The rhythmic thump, thump, thump of the Guardian's footsteps echoed through the desolate bridge, shaking the very foundations of the Necropolis. Ren stood his ground, his silhouette dwarfed by the towering monstrosity of mismatched bones and rusted iron. The blue, spectral flames in the braziers flickered violently as the Guardian's aura—a mix of ancient death and stagnant mana—clashed with the raw, chaotic darkness radiating from Ren's mask.
[Warning: The Guardian of the Bone Gate (Level 15 - Elite) has locked onto Host.] [Detection: Host's Level is significantly lower. Survival probability: 15%.]
"Only fifteen percent?" Ren's voice, filtered through the Mask of False Divinity, sounded like the grinding of tectonic plates. He didn't feel fear. Instead, he felt a cold, analytical hunger. "That's more than I had when Aris threw me off the cliff."
The Guardian raised its cleaver. The weapon was a jagged slab of iron, stained with the dried blood of centuries. With a roar that shook the dust from the ceiling, the beast brought the blade down.
BOOM!
The obsidian bridge shattered where Ren had stood a split second ago. Ren didn't just dodge; he moved with a fluid, unnatural grace. The Void energy had rewoven his muscles into something denser, something faster. He was no longer a human knight bound by the laws of biology. He was a shadow given form.
[Skill Initiated: Shadow Dash.]
Ren turned into a streak of black mist, reappearing behind the Guardian's massive leg. He didn't use a sword—he used his bare hands, now coated in a shimmering layer of Abyssal energy.
"Let's see how many 'tolls' you've collected," Ren hissed. He plunged his hand into the Guardian's thigh, his fingers cutting through the reinforced bone like a hot knife through wax.
[Skill Activated: Soul Extraction (Passive).] [Extracting Essence...]
The Guardian let out a hollow, agonizing scream. It tried to kick Ren away, but the moment Ren's hand made contact, the shadows began to 'eat' the creature. The white bone turned grey, then black, then crumbled into ash.
The beast swung its cleaver in a wide, horizontal arc, forcing Ren to leap back. The wind from the blow was enough to bruise skin, but Ren landed softly on the edge of the bridge, his purple eyes glowing with a predatory light.
"You're just a pile of scrap held together by a weak soul," Ren taunted. He could feel the System working in the background, analyzing the Guardian's movements, calculating the structural weaknesses in its skeletal frame.
[System Insight: The core is located in the third vertebrae. Destroy the core to collapse the construct.]
"The third vertebrae... got it."
Ren didn't wait for the Guardian to recover. He lunged forward again, but this time, he didn't aim for the legs. He ran straight up the Guardian's massive cleaver, his boots clicking against the rusted metal. The beast tried to shake him off, but Ren's grip was absolute. He was a spider, a predator, a nightmare.
As he reached the Guardian's shoulder, the creature's ribs opened up like a cage, trying to trap him within its jagged interior. Ren didn't flinch. He summoned all the Void energy into his right fist. The air around him began to warp, the darkness becoming so dense it formed a miniature singularity.
"Abyssal... Impact!"
Ren punched straight into the center of the Guardian's chest. The explosion was silent but devastating. A wave of black force rippled through the skeleton, shattering the 'core' and sending shards of bone flying in every direction.
[Ding! Elite Enemy Slain: The Guardian of the Bone Gate.] [Exp +2,500. Soul Shards +50.] [Level Up! Level 2 -> Level 7.] [Skill Learned: 'Shadow Extraction' (Active).]
Ren landed amidst the heap of crumbling bones, his chest heaving. He felt a surge of warmth—no, heat—rushing through his veins. Every time he leveled up, the System re-optimized his body, purging the last remnants of his human frailty.
He looked at his hands. They were trembling, but not from exhaustion. It was a thrill. A high. He had just killed something that would have required a whole squad of Paladins to take down, and he had done it alone.
"Shadow Extraction..." Ren whispered the name of the new skill. "System, explain."
[Shadow Extraction: The Host can now pull the shadows from the fallen to serve as eternal soldiers. Current Limit: 1/1. Rank: Low.]
Ren turned his gaze toward the remains of the Guardian. A faint, wispy shadow was rising from the pile of bones. It looked like a smaller, more translucent version of the giant he had just killed.
"Arise," Ren commanded.
The shadow shuddered. It grew, solidifying into a dark, knight-like figure draped in a tattered black cape. It knelt before Ren, its head bowed in absolute submission. It didn't have a voice, but Ren could feel its loyalty—a cold, unyielding bond.
[Shadow Knight (Level 7) added to the Void Army.]
"Good," Ren said, a dark smile playing on his lips behind the mask. "One down. A world to go."
He turned toward the gate at the end of the bridge. It was no longer sealed. The heavy iron doors were swinging open, revealing a path that led deeper into the Necropolis—a place of winding tunnels, forgotten tombs, and ancient horrors.
Ren didn't feel like a prisoner anymore. He felt like an owner.
But as he took his first step into the next zone, a chilling sensation washed over him. It wasn't the cold of the Abyss. It was a feeling of being watched. High above, through the cracks in the cavern ceiling, he could almost feel the 'Light' of Elarion searching for him.
"Search all you want, Aris," Ren looked up, his purple eyes piercing the gloom. "The more you look for the light, the more you will fear the shadow I've become. I'm not just surviving down here. I'm building an army."
Ren walked into the darkness, followed by his silent shadow knight. The second circle of the Necropolis was waiting, and it was far more dangerous than the first. But for the man who had already died once, danger was just another word for opportunity.
