Chapter 6: The Forge of Will
Absolutely not. Eating soft rice was not an option. It would never be an option!
Shinra stored the medical supplies with a grimace. He probably wouldn't need them in this lifetime, but the gesture was noted. The sting of that well-intentioned pity, however, burned hotter than any training injury.
Fuelled by a fresh, simmering indignation, he didn't even consider sleep. He dropped to the floor of his small room and began to exercise. The rhythm was furious, punishing.
Unbelievable! A joke!
The thought pounded in time with his heart. If I don't get stronger, I'll be the guy Kushina has to protect! Her personal charity case!
The very idea was galling. Sure, being taken care of by a pretty girl had its superficial appeals… but he was supposed to be a man! A warrior! This was unacceptable!
Lost in this churning motivation, he'd already blasted through nearly a thousand push-ups. Sweat poured from him, pooling on the wooden floorboards in a growing, person-shaped puddle. The clean feeling from his bath was long gone, replaced by the raw burn of exertion.
His arms turned to lead, trembling violently. His joints screamed in protest, threatening to buckle under his own weight. But in his mind's eye, he saw it clearly: a pathetic version of himself, cowering behind Kushina's vibrant red hair, reliant on her strength.
His arms went numb, sensation fading into a dull, distant roar of pain. Yet, through sheer willpower, he forced them to move again, dredging up reserves of strength from muscles that had already given up. He pushed until his arms completely gave out, collapsing face-first onto the damp floor, his chest heaving as he dragged in ragged, desperate breaths.
But after only a minute of gasping, the fire in his eyes hadn't dimmed. It had intensified. He shoved himself up, his arms hanging uselessly at his sides, and began a brutal set of squats.
This was the core of the foundational regimen from Whitebeard's legacy. When one part of the body failed, you trained another. Arms gone? Use the legs. Legs jelly? Work the core. There was no true rest, only a relentless, rotating assault on the body's limits. It was a method of forging oneself through constant, efficient, and inhuman pressure.
Of course, such training was suicidal without corresponding fuel. Breaking the body down required immense resources to build it back stronger. The legendary appetites of the world's powerhouses weren't a quirk; they were a physiological necessity. To train like a monster, you had to eat like one. The method also included techniques for maximizing nutrient absorption—a crucial, often overlooked secret that separated the strong from the broken.
This extreme forging method might be standard for the elites of the Grand Line, but in the shinobi world, it was borderline revolutionary. Here, chakra reserves were largely dictated by innate talent and bloodline. Hard work could only take you so far before you hit a genetic wall. Some, like Jiraiya, sought external energy sources, but those came with their own limits and conditions. Others, like Might Guy, used secret techniques to burn their life force for a fleeting, glorious peak.
Shinra's path was different. The Extreme Forging Method offered a way to systematically break that wall. Not just once, but repeatedly. It wasn't about a temporary boost; it was about permanently raising his ceiling. His physical limit—and by direct extension, his chakra capacity—wasn't fixed. It was a frontier he could keep pushing back.
He wasn't just training his body. He was actively overwriting his own supposed lack of talent.
The implications were staggering. Given enough time and relentless effort, there was no reason his physicality and chakra couldn't rival, or even surpass, that of a Sage Body. The human body was a treasure trove of untapped potential. The only real limit was one's willingness to endure the pain required to unlock it.
Thinking of this, a wild, exhilarating energy surged through Shinra, cutting through the fatigue. His body, which moments ago had felt like a sack of broken pottery, twitched with renewed purpose.
With a guttural growl, he forced himself to move again, finding a new angle, a new muscle group to torture. The night was young, and his determination was infinite.
