A sudden, sickening lurch. Not a physical blow, but the sensation of being torn from existence and then forcibly reassembled, a brutal stitchwork of flesh and memory. This was the new normal, the prelude to yet another iteration of the siege. Kim Hyu-Gi opened his eyes, already knowing the metallic tang of fear in the air, the guttural roar of the demon horde, and the distant, mournful cries of the city’s populace. He stood on the crumbling battlements of Eldoria, the lowest rung of the knightly order, his standard-issue longsword feeling like a leaden stick in his grip. The thin, dented armor offered little more than psychological comfort against the tide of horrors he knew awaited. He had died eighteen times already in this particular sequence of the simulation, each death a unique lesson in futility. Crushed beneath the hooves of a charging Ghoulbeast, incinerated by the emerald fire of a Vile Sorcerer, impaled by the barbed tail of a Skitterer demon. The pain was always absolute, the fear of oblivion utterly convincing, even though he knew he would always return. But the terror was slowly, meticulously, being replaced by a cold, calculating detachment. He no longer screamed; he observed. He no longer panicked; he analyzed. His mind, once a tempest of desperate survival instincts, was now a ledger, meticulously recording variables. “Another wave incoming!” a grizzled sergeant bellowed, his voice raw. “Hold the line, you curs! For Eldoria! For the Princess!” Kim Hyu-Gi didn’t respond, his gaze fixed on the churning mass below. The sheer numbers were overwhelming, a black sea of teeth and claws. He had learned that the initial assault was a feint, designed to draw out the city’s strongest defenders. The real threat always came from the flanks, spearheaded by the Bloodfiends—hulking, crimson-skinned brutes that moved with surprising speed, capable of tearing through a knight’s shield and armor as if it were parchment. His last three deaths had come at the hands of Bloodfiends, specifically when they burst through a narrow breach near the southern gate. The first time, he’d been too slow to react. The second, he’d been caught trying to cover a wounded comrade. The third, he’d misjudged their reach, a mistake that cost him his head. This time, he decided, would be different. He wouldn’t be a reactive pawn. He would anticipate. As the main demon force slammed against the city walls, the air thick with the stench of brimstone and iron, Kim Hyu-Gi subtly shifted his position. He moved away from the thickest concentration of knights, drawing a questioning glance from a broad-shouldered knight named Sir Kael, whose chest bore a dozen scars from previous skirmishes. Kael often eyed Hyu-Gi with a mixture of pity and contempt, viewing him as just another weak link. Hyu-Gi ignored him, his focus absolute. “You running, whelp?” Kael snarled, his voice barely audible over the din. “Observing,” Kim Hyu-Gi muttered, a response Kael scoffed at, turning his attention back to the grotesque figures scaling the walls. Hyu-Gi had identified a peculiar pattern. The Bloodfiends, while powerful, were not intelligent. They followed the path of least resistance, and the southern gate, always a weak point, became even more so after the initial, disorganized demon push created an opening. Furthermore, he’d noticed that a specific Vile Sorcerer, identifiable by a single, glowing red eye, always hovered near that sector, casting debilitating curses just before the Bloodfiends made their move. He had only F-class stats in the real world, but here, the system had adjusted him to the lowest knightly rank, giving him just enough to swing a sword without collapsing. Yet, his mind, sharpened by the endless battlefield of the first simulation, was his true weapon. Minutes bled into an eternity of clangor and screams. Knights fell, replaced by others. The air grew heavy with the tang of spilled blood and ozone. Then, just as he predicted, a section of the southern gate began to buckle under a renewed, focused assault. Simultaneously, the single red-eyed Vile Sorcerer soared into view, its vile incantations already beginning to hum in the air. “South gate! Breach incoming!” a panicked shout echoed. “Bloodfiends!” Sir Kael and a handful of stronger knights immediately charged towards the collapsing section, their heavy armor clanking. They would engage the Bloodfiends head-on, sacrificing themselves to buy time. It was a valiant, but ultimately suicidal, tactic in the face of such overwhelming numbers. Kim Hyu-Gi didn’t follow. Instead, he darted in the opposite direction, toward a cluster of archers positioned higher up on a less-defended tower. He knew they wouldn’t stop the Bloodfiends, but they were in the perfect position to target the Vile Sorcerer. He’d died enough times to understand that neutralizing the support was sometimes more critical than engaging the primary threat. “Aim for the sorcerer!” Kim Hyu-Gi yelled, his voice surprisingly clear, cutting through the chaos. He pointed with his sword. “The one with the glowing eye! It’s weakening the gate!” The archers, initially startled by the low-ranking knight’s sudden outburst, hesitated. They were trained to follow orders, not take them from a grunt. “It’s a distraction!” one of them yelled, nocking an arrow aimed at a climbing Imp. “The gate is falling!” “The gate falls *because* of it!” Kim Hyu-Gi insisted, pushing past them, snatching a discarded bow. His aim was terrible, his arm unaccustomed to the draw weight, but he loosed an arrow regardless, a desperate gesture. It sailed wide, harmlessly striking the wall below. Yet, his insistence, his sheer, uncharacteristic confidence, caught the attention of an older archer, whose eyes had seen too many battles. The sorcerer was indeed focusing its energy, a malevolent aura pulsing around it. “He’s right!” the older archer barked, adjusting his aim. “Focus fire on that demon!” Three arrows, then five, then ten, arced through the smoky sky, whistling towards the Vile Sorcerer. One struck its wing, another embedded itself in its shoulder. The demon shrieked, its glowing red eye flaring with pain and rage, and its concentration shattered. The debilitating curses it was preparing to unleash on the gate defenders dissipated. Just then, the southern gate gave way with a sickening splintering sound. Three colossal Bloodfiends, their hides slick with gore, burst through the opening, roaring. They immediately engaged Sir Kael and his brave, but outmatched, knights. Kim Hyu-Gi watched, knowing he had bought mere seconds, perhaps a minute, for the defenders. Without the sorcerer’s curses, their resistance would be marginally stronger. He had not saved the gate, nor had he saved the Princess’s chances of escape. He had simply changed the timing of their inevitable demise. His triumph was fleeting. A Ghoulbeast, drawn by the commotion on the tower, suddenly lunged from a shadowed corner, its foul breath washing over him. He saw the gleam of its claws, registered the sickening crunch as they tore through his arm, then his chest. Darkness. Pain. The familiar rip of his essence. He was dead again. But as the simulation reset, bringing him back to the familiar, chaotic precipice, a new data point burned in his mind: focus fire on support units. It was a small victory, a tiny fracture in the overwhelming wall of despair. The Princess was still trapped, the demons still countless, but Kim Hyu-Gi had taken another step, one calculated death at a time, closer to understanding the true calculus of survival in this hellish world.
