CHAPTER 1

  The forest was alive with sound, but to Hunter Kain, it was as familiar as the beat of his own heart. The chirping of cicadas hummed through the canopy, their voices echoing like a siren's call, daring anything brave or foolish enough to venture beyond the massive stone walls of the biome colony. The faint rustle of leaves whispered of predators unseen, but Kain’s trained eyes scanned the shadows, his bow steady in hand. Around him, his team moved in practiced silence, each step carefully placed to avoid crunching twigs or dry leaves.

  A faint vibration tickled the edge of Kain’s hunter perception, a warning only he seemed to notice. His lips tightened.

  We’re not alone.

  "Something’s close," he murmured, voice low but firm. The others froze in their tracks, weapons drawn and eyes scanning the darkened expanse.

  A blue rectangle of text appeared in Kain’s vision, bold and cold as it hung in the air before him:

  [Alert: Target Acquired – Titan Spider (S-Rank)]

  [Distance: 73 meters. Current Danger Level: ???]

  His grip tightened on his bow. "It’s close. Form up."

  The others obeyed instantly, drawing into a tight circle. Kain’s eyes flicked toward the surrounding trees, analyzing every shadow and flicker of movement. S-Rank. Even for an S-Rank Hunter like himself, this was no simple beast.

  Question marks on its danger level? We might be in trouble here…

  Unlike most hunters, who relied solely on combat instinct, Kain had spent countless nights studying the biological archives, analyzing patterns in apex predator behavior that others dismissed as irrelevant theory. The colony elders had often chastised him for "wasting time on dusty records" when he should be honing his physical skills, but that unconventional knowledge had saved his team more times than he could count. His mind raced through documented weaknesses of arachnid-class entities, calculating optimal strike points even as his body prepared for combat.

  Another rectangle flared to life:

  [Critical Weak Point Detected: Third joint on left leg]

  "I’ll draw its attention," Kain said, nocking an arrow tipped with venom harvested from a Razor Wasp. "Hit the legs if you can. Don’t let it pin you."

  They nodded, but the tension in their expressions was clear. The Titan Spider wasn’t just a monster—it was an apex predator in this biome, a nightmare born of the system's brutal evolutionary hand.

  A shadow moved; it was faster than the eye could track. The forest exploded into chaos as the Titan Spider descended from the canopy, its legs crashing down like spears. Kain’s arrow flew true, striking the weak point—but the spider’s enraged screech drowned out any satisfaction.

  The fight became a blur of motion and desperation. Kain moved with practiced efficiency, and every arrow was loosed with lethal intent. But the spider was relentless, its eight legs striking with deadly precision. One by one, his team fell, their cries swallowed by the forest.

  Kain stood alone, his quiver empty, his breaths ragged. Blood dripped from a gash across his chest, but he refused to fall. The spider loomed before him, its mandibles clacking in anticipation.

  Kain smirked bitterly. "Not today."

  With a roar, he charged, dagger in hand, aiming for the creature’s weak point. The joint glows red with vulnerability. The last thing he saw was the spider’s maw opening wide, its fangs sinking into his chest as darkness consumed him.

  Kain’s first sensation was cold.

  He gasped, his lungs seizing as if they’d forgotten how to breathe. His eyes snapped open, and he found himself lying on damp earth, the smell of fresh rain and scorched wood filling his nostrils. Above him, the sky was an eerie shade of violet, streaked with flashes of light that rippled like lightning across the heavens.

  Where the fuck am I?

  The answer came in the form of a blue rectangle that flickered into view:

  [System Reinitializing…]

  [Welcome to the Integration]

  His heart raced. The Integration? That was a term he’d only read about in ancient colony records, a moment whispered about in legend—the beginning of the system apocalypse a hundred years before his time—seventy-five years since he was born into the colonies.

  [Species: Human - Level: 1]

  [Class: None Selected]

  [Dao Compatibility: Determining…]

  Kain staggered to his feet, his body unsteady and unfamiliar. He glanced down, expecting the powerful frame of an S-Rank Hunter. Instead, he saw a lean, wiry form, like the body he’d possessed in his youth.

  This isn’t my body.

  The realization hit like a blow. He had died. He had felt the spider’s fangs pierce his chest, its venom burning through his veins. Yet here he was, alive and whole but impossibly in the past.

  Unauthorized reproduction: this story has been taken without approval. Report sightings.

  [Integration Complete]

  The sky rippled as the world seemed to shudder. Screams echoed in the distance, and Kain turned toward the source. People were running in chaos, their faces pale with terror. Trees twisted and grew unnaturally tall, their bark cracking with luminous veins of green. Insects, small and harmless just moments before, began to swell and shift, their forms grotesque and predatory.

  A new message appeared:

  [New Era Detected]

  [New Dao Available]

  Kain barely had time to process the words before a monstrous centipede the size of a small car emerged from the undergrowth, its many legs churning the ground as it charged toward him. Instincts honed by a lifetime of hunting took over. He dived aside, grabbing a steel construction pole that had snapped during the Integration from the ground as the creature’s mandibles snapped where he had been standing.

  The centipede lunged, its enormous mandibles gnashing toward him, black eyes glinting with predatory malice. Kain stumbled backward, his heel catching on a moss-covered log. He fell hard onto the ground, his breath leaving him in a ragged gasp as the creature charged, its sheer size blotting out the chaotic sky above.

  “No,” Kain thought, terror and defiance clashing within him. “Not again.”

  A surge of energy exploded from within him, raw and uncontrollable. His body convulsed as tendrils of lightning erupted outward, striking the centipede mid-lunge. The creature’s shriek cut through the air, its massive body illuminated in blinding arcs of electricity that scorched its chitinous armor to a blackened crisp. It collapsed into a spasming heap, the acrid scent of burnt flesh filling the air.

  [New Dao Discovered: Way of the Elemental Hunter – Awakened Lightning Dao]

  [Effects: Minor affinity with lightning. Bonus to tracking in storm conditions]

  Kain lay still for a moment, staring at his trembling hands as faint tendrils of lightning continued to dance along his fingertips. The moss covered log beside him smoldered, charred beyond recognition.

  As his breath steadied, he sat up, his thoughts racing. "Elemental Hunter," he muttered, the words of the system's prompt echoing in his mind. He closed his eyes and focused, piecing together fragments of ancient colony texts he had studied long ago.

  The irony wasn't lost on him. In the colonies, children were tested at age five for dao affinity, then systematically channeled into rigid vocational paths based on those results. He couldn't even remember what his original affinity had been—it was deemed irrelevant once he'd been classified as a Hunter. The colony's resources focused on only a handful of dao paths considered tactically essential; countless others were left to atrophy, their potential diminished through neglect.

  Yet here he was, awakening to a Lightning Dao—one of the elemental affinities that colony records spoke of with both reverence and fear. The professors had spoken of the Elemental Hunters—warriors who wielded the forces of nature itself. They were humanity's greatest weapon in the early days of the Integration.

  And they had been systematically hunted to extinction.

  Kain was a good student, he spent many hours with the teachers in his colony learning about all the ins and outs of the past. Something about the past deeply intrigued Kain, he found it resonated more with him than his time. While other hunters drilled combat forms, Kain had pored over fragmentary records of pre-Integration society—a world of inexplicable machines, global connectivity, and resources so abundant that people fought wars over abstractions rather than survival. It had all seemed so alien to him, yet strangely compelling, as though a part of him had always belonged to that vanished world.

  Kain’s fists clenched. He had read those stories in awe and sorrow, never imagining he would walk the path of those ancient warriors. But now, with the crackle of lightning still pulsing faintly within him, he realized that the Dao he had awakened—his Dao—might be the key to rewriting history.

  A blue rectangle flashed into his vision:

  [Level Up! You have reached Level 2]

  The notification brought an unexpected steadiness to Kain’s frayed nerves. His breaths slowed as he processed the words. He was still an F-Rank Elemental Hunter, but advancing even a single level meant something. A sense of progression. Growth. The system wasn’t just rebuilding him—it was offering him a path forward.

  Another notification appeared, sharper and more significant:

  [Class Advancement Available: Choose a Subset Path]

  [Options for Elemental Hunter - Lightning Subclass]

  [Stormcaller] – Master the tempest. Wield lightning to strike multiple foes and create powerful area-of-effect attacks. Strong against groups.

  [Thunderblade] – Channel lightning through weapons for devastating melee attacks. Exceptional speed and agility in close combat.

  [Stormstrider] – Harness the speed of lightning to enhance mobility. Gain unparalleled evasion and traversal abilities.

  Kain frowned, his analytical mind already at work. Each option carried immense potential but also came with inherent risks. [Stormcaller] offered raw power, but the thought of trading precision for chaos left a bitter taste. [Thunderblade] promised brutal efficiency, but committing to close-range combat was dangerous, especially against creatures like the centipede. [Stormstrider] piqued his interest with its focus on speed and adaptability—qualities that could save his life in a world of unknown threats.

  He sat cross-legged on the damp ground, ignoring the distant roars and screams that still punctuated the air. Lightning still hummed faintly through his body, a reminder of his newfound power. For a moment, he allowed his thoughts to drift back to his previous life in the colony.

  The walls of his home had stood tall and unyielding, keeping the horrors of the outside world at bay. As an S-Rank Hunter, he had been the protector of his people, venturing beyond those walls to hunt the system’s monstrous creations and bring back resources to sustain the colony.

  The colony’s elders had always spoken of the early days of the Integration—the chaos, the desperation, and the heroes who rose to meet the challenges. Among them, the Elemental Hunters had been legendary, their mastery of natural forces unmatched.

  And yet, their power had made them targets. With their cold, alien intelligence, the insects had systematically hunted them down, eradicating what they perceived as their greatest threat. By the time Kain had been born, the Elemental Hunters were little more than myths.

  And now I’ve become one.

  Kain’s gaze drifted to the shifting sky above. The purple hues streaked with jagged forks of lightning. His thoughts turned to his past life in the colony, where every choice had been a matter of survival. As an S-Rank Hunter, he’d always relied on a balance of offense and defense, leveraging his team’s skills to support his own. But now? Now, he was alone.

  His jaw tightened. "No one is coming to back me up this time."

  He returned his focus to the choices before him. Before his death, Kain would have immediately chosen strength over all else, but this time, it would have to be different. Rationality dictated caution, yet ambition demanded he seize every advantage. [Stormstrider] appealed to his survival instincts, offering mobility and evasion in a world where death lurked in every shadow.

  Finally, he exhaled and made his choice:

  [Selection Confirmed: [Stormstrider] Your speed and evasion are enhanced. Gain access to Unique Skill: Lightning Dash]

  [Lightning Dash]

  Harness the speed of lightning to move instantly over short distances. Lightning Dash can be used for quick repositioning, evasion, or to close the gap between you and your enemies. Charging the skill allows you to focus electrical energy into your body, turning your dash into a powerful, kinetic strike that damages and stuns targets upon impact.

  The system’s confirmation was accompanied by a rush of energy, like a live wire running through his veins. He felt lighter and faster, his reflexes sharper than before. A faint crackle of electricity danced around his legs as he stood, testing the newfound power. With a thought, he activated the ability, and in an instant, he surged forward, covering several meters in a blur of speed.

  The sensation was exhilarating. He could feel the system’s design aligning with his instincts, shaping him into something new.

  The ground beneath him began to tremble before he could delve deeper into his thoughts. The air grew heavy, charged with the same electric energy that now pulsed within him. The violet sky above seemed to ripple, folding in on itself. Trees erupted from the earth with impossible speed, their trunks thick and twisted, their canopies forming a dense, impenetrable expanse. Within moments, a massive forest had sprung into existence before him, stretching as far as his eyes could see.

  Before Kain did anything, he called on the System as he had done a million times in his past life to see his status screen:

  Name: Kain

  Level: 2

  Title(s): [Heart of the Storm] (???)

  Class: Elemental Hunter (F-Rank)

  Subclass: Stormstrider

  Affinity: Lightning (Minor)

  Skills: [Lightning Dash] (I) [Hunter’s Sense] (Passive)

  Kain’s eyes moved up and down the status screen, he noticed [Hunter’s Sense] his spiritual sense that connected him to the earth, his ability to track and map the world around him had stayed with him from his previous life, that was definitely more than ideal.

  Kain’s gaze lingered on the title line. “Heart of the Storm?” he murmured, tasting the words. Memories of the centipede’s demise flashed in his mind—the surge of power, the blinding crackle of lightning reducing the creature to ash.

  “Maybe that’s how I killed it.” He clenched his fist, feeling a faint hum of energy under his skin. Whatever this title was, it wasn’t like anything he’d known before. It felt raw, dangerous, yet alive—a force waiting to be wielded.

  A flicker of a grin crossed his face. “If this is mine, I’ll make it unstoppable.”

  He rose to his feet, turning his attention back to the massive forest that now loomed before him, its depths teeming with danger and discovery.

  Kain stepped toward the towering trees, his lightning-charged body brimming with apprehension and determination.

  I must discover the secrets of how the colonies were created. The answer will be in civilization, but first… I need to get stronger.

  Whatever awaited him within that forest, he knew one thing for sure: his journey had only just begun.
