The walk to Orario was a sensory overload that no amount of 4K resolution or high-fidelity anime could have prepared Nyt for. As a man who had spent the better part of his life staring at whiteboards and flickering monitors, the sheer vibrancy of the world was an assault on his retinas. The air didn't just feel clean; it felt heavy, saturated with a sparkling, invisible pressure that Minerva identified as ambient mana.

  "Administrator," Minerva’s voice chirped in his mind, her tone as precise as a Swiss watch despite the 98% data corruption she had suffered. "Local atmospheric pressure is consistent with Earth’s sea level, but the oxygen-to-nitrogen ratio is slightly optimized for cardiovascular endurance. I am currently adjusting your metabolic rate to prevent 'mana-sickness' from the high-density environment."

  "Don't just help me to adopt, Minerva," Nyt whispered, his eyes wide as he crested a final hill. "Record everything. Every photon, every blade of grass. This isn't a simulation. It’s a violation of every thermodynamic law I’ve ever published."

  Before him sat Orario, the Labyrinth City. From this distance, the city walls looked like the rim of a gargantuan bowl, and at its center, the Tower of Babel stood like a middle finger to the square-cube law. It was an architectural impossibility—a structure so massive that its own weight should have caused it to sink into the tectonic plates.

  "The compressive strength of that stone must be astronomical," Nyt muttered, his fingers twitching as if he were already typing a thesis. "Or... it’s reinforced by a constant localized gravitational field. It’s a miracle of physics, Minerva."

  [Hypothesis: Divine Intervention.] Minerva replied. “My sensors detect a fundamental 'authority' radiating from the tower. It is not just a building; it is a seal.”

  As Nyt joined the long, winding queue at the Northwest Gate, his excitement began to override his exhaustion. He was a man of logic, but he was also an enthusiast. Seeing a line of Ganesha Familia guards in their ornate elephant-themed armor was one thing but seeing the people was another.

  He was surrounded. To his left, a group of Pallum's small, hobbit-like beings were laughing over a map of the upper floors. To his right, a tall, regal Elf with hair the color of spun moonlight stood with a posture that would have made a ballerina look like a slouch. There were Beastmen with twitching ears, cat-folk, dog-folk, and even a hulking Ox-man carrying crates that would have required a forklift in his previous world.

  "Incredible," Nyt breathed, his gaze darting from one demi-human to the next. "The genetic divergence here is staggering. Minerva, scan the muscle-to-bone density of that Werewolf over there."

  [Scan Complete. Estimated physical output: 4.5 times that of an average human male of the same mass. Note: The 'Falna' on his back is acting as a biological capacitor, augmenting his musculoskeletal system.]

  "A biological capacitor," Nyt repeated, a manic grin forming. "It’s not magic. It’s an upgrade. It’s the ultimate hardware patch."

  When Nyt finally reached the front of the line, the guard looked him up and down. Nyt was a strange sight: he still wore his tattered, singed lab coat, his shirt was missing buttons, and his cracked glasses were held together by a prayer.

  "Name and business," the guard grunted.

  Stolen from its original source, this story is not meant to be on Amazon; report any sightings.

  "Nyt," he replied, his voice brimming with a confidence that came from knowing exactly how the universe worked even if this universe had a few extra rules. "I’m here to seek an audience with the Hephaestus Familia."

  The guard chuckled, stamping a parchment. "Another one for the forge, eh? Follow the North Main Street until you smell the sulfur and hear the hammers. If you’ve got talent, they might let you sweep the floors. Move along."

  Entering Orario was like walking into a dream designed by a mad architect and a high-fantasy artist. The streets were paved with smoothed cobblestones that seemed to hum with the footsteps of thousands.

  The North Main Street was a canyon of activity. The buildings were multi-storied, built from cream-colored stone with terracotta roofs, their balconies overflowing with exotic flowers that Nyt couldn't name. Hanging signs in a dozen different languages swung in the breeze, weapons shops, potion stalls, and taverns that smelled of roasted meat and honey-ale.

  "Look at the infrastructure, Minerva," Nyt noted, his eyes darting to the street lamps. "Those aren't gas lamps. They're Magic Stone lamps. They’re using monster core as a decentralized power grid. It’s a circular economy of violence and utility."

  He passed a plaza. The crowd was a kaleidoscope of color. He saw adventurers in gleaming plate armor that reflected the sun, mages in flowing robes embroidered with silver thread, and merchants haggling with a ferocity that was its own kind of combat.

  The further north he went, the more the aesthetic shifted.You can hear hammering in a rhythm into a metal. The delicate flower boxes were replaced by heavy iron braziers. The smell of baking bread was overtaken by the sharp, metallic tang of hot iron and the heavy scent of coal.

  "Minerva, recalibrate visual sensors for low-light and high-heat environments," Nyt commanded. "We’re getting close."

  [Recalibrating... Thermal overlay active. Administrator, the heat signatures ahead are exceeding 1,500 degrees Celsius. There are multiple high-energy signatures concentrated in a single fortress-like structure.]

  "The Hephaestus Familia headquarters," Nyt whispered.

  The headquarters was less of a palace and more of a grand industrial complex. It was a massive, sprawling building of dark stone and reinforced steel, with chimneys that perpetually belched white steam into the sky. The sound was constant—a rhythmic, deafening clang-clang-clang that sounded like the heartbeat of the city itself.

  Nyt stood before the massive iron doors. Two guards, Level 2 adventurers by the look of their equipment, stood watch with halberds that shimmered with a faint magical sheen.

  "State your purpose," one said, his voice echoing under his helmet.

  Nyt took a deep breath. In his pocket, he gripped the jagged piece of debris—the remains of his Mechanical Core. He wasn't just some kid with a hammer. He was a Doctor of Physics, a Master of AI, and a man who understood the mechanics of the soul better than anyone in this world likely did.

  "I am Nyt," he said, pushing his glasses up the bridge of his nose. "I have a proposal for the Goddess Hephaestus. I’m not here to ask for a job. I’m here to offer her the blueprints for a new era of smithing."

  The guards shared a look. Normally, they would have chased a beggar in a lab coat away, but there was something in Nyt’s eyes, a cold, calculating brilliance that made them hesitate. It was the look of a man who didn't believe in "impossible."

  "Wait here," the guard said, turning to enter the building.

  Nyt turned back to look at the city of Orario one last time before he entered the forge. He saw the diversity, the magic, and the mystery. He saw a world that was waiting to be optimized.

  "Minerva," he whispered.

  “Yes, Administrator?”

  "Let’s show them what happens when you combine a Goddess's Falna with a 21st-century education."

  [Calculated probability of success: 99.9%. Let us begin the upgrade, Administrator.]

  The doors creaked open, “Go Inside the Goddess will meet you” the guard said and Nyt stepped into the heat, ready to rewrite the laws of the world.
