Fuji sat cross-legged on the dusty floor of the shrine's main chamber, the faint scent of damp wood and forgotten incense permeating the air. His eyes were closed, his breathing slow and deliberate, a practiced rhythm from a life he barely remembered. He focused inward, seeking… something. Anything. His "Status Panel" remained blank, a silent, mocking testament to his current powerlessness. He knew, intellectually, what chakra was. A fusion of physical and spiritual energy. A life force. But knowing was one thing; feeling it was another entirely. He strained, willing an internal warmth, a tingle, a spark. Nothing. Just the hollow echo of his own heartbeat and the distant rustle of leaves outside. The sheer, overwhelming *nullity* of it was disheartening. "This is harder than it looks," he muttered, opening his eyes to stare at the flaking paint of a faded mural depicting what might have been a fox or a dragon. His memories, fragmented and hazy as they were, contained vivid images of children in academies performing simple chakra exercises with ease. Tree walking, water walking – fundamental skills that relied on precise chakra control. He, a supposedly transmigrated soul with a vast (if theoretical) knowledge of this world's mechanics, couldn't even sense the primordial energy flowing within his own body. It was like trying to pilot a complex machine without knowing where the power button was. He spent the better part of the morning in this futile pursuit, alternating between intense concentration and frustrated sighs. His analytical mind, accustomed to problem-solving, cataloged his failures. Perhaps his spiritual energy was underdeveloped? Or his physical energy too weak? Could his unique transmigration somehow inhibit the natural awakening of chakra? The questions piled up, each one adding another layer to the daunting task ahead. Immortality, in this world, was achieved through mastery of chakra and jutsu, often through morally compromising means. His goal was to find a *different* path, one that didn't involve stealing bodies or sacrificing others. But even that path began with this elusive internal energy. By midday, his stomach rumbled, a stark reminder of his very mortal needs. He couldn't sustain himself on meditation and frustration. He needed food, water, and most importantly, information. The shrine, while a temporary sanctuary, offered little beyond shelter. He had to venture out. --- The forest canopy filtered the sunlight into dappled patterns on the forest floor, casting long, shifting shadows. Fuji moved with a slow, deliberate caution, his senses hyper-alert. Every snapping twig, every chirping bird, every rustle of leaves was scrutinized. He kept to the densest undergrowth, his dark, unremarkable clothing helping him blend into the shadows. He knew, from his fragmented knowledge, that this world was teeming with dangers far beyond mere wild animals. Bandits, rogue ninja, rival villages – the list was endless. He was a civilian in a world of trained killers, and his "cheat" only offered theoretical knowledge, not immediate power. He walked for what felt like hours, circling the shrine in an expanding perimeter. He found no clear paths, no obvious signs of recent human habitation, which was both a relief and a source of anxiety. Relief because it meant fewer immediate threats, anxiety because it meant he was truly isolated, far from any potential resources or information. The trees here were ancient, their roots gnarled and thick like sleeping pythons. Moss clung to their trunks, and the air was thick with the scent of pine and damp earth. Eventually, his meticulous search yielded a faint trace: a narrow game trail, barely visible, but distinct enough from random animal paths. It was too regular, too worn in certain places, to be purely natural. Human activity. He followed it, his pace slowing even further, every step placed with excruciating care. He peered through the foliage, scanning for traps, for tripwires, for anything that might indicate a hostile presence. The tension in his shoulders was a constant, dull ache. The trail led him deeper, past a small, gurgling stream where he gratefully drank his fill, the water cold and clean. He refilled the empty bottle he'd found in the shrine. He continued, his hunger a distant throb compared to the sharp edge of his fear. Then, he heard it. Voices. Muffled at first, then clearer. Young voices. He immediately froze, dropping into a crouch behind a thick bush, his heart thudding against his ribs. He strained his ears. "...told you, Kaito, the Elder said we *have* to find all five of them by sundown," a high-pitched, slightly exasperated voice chirped. "Relax, Akari. We've got three already. And besides," a deeper, more confident voice replied, "you’re faster at spotting the Azure Sprout anyway. Just don't let those thorns prick you again." "They're called 'protective barbs'!" a third, more gruff voice interjected. "And they're annoying. Just use a kunai to snip them, Akari." Fuji carefully parted the leaves, peering through a narrow gap. About twenty meters away, in a small clearing bathed in sunlight, stood three figures. Genin. Two boys and a girl, all dressed in standard Konoha-style ninja attire, complete with headbands. They looked to be no older than twelve or thirteen. They were meticulously examining a patch of peculiar, iridescent blue plants, carefully plucking them and placing them into a canvas sack. His mind instantly began to analyze. Konoha Genin. D-rank mission, likely. Collecting medicinal herbs, given their conversation. He observed their movements: fluid, almost instinctive. Even in this seemingly mundane task, their posture was alert, their eyes constantly scanning their surroundings. One of the boys, Kaito, effortlessly vaulted over a fallen log that Fuji would have had to carefully climb over. The girl, Akari, plucked a sprout with a precise, almost surgical movement of her fingers, avoiding the "protective barbs." The third boy, whose name he hadn't caught, swiftly drew a kunai to clear some dense foliage, the blade flashing in the sunlight before being sheathed with practiced ease. He felt a cold dread settle in his gut. These were *children*. Yet, they moved with a grace and efficiency that spoke of years of rigorous training. Their tools – kunai, shuriken (he spotted a faint outline of a pouch on Kaito's leg), their uniforms, their coordinated movements – all screamed "trained killer." He was just a man from another world, with knowledge but no physical prowess. He was utterly vulnerable. The sight of these young ninja, casually going about a simple task, solidified his understanding of the world's dangers far more effectively than any abstract memory could. This wasn't a world where intellect alone guaranteed survival. This was a world where even a simple herb-gathering mission involved individuals capable of ending his life in a blink. As the genin moved further into the clearing, their voices fading, Fuji slowly extracted himself from his hiding spot. His earlier frustration with chakra control seemed almost trivial now. His immediate goal wasn't just to *sense* chakra; it was to survive long enough to even *begin* the path to immortality. This dilapidated shrine, as temporary as it was, wouldn't suffice. He needed more. He needed resources, a secure, hidden laboratory, and a level of secrecy that bordered on absolute invisibility. The true scale of his undertaking, and the immense power required to even *start* it, truly began to sink in.
