The Martial Unity

Rui stood in place as an extremely powerful wind current pushed at him. An ordinary human would have long succumbed to the wind pressure.

Rui turned to clear his doubts, yet his eyes widened as he saw the man sealing the entrance to the cave with a gigantically long boulder that was sealing the entrance shit

"Don't bother trying to break your way out, this place is close to the center of the mountain that is reinforced for huge distances in all directions with many strong rocks that will be extremely difficult even for you to break out before suffocating to death! This will last for about three hours since this is your first time. Please don't die."

Rui didn't even have time to complain about the lacking explanations and elaborations on the technique. He was accustomed to knowing the entirety of his training regime involved before he began it. Yet it turned out that this was not how things necessarily operated in the G'ak'arkan Tribe.

And he had no choice but to acquiesce, he would not allow Senior K'Mala to dictate how he would teach her, thus he could not expect the G'ak'arkan Tribe to do that for him.

THUD!

Somehow, the rock covered all the edges to ensure that there wasn't even a single avenue for air.

In less than a second, all of the air in the cave had disappeared, absorbed into the water. There was no replenishing air from the outside since the entrance to the cave had been shut.

Suddenly, Rui could not breathe anymore.

('I need to release sound in the water!') He recalled what Kt'obila said before jumping into the narrow hole of purple water.

THWOOM!

He immediately released a Sonic Bullet downwards.

A tremendous gush of bubbles pushed him back to the surface, where he found fresh cool air hitting his skin.

He gasped for air, but he only had a split second before the water absorbed all of the released air back into it.

He went back down again, mustering the air he just barely managed to inhale before launching another Sonic Bullet.

THWOOM!

Once more a huge wave of bubbles of air pushed him back to the surface where he once again gasped for air, before diving back down again and launching a Sonic Bullet.

THWOOM!

He barely managed to supply himself with the oxygen he needed t each time as he released sound time and time again to get what he needed.

Rui was just barely cognizant enough to realize that there was nobody around this cave, through Seismic Mapping.

('Meaning if I fail, then I'll suffocate to death and actually die here!') The thought flashed through his head as he gasped for more air.

This meant that he could not afford to mess up, his very life was on the line.

This drove his mind and body to their limit as he began going all-out while ensuring that he didn't miss a beat.

Very soon, his entire body began aching. The medium that he was in was water, which made things a lot different. The pressure and drag to movements that water produced were exponentially greater than the drag and pressure produced by the atmosphere. This applied regardless of how powerful one was. He had to exert much more effort than he would if he was doing those movements in the air.

The struggle of breathing reminded him of his asthma back on Earth. It was labored, hampered, and tiring. Each breath felt like he had to pull a huge load of rock with his inhalation

Furthermore, he had to admit that the fear of death did indeed put pressure on him.

His nerves were tingling, even Primordial Instinct warned him of the danger of the situation he was in. His body temperature rose he began sweating a lot. His heart rate was permanently high too.

This continued for about three hours.

Until the water turned normal as the purple solute of the solution subsided and delved to the bottom.

Finally, he could breathe properly.

He could even hear Kt'obila moving the large amount of rock and debris that he had closed the entrance of the cave with.

"Huff… Huff…" he panted as he enjoyed the ability to breathe normally. If nothing, this training at least taught him to appreciate things that he was starting to take for granted. Breathing normally was a gift.

Suddenly, the boulder shifted as he found Kt'obila at the entrance, who inspected his condition, before scratching his head. "I would have expected you to feel better given how strong you seem to be."

Rui didn't even bother responding. Even if he wanted to correct his misunderstanding, he did not want to talk, it would interfere with breathing after all.

"This technique puts a lot of pressure on the breathing force and your voice," He explained. "This will help strengthen it to the level that is required."

The man continued going into deeper detail as he explained more than he did initially.

"Once you've achieved the strength of breathing force and voice, we will move to learn how to shape the sound with your mouth before releasing it. Once you have mastered that, your training here with the Mighty Roar Flash Blast technique will be complete."

Rui nodded, wordlessly as he got on his feet. He was completely drenched, so he needed to squeeze the excess water out of his clothes before he could leave the place.

Rui was beginning to understand why the Martial Artists of Vilun Island were able to master techniques within reasonable periods of time despite severely lacking the technological training and growth resources of the Martial Union.

This has always been something he had pondered. How on Earth were the Martial Artists able to actually accomplish this? So far, there hadn't been any definitive answers even with the help of the intelligence team. The only thing that he had come to learn was the fact that their techniques were sacred and thus kept secret at all costs.

Yet, now he was starting to get an inkling of why they could master techniques at respectable paces despite not possessing the training resources of the Martial Union.
