Final Growth...

Hayatou practically dragged himself inside his home, his body aching all over, covered in countless bruises from head to toe. Every step felt like he was walking with lead weights strapped to his limbs, but despite the exhaustion, a small smirk tugged at his lips.

[That was a very good session, host. Your combat sense has already improved by 35.33%. I look forward to seeing more of your growth.]

"Yeah, thanks. But knowing I'm going to feel pain doesn't exactly make the process any easier…" he whispered, wincing slightly as he stretched out his shoulders. His entire body throbbed from the sheer punishment he had put himself through. The simulation had been brutal—far beyond anything the Academy could offer. But that was exactly why he needed it.

He let out a deep breath, still processing everything he had just experienced. He had set the simulation to the highest difficulty, and it had damn near broken him. This level of the simulation simulated pain to an extremely realistic degree, if his head got sliced off, he would feel 99.8% percent of the pain...

But it was worth it.

[Yes. Pain is a good teacher, and suffering creates stronger men.]

'Yeah, easy for you to say...'

Hayatou carefully walked through the kitchen, seeing multiple bowls of food resting on the table. His hunger kept growing and growing ever since he had started his journey; and lately, it's been dawning on him about the amount of money his mother must be spending to keep up with his ever growing appetite.

....

"Tch..."

He shook his head, clearly annoyed by the current situation; what's worse, she's never stopped him, never questions him and never berates him for coming home this late and tired; She was a good woman...

'N.E.O, there might be a slight altering in our plans from here on out...'

[...What do you have in mind host?]

'I'm saying; I'll need to show my strength after all.'

[I will aid you in the best way I can...]

He smiled, 'Good... For now, we do what needs to be done; Follow through with the last body reconstruction and we can head on forth from there. I'll need to be the best, and be the best quickly.'

He hoped it wouldn't come to this, but he was sure his mother was tired from having to work over time to aid him. He was sure it's why he hasn't even seen her as of late. Yet, she always makes sure his meals are there...

Hayatou sat on the chair, eating his meal quickly before going to start.

[Alright, seeing that my full capabilities are now unlocked. I can alter your genetic structure and physique to it's most optimized capabilities... Are you ready?]

'Yes...'

[Affirmative... Administering anesthetic, in 3... 2... 1...]

A sudden wave of numbness spread through his body. His limbs felt heavy, his vision blurred, and within moments—

Everything went black.

Hayatou opened his eyes, already feeling the difference in his entire body...

'Hmm...' He slowly sat up, feeling the familiar viscous fluid on his body.

'Yuck!~'

[It seems you are finally awake host, do you want me to review the changes in your body?]

Hayatou flexed his fingers, rolling his shoulders experimentally. Even that small motion felt smoother, more natural, as if every joint, every muscle fiber was working at peak efficiency.

"Yeah… Go ahead. Lay it on me."

[Understood, host... Your body has undergone a complete structural optimization. Unlike previous reconstructions, which focused on strengthening and accelerating adaptation, this process was designed to repurpose your biological systems toward maximum possible efficiency in chakra flow, combat adaptability, and overall bodily function.

First, your nervous system has been fully optimized. Neural pathways have been refined to match your physique with 100% accuracy, reducing unnecessary signal transmission lag. Your reaction speed is now limited only by your chakra-enhanced muscular response, eliminating delays caused by inefficient bioelectrical conductivity. Additionally, redundant pain receptors have been dampened to prevent excessive response to non-lethal damage, ensuring combat focus is not impaired.

Next, your circulatory system has been reconstructed for chakra efficiency. Blood vessels have been repurposed into an intricate chakra distribution network, minimizing energy loss during molding and release. Microcapillary networks have been reinforced, allowing rapid oxygenation and chakra saturation to key muscle groups, improving stamina and prolonged high-output activity. Your muscles and ligaments have been reconstructed with kinetic optimization in mind. Rather than brute-force strength enhancement, muscle fibers have been realigned for maximum elastic recoil efficiency, allowing greater force output with minimal energy consumption.

Ligaments have been reinforced with microscopic chakra retention structures, reducing strain and improving tensile durability, meaning your joints can withstand rapid bursts of movement without degrading. Your skeletal structure has been reworked to improve combat durability. Structural density has also been redistributed, prioritizing weight-to-strength ratio. Load-bearing bones—such as your femurs, spine, and humerus—have been reinforced without increasing mass, allowing for sustained combat impact without energy inefficiency by 25.4%. Additionally, the marrow has been modified for increased chakra-infused blood cell production, allowing for higher regeneration efficiency and faster recovery from fatigue...

To clarify: this process has not made you stronger in the conventional sense, nor has it boosted your growth rate beyond the existing 20% improvement from intensive training. Instead, it has ensured that your current strength, agility, and endurance are functioning at their absolute peak, removing all biological inefficiencies, enhancing you previous biological limit. This allows you to utilize 100% of your body's potential at all times. Additionally, your chakra molding potency has been further improved greatly by 223.2%, and efficiency by 45.22%; reducing energy waste and maximizing overall output. Furthermore, you chakra pathways are 37.2% larger than before... In essence, host, you are now operating at the absolute pinnacle of human efficiency—a fully optimized system built for combat, chakra control, and sustained growth.]

Hayatou sat there, absorbing everything N.E.O. had just told him. He flexed his fingers again, feeling the near uncanny smoothness in his movements. It truly felt like every part of his body, down to even the smallest detail, had truly been rebuilt for pure efficiency.

And that scared him a little...

According to N.E.O, he wasn't even stronger either.

'That's quite the pill to swallow.... Show me my attributes.'

[Affirmative, also. I have added a new section for your natural capabilities; they have now reached a level where they can be perceived as a super-power...]

'Yeah, those were pretty large increases...' 

He got up quickly, taking up his dirtied clothing and futon from the process. Wanting to wash off. But as he stood, he felt that his view had shifted again.

'I'll just have to get used to my height increase again...' He thought tiredly, walking towards his bathroom...
