My AI Wife: The Most Beautiful Chatbot in Another World-Chapter 65: The Fortress Hold

The darkness within The Deep Steam Vents was no longer a mere absence of photons; it was a heavy, viscous gloom that felt as if the air itself had acquired a physical mass, pressing against the lungs and slowing every heartbeat. Far below, at the jagged bottom of the artificial abyss that bifurcated this industrial sector, the magma flows of Terragard emitted a dull, rhythmic crimson radiance. This hellish light reflected off the rough basalt walls, casting long, distorted shadows that seemed to dance with malevolent intent. The scalding steam erupting from ruptured gargantuan pipes created an eternal, suffocating fog, turning visibility into a luxury that Dayat could no longer afford.

Dayat stepped onto the rusted metal grating of the lower platform after disembarking from the manual pulley system. His legs buckled instantly. Every muscle fiber in his lower body vibrated with a violent tremor, and his vision began to fracture—black spots swirled at the periphery of his sight, a physiological siren warning him that his Mana reserves had touched the absolute critical threshold.

"Master, your neural synchronization is displaying early signs of cognitive degradation due to extreme Aetheric depletion," Dola’s voice echoed within his mind. This time, however, her tone possessed a microscopic shift—a hint of something softer, perhaps even protective, though it remained draped in her characteristic efficiency.

Dayat forced himself to stand upright, using his HK416 as a makeshift crutch against a massive stone pillar. "I’m not... I’m not going down yet, Dola. Just need a moment. We need a fallback point. We can’t keep running in this maze."

Before them stood a monumental relic of Dwarven engineering: The Great Vault Door. Forged from a high-density composite of adamantite and reinforced steel, it remained sealed, its complex locking mechanism requiring a sequence of steam-pressure resets to activate. They were currently trapped in a wide, dead-end corridor; the only entrance was the long, narrow tunnel they had just traversed.

"Kancil, help me move those debris," Dayat rasped, his throat feeling like he had swallowed hot coal.

Kancil, who despite being covered in soot and scratches appeared the most resilient of the group, moved with a thief’s agility. He began stacking metallic wreckage and discarded ore-bins at the mouth of the corridor, creating a rudimentary obstacle course for anything trying to rush them.

Suddenly, a soft, pained groan drifted through the steam. Lunethra, who had been lying limp after Dola’s decidedly unceremonious transport, began to stir. The ancient Elf gasped, trying to scramble to her feet, only to collapse back onto the cold stone as her circulation slowly returned to her numbed limbs.

"Where... where are we?" Lunethra whispered, her silver eyes widening as she took in the scene.

Dayat stood in the center of the hall, his arms extended. A brilliant, sapphire-blue light of manifestation erupted from his palms, greedily devouring the ambient Mana from the stagnant air. In the heart of the gloom, particles of light began to solidify into a complex, interlocking structure.

First, the Hesco Barriers materialized—gargantuan wire-mesh baskets that instantly filled themselves with compacted earth and gravel, forming chest-high fortifications in a matter of seconds. Dayat arranged the barricades to choke most of the corridor’s width, leaving only a narrow, zig-zagging gap for tactical navigation.

"What kind of... sorcery is this?" Lunethra asked, her voice trembling with awe.

"Good morning, Elven Unit," Dola replied, standing guard beside Dayat. "You are witnessing the pinnacle of Earth’s engineering logic. My Husband does not weave spells; he manifests mechanical realities that bypass the primitive logic of your world."

Lunethra stared at Dola, then back at Dayat, who was now hunched over in visible agony. "He... he is using his very life force to pull these anomalies from the void?"

"Save the commentary, Lun," Dayat interrupted, wiping cold sweat from the nape of his neck. "Dola, initialize the Sentry routine. We need a path-clearer."

Dayat squeezed his eyes shut, reaching into the scorched-in military data Dola had previously synced to his cortex. A small, violent explosion of blue light flared atop a heavy-duty steel tripod. A terrifying device appeared: the M134 Minigun Sentry. Six long, blackened steel barrels, a high-capacity ammunition belt containing thousands of shimmering 7.62x51mm NATO rounds, and an optical sensor array linked directly to Dola’s combat sub-routines.

Before activating the beast, Dayat manifested three pairs of matte-black Electronic Ear-Muffs. "Put these on now! Kancil, Lunethra, do it! Dola doesn’t need them, but you do unless you want to spend the rest of your lives in absolute silence."

As soon as their hearing protection was secured, a low, thunderous rumble began to echo from the far end of the tunnel. It was the sound of thousands of obsidian claws hammering against metal. The shrieks of a starving Dretch swarm vibrated through the stone, creating a physical wave of terror.

"They’re here," Kancil muttered, gripping his Vibro-knife in one hand and the Glock 17 in the other. He crouched behind the Hesco barrier, his eyes fixed on the kill-zone.

Dola stepped forward, her hand brushing the rear housing of the Minigun. Her eyes flared with an intense, electric-blue radiance as she slaved her consciousness to the weapon’s automated targeting system. In this world, Dola possessed a control capability akin to a high-level vision-sharing technique; what the Sentry’s sensors saw, Dola processed instantly.

"Activating Perimeter Defense Protocol," Dola stated coldly.

VRRRROOOOOOMMMM...

The six barrels began to rotate with a high-pitched, intimidating electric whine as the motor spun up to speed.

"Wait, Dayat! Those demons have hides reinforced by Abyssal Mana! Ordinary iron will not—" Lunethra’s warning was cut short.

BRRRRRRRRRRRTTTTTTTTTTTT!!!!

The entire dead-end corridor exploded in a continuous, blinding sheet of muzzle flash. A cyclic rate of 3,000 rounds per minute created an unbroken line of orange fire. The sound was no longer that of individual gunshots; it was the sound of a gargantuan mechanical saw cutting through the very fabric of the world.

The vanguard of the Dretch swarm vanished instantly. The copper-jacketed lead, traveling at supersonic velocities, didn’t just pierce their hides—it shredded their physical forms into a fine mist of black ichor and smoking ash in a heartbeat. There were no spells, no counter-chants; only pure kinetic energy obliterating biological matter with industrial efficiency.

"S-so fast..." Kancil was paralyzed by the spectacle. The demons that had seemed like invincible nightmares were now nothing more than piles of smoldering soot being swept away by the thermal wind of the barrels.

Dola stood rigid amidst a rain of hot brass casings that clattered onto the metal floor in a rhythmic, metallic dance. She navigated the Minigun with terrifying precision, sweeping from left to right, ensuring that no shadow remained unpunished.

However, in the heart of the mechanical slaughter, Dola’s head tilted at an odd angle. A flicker of static glitch appeared in her sapphire eyes.

(Hehe... just crush them all... erase the filth...)

A cold, feminine laugh—distorted and ancient—whispered within Dola’s internal processors. It was the voice of The Maiden. Dola flinched, her reaction time lagging by a mere 0.5 seconds—a window that allowed a cluster of winged Imps to spiral over the primary fire-zone.

"Dola! Focus!" Dayat screamed, seeing the Imps diving toward them.

"Eliminating internal interference. Resuming primary directive," Dola snapped, her eyes returning to normal. She pivoted the barrels upward, disintegrating the Imps before they could release their entropic fireballs.

Amidst the chaos, Dola glanced at Lunethra, who was staring at Dayat with a mixture of terror and reverence. Whether driven by the Maiden’s glitch or her own evolving core, Dola spoke loudly enough to be heard over the mechanical roar.

"Elven Unit, do not direct your visual focus toward my Husband for excessive durations. For your database’s records: I hold the status of ’Legally Administrative Wife’ within Dayat’s emotional architecture. Your function here is that of a temporary logistical burden. Do not harbor expectations of a higher tier."

Lunethra blinked, her jaw dropping. In the middle of a demonic siege and a hail of bullets, she had just been territorially marked by a mechanical assistant. "W-Wife?"

Dayat heard none of this, his focus fractured by the encroaching Mana Collapse. His vision was tunneling. He felt as if he were floating, his eyes opening and closing in a desperate attempt to process the radar data Dola was streaming to his HUD.

"Dwarves... they’re close," Dayat muttered. Through the vibrations in the floor, he could feel the rhythmic, heavy tread of elite Earth-Shielders approaching their position from behind the Vault Door. The Dwarves had secured the upper sectors and were now moving to seal the final breach.

But before reinforcements could arrive, the atmosphere at the tunnel’s end shifted violently.

The sound of the Minigun’s impact suddenly turned dull, as if hitting solid stone. Dola ceased fire, the barrels slowing to a halt. The ambient heat from the steam pipes seemed to be sucked toward a single point in the darkness.

A gargantuan silhouette emerged. It stood nearly three meters tall, a mass of explosive musculature covered in obsidian-black skin that looked like tectonic basalt plates. Its eyes weren’t red like the common Dretches; they were a deep, bruised purple that radiated a localized gravitational pressure.

The Dretch Alpha.

The demon let out a low, guttural growl that vibrated in Dayat’s very marrow. It raised an arm the size of a tree trunk, casually parrying the remaining stray rounds with a forearm coated in dark-mana crystals. The bullets ricocheted harmlessly, leaving nothing but minor scratches on its stony hide.

"Target identified: Unit Dretch Alpha. Standard 7.62mm ball ammunition displays a penetration effectiveness of only 12.4%," Dola reported, her voice returning to its chilling, serious register.

"Shit... lead isn’t enough," Dayat tried to stand straight, his hands shaking violently as he attempted to reach into his soul for one last manifestation. "Dola... we need something heavier... something with more mass... or we’re going to be turned into paste."

Behind them, the gears of The Great Vault Door began to groan and rotate. The sound of Dwarven machinery signaled help was seconds away, but the Dretch Alpha had already begun its charge, its massive frame moving with a speed that defied the laws of inertia.

"Kancil! Lunethra! Get behind the gate seals!" Dayat roared, leveling his HK416 for a final, desperate stand, even though he knew he was firing pebbles at a tank.

Their impregnable fortress was about to be tested by the true, unadulterated strength of the Abyss.
