled into sound energy and learning how to direct that sound energy.

It was definitely going to be different from the techniques he had learned prior.

"Ah, the Sonic Bullet technique, is it?" An assistant helper nodded. "I will fetch the conditioning device for the first phase."

"Please do." Rui nodded.

Rui put on the device, resembling an oxygen mask, on his face as the assistant aided him with the functioning of the device.

"RRGH!" Rui gritted his teeth once the conditioning process began. A tremendous amount of pressure was exerted onto his larynx. He felt as though he was choking. He couldn't even scream due to the fact that his larynx couldn't even contort under the pressure causing him to lose his voice while he was under training.

He wasn't even sure with what mechanism with which the device was exerting pressure on his larynx, but he didn't particularly care at the moment. He quickly gathered his composure as he breathed through his nose.

The exposure of his larynx to pressure on its tissue over time would cause it to become stronger, allowing it to be able to project the intensity of the sound he needed for the sake of the technique. Tissue tended to develop a greater degree of toughness due to long-term exposure to pressure. This was one of the ways that the human body could adapt to its external circumstances.

A few hours passed before Rui could finally take off the wretched device, drinking a healing potion as soon as he could. The moment he was done, he left the facility without a moment's waste.

He did not enjoy the training for the Sonic Bullet technique one bit, especially when compared to the highly pleasant training that he had experienced with his previous technique's training. Hell, it was almost as though they balanced each other out. One was quite fun, while the other was straight torture.

"That was rough." Rui sighed as he skywalked back home.

He had already completed all of his remaining business in the martial Union, all he left to do was go home and go through the results of the poison compatibility tests.

('And also begin developing the core techniques for the Bounce Project.') He sighed.

Out of all three projects, Project Bounce was the one technique that he had yet to make any progress with. He needed to immediately start developing techniques for the core principles of Project Bounce, until he did that, he would not be able to take a single step towards successfully realizing the project.

('But how am I going to do that?') Rui wondered.

He needed to figure out a way to actually at least get his foot in the door. The progress of one project could not lag too far behind the others, otherwise, he would be more inclined to abandon it. However, the ambition of Project Bounce was certainly something that was still alluring to him to, he would rather it succeed in any way he could.

('Even the simpler of the two problems, elastically observing all her kinetic energy and converting it to my body's own kinetic energy is quite hard.') Rui sighed. ('I would literally need to be made out of rubber or springs for such a thing to be poss-!')

His thoughts paused as an idea flashed through his mind.

('Made out of springs, huh?') Rui considered that thought.

It was, of course, impossible for him to be made out of springs, but that didn't mean he couldn't get the next best thing.

('Springs are coiled wires that exert a restoring force on themselves, when stretched or pressed, that is directly proportional to the degree of their stretching or pressing.') Rui recalled the basics about springs.

('If I can replicate the functionality of a spring with my own body by mimicking their mechanics with my body.') Rui glanced down at his hands. ('I might just have a fair chance.')
