My AI Wife: The Most Beautiful Chatbot in Another World-Chapter 51: The Stone Breath

The light within The Glowing Hearth did not change with the rising of a sun, for there was no sun in the hollowed-out womb of the earth. Instead, the gargantuan turquoise crystals embedded in the cavern’s vaulted ceiling—the bioluminescent heart of the mountain—underwent a rhythmic chromatic shift. The dim, oceanic blue that signaled the cycle of rest slowly pulsed, warming into a rich, flickering amber-orange. This transition was accompanied by the deep, resonant tolling of the Great Anvil Bell, a sound that vibrated through the bedrock itself, signaling a new day. In Terragard, time was not measured by the rotation of a planet, but by the "Stone Breath"—the geothermal heartbeat of the mountain, regulated with obsessive care by the Dwarven artisans.

Dayat stirred, consciousness returning to him in waves. He felt a heavy, comforting warmth draped over his left arm. He didn’t need to look to know who it was. Dola was there, her eyes closed in a simulated slumber, her head resting trustingly on his shoulder. Her breathing was steady, a perfect imitation of a human’s nocturnal rhythm. Looking at her now—her porcelain skin unblemished and her silver hair spilling like a frozen river across the white furs—no one would guess that this girl was a bio-synthetic war engine capable of erasing a battalion from the face of the earth.

Dola’s eyelids fluttered. Her electric-blue pupils flared with a brief surge of light before dimming into a softer, more intimate shade of sapphire.

"Good morning, Dayat," she whispered.

The mechanical distortion that once haunted her voice was gone, replaced by a soft, melodic warmth that she reserved solely for the man beside her. "Room temperature: 26 degrees Celsius. Humidity: 40%. My internal system has successfully synchronized with the city’s geothermal frequency during your period of unconsciousness."

Dayat offered a small, sleepy smile, his hand reaching out to gently stroke her hair. "Morning, Dol. Sleep well? Or... hibernating well?"

"Unit Alpha does not require ’sleep’ in the biological sense, however, the hibernation mode initiated in your proximity has increased my emotional processing efficiency by 14.8%," Dola replied. She sat up with a fluid grace, smoothing out her new navy tactical jacket. The moment she stood, her posture shifted—shoulders back, chin up, eyes sharp. She was back in protector mode, elegant yet lethal.

In the corner of the room, Kancil was still a sprawled mess on the sheepskin rug, his snores rhythmic and loud enough to rattle the washbasin. Lunethra, however, was already a pillar of activity. She sat by a stone-carved window that overlooked the vertical chasm of the underground city, methodically polishing her silver daggers. Her expression was unreadable, her emerald eyes reflecting the glowing magma conduits in the distance.

"We do not have the luxury of laziness," Lunethra said without turning her head. "The Dwarves are a race born of stone and industry. To wake after the third bell is to be branded a parasite on society. In Terragard, survival is a meritocracy."

Thud! Thud! Thud!

The heavy iron-oak door nearly jumped off its hinges as someone hammered from the outside.

"Open up! It’s Captain Grimbar! I’ve brought someone who is itching to taste the ’technology’ you’ve carried into my mountain!"

Dayat sighed, rolling out of the furs and tugging on his boots. He checked his reflection in a polished copper mirror—he looked haggard, but his eyes were clear. "Come in, Captain. The door isn’t locked."

The door groaned open, revealing the burly, armored frame of Grimbar. His four-braided beard looked freshly polished, each gold ring gleaming. But it was the figure beside him that drew Dayat’s attention. The newcomer was nearly a head shorter than Grimbar, dressed in robes of heavy black velvet adorned with a sash overflowing with gold and silver medals. He wore a pair of thick, double-lensed brass bifocals that made his eyes look like those of a giant insect.

"This is Borkum Steel-Eye," Grimbar introduced, his tone carrying a hint of bored exhaustion. "Minister of Traditional Innovation. He’s the one who decides what is ’progress’ and what is ’garbage’ within the walls of Karak-Zorn."

Borkum stepped forward, his nose twitching as if he smelled something rotting. He tilted his head back, aiming his magnified gaze first at Dayat, then at Dola. His stare was cold, weighted with the deep-seated prejudice of a master craftsman looking at an amateur.

"So, this is the human who babbles about ’frictional precision’?" Borkum’s voice was high-pitched but carried a jagged edge of authority. "And what is that... that thing outside? That steam-carriage? It is a piece of Brassvale pollution. In Terragard, we harness the pure, silent heat of the earth. We do not choke our lungs with the black soot of a primitive boiler."

Dola took a single, sharp step forward, positioning herself like a shield in front of Dayat. Her gaze turned to ice. "My name is Dola Nur Mustafidl. The unit you refer to as ’pollution’ is the singular variable that allowed us to cross The Wailing Woods alive. Your critique lacks objective data and fails to account for the environmental constraints of the Lowlands."

Borkum recoiled, his face turning a shade of brick-red. He was not used to being corrected by a woman, let alone a human ’ascent.’ "How dare you! Grimbar, you said they were refugees, but this woman speaks as if she is a Queen of a High Throne!"

"She’s my wife, Minister," Dayat interjected, his voice firm and resonant, silencing the Dwarf’s protest. "And she is correct. we are not here to insult your achievements. We are here to seek asylum and passage to Verdia. We bring knowledge that can bridge the gap between your traditions and the future."

Borkum snorted, adjusting his bifocals with a click of metal. "Asylum is a currency earned, not a gift given. We are a people of Merit. If you are just another soft-skinned human who cannot even forge a proper nail, then you are nothing but an extra mouth to feed. Follow me to the Hall. Let us see if your mind is as sharp as your wife’s tongue."

The Descent into Karak-Zorn

They left the inn and stepped out onto a massive stone balcony that jutted over the heart of Karak-Zorn. Dayat stopped, his breath catching in his throat. Before him lay a subterranean cavity so vast it had its own weather system. Clouds of white steam gathered near the distant ceiling, hundreds of meters above. Thousands of stone bridges, as delicate as spiderwebs, crisscrossed the air between gargantuan stalactites, connecting floating workshop-districts that echoed with the rhythmic, metallic thunder of ten thousand hammers.

In the center of the chasm stood the Pillar of Fire—a massive, transparent tube of heat-resistant crystal filled with flowing magma. It acted as a glowing orange spine for the city, distributing energy to the heat-exchangers that powered every forge in the mountain.

"Wah... gila... this is incredible," Kancil muttered, having finally woken up. He followed behind with wide eyes, his hands twitching nervously. The heights of Terragard were far more intimidating than the rooftops of Bakasa.

Dayat noticed Kancil’s anxiety. He reached into his jacket pocket, appearing to fumble for something while he focused his mental energy. He visualized the tactile click of plastic, the monochrome LCD screen, and the simple 8-bit circuitry of the 1990s.

[MANIFESTATION: GAMEBOT – BRICK GAME 9999 IN 1.]

A bright yellow plastic device appeared in Dayat’s hand. He handed it to Kancil without a word.

"Here, Kancil. Take this. It’ll stop you from obsessing over the abyss. It’s called a Gamebot. Press these buttons to arrange the falling blocks. Don’t let the screen fill up."

Kancil took the alien object, confused. But as the monochrome screen flickered to life and the iconic bip-bip-bip melody echoed in the quiet of the balcony, the boy’s eyes lit up. "Is this... magic, Bang?"

"No. It’s entertainment logic," Dayat replied, glancing at Borkum. The Minister was staring at the yellow device with a look of profound suspicion. He clearly wanted to ask what it was, but his Dwarven pride kept his mouth shut.

They reached a massive elevator platform made of high-grade stainless steel. Grimbar pulled a heavy steam-lever, and the platform began to slide down into the deeper levels of the mountain with a cacophony of grinding gears and hissing valves.

"Listen to me, Human," Borkum started again, his voice trying to compete with the roar of the elevator. "Grimbar tells me you gave him a ’ball bearing’ with a tolerance that defies the eye. I do not believe it. I think you are nothing more than a low-level Transmutation Mage from Brassvale, trying to trick us with shape-shifting illusions. Metal has a soul, boy. It must be tempered in fire, not changed with a chant."

Dayat leaned his back against the elevator railing, looking unbothered. "Minister Borkum, transmutation magic only changes the nature of what already exists. Turning iron to gold, or air to water. But that’s not what I do. I don’t change the metal. I define it."

"Then what do you call it?" Borkum challenged, his hand gesturing wildly.

Dayat glanced at the elevator lever Grimbar was holding. Near the base of the mechanism, a large bolt was visibly vibrating, causing an excess of noise and a slight shudder in the platform’s descent. Dayat closed his eyes for a second.

[MANIFESTATION: DIGITAL CALIPER – STAINLESS STEEL. LINEAR ENCODER SENSOR. LCD READOUT.]

Without a flash of light or a surge of Mana, a modern, high-precision measuring tool suddenly sat in Dayat’s hand. He stepped toward the lever and clamped the jaws of the caliper around the vibrating bolt.

The small digital screen flickered to life, displaying a number: 32.45 mm.

"This bolt was designed for a 32.00 mm housing, Minister," Dayat said casually, turning the screen so Borkum could see the glowing digits. "This inefficiency of 0.45 mm is the reason this elevator vibrates. Within three months, this oscillation will cause a fatigue fracture in the primary bearing. I didn’t use magic to see that. I used precision. I don’t need to change the metal’s soul when I can calculate its reality."

Borkum froze. He snatched the tool from Dayat’s hand, his fingers trembling. He had never seen a device that could produce numbers automatically. He rubbed his thumb over the steel, searching for a trace of Mana residue, a hidden rune, or a spectral thread. He found nothing. The object was cold, physical, and terrifyingly accurate.

This thing... it has no Mana signature. How is it possible to know the truth of metal without magic? Borkum thought, his hostility beginning to erode under a wave of overwhelming curiosity.

The elevator came to a halt at the mid-level, known as The Great Workshop District. As the gates slid open, the scent of sulfur and white-hot iron hammered their senses. Lunethra stepped out first, but she paused for a moment, glancing back at Dayat with a look that had shifted from amusement to wariness.

"You love to show off, Dayat," Lunethra whispered, her voice low enough that only he could hear. "But be careful. Your talent for pulling things out of the void is a gift that will make the Gods envious and the Demons hungry. Do not reveal all your teeth at once."

Dola, whose auditory sensors were far superior to any human’s, immediately stepped closer. She wrapped her arm possessively around Dayat’s, her sharp gaze fixed on the Elf.

"Dayat is merely demonstrating technical facts, Lunethra," Dola replied coldly. "In this world, the truth is often mistaken for arrogance by those who lack the capacity to reach it."

Lunethra simply shrugged, a faint, knowing smile playing on her lips. She seemed to enjoy the possessive reactions of the "Assistant."

Grimbar led them through a gauntlet of Dwarven blacksmiths, each one pausing their hammer-strikes to stare at the strange group passing through their sanctum. At the end of the main thoroughfare stood a gargantuan dome-shaped building with a chimney made of pure crystal.

"That is the Hall of Innovation," Grimbar said. "Master Ironbeard is waiting. But be warned, Dayat. Inside those walls, it won’t just be Borkum testing you. The entire Council of Ministers will be watching to see if you are truly an ’Innovator’... or just another piece of wreckage swept in by the wind from the East."

Dayat took a deep, steadying breath, feeling the searing heat of Terragard fill his lungs. He looked at Dola, who gave him a firm, supportive nod. Beside him, Kancil was still engrossed in his Gamebot, completely oblivious to the weight of the moment.

The battle for Terragard had begun. And for the first time, it wouldn’t be fought with guns, but with the cold, hard logic of the machine.
