The swamp exploded with movement.
The moment Jason stepped forward, the entire formation collapsed inward around him like a trap finally snapping shut.
Water burst apart beneath lunging bodies as three Brine Spriggers converged at once from different angles.
Too fast.
Jason twisted sharply, barely slipping past the first creature as claws tore through the air where his throat had been a fraction earlier. The second hit immediately after, forcing him sideways through knee-deep swamp water.
Cold mud splashed across his chest.
The third came low.
Jason saw it at the last possible second.
Perception screamed. His heightened sense was one of his major key to survive since he landed here
He jumped backward instinctively—
—and the creature shot beneath him with terrifying speed, jaws snapping shut hard enough to crack against exposed roots.
Jason landed badly.
His boot slid violently across submerged bark.
Balance almost disappeared beneath him.
For one ugly second, he felt his body tilt too far sideways. His injured footing sank deeper into soft swamp mud while filthy water surged around his knees.
The pack noticed instantly.
Sharp clicking erupted through the fog.
Pressure.
Constant pressure.
They weren't trying to overpower him anymore.
They were trying to force mistakes.
Jason sucked in a sharp breath through clenched teeth and forced himself upright before another attack could arrive. Mud dripped from his sleeves. His side already hurt from earlier exchanges, and every rapid movement was starting to drag fresh exhaustion into his muscles.
But his breathing slowed anyway.
Not because he was calm.
Because panic would kill him faster.
His eyes moved rapidly through the swamp.
Water displacement.
Angles,recovery timing and attack rhythm.
The Alpha was controlling the pace perfectly.
Every time one Sprigger attacked, another repositioned before he could retaliate properly. No wasted movement. No reckless lunges. They were herding him deeper into unstable terrain.
Toward softer ground.
Toward worse footing.
Jason's jaw tightened.
"Annoying bastards…"
Another Sprigger burst from the fog.
Jason moved this time instead of reacting.
He stepped directly into the attack.
The creature clearly didn't expect it.
Its claws missed wide as Jason slammed his shoulder into its side and drove both of them into a half-submerged root cluster hard enough to spray stagnant water outward in all directions.
The impact staggered the creature for half a second,enough.
Jason activated Edge of Null instantly.
Dark distortion crawled violently across the knife edge.Cold pressure wrapped around his forearm.
[EDGE OF NULL ACTIVATED]
[AETHER ENERGY: 17 → 12]
Jason thrust upward—
—but the Alpha clicked.
Sharp and Violently
The Sprigger twisted unnaturally at the last second.
Jason's blade pierced through its shoulder instead of its throat.
The creature shrieked, although not dead.
The other two slammed into him immediately.
Jason barely crossed his arm in time before claws crashed against him, throwing him sideways through black swamp water.
Pain erupted through his ribs.
His body skipped violently across submerged roots before slamming hard into the mud.
For a second, the world blurred.
Cold water flooded his mouth.
Rotten swamp filth hit his tongue instantly.
Mud,water,roots .
Everything twisted together into chaos.
Then Perception dragged clarity back into focus.Jason rolled instinctively just before another set of claws tore downward where his head had been.
Wood splintered..
Jason forced himself upright, breathing harder now, he was just a thread length away from death.
The wounded Sprigger retreated immediately after taking damage.
Again.
The Alpha was pulling injured members away from direct engagement.
Protecting combat effectiveness and rotating pressure.
Jason stared through the fog toward the larger silhouette.
".....Tch"
"…Bastard creature learning too fast"
The Alpha clicked once.
Slow.
Measured.
And for the first time—
Jason understood something horrifying, this Alpha Brine wasn't just reacting to battle,It was reading him.
His preferred dodge direction.His aggression windows after activating Edge of Null,even his tendency to prioritize injured targets.
The realization settled coldly in his stomach.
This thing wasn't intelligent for a beast.
It was intelligent Period.
A pulse of unease crawled through him.
Not fear exactly.
The swamp fell briefly quiet again.
Then Jason noticed the formation changing, he was starting to feel the strain on himself. Earlier he was probably fighting on adrenaline but now the fight was dragging too long.
The remaining Spriggers spread outward wider than before, disappearing partially into the fog.
His eyes narrowed immediately.
"No…"
Perception stretched.
Water shifted behind him.
Left side,front, right—
Too late
One Brine Sprigger erupted upward from beneath the shallow swamp itself.
Jason barely twisted aside before claws ripped across his side instead of straight through his abdomen.
Pain flared instantly.
His breath caught violently.
Warm blood spread beneath his torn jacket.
The pack lost control for half a second.
The clicking became frenzied.
Excited.
Hungry.
Jason stumbled backward toward a thick cluster of exposed roots as another creature lunged directly toward the fresh blood scent.
This time he didn't retreat.
He planted his foot hard against submerged bark.
Edge of Null surged again.
[EDGE OF NULL ACTIVATED]
[AETHER ENERGY: 12 → 7]
The world sharpened.
The charging Sprigger opened its jaws—
—and Jason stepped forward violently instead of backward.
The knife drove straight upward through the roof of its mouth.
The distortion exploded through the creature's internal structure.
For the first time—
something broke.
A horrific cracking sound echoed through the swamp as dark fractures spread beneath the Sprigger's shell ridges.
The creature convulsed violently.
Its limbs jerked.
Water churned wildly around it.
Then it collapsed.
[BRINE SPRIGGER ELIMINATED]
[+5 EXP GAINED]
[AETHER ENERGY ABSORBED: +11]
Warm energy flooded through Jason instantly.
Not gradual,Immediate.
The exhaustion dragging at his body loosened slightly as cold pressure spread beneath his skin. His heartbeat steadied. His vision sharpened.
Jason exhaled slowly.
"…So that's how it works."
No hesitation .
The energy didn't return gradually.
It hit him like a conversion.Like the creature itself had become fuel.
The swamp around him shifted immediately.
The remaining Spriggers noticed.
Their clicking changed tone.
Faster, sharper and hungrier.
Jason tightened his grip on the knife.
"…Good."
The second one moved.
He didn't wait too.
Jason stepped forward through the swamp water before the creature fully committed to its lunge.
One strike.
One opening.
The blade cut into the joint seam beneath its forelimb.
The Sprigger shrieked.
Jason twisted the knife harder.
The creature collapsed sideways into the swamp water.
[BRINE SPRIGGER ELIMINATED]
[AETHER ENERGY ABSORBED: +12]
[CURRENT AETHER ENERGY: 24/100]
Jason blinked once.
The increase was immediate,not recovery.
Conversion like before.
He adjusted his stance slightly while blood continued dripping slowly from the wound in his side.
"…This is going to be snowball fast."
The third came in.
Then the fourth.
Each kill followed the same brutal rhythm.
Short movement,Break structure, Finish .
Jason stopped wasting motion.
Stopped overcommitting.
Every movement became tighter.
Sharper, and more efficient this time.
The swamp itself seemed to react to the shift in momentum.The clicking became unstable.
The remaining creatures no longer attacked recklessly. They repositioned constantly now, staying closer to the deeper fog.
Protecting something.
Jason exhaled through his nose.
The swamp was already changing.
The pack wasn't attacking randomly anymore.
They were retreating into formation.
Protecting something deeper in the fog.
Jason's eyes narrowed.
"…So there's an Alpha."
Then he saw it.
The Alpha Brine Sprigger.
It didn't step out like the others.
It revealed itself slowly.
The fog parted just enough to show its shape.
It was larger—but not just in size.
It was structured differently.
Its shell wasn't uniform like the others.
It was layered.
Segmented.
Like armor grown in phases rather than one piece.
Thin bone-like ridges ran along its spine, faintly pulsing beneath the dim swamp light.
Its forelimbs were longer.
Not for brute force.
For reach control.
And its head—
was partially split along the jawline, like it had adapted mid-growth.
Multiple pale eyes tracked Jason at once.
Not instinctively.
Methodically.
The other Spriggers didn't circle it.
They stayed slightly behind it.
Like it wasn't part of the pack.
But that thing was deciding the pack's outcome.
Jason felt it immediately.
"…This one is definitely different from the rest" He thought as he adjusted his stance.
The Alpha clicked once.
Low, controlled,not aggressive
Then the System pulsed violently across Jason's vision.
[WARNING]
[HIGHER THREAT RESPONSE DETECTED]
[ALPHA-TYPE ENTITY ENTERING DIRECT ENGAGEMENT]
The Alpha lowered itself slightly.
Not wild aggression.
A stance,
Measured, Prepared.
Jason slowly straightened despite the blood running down his side.
His grip tightened around the knife.
Breathing steadier now.
The Alpha suddenly moved.
Not forward.
Not back.
Sideways repositioning.
Testing angles.
Jason frowned slightly.
"…So you think too."
The Alpha suddenly stopped.
Its body compressed slightly—
like tension being stored beneath its shell.
Jason's Perception Lv.2 flared instantly.
Something was wrong.
The movement wasn't a charge.
It was preload.
Like stored force.
The Alpha suddenly shifted backward and fast.
Sharply, creating distance.
Jason stepped forward instinctively—
[SYSTEM ALERT]
[SIGNATURE MOVE DETECTED]
[BRINE SPRIGGER ALPHA — MIRE LUNGE]
Jason's eyes sharpened.
"…So that's your kill move."
The swamp exploded.
The Alpha shot forward in a compressed burst of force.
Not running.
Not jumping.
Fired motion.
Jason barely had time to react,He braced himself for impact.Feet planted in unstable swamp ground.
Knife raised.
Shoulder tight everything locked.
Impact came—
The swamp detonated on contact.
Mud and water erupted violently around them.
Jason was pushed backward half a step—
but didn't fall.
His arms shook under the pressure.
The Alpha was trying to crush through him in a single pass.
Jason gritted his teeth.
"…Tch."
Then—
he shifted sideways at the last possible second.
The Alpha's momentum tore past him instead of through him.
It landed behind him.
Jason twisted instantly.
"...Shit"
Knife came down.
The Alpha reacted—
but not perfectly.
Its landing had been disrupted slightly.Jason struck its shoulder seam.Then again into the exposed joint line.
The Alpha clicked sharply.
Unstable.
Jason didn't hesitate.
He stepped in.
One final movement.
Clean and direct.
The blade drove beneath its jawline into the core structural point hidden beneath the layered shell.
The Alpha jerked violently.
Tried to recover.
Failed.Its massive body collapsed heavily into the swamp water.
Still.
For several seconds—
nothing moved.
The remaining fog drifted silently between the trees while black ripples spread outward from the Alpha's corpse.The others quickly scrammed back into the fog in panic.
Jason stood there breathing harder now.
Knife lowered slightly at his side.
Cold swamp water dripped steadily from his sleeves.
Then—
the System responded.
[DAILY QUEST COMPLETE]
HUNT TARGET: BRINE SPRIGGERS (5/5)
BONUS TARGET: ALPHA ELIMINATED
REWARD: +30 EXP / +25 AETHER ENERGY / RESOURCE BONUS
Jason stared at the notification silently while his breathing gradually stabilized.
Then another message appeared.
[AETHER ENERGY ABSORBED: +25]
[CURRENT AETHER ENERGY: 65/100]
The energy surge hit harder than the others.
Not violent, more dense to be precise.It spread through his body in heavy waves, easing strain inside his muscles while sharpening the pressure beneath his skin.
Jason flexed his fingers slowly around the knife.
"…So the Alpha brine sprigger gives more Aether energy"
That explained why the System marked them separately.
Normal Brine Spriggers granted far less.
The Alpha granted more than double.
"...Risk and reward I guess"
The swamp remained completely silent around him.
No clicking.
No movement beneath the water.
The surviving tension from the hunt was gone now, like the entire area had finally released its breath after the Alpha's death.
Jason lowered the knife slightly.
His side throbbed harder now that adrenaline was fading.
He could feel every bruise returning.
Every strained muscle, every impact.
The swamp smelled worse after the fighting stopped.
Blood, rot and decay.
The corpses floating around him made the water look darker.
Jason looked down toward the nearest corpse.
Then the earlier notification resurfaced in his memory.
[CORE DETECTED]
LOW-GRADE BRINE CORE
COMPATIBILITY: RESOURCE / ENERGY ABSORPTION
[POTENTIAL LOOT]
Edible Predator Meat
Hardened Marsh Hide
Reinforced Tendon Fibers
Brine Core Fragment
Low-Grade Aether Residue
Jason crouched beside the nearest corpse carefully.
Pain immediately pulled through the wound along his side.
"…Tch."
The smell hit harder up close.
Rotten saltwater mixed with blood and wet decay.
"…Disgusting."
Still useful though.
That was what mattered.
Survival didn't care whether something was disgusting, only whether it had value.
He flipped the corpse over using the blade and finally got a clearer look at the internal structure beneath the shell.
The inside wasn't normal flesh.
Semi-transparent gel layers rested beneath hardened plates while thick tendon-like fibers connected the limbs together like braided cables.
His eyes narrowed slightly.
"That's why normal cuts barely worked…"
The outer structure absorbed impact while the softer internals redistributed force through the gel beneath the shell.
Efficient, Dangerous too.
Jason drove the knife beneath the chest cavity carefully and cut upward.
Dark fluid spilled into the swamp.
Then he saw it.
A small dim-blue object embedded deep near the creature's center mass.
The Brine Core.
It looked rough and unfinished, almost like cracked mineral fused with organic tissue.
Faint energy pulsed weakly beneath its surface.
The moment Jason touched it—
the System reacted instantly.
[LOW-GRADE BRINE CORE ACQUIRED]
RESOURCE TYPE: ENERGY MATERIAL
STATUS: STABLE
POTENTIAL USES:
AETHER ABSORPTION
EQUIPMENT REINFORCEMENT
CRAFTING MATERIAL
STRUCTURE ENHANCEMENT
Jason blinked once.
"…Structure enhancement?"
His eyes shifted instinctively toward the direction of the treehouse.
The damaged supports.
Weak flooring.
Exposed entry points.
The unstable platform creaking every time he moved across it.
The traps he still hadn't built yet.
Suddenly the resource mattered far more than simple energy gain.
He immediately began harvesting the rest.
The hardened Marsh Hide peeled away in thick wet layers after enough force. The Reinforced Tendon Fibers were worse—rubbery and difficult to cut cleanly—but noticeably durable once separated from the body.
Useful.
Bindings, maybe even trap mechanisms.
Structural reinforcement.
Jason continued silently while the swamp darkened around him.
One corpse after another.
Four normal Brine Spriggers.
One Alpha.
By the time he reached the Alpha corpse, his arms ached badly from repetitive cutting.
Blood from his side wound had mixed with swamp water until his clothes felt cold and heavy against his skin.
The Alpha's internals looked even stranger.
Its shell layers were denser.
Its tendons thicker.
And the core—
larger.
More refined.
Faint pale-blue veins pulsed beneath its cracked surface.
Jason stared at it briefly before storing it separately.
Instinct told him not to waste that one carelessly.
Several crude piles of harvested material rested beside him now.
Hardened Marsh Hide.
Reinforced Tendon Fibers.
Brine Core Fragments.
Predator Meat.
Low-Grade Brine Core.
Jason stared at the growing collection for a long moment.
Then reality hit him.
"…There's no way I'm dragging all this back manually."
The treehouse wasn't close.
And the swamp terrain alone would slow him to exhaustion before he reached halfway. Also he was bleeding from his sides, if he encounters another one of those brine spriggers who had a heightened sense of blood or any other dangerous creatures at all there was definitely no way he was making it out alive.
The adrenaline crash was beginning now.
His shoulders felt heavy.
His legs burned.
Even breathing felt rougher.
Jason frowned slightly.
Then suddenly stopped.
The System inventory.
Right.
He had almost forgotten.
Jason focused inward instinctively.
A faint distortion appeared beside him as the familiar interface surfaced.
[SYSTEM INVENTORY — ACTIVE]
[ 5 SLOT CAPACITY AVAILABLE]
Jason stared at it for a second.
Then slowly looked back down at the harvested materials.
"…You're telling me I carried all that junk manually earlier for nothing?"
Silence.
The System gave no response.
Jason clicked his tongue softly before reaching toward the nearest pile.
The materials vanished instantly into spatial distortion.
No resistance.
No weight.
Just gone.
"…Seriously."
He stored the next pile.
Then the next.
One after another until the swamp clearing was empty except for blood-stained water, torn roots, and drifting shell fragments.
Jason stood there quietly afterward.
The silence felt different now.
Not threatening.
Earned.
Somewhere deeper in the swamp, insects slowly resumed their distant noise.
The environment itself felt calmer.
Like a predator had died and the swamp knew it.His gaze lifted toward the dark trees ahead.
Somewhere beyond them sat the treehouse.Weak and unfinished.
Unprotected too.
Jason adjusted his grip on the blade and started walking through the swamp again.
Slow steps.
Heavy exhaustion.
But steady.
Branches scraped against his soaked clothes as he pushed through the fog-covered terrain. Every few minutes his side wound pulsed sharply enough to remind him how close the fight had been.
Yet despite that—
something had changed.
The swamp no longer felt like a place he was fleeing from.
Now it felt like territory he had survived.
Claimed through blood.
The thought settled strangely in his chest as the silhouette of the treehouse slowly emerged through the trees ahead.
Crooked supports.
Weathered wood.
Rough construction barely holding together above the marsh.
Before, it had looked temporary.
Fragile.
Now Jason looked at it differently.
Not as shelter.
As a base, at least until he figure out how to get back to that selection grounds.
He stopped briefly at the bottom of the structure and looked upward through the dark branches.
The treehouse creaked softly in the night wind.Too vulnerable,too easy to attack.
His eyes slowly narrowed.
