The journey to Rust City took thirty-six hours of relentless trekking through the Howling Ravine, a canyon where the wind screeched through narrow fissures with the sound of a thousand dying banshees. For a normal Tier-1 professional, the jagged terrain and the constant acoustic assault would have induced madness. For Alex, it was merely another form of tempering.
He arrived at the gates of the city at dusk.
Rust City was a sprawling, vertical slum built into the husk of a crashed Pre-Great Change sky-fortress. Its walls were a patchwork of rusted steel, scavenged mana-plating, and glowing neon signs advertising black-market organs and forbidden spirit-liquor. The air was heavy with the smell of cheap fuel and ozone.
At the entrance, two hulking guards in exoskeleton suits scanned the newcomers. Alex kept his head down, his Cloak of Stone technique suppressing his aura until he felt like nothing more than a pebble in a stream of desperate humanity.
"Name?" the guard grunted, not even looking up from his tablet.
"Ash," Alex replied, using the first name that came to mind.
"Scavenger or Mercenary?"
"Looking for work."
The guard tossed him a dented brass token. "Entry fee is five hundred credits. If you don't have it, you have twenty-four hours to earn it before we sell you to the mines. Move along."
The Belly of the Beast
Alex stepped into the chaotic heart of the city. He needed information and, more importantly, he needed resources. The Dragon-Marrow Essence had catalyzed his breakthrough, but it had also left his body famished. His cells were screaming for high-density nutrients to stabilize his Viscera Tempering.
As he navigated the neon-lit alleys, he found himself standing before a massive, circular structure buried deep in the foundations of the fortress. A flickering sign above the entrance read: THE PIT.
The roar from inside was primal. It wasn't the polite applause of a university tournament; it was the bloodthirsty howl of a crowd that wanted to see bones snap.
"Welcome to the Pit, kid," a voice croaked from the shadows.
A small, middle-aged man with a mechanical eye and a tattered suit leaned against a pile of rusted crates. He smelled of tobacco and stale beer. "You look like you've got a bit of weight on you. Looking to bet, or looking to bleed?"
Alex looked at the man's mechanical eye. It was an old model, but it was scanning him with a frequency that made his skin prickle. "Who's asking?"
"The name's Barnaby," the man grinned, revealing a row of silver-capped teeth. "I'm a talent scout. Or a 'leech,' depending on who you ask. You don't look like a mana-user. You look like one of those 'Physical Hardliners.' Rare breed these days. Most of 'em die before they hit twenty."
"I need five hundred credits," Alex said, his voice flat.
Barnaby let out a wheezing laugh. "Five hundred? Kid, if you survive one round in the 'No-Limit' ring, you'll walk out with five thousand. Of course, the 'No-Limit' means the other guy can use magic, and you... well, you only have your hands."
"Lead the way," Alex said.
The No-Limit Ring
The interior of the Pit was a tiered arena carved directly into the bedrock. In the center was a sunken circle paved with reinforced concrete, stained dark by years of unwashed blood.
"Ladies and gentlemen! Scum and villains!" the announcer's voice boomed over the speakers. "Tonight, we have a fresh face! A wanderer from the wastes who thinks his fists are stronger than the stars! I give you... ASH!"
The crowd jeered. Alex stepped into the ring, the heavy iron gate clanging shut behind him. Across the circle, his opponent emerged.
He was a giant of a man, nearly seven feet tall, his skin covered in glowing blue tattoos that pulsed with elemental mana. This was Vorg the Vaporizer, a Tier-2 Fire-Bender who had been exiled from the military for "excessive cruelty."
"A brat?" Vorg sneered, his hands erupting into twin pillars of orange flame. The heat in the ring rose instantly, turning the air into a shimmering haze. "I'm going to turn you into a pile of charcoal before the first bell."
Alex didn't take a flashy stance. He simply stood there, his arms hanging loosely at his sides. He felt the eyes of the crowd on him, but more importantly, he felt the internal pulse of his Tempered Heart.
Thump... Thump...
"Kill him, Vorg!"
"Burn the trash!"
Vorg lunged. He didn't just throw a punch; he unleashed a Fire-Whip, a concentrated cord of plasma that lashed out with the speed of a strike. The whip cracked against the concrete, melting the stone instantly.
Alex moved.
He didn't dodge the whip; he stepped into the arc of the flame. The crowd gasped. To them, it looked like suicide. But Alex's skin, reinforced by the Star-Iron minerals and his Stage 5 bones, acted as a heat-sink. The fire licked at his chest, but instead of charring, his skin merely took on a dull, reddish glow.
[System Notification: Thermal Resistance absorbing 40% damage]
[Bone Density holding firm]
"What?!" Vorg roared, his eyes wide.
He unleashed a barrage of fireballs, but Alex waded through the inferno like a ghost. Every step Alex took cracked the concrete. The sheer weight of his presence was starting to suppress the oxygen in the ring, feeding the flames but starving Vorg's lungs.
"My turn," Alex said.
He bridged the gap in a single, blurring stride. He didn't use the Fist of Law-Breaking—that was too recognizable. He used a raw, unrefined haymaker.
BOOM.
The impact was like a sledgehammer hitting a melon. Vorg's fire-shield shattered instantly. The giant man was lifted off his feet and propelled across the ring, his body crashing into the iron bars with such force that the entire arena shook.
The flames died out. Vorg lay crumpled and unconscious, his blue tattoos flickering and fading.
The silence that followed was total. Then, the Pit erupted. It wasn't a cheer; it was a roar of greed.
Alex stood in the center of the ring, his dark hair singed but his eyes calm. He looked up at the VIP booths, where he could feel the gaze of the city's true power-brokers.
He had intended to hide. But as he looked at Barnaby, who was frantically counting a stack of credits, Alex realized that in a place like Rust City, the best way to hide a secret was to bury it under a mountain of noise.
"Next," Alex said, his voice carrying through the stadium.
