The familiar sensation of a violent tear, then a sudden lurch back to conscious thought, was no longer jarring. It was merely the system’s brutal handshake, pulling Kim Hyu-Gi from one death to the next, a relentless cycle of oblivion and rebirth within the besieged medieval city. He stood again at the outer wall, the acrid stench of burning pitch and unwashed bodies a constant companion, the distant, guttural roar of the demon horde a perverse lullaby. His muscles, though reset, thrummed with phantom aches from the last few dozen iterations. Each 'reset' was a clean slate for his body, but his mind carried the accumulated trauma, a grim ledger of every failure.\n\nThe city, a crumbling bastion against a tide of infernal horror, was always the same. Stone walls scarred by countless assaults, banners tattered by demonic claws, and the same five thousand knights, their faces etched with despair and resignation. He was still the weakest among them, barely more than cannon fodder, equipped with a dented steel helmet that offered dubious protection, a cheap leather cuirass, and a standard-issue longsword. Its edge, he’d noticed after hundreds of resets, was often chipped even before the first clash.\n\n“Hold the line!” a grizzled knight, Sir Kael, barked from a nearby battlement. Kael was a constant, a paragon of futile courage, always falling in the same breach, usually to a towering Gargoyle or a particularly nasty Brute Demon. Kim Hyu-Gi had seen Kael’s death more times than he’d seen his own face in a mirror.\n\nHis current assignment was familiar: a futile defense of a secondary gate, destined to fall within the first hour of the major assault. In his earliest attempts, he’d fought with panicked desperation, swinging his sword wildly, reacting to every threat. He’d lasted minutes, sometimes seconds. The raw terror of being torn apart by a Hell Hound, impaled by a hulking Brute, or dissolved by an Imp’s corrosive bile had been overwhelming. But now, after what felt like an eternity of dying, panic had curdled into a cold, calculating resolve.\n\nThe demons surged forward, a churning sea of black and red. Imps, scuttling like oversized insects, were the vanguard, their high-pitched screeches piercing the din of battle. Behind them lumbered the larger Brutes, their heavy clubs capable of shattering stone, and the more agile Hell Hounds, their fangs dripping with venom. Each type, he knew, had its own rhythm, its own tell.\n\nHe watched the first wave with detached intensity. An Imp, notorious for its erratic movements, darted towards a younger knight to his left. The knight, inexperienced, lunged forward with a wide, telegraphed swing. Too slow. The Imp, anticipating, dodged effortlessly and clawed the knight’s face, spraying blood. Kim Hyu-Gi mentally logged the failure: *over-commitment against Imp. Maintain guard, wait for opening.*\n\nHis own strategy had evolved. No more reckless charges. No more desperate parries against impossible odds. He had begun to approach each life as a laboratory, each death a data point. The objective, to escort the Princess, seemed laughably distant. His immediate objective was simpler, more fundamental: *learn, survive longer, identify patterns.*\n\nHe focused on an Imp that veered towards him. Its movements were still quick, but not entirely random. There was a micro-pause, a fractional hesitation before its lunge, almost imperceptible. In his first hundred attempts, he’d never noticed it. In his last ten, he’d started to register it. This time, he didn't react with a full block. Instead, as the Imp paused, he shifted his weight, allowing the small creature to commit, then twisted his wrist, guiding his chipped longsword’s hilt to deflect the Imp’s claw, not directly, but with a glancing blow that threw the Imp slightly off balance.\n\nIt wasn’t a kill, but it was a minor victory. The Imp stumbled, giving him a precious half-second to follow up. He didn’t strike for a vital point—those were too well guarded. He aimed for a joint, a knee-cap, a less armored section. His blade scraped against chitinous leg armor, sending sparks flying but doing no real damage. Yet, he hadn't died. Not yet. The Imp recovered, its beady red eyes narrowing.\n\nA Brute Demon, a hulking monstrosity of muscle and bone, smashed into the wall section to his right, sending shrapnel flying. Two knights were instantly pulped. The roar of the Brute was deafening, a visceral reminder of the sheer power he was up against. He'd died to Brutes countless times, crushed, broken, splattered. But he’d also learned their tells: the slow, winding up of their clubs, the brief shift of weight before a charge.\n\nHe was still in a defensive stance, eyes darting between the Imp in front of him and the chaos around. Another Imp flanked him, a move he’d anticipated based on previous simulations. He executed a short, sharp pivot, bringing his shield (a small, dented buckler that felt more like a toy) up just in time to block the second Imp’s ambush. The impact jarred his arm, but he held his ground.\n\nThis was progress. Measurable, though agonizingly slow, progress. In previous runs, two Imps would have overwhelmed him in moments. Now, he was managing to hold them off, even if he couldn't inflict damage. The key was observation, not brute force. He needed to understand the 'rules' of this particular iteration of hell.\n\nHe found himself thinking less about the horrors of the battlefield and more about the mechanics of the demons. The way a Hell Hound always favored its left paw for its initial swipe, how the smaller Succubi, when they occasionally appeared, would always try to circle to a knight’s blind spot before striking. He was compiling an internal encyclopedia of death, each entry a lesson hard-earned.\n\nSuddenly, a massive shadow fell over him. The Brute Demon from earlier, having breached the wall, now stomped towards his position. Its eyes, twin coals of malevolent fire, locked onto him. Fear still tried to claw its way into his throat, but he choked it down. *This is a known pattern,* he told himself. *The Brutes always exploit the initial breach. They focus on the nearest cluster of knights.*\n\nHe didn’t try to fight it head-on. That was suicide. He had tried that, hundreds of times, and died every single time. Instead, as the Brute raised its colossal club for an overhead smash, he didn’t move back. He moved *forward*, a sudden, unexpected dart beneath its guard. It was a risky maneuver, one he'd only recently dared to attempt. The wind of the descending club ruffled his hair as he slid past, a hair’s breadth from being splattered.\n\nHe was now behind the Brute, a momentary reprieve. Other knights, seeing the lumbering demon, bravely or foolishly engaged it from the front. This was his chance. He aimed for the back of its knee, a joint he’d noticed was slightly less armored than the rest of its thick hide. He brought his longsword down in a sharp, almost surgical strike. *Clang!* The blade bit deeper this time, not a scratch, but a shallow gouge.\n\nThe Brute roared, a sound of pain and rage, not just annoyance. It twisted, disrupting the knights attacking its front. Kim Hyu-Gi used the moment of confusion to retreat, creating distance. He hadn't killed it, but he had wounded it. A tiny, insignificant wound in the grand scheme, but for him, it was a monumental breakthrough. He had survived an encounter with a Brute Demon, and even damaged it, something he hadn’t managed without dying immediately until very recently.\n\nHe felt a surge of cold satisfaction, quickly followed by the familiar chill of dread. The wound he’d inflicted wouldn’t change the outcome of this particular run. The Brute would still tear through the knights, the city would still fall, the Princess would still be lost, and he would still die. But the *data*. The data was accumulating. Each precise block, each calculated dodge, each deliberate strike was a fragment of a larger puzzle.\n\nHe spotted a small group of three Goblins, smaller, weaker variants of the Imps, but still dangerous in numbers, scurrying towards a fallen knight. The knight was still alive, groaning, but pinned. Kim Hyu-Gi saw an opportunity. Not to save the knight—that was often impossible—but to test a new combat sequence he'd been mentally rehearsing.\n\nHe charged, not with a roar, but with a silent, focused intensity. He met the first Goblin with a diagonal cut that caught it across the chest, surprisingly effective. The creature shrieked and fell. The second Goblin lunged, and he parried its rusty dagger with his buckler, then immediately followed with a thrust. The blade found its mark, piercing through thin leather armor. Two down. The third Goblin, momentarily stunned by the efficiency, hesitated. Kim Hyu-Gi didn't give it a chance. He closed the distance, a quick, brutal horizontal slash, and the last Goblin crumpled.\n\nHe stood over the three felled creatures, breathing heavily, his own body aching from the exertion, even if the phantom pain of past deaths was worse. This wasn't the first time he'd killed a Goblin or an Imp. But killing three, in quick succession, with a degree of controlled precision, without taking a single hit, was a new milestone. It showed that his understanding of their attack patterns and his own limited reach was growing.\n\nThe world around him was still a maelstrom of destruction. Knights screamed, demons roared, and the smell of blood and burning filled the air. He was a tiny cog in a vast, grinding machine of war, but he was learning how to make his cog turn more efficiently. The constant stream of death, the brutal resets, had forged a new kind of warrior from the F-Class hunter he once was. He wasn't stronger yet, not physically, but his mind, his instincts, they were sharpening into a dangerous edge. He was no longer just surviving; he was adapting. He was transforming the agony of endless failure into a weapon.\n\nA sudden, sharp pain in his chest, a sickening crunch of bone. He looked down. A Hell Hound, which he had failed to notice in his focus, had torn a gaping hole in his breastplate and ripped through his vitals. Its yellow eyes glowed with predatory satisfaction. He stumbled back, choking on his own blood, the familiar darkness rushing in.\n\nHe died again. And the world reset.\n\n---\n\nThe system prompt, cold and indifferent, flashed into his awareness as his consciousness stabilized:\n[SIMULATION RESET. RESTARTING IN 3… 2… 1…]\n\nHe opened his eyes to the familiar sight of the crumbling wall, the distant roars, the desperate cries. His hand instinctively went to the hilt of his sword. The pain was gone, but the memory, the data, remained. He was still the weakest knight, but he was no longer blind. Each death chipped away at his ignorance, revealing slivers of truth in this manufactured hell.\n\nThe next wave was already approaching. He gripped his sword, his gaze distant, already analyzing, already planning for this new, yet utterly familiar, iteration of his death.
