Left alone in the dense, metallic-barked forest, Kyle quickly realizes that survival in this fantasy realm is a brutal, physical endeavor. After discovering a rusty helmet and a skeletal hand desperately clutching a metallic mining rod, Kyle accidentally activates the rod's high-speed drilling function, realizing it drains his own Ether to function. His first true test arrives in the form of a Narvonian Worm, a terrifying, ten-meter-long snapping turtle hybrid that extends its neck with monstrous speed. The beast clamps its jaws around Kyle's lower leg, severing his limb below the thigh in a sudden, sickening reversal. In a state of pure panic and primal hunger, Kyle devours the raw chunks of turtle flesh stuck to his mining drill, triggering his Predator's Being trait to regenerate his bones and muscles like a lizard. Fully healed but starving, Kyle faces a pack of fire-spitting wolves that arrive to scavenge the meat, leading to a frantic, silent struggle for the precious, Ether-rich food. Driven by a cocktail of adrenaline and drug-like euphoria from the meat, Kyle ignores his rational mind, jumps directly onto the giant worm's head, and gets pulled into its dark shell. Inside the claustrophobic darkness of the beast's maw, Kyle's spine is shattered against the stone walls, but he desperately feeds on the creature's blood to reactivate his dying drill, grinding its brain into a gory slurry. He passes out in a heap of blood and excrement, unaware of the local hunters tracking the very beast he just slaughtered. When he finally awakens, he finds himself trapped inside the giant worm's hollowed carcass, gorging himself on its seemingly endless meat and developing a defined six-pack without lifting a finger. His peace is shattered when a group of professional hunters deploys a sedative gas, knocking him unconscious and dragging his naked, grimy body back to the local city of Theodor's Rest, where he wakes up behind a vibrating magical forcefield, facing a prison guard speaking an entirely foreign language and gesturing toward a future of forced labor.

After being bailed out of prison by the elite hunter Samson, Kyle is introduced to the local Hunter Hall and begins a grueling apprenticeship. Under the aggressive tutelage of the shield-wielding veteran Nervon, Kyle is thrown directly to the fire-spitting wolves to test his resolve. During a chaotic skirmish, a fireball blasts Kyle in the torso and face, but the agonizing heat only fuels his rage as he drops his sword, gouges the wolf's eyes out with his thumbs, and tears its throat open with his bare hands. Devouring the beast's leg to heal his horrific burns, Kyle earns the respect of his peers and begins operating as an independent hunter, utilizing his enhanced sense of smell to track down hidden Golem incubators. Driven by a hunch about his original drop point, Kyle spends his rest days digging a massive hole into the stony hill where he first arrived, eventually breaking his mining tool against a horizontal wall of black bricks. When he speaks the name Theodor aloud, the floor collapses beneath him, dropping him into the ancient, torch-lit inheritance crypt of Lord Theodor, a legendary Master Artificer. Here, Kyle meets Sulfur, a colossal golem with a butler-like demeanor and a penchant for terrifying jokes, who guards a massive stone dragon named Hieronymus. Sulfur explains that Kyle has stumbled upon an inheritance crypt meant to preserve Theodor's life's work, but leaving is impossible unless he passes a series of dangerous trials. Trapped between a stone dragon and a giant golem, Kyle has no choice but to grab a massive two-handed mining hammer and step through the door to face his destiny. He enters the first trial, where he must mine through a twenty-meter-thick wall of self-regenerating stone that heals its wounds like a living organism. By consuming the sweet, Ether-rich yellow veins within the rock, Kyle gains a drug-like surge of energy, violently smashing through the wall before easily pulverizing a sword-wielding golem in the second trial, only to find himself standing before a breathtaking, crystal-filled cavern that demands he master the delicate art of soul-infused mining.

Within the deep cavern of the third trial, Kyle spends two weeks mastering the unique properties of various magical ores, using his soul to soften Spirit Spring Ore into edible lollipops and upgrading his hammer with Craftsmen's Stone. After bathing in Silver's Fluid to refine his physical quality and advancing to the Mid Squire realm, Kyle enters the fourth trial, bypassing the specialized career paths to choose the allrounder gate that enhances all four Aspects of Power. To solve the trial's riddle, Kyle must stand directly inside a blazing pit of coal, using his enhanced mind to calculate a massive algebraic equation while his flesh sweats in the magical heat. Having successfully deciphered the hidden line, Kyle descends a fifty-foot drop into the final trial, discovering a massive, subterranean ruined city made of brown crystals. The ruins are populated by scaly Spitters and giant, stone-like Ore Fiends that jump like monstrous frogs and obliterate everything in their path. After accidentally provoking the beasts, Kyle is chased into the city's central spire, where he climbs to the top and encounters the white Ore Fiend, a colossal creature of the Second Realm that has consumed the true Inheritance Crystal. As the voice of the deceased Lord Theodor suddenly echoes in his mind, warning him of the creature's unstoppable power, Kyle realizes he is trapped at the top of a three-hundred-meter spire with a rock-eating monster. Desperate, Kyle tricks the beast into tumbling down the spiral staircase, using his hammer as a ramp to launch the boulder-shaped fiend into a freefall. Seizing his only chance, Kyle leaps from a height of seventy meters, aiming his heavy hammer directly at the cracked armor on the beast's back, bracing himself for a collision that will either grant him the ultimate inheritance or shatter every bone in his body. The impact is catastrophic, disintegrating his hammer, fracturing his spine, and splintering his legs into useless mush. Yet, as the white behemoth prepares to swallow him, the shattered core of Kyle's hammer activates, draining the beast's stone body of its Ether and reducing the monster to a heap of harmless rubble, leaving Kyle to consume the debris and heal his mortal wounds while a spectral, paranoid voice takes permanent residence inside his brain.

Returning to the surface after his three-week disappearance, Kyle reunites with Samson's team under the cover story of a magical explosion, hiding his newly acquired Sandspeak fluency and upgraded weaponry. He resumes his intensive physical training with Nervon, learning to predict his opponent's movements in battle while secretly mining in his private cave under Theodor's guidance. While patrolling the deep forest, Kyle is ambushed by a highly trained Fighter sent by a corrupt Baron, a deadly assassin who moves with terrifying speed and agility. Realizing he cannot hit the stealthy opponent in a straight fight, Kyle screams for help to attract a dangerous Sparkly Bear, creating absolute chaos in the woods before fleeing toward the city. The bear mauls the assassin, but Kyle returns to deliver the final blow, using his hammer's pick to destroy the man's Center and strip him of his Ether. When the authorities investigate the corpse, Kyle casually claims the bear did all the work, maintaining his low-profile disguise while secretly preparing for a grand conflict against the corrupt nobility. This calculated deception highlights Kyle's evolving strategic mind, showing that he is no longer just a reckless brute but a cunning survivor who understands how to leverage the environment to defeat superior foes. By allowing the Sparkly Bear to do the heavy lifting, he keeps his true power hidden from the Baron's spies while securing a valuable corpse that provides crucial clues about the local political conspiracy. Back in the safety of the Hunter Hall, Kyle continues to balance his public life as a humble apprentice with his private cultivation as a Master Artificer's heir, knowing that the corrupt forces operating in the shadows will eventually return to finish the job, forcing him to either master his dual-nature abilities or fall victim to the ruthless power struggles of the Skysand Kingdom.
