Now the weakling rises.
Fueled by burning ambition and icy vengeance, Klein carves his path through blood and glory. He will claim endless wealth, shatter every throne, and make every soul who ever looked down on him scream his name in terror.

Chapter: The Shade
Boomer stood with his arms crossed, the arrogance on his face almost tangible. His voice boomed across the park, filled with pride. "I am one of the top 10 System Bearers in the world! Don’t get cocky, kid," he barked, his grin never faltering as if he expected Klein to back down just from hearing his rank.Klein didn’t even flinch. He eyed Boomer up and down, unimpressed. "Cocky?" he said, his tone sharp with disdain. He clicked his tongue, his arms crossing over his chest as he straightened up. "You’re the cocky one." His gaze didn’t waver, making it clear that titles and ranks didn’t intimidate him.Boomer’s grin twitched, clearly not used to being talked down to, but before he could respond, Klein shot forward, closing the gap between them. They clashed again, fists flying, each hit reverberating through the park like mini-explosions. Boomer swung his fist, a brutal haymaker aimed straight at Klein's head, but Klein dodged it effortlessly, his ARCHFIEND scales shimmering as he nar

Chapter: Taste of Fame
As Klein stood in the alley, watching Vax disappear into the shadows, a sudden realization washed over him. He wasn’t alone. Dozens of people crowded at the alley’s entrance, their faces lit up with awe. Phones hovered in the air, recording every moment of the duel he’d hoped to keep under wraps. His brow furrowed, and his wings twitched slightly as his eyes scanned the sea of glowing screens. The whispers had already begun to swell, rippling through the crowd."Is that... Klein S’roar?" one person murmured, their voice brimming with excitement."Did you see those flames? Golden and black... like something out of a myth!" another said, their phone raised high, capturing the last moments of the spectacle.Klein let out a low, frustrated sigh, running a hand through his hair as he dropped to the ground, sitting with a thud. His ARCHFIEND wings folded neatly against his back, but the tension in his posture made it clear he wasn’t pleased with the attention. "Well, so much for keeping thi

Chapter: A Duel Between Men
Klein's expression shifted, his usual lighthearted grin turning serious. He eyed Vax with newfound respect, his amusement fading as he straightened up. "Ever since I awakened, this is the first time I’ve felt even a twinge of pain," he admitted, his voice carrying a weight that hadn’t been there before. His eyes narrowed as he looked Vax over, sizing him up as if realizing for the first time that this fight might actually pose some challenge. "You're good."Vax’s confidence faltered for a brief moment, a crack in his usual calm demeanor. He took a step back, his grip tightening on the hilt of his sword, eyes flicking toward Klein’s glowing scales. His lips parted, but he hesitated before speaking, as if trying to brush off the growing tension. "What are you, some kind of monster?" His tone was playful, but there was an edge of real concern in his voice that he couldn’t quite hide. Drops of sweat trickled down his forehead, betraying the strain it was taking to keep his composure.Klei

Chapter: Durendal
“Yeah?” Klein said nonchalantly, a smirk tugging at his lips. “Maybe you should have taught your Vice some respect. He attacked a defenseless Blank inside a Dungeon Gate and left him for dead. What kind of example is that?”Vax's expression softened a little. “I admit, Manny was wrong,” he responded, and Klein was taken aback by Vax's unexpected reasonableness, making him slightly uncomfortable. “But you didn’t have to destroy my base and hurt my guildmates to deal with just one person.”Klein shifted his stance, feeling a flicker of guilt. Perhaps he had overreacted. “You’re right,” he acknowledged, rubbing the back of his neck. “I could’ve handled it differently. I’m not perfect, and I sometimes let my anger take over.” He met Vax’s gaze. “So, what happens now? Do you want an apology, or are you here to prove a point?”“No need for apologies,” Vax replied, his expression turning serious once more. “This is about honor and justice.” His voice was firm. “I challenge you to a duel. If

Chapter: Vax
Klein’s shout rang out through the courtyard, filled with fierce determination as he lunged at Manny, delivering a single, devastating punch. The impact was brutal, echoing like thunder as it connected with Manny’s face. The force of the blow sent Manny flying through the air, twisting and turning like a ragdoll caught in a storm. Dust and debris erupted around him, swirling chaotically as shockwaves rippled through the ground.Klein didn’t hesitate. He propelled himself into the air, effortlessly hovering above Manny’s airborne form, a predatory gleam in his eyes. As Manny reached the peak of his flight, Klein descended, slamming him back down with a force that shook the earth beneath them. The ground exploded into a crater upon impact, debris scattering everywhere and sending the surrounding knights reeling.A heavy silence fell over the Garrison Whites who remained conscious, their faces frozen in shock and disbelief. Manny, one of their esteemed commanders, had been defeated so ea

Chapter: Dragonic Damnation
Manny felt a surge of determination as he activated his System, the power coursing through him like wildfire. Without hesitation, his regular clothes evaporated, replaced by a full suit of Crimson Red Armor that shimmered with an intimidating brilliance as it settled over his body. The armor, with its sharp edges and intricate designs, pulsed with energy, radiating an aura of menace.“Crimson Armor!” he shouted, his voice booming and echoing through the courtyard. The Garrison Whites roared in approval, their excitement palpable as they formed a semicircle around him, eager to witness the impending confrontation.Klein simply smiled, his gaze unwavering as it locked onto Manny’s. He stood his ground, not flinching, not taking a step back. The confidence radiating from him made the onlookers uneasy. Some began to murmur amongst themselves, questioning Klein's sanity.“He wants to challenge a Vice?” one whispered in disbelief.“Pft, Manny will wipe the floor with this Blank,” another sc

Chapter: EIGHT
The heavy oak doors of the Valerius main lobby groaned as they were thrown open. Arthur Thorne marched in, flanked by a man in a sterile grey suit—Inspector Vane of the City Health Bureau—and a small army of private security. Behind them, the heirs of the Lee and Song families lingered, their faces twisted into masks of expectant triumph."Silas!" Arthur roared, his voice booming through the marble atrium. "The games are over. We have reports of unregulated biological hazards being processed on these premises. Step aside, or the Valerius Group will be shuttered by sunset."Silas stood at the base of the grand staircase, leaning heavily on his silver-topped cane. He didn't look like a man under siege; he looked like a man watching a play he had already seen. "Arthur, you seem remarkably energetic for a man who was a corpse four days ago. Is this how you thank the man who gave you back your breath?"Arthur flinched, his hand instinctively touching the spot on his chest where Kaelen had

Chapter: SEVEN
The Bone-Eater's bridge was less of a structure and more of a nightmare woven from petrified wood and the ribs of massive, long-dead swamp creatures. It spanned a gorge filled with a thick, churning sludge that bubbled with toxic gases. On the far side, the mist didn't just hang; it pulsed with a sickly violet light, signaling the edge of the grove where the Syndicate had set up their camp."He's waiting," Lyra whispered, her hand tightening on the hilt of her dagger.At the center of the bridge stood a man who looked like he had been carved out of grey granite. He was massive, shirtless despite the damp chill, and his skin was covered in a network of jagged, white scars that formed a map of a thousand survived deaths. He didn't carry a weapon. He didn't need one. His fists were the size of mallets, and his eyes were milky white, devoid of pupils."The Keeper," Kaelen muttered. He stepped forward, his boots clicking softly on the bleached bone-planks."Kaelen, wait," Elara called out,

Chapter: SIX
The preparation for the northern marshes didn't happen in a boardroom, but in the dim, herb-scented air of Kaelen's warehouse. While the city slept, Kaelen moved with rhythmic precision, grinding dried star-thistle and mixing it with a silver powder derived from his master's stores.Elara sat on a wooden crate, watching him. The humming energy he had injected into her veins the night before had faded into a dull, pleasant warmth, but her mind was sharper than ever."The logistics are handled," Elara said, her eyes following the movement of his hands. "We have a rugged transport vehicle and enough supplies for a week. But Silas is worried. He says the marshes aren't just a physical place—they're a graveyard for anyone who doesn't understand the 'breath' of the swamp."Kaelen stopped grinding and looked at her. "He's right. The Shadow-Fen is where the earth's energy becomes stagnant. It rots the spirit before it rots the body. Most people who go looking for the Heavenly Marrow Fruit end

Chapter: FIVE
The night air outside the Grand Azure Hotel was thick with the scent of impending rain. Kaelen walked down the marble steps, his pace steady, while Elara hurried to keep up, her heels clicking like rapid gunfire against the stone."You shouldn't have provoked Mingyu like that," Elara said, her breath hitching slightly. "His family controls the largest chemical distribution network in the province. They don't just fight with fists; they fight with lawsuits, supply chains, and... darker things."Kaelen stopped at the base of the stairs and looked back at the glowing spire of the hotel. "He was already a tumor, Elara. You don't negotiate with a tumor; you excise it. If I had stayed silent, he would have assumed I was weak. Now, he knows I am a threat. A threatened man makes mistakes."Before Elara could respond, a low, melodic whistle echoed through the parking lot. It wasn't a bird or a breeze; it was a sound that carried a sharp, metallic edge.Kaelen's eyes narrowed. He stepped in fro

Chapter: FOUR
The Azure Phoenix Needle felt warm against Kaelen's palm, its silver surface etched with microscopic runes that pulsed like a heartbeat. He sat in the center of the warehouse, the silence of the industrial district wrapping around him. With the needle returned, the air in the room felt different—more structured, as if the artifact itself was anchoring the energy of the space."You've been staring at that for an hour," Elara said, leaning against the doorway. She had changed into a dark silk blouse, her hair now down, cascading over her shoulders. She looked less like a corporate shark and more like a woman burdened by the weight of a dying empire. "Is it really that important?""In the right hands, this needle can restart a heart that has been cold for a day," Kaelen replied, not looking up. "In the wrong hands, it can turn a drop of water into a poison that kills an entire city. My master didn't lose it; it was stolen during a massacre. The fact that the Thornes had it means they we

Chapter: THREE
The three-day mark arrived like a guillotine.The Thorne mansion, usually a place of cold, calculated refinement, was now a scene of frantic, high-stakes chaos. Arthur Thorne lay sprawled across his silk sheets, his skin the color of wet ash. His chest didn't heave; it stuttered. Every breath was a jagged, rattling struggle that sounded like dry leaves being crushed under a boot."Where are they?" Arthur gasped, his eyes bulging as he looked at the expensive medical team surrounding him. "I pay you... millions... fix this!"Dr. Julian, the head of the medical team, wiped sweat from his brow. His hands, usually steady enough to perform micro-surgery, were trembling. The monitors displayed a jagged, erratic rhythm that defied every textbook he had ever memorized."Mr. Thorne, your vitals are... they're impossible," Julian stammered. "There's no blockage, no clot, no failure we can see on the scans. It's as if your heart simply forgot how to beat."Isabella Thorne, Arthur's daughter, sto
