The air in Sector 8 was more than just a gas to be inhaled; it was a thick fluid of sulfur, copper vapors, and coal dust that the lungs had to forcibly masticate.
Elian Laurent trudged along, dragging his right foot through a narrow corridor where the walls wept with the condensation of engine lubricants. He spat a glob of blood-streaked saliva onto the iron grating beneath his feet. His left shoulder was now nothing more than dead weight—numb flesh and bone, throbbing with a torturous rhythm every time his heart pumped blood.
His brain, the biological supercomputer usually capable of dissecting reality, was silent. His Null Perspective was dark. The overhead impact from the previous battles on the train and in the boiler room had scorched his sanity. Now, whenever he tried to squint to find decimal errors in the air's variables, all he received were blinding flashes of white light and a fresh stream of blood trickling from his nostrils.
He was truly blind. Returned to being an ordinary human—mortal, fragile, and easily crushed.
"You know, for someone whose muscles were just hammered by a Kinetic Axiom-coated sledgehammer, you have a decent walking endurance," Caelus's voice broke the monotonous roar of the surrounding factories.
The mad poet walked behind Elian, his silver cloak seemingly repelling the filth of Sector 8. He was twirling a silver coin between his fingers with the agility of a street magician, while his left hand held the remains of an apple that, somehow, was still not finished.
Elian didn't answer. His red, weary eyes stared straight at the iron floor ahead. There, reflecting the unnaturally dim glow of the steam lamps, were several droplets of liquid. Silver blood. It was the trail of Lyra Vance, the Refraction Girl. The trail meandered, the droplets falling at shorter intervals, indicating their target was weakening.
"She's bleeding out. Her stride is shortening," Elian muttered hoarsely, his voice scraping against a dry throat. "She's moving north. Toward the disposal zone."
Their path led them out of the narrow corridor, ending at a partially collapsed metal balcony. The hot winds of Sector 8 immediately slammed into Elian's face, carrying the scent of wet rust. Before them stretched an industrial chasm a hundred meters wide. No bottom was visible, only a swirling vortex of black soot clouds and rotating orange vapors.
The only link to the Bell Tower complex on the far side was an ancient cable-stayed bridge. Its condition was precarious. The four main steel cables serving as its primary support were heavily rusted, peeling like the bark of a dead tree. Many of the iron floor plates were missing, revealing the gaping abyss below.
Yet, it wasn't the rust or the height that made Elian's instincts scream. It was the movement.
The bridge was alive. It swung up and down rhythmically, its cables groaning and screeching loudly.
THUMP... THUMP... THUMP...
The sound originated from the bottom of the chasm. The shockwaves surged upward through the air, vibrating the tips of Elian's boots. Down there, shrouded in fog, a massive hydraulic piston was working, pumping pressure to the city center. Every strike generated a vibration that traveled through the supporting cliffs and directly into the bridge's structure.
Caelus stopped spinning his coin. He tilted his head, his eyes narrowing at the dancing bridge. "A terrible harmony. This bridge is singing its own death song."
Elian bent down with great effort. He picked up a steel bolt the size of a fist from the floor, weighed its mass for a moment, and threw it in a curved trajectory toward the center of the bridge.
CLANG!
As the bolt struck the iron plate in the middle of the bridge, something horrific happened. The bridge's vibration did not subside; instead, it spiked sharply. The bolt was bucked into the air, and the oscillation of the bridge cables doubled in magnitude. The sound of tearing metal echoed from the anchor points on the cliff.
"Destructive resonance," Elian hissed, his eyes sweeping the length of the cables, manually calculating the tension within his aching brain. "The piston below... its vibration frequency is a perfect match for the natural frequency of this structure."
"And in the language understood by a poet like me?" Caelus asked casually, though his hand now gripped his white-gold harp, anticipating chaos.
"It means if we run across like idiots, our body weight and footfalls will add kinetic energy to the bridge's wave oscillation. The amplitude will increase indefinitely," Elian turned to Caelus, his eyes cold and undeniable. "We step, the bridge tears itself apart, and we fall into the depths of Sector 8's hell."
"A very un-aesthetic choice," Caelus smiled thinly. "So? Do we wait until the mountain-sized pump down there is turned off?"
"No. We break the rhythm."
Elian stepped to the edge of the abyss. He closed his eyes tight. He pushed aside the pain in his shoulder, suppressed the ache in his ribs, and focused all his remaining sanity on his ears. If he couldn't see the code of reality, he would listen to it.
THUMP. The piston strikes. The bridge swings up.
Pause. The piston retracts. The bridge swings down.
THUMP. The second strike. The interval was exactly 1.5 seconds.
"Listen to me, Caelus," Elian's voice shifted into absolute command. "We cannot step simultaneously. We must cancel this mechanical wave by creating interference. I will step on the odd beats, exactly when the bridge is thrown upward. I will suppress its momentum. You step on the even beats, at the nodes of the vibration."
Caelus did not argue. He smoothed his silver cloak and positioned himself a meter behind Elian. "Lead the way, Conductor. I'll keep the harmony of the beat behind you."
Elian took a deep breath, filling his lungs with the toxins of Sector 8. THUMP.
He stepped. His boot slammed into the bridge's iron plate just as the kinetic wave from below tried to hurl him upward. The collision of the two opposing forces was brutal. The shock didn't dissipate into the air; it traveled directly from his sole, up his shin, and exploded in his cracked ribs.
Elian spat fresh blood from between his teeth, but his legs did not falter. He braced his weight, acting as a living shock absorber.
Pause. Caelus stepped behind him. Light, silent, at the exact millisecond the bridge cables were in a neutral position.
THUMP. Elian stepped again. Impact. Blinding pain. He forced his legs to move against the natural rhythm of the human body. His steps were staccato, rigid, and lethal. Below him, the disposal chasm yawned, waiting for a single decimal error in his brain.
In the middle of the bridge, the torment reached its peak. The winds of Sector 8 roared, swaying them from side to side. The iron floor plate beneath Elian shrieked, nearly snapping as he pressed down to counter the resonance wave. Sweat mixed with oil dripped from his chin. His vision dimmed, surrounded by black spots.
Yet his mouth continued to murmur like a madman's mantra, "One... suppress. Three... hold. Five..."
He didn't know how long he had been a bleeding metronome. But when the soles of his boots finally felt the texture of solid, unmoving concrete, his defenses crumbled.
Elian fell to his knees at the edge of the opposite cliff. He clutched his chest, coughing so hard it felt as if his lungs would burst. Caelus landed beside him, his cloak fluttering with annoying elegance, looking entirely unfatigued.
Behind them, the bridge still swayed, but it slowly subsided into its normal oscillation, having failed to tear itself down.
"A rather crude harmonic resolution, but not bad for a beginner," Caelus commented, brushing imaginary dust from his sleeve.
"Cough... shut up..." Elian forced his head up, searching for the trail of silver blood.
"Your shoulder is slanted, Mister. You're bleeding, too."
The voice was so small, so high-pitched, and so out of place. Elian flinched, his hand instinctively reaching for his belt for a weapon. Behind the shadow of the bridge's concrete support pillar sat a young girl, cross-legged.
She was perhaps only ten or eleven years old. She wore an oversized mechanic's jumpsuit that had faded to a dirty gray, riddled with haphazard patches. Her face was smudged with oil and soot—typical of the countless scavenger street kids in Sector 8. In her hand, she was boredly spinning a rusted bolt. A cheap copper plate engraved with the name 'Aria' hung loosely around her neck.
In this place, where the air could kill you and the machines could chew you up, this child seemed utterly irrelevant. Utterly trivial.
Aria held out her left hand toward Elian. In her tiny palm was a piece of hard bread, its color so dark it looked more like pumice than food.
"Take it," Aria said, her voice flat, devoid of any fear toward the blood-soaked man in front of her. "I found this near the smelter workers' canteen trash bin this morning. You're pale. You're hungry, right?"
Elian stared at the bread. His street instincts knew that in the Lower Sectors, refusing food was idiocy, no matter how grim it looked. His body needed absolute carbohydrates to keep his brain from starving after that extreme calculation.
"You're hurt, too," Aria noted Elian's slumped shoulder with a dull, innocent gaze. The little girl reached into her jumpsuit pocket and pulled out a small glass bottle filled with a thick black liquid and a roll of yellowed, dirty cloth bandages. "This is used gear lubricant. If you mix it with dust, it can seal a wound so it doesn't get infected. Old mechanics use this when their hands get cut by the machines. Want me to fix you up?"
Hearing the offer of treatment with used oil and dirty rags, Elian shook his head quickly. His wound needed care, but an infection from Sector 8's industrial filth would kill him much faster than the bleeding itself.
"I don't need the treatment, kid," Elian said, his voice hoarse, but his cynical tone softened for a moment in the face of a fellow child of the Lower Sectors. He snatched the hard bread from Aria's hand. "But I'll take the bread. I'm in a very big hurry."
Elian bit into the wood-hard bread, forcing it down his throat. "Thanks, Aria. Don't hang around here; it's not safe," he said as he forced himself to stand, not wasting another second.
Elian began to run haltingly toward the shadow of the giant tower in the distance. Caelus followed behind, giving only a single fleeting glance at the child before returning to spinning his coin, entirely indifferent.
Beneath the shadow of the pillar, Aria remained sitting cross-legged. She didn't disappear or transform into a mysterious entity. She simply shrugged her small shoulders, put the dirty lubricant bottle back into her pocket, and resumed spinning her rusted bolt on the concrete floor—appearing like an extra the world would forget by tomorrow morning.
The old Bell Tower was an industrial graveyard. Towering like the ribcage of a rotting steel monster, the place was used to pile up scrap machinery that even the Rust Ravens were reluctant to salvage.
Elian entered through the main gate, its hinges having melted years ago. The interior of the tower was vast and circular, with dirty orange light piercing through broken stained-glass windows in the high ceiling.
On the concrete floor, rust dust had accumulated ankle-deep, creating a red carpet that smelled of iron blood. And on that carpet of dust, the trail of Lyra's liquid mercury blood stopped dead in the center of the room.
Elian scanned the surroundings. Piles of massive gears, broken chains, and shattered engine blocks. Empty. No signs of life. Not even the sound of breathing.
"Decent optical magic," Caelus whistled softly, leaning against the stone doorframe. "She's bending the refractive index of light around her body to blend into the background. Unless you have your anomalous vision, she's invisible."
"I don't need anomalous vision to understand basic physics," Elian hissed. His hand tightly gripped a long iron pipe lying near his feet. His weary eyes stared at the calm expanse of rust dust before him.
"Optical illusions can indeed bend light, manipulating what the retina captures," Elian murmured coldly, slowly rotating his body, seeking the right angle. "But illusions cannot erase mass. Two objects with mass cannot occupy the same space."
Without warning, Elian kicked a thick mound of rust dust near an engine block with all his might.
ZRAASH!
A cloud of deep red particles scattered into the air, exploding like a rusted smoke bomb, sweeping across a three-meter-wide empty space in front of him. Time seemed to slow as gravity began to pull the dust back down.
Most of the dust fell straight to the floor.
However, in one corner, two meters from Elian's position, an anomaly occurred. The red dust particles stopped in mid-air. They didn't fall. The rust dust clung to something invisible—coating the curve of a shoulder, seeping into the folds of an imaginary cloak, and printing a clear silhouette of a human crouching and clutching their arm.
The empty space now had a form, painted red by physical rust.
"Found you," Elian growled.
He lunged forward, using the last of the strength in his legs, and leveled the sharp, broken end of the iron pipe straight ahead, stopping just a centimeter from the silhouette's neck.
The air distortion around the figure vibrated violently before finally shattering like glass hit by a hammer. The camouflage fell away.
Lyra Vance was fully revealed.
Her silver-white hair was disheveled and covered in dust. Her gray eyes were wide, radiating the shock and alertness of a cornered wildcat. Her left hand was soaked in silver blood that continued to drip onto the floor, while her right hand quickly reached for her belt, prepared to draw whatever lethal weapon she was hiding.
"Hand over that Grand Cipher, now," Elian threatened, the tip of his pipe nearly touching the skin of Lyra's neck. The girl gritted her teeth, the veins in her neck tensing, preparing to fight back even though she knew she was dying.
However, before a single word could escape Lyra's lips—
BLAAAAARRRR!!!
The stained-glass ceiling of the Bell Tower exploded inward. Hundreds of glass shards as sharp as daggers rained down on them like a crystal storm. Lyra instinctively covered her face, while Elian leapt back to avoid the debris.
The deafening clang of giant metal echoed as four steel chain anchors weighing dozens of tons slammed into the tower floor from above, crushing piles of scrap and trapping them in the center.
BEEP... BEEP... BEEP...
A military siren wailed high. Blood-red spotlights, blindingly bright, pierced through the holes in the ceiling and windows, sweeping the entire room and locking Elian, Lyra, and Caelus in an executioner's circle of light.
From behind the dusty wreckage of the main gate, the sound of metal footsteps approached. Extremely heavy. Extremely slow. Every step made the tower's concrete floor vibrate.
White smoke billowed from the threshold. A giant nearly two and a half meters tall stepped inside. His body was encased in steel plates welded directly to his skin. From his mechanical nostrils, hot steam hissed. The Bloodhound.
The Rust Ravens' chief executioner did not smile. His glowing red eyes swept over his three victims with a merciless gaze. High-level Kinetic Axiom, a dense yellow, radiated wildly from his steel fists, creating sparks of static electricity that scorched the air.
"A Sector 9 rat who refuses to die. A Mad Poet who talks too much. And a Military Fugitive Ghost," The Bloodhound's voice growled low, echoing throughout the engine graveyard. He slammed his fists together in front of his chest. The shockwave swept the dust on the floor, making Elian's chest feel even tighter.
"What a beautiful coincidence. I will break every one of your bones, one by one, just to see where your greatness lies."
Around the tower, from every gap and window, dozens of fully armed Rust Raven thugs appeared, surrounding them, leveling various energy barrels and bladed weapons at the three of them.
Elian glanced back. A dead end. He glanced at Lyra, whose breathing was growing heavier, then at Caelus, who for the first time, had stopped spinning his silver coin.
They were completely surrounded. This coffin had just been sealed shut.
