Chương 20: CHAPTER 18: THE RUNIC NERVE STITCH

The scent of burning iron and raw alcohol filled the small stone chamber, thick enough to choke a normal man. Rudra sat on the edge of the rough stone cot, his jaw locked so tightly his back teeth threatened to crack under the immense pressure. He was stripped to the waist, his lean chest covered in a layer of grime, ash, and cold sweat.

His right arm—the dominant hand that had once executed flawless, micro-millimeter surgical incisions back in his past life—remained a useless, agonizing bundle of charred flesh and green medicinal paste, bound tightly to his torso like a broken wing. His focus, however, wasn't on his injuries. His wide, bloodshot eyes were entirely locked onto his left shoulder, where Thrain was currently aligning a heavy, jagged piece of dark dwarven engineering.

The prosthetic device wasn't a masterpiece of elegant, high-tier elven craftsmanship. It was a crude, massive hunk of black volcanic iron, exposed copper wiring, and miniature runic gears that hissed loudly, venting tiny plumes of trapped steam into the damp air. The metal surface was intentionally left unpolished, showing the raw, brutal hammer marks of the forge.

At the base of the heavy shoulder socket, where the machine was meant to interface with living anatomy, a dozen long, needle-sharp silver spikes protruded like the fangs of a mechanical beast. These were runic conduits, specifically forged to pierce flesh, bypass muscle, and anchor directly into a biological nervous system.

"Listen close, human brat," Thrain rumbled, his voice echoing off the narrow walls like low thunder. He wiped a massive, soot-stained hand across his heavy leather smithing apron, leaving a streak of grey grease. He picked up a clay bottle of clear, bubbling dwarven moonshine and poured it directly over the silver spikes. The high-proof alcohol sizzled violently against the magically heated runes, sending up a pungent, stinging vapor that made Rudra's eyes water.

"This isn't legendary craftsmanship. It's cheap iron. It'll give you a working fist so you can survive my training, but human meat rejects basic metal over time. The runes will keep the connection alive, but they'll slowly eat away at your remaining nerve endings. You've got exactly sixty days. If you don't find high-tier magic metals like Mythril or Adamantite deep in the dangerous ravines to replace this junk, your entire arm will permanently rot away right off your shoulder."

Rudra stared at the cold, waiting iron. Sixty days. A literal ticking clock attached directly to his skeleton." Saala, ek toh pehle se haath kharab tha, ab dusre mein bomb laga rahe hain," (Dude, one hand was already bad, now they are planting a bomb in the other one.) He thought, a dark, self-deprecating smile tugging at the corner of his lips. He had come to this world looking for a quiet, comfortable vacation where his system cheat codes would do all the heavy lifting.

Instead, he had sixty days to go from a crippled apprentice medic to a warrior strong enough to raid a monster-infested volcanic ravine.

The psychological pressure was suffocating, but instead of breaking him, it acted like an anvil, shaping his scattered panic into a single, sharp resolve.

"Do it," Rudra said, his voice flat, hollow, and completely unyielding. Thrain let out a grim grunt of approval, the amber glow in his yellow eyes shifting into something resembling respect.

"Hold onto your soul, kid. Don't swallow your tongue." Two massive, silent dwarf assistants stepped out of the shadows, their tree-trunk arms instantly pinning Rudra's shoulders back against the reinforced stone backrest of the cot. Rudra didn't even try to struggle. He braced his boots against the floorboards, watching as Thrain grabbed the iron prosthetic with both hands, his knuckles popping under his immense strength.

The Chief Vanguard lined the silver spikes up with the raw, exposed nerve clusters at Rudra's left shoulder joint. This content has been misappropriated from Royal Road; report any instances of this story if found elsewhere. Then, with the brutal, unyielding force of a hydraulic press, Thrain shoved the metal arm forward.

"AAAAAAHHHHHH—!" A scream of pure, unadulterated agony tore from Rudra's throat, shattering the silence of the chamber and echoing violently off the volcanic stone walls. It didn't feel like a normal puncture wound; it felt like a bolt of cosmic lightning had been violently driven into his shoulder joint, fracturing into a thousand jagged pieces inside his central nervous system.

The silver spikes tore through his skin, sliced through the underlying muscle fibers, and scraped agonizingly against his collarbone before locking directly into his deep nerve pathways. The exposed copper wires sizzled and popped as they made contact with his internal mana currents, drawing thick, dark blood that instantly vaporized against the hot iron casing of the prosthetic. The sheer sensory overload was terrifying.

Every nerve ending in his body fired at once, telling his brain that he was being dismantled piece by piece. Inside his head, the system didn't just chime—it erupted into a chaotic, glitched storm of blood-red alert windows that flashed wildly across his vision.

[CRITICAL FOREIGN OBJECT INTRUSION DETECTED!] [Unsanctioned biological-mechanical integration in progress.] [Warning: Severe neural shock imminent. User consciousness at risk of permanent collapse.] [Initiating emergency safety bypass... System attempting to sever sensory input to stabilize host.] Rudra's vision went entirely white, a blank void of pain where he couldn't even feel the breath in his lungs. His heart hammered so violently against his ribs he could feel the pulse vibrating in his teeth.

In that white void, the trauma of the horse cart massacre flashed through his mind again—the sight of the innocent family being cut down by bandit blades while he stood frozen, weak, and entirely useless. The memory didn't make him despair; it filled him with a monstrous, terrifying rage. No! he roared internally, his mind screaming against the dark. I will not be weak again! I will not sit by and watch people die because my hands can't move! I will not die in the dirt!

Using every single ounce of his fractured willpower, Rudra mentally smashed through the system's emergency shutdown protocol, refusing to let the interface put him to sleep." Don't you dare shut down! Override safety parameters! Forcing manual calibration! Map the runic signals straight to my motor cortex! Map them now!"

The system groaned under the weight of his furious mental command, the red translucent windows flickering erratically like a dying television screen before a fast-paced sequence of new code began to stitch itself across his eyes.

[User overrides safety protocols. Forcing neural calibration...] [Analyzing Dwarven Runic Arrays... Compiling data pathways...] [Integrating Low-Tier Dwarven Prosthetic (Iron-Grade)... Success.] [Current Synchronicity Rate: 42%... 61%... 78%.] [Warning: Structural degradation active. Ticking Clock initiated: 59 Days, 23 Hours, 59 Minutes remain until Neural Necrosis.] The white-hot agony slowly receded, morphing into a dull, throbbing, rhythmic roar that matched the sound of the forge hammers outside.

Rudra slumped forward against the leather restraints, gasping violently for breath, streams of sweat and dark blood dripping from his chin onto the cold stone floorboards. His muscles were twitching, his veins bulging against his skin from the forced mana integration. He slowly, carefully lifted his left side. The internal gears in the dark iron shoulder turned with a low, heavy mechanical click, puffing out a tiny cloud of white steam. He looked down at his new appendage.

His perfectly healthy, real left hand was now completely encased inside a blocky, four-fingered iron claw—heavy, cold, and imposing. As he flexed his fingers mentally, the copper wires pulsed with a faint blue mana light, and the mechanical gauntlet snapped shut into a tight, terrifying fist with a heavy metallic clank. It was clumsy, and it lacked the micro-precision of his original hands, but the crushing force inside that iron fist was undeniable.

Thrain stepped back, taking a long, slow drag from his iron pipe and letting out a rare whistle of genuine surprise. He had supervised the runic nerve stitch on hardened dwarf warriors who had broken down into weeping messes or passed out from the sheer shock of the runic spikes entering the bone. Yet this fragile, soft-skinned human brat had not only stayed entirely conscious, but had somehow forced the alien machinery to calibrate and stabilize in a matter of minutes.

"You're an absolute maniac, kid," Thrain said, his gruff voice carrying a new tone of unshakeable respect. He tossed a heavy, grease-stained rag onto Rudra's lap.

"Clean the blood off your face and stand up. You survived the forge, but don't get arrogant. Take your new toy and come out to the main cavern. The real hell begins now." Rudra wiped the sweat from his eyes with his new iron gauntlet, the cold metal pressing against his hot skin. He looked toward the open iron door, where the roaring orange light of the volcanic furnaces waited for him. The countdown was ticking. He had sixty days to conquer the dark, and he wasn't going to waste a single second.
