Chapter 96 Pressure Burns

The subterranean corridor trembled with continuous high-frequency vibrations as superheated steam hissed from fractured pipe flanges. Dense clouds of white vapor rolled along the ceiling of sub-level three, obscuring the flickering lantern brackets that lined the railway tunnel.

Ren stepped over a burst pressure line, his reinforced footwear splashing through pools of scalding mineral condensate that pooled across the broken stone tiles.

He paused beside a cluster of dead cave vermin lying in the drainage gutter, kneeling to inspect their ruptured flesh with sharp analytical focus.

"These cave runners have identical internal barotrauma to the river fish we found in the southern wetlands..." Ren observed in a grim whisper, turning a carcass over with the tip of his sheath. "Their swim bladders and lung sacs ruptured from sudden hydrostatic shockwaves rather than thermal burns!"

Akane knelt beside him, holding a portable brass pressure tester against the exposed rock fissure to record the seismic oscillation frequency.

"The acoustic pressure frequency matches the seismic pulses we recorded during the flooded shaft investigation..." Akane reported, her brow furrowing with deep technical concern. "The Firecrest Salamander had no natural capability to generate synchronized compression waves of this magnitude!"

Ren stood up from the wet stones, looking down the corridor toward the rumbling compressor station where the massive steam manifolds were vibrating under immense load.

"The salamander was merely a territorial scavenger feeding on the volcanic runoff..." Ren deduced, his unmasked senses analyzing the steady tremors. "The true source of these catastrophic pressure pulses is an immense biological organ pumping deep within the mountain's mantle."

Akane checked the thermal gauge on her wrist bracket, noting that the ambient temperature was climbing by three degrees every two minutes.

"If that deep biological core surges again while the pressure relief lines are locked..." Akane explained, adjusting the brass focus ring of her gauge. "The expanding steam will blow the main bedrock floor right into the residential quarters above!"

A terrified young apprentice mechanic scrambled down the railway line from the extraction junction, his shirt soaked with sweat and black machine grease.

"Foreman Gendo locked the emergency release valves in the compressor room!" the young worker gasped, clutching Ren's sleeve with trembling hands. "He told the afternoon shift that your clearance contract proved the lower shafts were completely safe, and forced forty men back onto the drilling platforms!"

Akane's eyes flashed with furious indignation, her fists clenching around her magnetic wrench as she stepped between the apprentice and the rattling pipes.

"That monster is using our hard-won victory as a legal pretext to force those men into a lethal blast zone!" Akane shouted, her voice echoing off the damp masonry. "If the main compressor manifold blows under this pressure load, the entire third level will collapse in seconds!"

Ren tapped his belt pouch, confirming his six bound masks remained fully primed and ready for rapid combat deployment across the subterranean complex.

The system interface provided a flawless display of his physical attributes and elemental affinities, yet no magical prompt could untangle the web of corporate greed and forged administrative ledgers.

Survival on the frontier demanded cold human discernment, technical precision, and the courage to confront ruthless men who valued mineral profits over human lives.

"We do not need a magical appraisal prompt to recognize an illegal corporate operation," Ren said calmly, resting his hand upon his sword hilt. "We are going to breach that compressor station, shut down the rogue drills, and extract every worker from the hazard perimeter."

The young apprentice pointed toward a reinforced steel doorway thirty paces ahead, where thick electrical conduits converged into a central junction box.

"The main control room is behind that blast door..." the apprentice explained, handing Akane a copper maintenance key. "Gendo stationed four armed corporate enforcers at the threshold with orders to shoot anyone who attempts to touch the emergency breaker!"

Akane took the key, inspecting the security warding with a sharp, calculating glint in her eyes as she checked the charge on her magnetic flux cutters.

"Four corporate mercenaries cannot stop a master armorer with high-frequency magnetic shears and a C-rank hunter with six masks!" Akane declared with fierce resolve. "I will disable the magnetic door locks from the external junction box while you neutralize the guards!"

Ren reached into his leather coat, verifying that his personal cash reserve remained steady at two hundred twenty-two silver pieces.

[ Personal Cash: 222 Silver | Bounty Verification Pending ]

The four hundred silver bounty remained officially frozen because the station staff refused to stamp the clearance certificate, but financial rewards meant nothing while innocent workers were trapped in the line of fire.

The apprentice mechanic pulled a folded schematic from his leather vest, tracing the emergency ventilation route that bypassed the fortified checkpoint.

"The overhead exhaust flue connects directly to the crane gallery above the primary steam turbines..." the young worker added in an eager whisper. "If you drop in from above, the guards will have no time to bring their heavy crossbows to bear against your shield!"

"Your structural knowledge has given us the exact tactical breach we need," Ren replied, memorizing the dimensions of the overhead duct. "Stay behind this reinforced masonry bulkhead until we clear the room and signal the all-clear!"

Shizuka stepped out from the shadow of the ventilation shaft, her short courier blade drawn and ready in her right hand.

"I intercepted an internal company dispatch that Gendo sent toward the capital garrison half an hour ago..." Shizuka reported in a low, sharp whisper. "He ordered his private mercenaries to execute an immediate scorched-earth evacuation if any inspectors enter the main quarry gate!"

Ren acknowledged her crucial intelligence report with a firm nod, recognizing that the corrupt foreman was preparing to destroy all physical records of his illegal mining quota.

"That confirms Gendo knows the geological fault line is failing and intends to leave no living witnesses behind," Ren said, checking the quick-release buckles of his shield harness. "We move simultaneously—Shizuka secures the dispatch registry while Akane and I breach the compressor room!"

They moved along the corridor in coordinated silence, keeping their silhouettes low against the billowing steam banks that rolled across the floor.

Ren touched his fingers to the floor, activating his seismic vibration sense to map the positions of the guards behind the portal.

[ Equipped mask: Glassfoot Spider | Source rank: E ]

[ Personal rank: C | Agility: 56 | Perception: 55 | Seismic Vibration Sense Active ]

Two guards stood on the immediate threshold with loaded crossbows, while two more patrolled the elevated catwalk above the compressor cylinders.

Behind the security detachment, thirty exhausted miners were frantically shoveling glowing volcanic crystal into mechanized conveyor hoppers, completely unaware that the primary steam manifold was vibrating on the verge of explosive structural failure.

Shizuka drew a mechanical security stylus from her pouch, passing the specialized tool to Akane with a sharp, decisive nod.

"This bypass stylus matches the administrative cipher that the chief engineer used before Gendo took over the sector..." Shizuka explained in a rapid whisper. "If you insert it into the secondary diagnostic port, it will override the emergency lockdown and prevent the bulkhead doors from sealing shut!"

Akane examined the gold-plated pins on the stylus, her eyes flashing with renewed confidence as she aligned it with the terminal.

"This cipher will shave four seconds off our door breach and keep the evacuation corridors open for the miners!" Akane declared with quiet triumph. "Every piece of the puzzle is falling into place!"

Ren adjusted his grip on his hooked blade, channeling his unmasked core strength through his shoulders as the steam surged around them.

"The guards are positioned in a standard crossfire formation behind the blast door..." Ren whispered to Akane, gesturing toward the overhead ventilation grate. "I will drop through the ceiling baffle using Night Moth wings to disarm the upper snipers, while you breach the main portal."

Akane nodded firmly, attaching her magnetic bypass clamps to the copper terminals of the external junction box with steady hands.

"Bypass circuits are live and charging across the primary relay..." Akane whispered back, her fingers steady on the magnetic dial. "The locking bolts will retract in exactly five seconds on your mark!"

Before Ren could give the operational signal, the shrill wail of an automated evacuation siren shrieked through the subterranean shafts.

A harsh mechanical voice blared from the station loudspeakers, announcing the immediate closure of all secondary safety doors across sub-levels three and four. Through the floor grates, the distant sound of panicked shouting echoed from the lower gate, where Yui was still treating wounded workers on the medical platform.

Gendo initiated an emergency lockdown, intending to seal the lower tunnels and trap the miners behind reinforced bulkheads while his private security detachment evacuated the valuable crystal crates.

"The coward is sealing the exits to cover his tracks and trap the evidence!" Akane gasped, throwing her full mana into the magnetic bypass. "Ren, breach the control room right now!"

Ren leaped toward the overhead ventilation shaft, channeling the spectral wings of his Night Moth mask as he shattered the iron grate with a single upward kick.

The stage was set for an uncompromising assault against the corporate masters of Mount Kurotake, where steel, honor, and human life hung in the balance.

With unyielding focus and steady breath, the hunters moved as one to shatter the corporate blockade and save the workers of Suzuhara.
