The Lower Smelting Pits of the Imperial Academy did not look like a place of learning. They looked like the belly of a dying volcano.
Located a half-mile beneath the polished marble floors of the Noble Spire, the Pits were a sprawling, subterranean network of cavernous workshops. The air was a suffocating soup of sulfur, coal dust, and ambient heat that hovered around a hundred and twenty degrees. Massive, Qi-powered trip-hammers pounded rhythmically in the gloom, their deafening impacts shaking the bedrock every few seconds.
Squad 7 stood at the entrance of Sector 4, dressed not in their Academy uniforms, but in coarse, heavy leather aprons and thick heat-resistant gloves. They looked entirely out of place, especially Princess Zhao Yan, whose pristine violet aura was currently struggling to repel the thick layer of soot already settling on her face.
Standing before them, holding a clipboard made of iron, was Master Helga. The dwarven-sized Forgemaster looked Kai up and down, her eyes lingering on the heavy Density-Stone cuffs locked around his wrists.
"I remember you, Hart," Helga grunted, her voice barely cutting through the industrial roar of the cavern. "You've got the 'Touch.' But Vice-Dean Kael's orders were crystal clear. You aren't here to craft. You aren't here to forge. For the next three days, Squad 7 is nothing but a team of two-legged mules."
Helga pointed a thick, calloused finger down the long, sweltering corridor of open-air forges. There were over fifty senior Academy blacksmiths working at their anvils, shouting orders over the din.
"These smiths are forging the vanguard weapons for the third-year border deployments," Helga explained, her tone devoid of sympathy. "They don't stop hammering. If they run out of coal, you fetch it. If they need Cloud-Iron ore crushed, you crush it. If they need a quenching trough refilled with ice-water from the lower aquifers, you carry the buckets. You run until your boots melt or the shift bell rings. Understood?"
"Yes, Master Helga," Kai replied, his voice a metallic rumble.
"Princess," Helga added, shooting a sideways glance at Yan. "Down here, royal blood just boils faster than common blood. Leave your attitude at the door, or the senior smiths will toss you in a slag pit."
Yan's jaw tightened, her violet eyes flashing with indignant fury, but she forced a sharp nod. "Understood."
"Then get moving!" Helga barked. "Forge Seven needs two hundred pounds of refined coal, and Forge Twelve needs their Cloud-Iron sorted!"
The first day was not a test of cultivation; it was a test of basic human survival.
Within the first hour, the sheer physical reality of their punishment set in. They weren't fighting a monster, where adrenaline and a few well-placed strikes could end the encounter. They were fighting gravity, heat, and endless repetition.
"Hey, fresh meat!" yelled a burly, soot-covered third-year student from Forge Nine. "I need fifty pounds of raw flux and a new pair of tongs! Move it!"
"On it," Maya grunted. Her forearms were still wrapped in medical bandages from the Wyrm's breath attack, making every lift agonizing. Yet, the sturdy Earth-affinity commoner simply gritted her teeth, hoisted a heavy sack of chemical flux over her uninjured shoulder, and jogged toward the senior student.
Robert was faring much worse. The Void-affinity thrived in cold, empty spaces. The dense, hyper-active heat of the Smelting Pits was making him nauseous. He was dragging a heavy wooden cart filled with quenching-oil across the uneven stone floor, his breathing shallow and erratic.
"I'm going to throw up," Robert wheezed, pausing to lean against the cart. "I survived a Tier 7 Wyrm just to die of heatstroke in a basement."
"Keep moving, Vance," Yan snapped, marching past him with an eighty-pound iron crate of raw ore in her arms.
Kai stopped what he was doing and stared.
Princess Zhao Yan, heir to the Imperial House, was carrying a crate of dirty rocks. Her aristocratic face was completely smeared with black soot. Her intricate, braided hair was coming undone, sticking to her forehead with sweat. Her arms were trembling under the weight, but her violet eyes burned with absolute, stubborn refusal to drop the crate. She was using her Tier 1 (Mid) Qi not to fight, but simply to keep her spine from snapping under the manual labor.
"Princess," Kai said, stepping into her path. "Let me take that. Your muscles aren't conditioned for—"
"Do not insult me, Hart," Yan hissed, her voice venomous, though she was panting heavily. She glared up at him, her molten-gold eyes meeting her violet ones. "Kael wanted to break my pride. He wanted to see the Princess cry over blistered hands. I will carry this crate if it kills me."
Kai slowly stepped aside, a profound sense of respect settling into his chest. "Forge Twelve is twenty yards ahead. Watch your footing on the slag."
Kai was assigned to the heavy lifting. With his Strength at 23 and Endurance at 24, fueled by his Minor Cleansing, he was the only one in the squad who could keep up with the demands of the heaviest anvils.
But Kai had a handicap. The damaged Density-Stone Cuffs were still locked to his wrists and ankles, actively pulling him down with a fluctuating 2x gravity draw. Every hundred-pound crate of Cloud-Iron he carried effectively weighed two hundred pounds. Every step he took across the sweltering floor felt like walking through waist-deep mud.
[System Alert: Extreme Environmental Strain]
[Stamina drain at critical levels. Minor muscle tearing detected.]
"Boy! Over here!" bellowed a massive, bare-chested senior blacksmith at Forge Three. "I need the quenching trough swapped! Now!"
Kai jogged over, the iron chains of his cuffs clinking. He grabbed the edges of the massive, cast-iron water trough—which easily weighed four hundred pounds full—and hauled it away from the furnace, replacing it with a fresh one.
As Kai stepped back to wipe the stinging sweat from his eyes, he didn't immediately run to the next task. He lingered for a few seconds in the shadows. He wasn't allowed to touch a hammer, but Kael hadn't forbidden him from watching.
Kai activated his [Appraisal] skill.
He watched the senior blacksmith pull a glowing, white-hot ingot of spirit-steel from the forge. The smith didn't just smash it with a hammer. He took a specific breath, channeling a pulse of Water-affinity Qi into his shoulders, and struck the metal at an exact, forty-five-degree angle.
Clang. Clang. Clang.
Kai's molten-gold eyes tracked the flow of the senior student's Qi. He watched how the impact forced the microscopic impurities out of the steel, while the Water Qi instantly cooled the surface, locking the molecular structure into place before the next strike.
[System Alert: Observation Successful]
[Apprentice Forgemaster Proficiency increased by 5%.]
[New Technique Identified: Thermal-Shock Hammering.]
Kai smiled grimly. He was a mule, yes. But he was a mule with a photographic memory for elemental resonance.
Over the next three days, Kai ran himself ragged. He carried tons of coal, hauled gallons of blistering acid, and swept up piles of razor-sharp iron slag. But every time he delivered a material to a senior smith, he spent three seconds memorizing their hammer swings, their Qi flow, and their tempering methods. He was stealing a third-year Academy education entirely through observation.
By the final hour of the third day, Squad 7 looked like casualties of war.
They were collapsed in a dark, slightly cooler corner of Sector 4, sitting on a pile of empty coal sacks. The incessant, deafening pounding of the trip-hammers faded into the background as the shift-end bell finally rang.
Robert was lying flat on his back, staring blankly at the cavern ceiling, completely non-responsive. Maya was methodically unwrapping the ruined, soot-stained bandages from her arms, her jaw set in a tight line.
Princess Yan sat with her knees pulled to her chest. Her royal hands, which had previously only handled delicate alchemical herbs and silver tea sets, were covered in ruptured blisters and embedded coal dust. She was silently staring at her palms.
Kai sat across from her. His upper body was covered in fresh, minor burns from flying sparks, and his muscles twitched involuntarily from complete exhaustion.
"We survived," Maya rasped, tossing her ruined bandages aside.
"I'm never complaining about the courtyard again," Robert wheezed from the floor. "I will kiss Vice-Dean Kael's stupid wind-stairs if it means I never have to smell sulfur again."
Yan slowly lowered her hands. She looked at Robert, then at Maya, and finally at Kai. The aristocratic arrogance that had defined her since the entrance exam was gone, burned away by the heat of the forge and the shared misery of manual labor.
"Hart," Yan said, her voice hoarse from the smoke.
"Princess," Kai replied, resting his forearms on his knees.
"I..." Yan hesitated, the words clearly tasting like ash in her mouth. She took a deep breath. "I was a fool in the Canyons. I jeopardized the squad for a harvest. And... I could not have carried those crates today if Maya hadn't discreetly shifted the weight with her Earth Qi when the overseers weren't looking."
Maya snorted, looking away. "You're a twig, Princess. Didn't want you snapping and dropping ore on my boots."
"Thank you," Yan said softly, the sincerity in her voice shocking all three of them. She looked at Kai. "Kael was right. We aren't ready for the Outer Fringe. But we survived the Wyrm, and we survived the Pits. We held the line."
Kai nodded, a profound sense of camaraderie finally settling over the mismatched squad. They had been forced together by a cruel system, but the crucible had melted away the class divide. They were just four exhausted initiates who refused to break.
Master Helga's heavy boots echoed as she approached their corner. She looked down at the four miserable, filthy students. She reached into her apron and tossed a small, heavy leather pouch at Kai. He caught it.
"Your frozen accounts have been released by the Vault," Helga grunted. "One thousand credits each, minus the extraction penalty. You paid your debt, mules."
Helga turned to walk away, but she paused, looking back over her shoulder at Kai. "Oh, and Hart?"
Kai looked up.
"Your shift is over," Helga said, a subtle, knowing gleam in her eye. "Meaning you aren't on punishment detail anymore. And Forge Twelve just happens to be empty for the next three hours. It would be a real shame if someone left the bellows running and an anvil unattended."
Kai's molten-gold eyes flared with sudden, intense heat. The exhaustion in his muscles vanished, replaced by the surging thrill of his Forgemaster class.
"Go to the dorms, guys," Kai said, standing up and gripping the hilt of the Quintessence Blade. He had one thousand credits, a massive chunk of premium Cloud-Iron, and a dozen new hammer techniques stolen from the upperclassmen burning in his mind. "I have an engine to upgrade."
