The Martial Unity

An eternity of agony passed on. Rui had no idea how much time had passed since the commencement of the evolution procedure. His internal clock had completely been shot thanks to all the pain, and even metabolic phenomena were no longer reliable because of how much his body was rapidly changing. Due to that, things like hunger and thirst were no longer reliable indicators of how much time had passed since he had consumed any food.

The procedure didn't have a defined time limit. This was because everybody had different physiologies and metabolisms that caused the procedure to require different amounts of time to complete successfully.

The psychological effect this had on him along with the pain was not light. It placed an immense burden on his psyche. It wasn't easy maintaining absolute mental fortitude in the face of an unknown amount of agony. This was despite his superhuman mental fortitude by virtue of his mind growing twice and him being a Martial Apprentice. He felt as though if he was an ordinary person he would have lost his mind by now, or at the very least be afflicted with severe PTSD

He gritted his teeth as the pain shifted to different parts of his body within him over long periods of time. He could even vaguely sense which parts of his body were undergoing the evolution process. After the evolution process was done with his bones, they moved on toward his abdomen.

('My digestive system?') He wondered, through the pain.

He knew that the process acted system by system. If the pain was inside his abdomen, then there were a limited number of options it could be. By narrowing down all the possibilities, by eliminating possible systems that didn't match up with the place he was experiencing pain in, he could more or less figure out which parts of his body were undergoing the evolution process at any given time.

He gasped as his throat felt like it was burning. He felt like he had gotten the worst sinus infection that could possibly afflict a human body. Every second, he was in absolute agony, struggling to breathe as he felt like he drunk a glass full of concentrated acid.

Thankfully, his lungs and trachea were perfectly functional, otherwise, he would be completely unable to breathe at all.

Time passed on and on, as he gritted his teeth, keeping track of the pain as it shifted after long periods of evolution.
