The air grew heavier with every step.

  Mushglow Hollow fell behind them in a fading sea of teal. The bioluminescent caps thinned along the tunnel, replaced by stone that gleamed faintly red, as if someone had painted heat into the rock and forgotten to let it cool.

  Steam hissed from narrow vents in the floor and walls. Not the lazy breath of the first chamber, but sharp, focused jets that came in short bursts. Each exhale left a faint white crust where it kissed the stone, like salt around a pot that had boiled too long.

  James wiped his forehead with the back of his wrist out of habit, then frowned slightly when there was no real sweat to clear.

  “Congratulations,” Gerrard muttered behind him. “We have discovered the world’s most aggressive sauna.”

  “It is not that hot,” Vhara said.

  Her breath came easy, shoulders steady under her armor. The heat rolled off her like a suggestion she had chosen to ignore.

  Mira, by contrast, looked like a boiled dumpling. “My hair is frizzing,” she said. “This alone is grounds for hazard pay.”

  James touched the wall as they passed. Heat soaked into his fingertips, present but controlled, not enough to burn, just enough to register.

  Veins of darker stone threaded through the red, glossy and faintly iridescent surface. In some places they had gathered into knots, like someone had pressed hot coals into the rock until it accepted them.

  He squinted. “That is new.”

  [Culinary Insight Activated]

  No ingredient detected.

  Additional Scan?

  “Yes,” he murmured under his breath.

  [Environmental Scan Activated]

  Material identified: Heatstone Ore (Unrefined)

  Properties: Stores and radiates thermal energy. Naturally forms near sustained mana furnaces or high temperature magical fauna.

  Uses: Smithing, enchantment foci, improvised cookware, overconfident architecture.

  Advisory: Prolonged contact may cause burns to non-attuned organisms. Do not lick.

  James grinned. “Heatstone. Lovely.”

  Gerrard squinted at the wall. “I see rock. You see revenue.”

  “I see context,” James said. “You do not get this kind of mineralization without something down here running hot for a long time. Like an oven that never turns off.”

  Mira bit her lip. “You mean the mid-boss.”

  “Probably,” James said. “Or something that acts like a mid-boss even if the system has not written a name tag yet.”

  He walked a little slower, eyes following the pattern of the ore. It grew thicker as they descended, the red stone darkening to a deep rust, veined with black. Moisture still clung to the ceiling but the drips sizzled when they hit the ground.

  The jar of Glowspore Mites at his belt glowed softly, the tiny creatures bumping against the glass with slow irritation. The Mushglow Caps in his inventory sat in mental slots, waiting.

  Mira caught him glancing at the jar. “You are thinking again,” she said warily.

  “I try not to make a habit of it,” James said. “Brain activity burns calories.”

  “What now?” Gerrard asked. “I should prepare myself emotionally.”

  “Glowspore broth,” James said.

  Vhara looked over her shoulder. “Explain.”

  He lifted the jar a little so the pale light brushed his fingers. “We have bioluminescent mites that shed mana rich dust. Mushrooms that are edible and mildly hallucinogenic when raw. We are in a dungeon that is only getting hotter. That means dehydration, exhaustion, heat sickness, maybe burns for most people. We want something that hydrates, stabilizes, and takes advantage of the environment instead of losing to it.”

  “Water,” Gerrard said. “It is called water.”

  “Water is step one,” James said. “Broth is water that has gone to university.”

  Mira frowned. “Broth as a stimulant?”

  He nodded. “Salt for hydration, fat for stamina, proteins for recovery. If I simmer Glowspore Caps long enough, the wobblier side effects should cook off, leaving mana trace and a bit of gentle clarity. Add mite dust at the right stage and we might get a mild boost to reaction time or perception. Nothing wild. Just a nudge in the right direction.”

  “You are guessing,” Vhara said.

  “Educated guessing,” James replied. “The best kind.”

  Gerrard eyed the vents as another jet of steam hissed out. “And you want to drink glowing mushroom soup before we fight unknown creatures that already live here.”

  “Yes,” James said. “After we test the first batch on myself.”

  Mira stared. “Of course you will be your own lab rat.”

  “Chef,” he corrected. “Lab chef.”

  “You are already planning another recipe,” Gerrard said. “Do you remember the last time you experimented with monster products? We all danced like lunatics in the inn with no music.”

  Another pulse of heat rolled through the tunnel, this one strong enough to make the hairs on Mira’s arms stand.

  James sobered. “Jokes aside, something down there loves heat. The ore proves it. We should assume fire or steam based attacks at minimum. A broth that warms from the inside in a controlled way might help bodies handle sudden spikes from outside. Like stepping from a warm room into a hot one instead of from a glacier into an oven.”

  Vhara considered that in silence.

  “Heat conditioning,” she said slowly. “Warriors used to do that near lava fields. Train close enough to tolerate, far enough not to die.”

  “Exactly,” James said. “Only we cheat with soup.”

  This narrative has been unlawfully taken from Royal Road. If you see it on Amazon, please report it.

  Mira sighed. “Fine. Soup training. But if I see colors that do not exist, I am blaming you.”

  “That is fair,” he said.

  The tunnel bent left, then dropped more steeply. The hum under their feet grew louder, deeper. The Mushglow light faded almost completely, leaving only the red shimmer of Heatstone and the pale glow of the mite jar.

  “Hold,” Vhara said quietly.

  They stopped.

  She dropped into a half crouch, fingers brushing the ground. Her eyes traced faint scratches near a vent, shallow grooves where the hot stone had been disturbed.

  “Tracks?” James asked.

  “Yes,” she said. “Claws. Small. Many feet.”

  Mira swallowed. “Please say rodents.”

  “Rodents do not usually leave scorch marks,” Gerrard pointed out.

  The steam vent beside them exhaled again. This time, along with the white cloud, there came a faint hiss that was not the stone.

  Something moved in the plume.

  “Back,” Vhara snapped.

  James jerked one foot away an instant before a small shape shot out of the vent, using the steam burst for sudden acceleration.

  It landed where his ankle had been, claws skittering on the hot stone. More followed from neighboring vents, each form riding a fresh burst of vapor. They scattered across the tunnel with unnerving coordination, fanning out to encircle the party.

  They were lizards, roughly the length of James’s forearm, with narrow bodies and sturdy legs built for gripping stone. Their scales shimmered from dark gray at the back to deep red along the belly, each scale edged with faint white lines like dried salt. Thin plumes of steam curled from their mouths every time they breathed. Along their spines, small vents opened and closed, exhaling tiny jets that helped them pivot faster.

  Their eyes were bright gold, pupil slits thin and sharp.

  One of them tasted the air and hissed, revealing needle teeth. A faint glow burned beneath its tongue.

  The system chimed.

  [Culinary Insight Activated]

  Steamfang Lizard

  Threat Level: Moderate.

  Behavior: Territorial pack hunters. Ambush from heated vents. Prefer soft targets.

  Attacks: Heated bite, steam bursts, coordinated lunges.

  Environmental Interaction: Use steam vents for mobility and concealment.

  Advisory: Do not allow multiple bites to stack. Prolonged exposure may cause burns and tissue damage to unprotected targets.

  “Ah,” James said. “Appetizers.”

  Gerrard lifted his hands in horror. “Why are they looking at me like I am a buffet?”

  “You are sweating the most,” Mira whispered.

  “Then everyone else start sweating more,” he hissed.

  One of the lizards snapped forward, so fast it blurred. Vhara stepped into its path, sword sweeping down. The flat struck the stone just in front of the creature, redirecting its momentum. It skidded sideways with a furious hiss.

  The pack reacted as one.

  They surged.

  Vhara moved first. She planted herself between the lizards and the squishiest members of the group, shield coming up in a smooth motion. Steam bursts smacked against the metal, leaving faint, hissing trails. Her sword darted in short, efficient arcs, keeping the closest fangs away from the others.

  James slipped to her flank, Nyinwym already in his hand, Combat Sense tightening his perception until motion and intent aligned. The heat of the vents mixed with the rhythm of his pulse, the whole world narrowing into timing and angles.

  “I will use a containment ring,” she called. “Force and earth, slow them and break the circle.”

  Mira raised her staff. Light gathered at the gems along its head as the system interface flickered briefly across her vision.

  [Skill Activated: Containment Ring]

  Gerrard crouched behind Vhara and did his best impression of a very brave stone. “If anyone needs me, I will be here reconsidering every career choice I have ever made.”

  A lizard shot toward him, claws clacking on stone.

  James intercepted.

  [Knife Precision Activated]

  He shifted grips mid-motion, blade flashing out only for the strike itself as Combat Sense guided the angle. The lizard’s jaw opened, revealing that faint glow again.

  Back of the jaw, he thought. Where the bone hinges.

  The blade slid in just behind the angle of the jaw, where the skull met the spine. Resistance gave way like cartilage between ribs. The lizard’s body went limp in an instant, momentum carrying it harmlessly into James’s shin.

  He stepped aside and let it fall, already turning to face the next.

  “One point of articulation,” he said. “Very forgiving design.”

  “Less commentary, more not dying,” Gerrard yelped.

  Two lizards darted at Vhara’s shield, jaws clamping onto the rim. Steam hissed where their teeth scraped the metal, leaving faint scorch lines. She grunted, muscles bunching, and slammed the shield sideways into the wall. The lizards crunched between metal and stone, sliding down in a dazed tangle.

  The Containment Ring finished forming.

  A wave of force rippled out, the mana catching dust and loose stone. A circular ridge of rock surged up around the party, knee high, then waist high as the mana-dense environment amplified the effect beyond Mira’s intent.

  “Too much,” she gasped.

  The ridge overshot her intention, slamming into the side wall with a resounding crack as the Heatstone resisted the sudden surge of mana. Heatstone fractured, sending a shower of red shards across the tunnel. A hairline split raced up the wall and across the ceiling.

  For one terrifying second, everything groaned.

  Then the wall held.

  Unfortunately, the burst had also kicked several lizards into the air.

  They arced in slow, angry trajectories straight toward the group.

  Mira winced. “Sorry. The mana here amplifies everything.”

  “Mira,” James said. “Later. Duck now.”

  She dropped. A lizard sailed over her head, steam bursting from the vents along its back as it tried to correct. James moved through the gap, blade flashing.

  [Butchery Activated]

  He carved a neat line along the belly of one as it passed, just deep enough to sever vital threads without spilling everything. The lizard hit the ground, twitched, and stilled.

  Another went for his arm.

  It clamped down.

  The initial heat dispersed harmlessly as Mana Shield flared, absorbing the worst of it before fading again. James hissed more in irritation than pain and twisted, catching it by the tail.

  He swung it in a quick arc and slammed it into the stone beside another, stunning both.

  “Apologies,” he muttered. “You started it.”

  Vhara held the line, shield a solid wall that clanged each time jaws hit. Her sword took on a rhythm, short cuts aimed at joints. She pinned one lizard through a back leg, then twisted, using its body to knock another away.

  Gerrard made the mistake of peeking over the shield.

  One of the lizards locked eyes with him. Its pupils narrowed. It spat a small jet of superheated steam.

  Gerrard yelped, dropping back just in time. A thin shimmer of force flared instinctively in front of him, deflecting most of it so the remaining steam splashed against the ridge behind and left a blackened patch.

  “Very well,” he squeaked. “I will simply not exist.”

  Another lizard scuttled along the ridge, seeking a way around. Vhara took it off the stone with a sharp shield bash, sending it spinning into the air. Steam flared from its back vents as it tried to correct. James stepped in and finished it with a precise cut to the neck.

  The pack began to thin.

  The surviving lizards slowed, tongues flicking. They backed toward the vents, bodies low.

  “They are reconsidering,” Vhara said.

  “Good,” Gerrard panted.

  “Do not give them time to decide otherwise,” she added.

  James lunged for one that was trying to retreat. It hissed and snapped backward, jaws clamping on his boot. Heat washed over the leather but failed to bite through.

  Mana Shield flickered again, dispersing the thermal spike before it could take hold.

  He bent quickly. The angle was awkward, but the anatomy was the same. He slid the blade in behind the jaw, twisting just enough. The lizard’s grip slackened. He shook his foot free, boot steaming faintly but intact.

  “Note,” he muttered. “Do not let them nibble.”

  “One escaped,” Mira warned.

  Sure enough, a single lizard had made it to a vent. It paused, eyes glittering, then launched itself down into the steam, vanishing into the red dark.

  Vhara lowered her shield slightly. “Let it carry news,” she said. “We are not easy prey.”

  Gerrard sagged against the ridge. “I would prefer the news to be that we are not here at all.”

  James exhaled slowly.

  The tunnel smelled of hot stone, reptile musk, and mineral-laced steam. His heart thudded in his chest with the same relentless pace as a busy night on the line. He looked at the scattered bodies, at the scorch marks, at the thin cracks in the wall where Mira’s spell had overreached.

  “Everyone intact?” he asked.

  Mira nodded, cheeks flushed. “I am fine. The control slipped, I am sorry.”

  Vhara shook her head. “Messy but effective. Adjust your control, not your courage.”

  Gerrard lifted one hand weakly. “My soul has left my body but the rest appears to remain present.”

  “You will live,” James said. “And now we have data.”

  They had bought themselves a brief window, nothing more.

  He crouched beside one of the bodies.

  James’s smile tugged at one corner. “Spicy, earthy, and already half steamed. Efficient.”

  He paused, eyes still on the floating text. “And regret. Cute.”

  Mira leaned over his shoulder. “Regret as a flavor profile,” she said dryly. “Fitting.”

  Gerrard peered down from a safer distance. “You are not about to suggest we eat the things that tried to eat us.”

  “Of course I am,” James said. “We fought hard for this protein.”
