The deeper Adrian went, the heavier the air became.
Each step echoed.
Slow.
Measured.
Alive with tension.
The cave walls narrowed into a single passage.
Dark.
Silent.
Wrong.
Then—
THUD.
Adrian stopped.
"…That's not an echo."
THUD.
THUD.
Something was moving ahead.
Heavy.
Deliberate.
A faint red glow pulsed from the end of the tunnel.
Like a heartbeat.
[Warning: Boss Area Detected]
Adrian exhaled slowly.
"…So this is it."
His grip tightened around the bone weapon.
His only weapon.
Then—
He stepped forward.
The tunnel opened into a massive chamber.
And there—
It stood.
A towering beast.
Twice the size of the wolves.
Muscles coiled like steel.
Black fur matted with dried blood.
Eyes glowing like burning embers.
But what made Adrian freeze—
Was its shape.
It stood on two legs.
[Dungeon Boss: Bloodfang Alpha]
Level: 7
"…A… werewolf?"
The creature's gaze locked onto him.
Silence.
Then—
It smiled.
A low, guttural growl escaped its throat.
And in the next second—
It vanished.
Adrian's eyes widened.
"…Fast—!"
Too late.
BOOM.
The impact slammed into his side.
His body was sent flying across the chamber—
Crashing hard into the stone wall.
"Gah—!"
Pain exploded through his ribs.
Something cracked.
[Warning: HP Critical]
Adrian coughed, struggling to stand.
"…That… hit…"
"…wasn't normal…"
The boss approached slowly.
Confident.
Unhurried.
Like it knew the fight was already over.
Adrian wiped blood from his mouth.
"…No."
His legs trembled.
But didn't fall.
"…I didn't come this far to die here."
The Alpha stopped.
Watching him.
Curious.
Then it lunged again.
Faster than before.
Adrian activated everything he had.
[Skill Activated: Instinct Drive]
The world slowed.
Barely—
He twisted his body.
The claws grazed past his chest—
Tearing flesh.
"Too fast…!"
He couldn't keep up.
Not like this.
Another attack came.
Then another.
Then another.
Each one faster.
Stronger.
Deadlier.
Adrian was being overwhelmed.
"…Think…"
"…THINK!"
His eyes sharpened.
Tracking.
Learning.
Adapting.
"…There's a pattern."
The Alpha's movements—
Not random.
Not wild.
Precise.
It attacked—
Paused—
Shifted its weight—
Then struck again.
A rhythm.
Adrian inhaled sharply.
"…Got you."
The Alpha lunged again.
This time—
Adrian didn't dodge back.
He stepped forward.
The claws tore into his shoulder—
But he didn't stop.
"…Now!"
He drove the bone weapon forward—
Aiming for the heart—
CRACK.
The bone shattered.
Adrian froze.
"…What—"
The Alpha's eyes gleamed.
Its claw rose—
Ready to end it.
"…So this is it."
For a moment—
Everything slowed.
His thoughts.
His breath.
His heartbeat.
"…No."
Something deep inside him surged.
Not fear.
Not desperation.
Hunger.
[Hidden Condition Met]
[Skill Evolution Available]
Adrian's eyes widened.
"…Do it."
[Instinct Drive → Predator Instinct (Level 1)]
Everything changed.
The world snapped into clarity.
The Alpha—
Its muscles.
Its breathing.
Its movement—
All of it became visible.
Predictable.
Slow.
Adrian moved.
He slipped past the claw—
Effortless.
The Alpha's eyes widened.
For the first time—
It reacted.
Adrian grabbed a broken fang from the ground.
And in one fluid motion—
He stepped in—
Turned—
And drove the fang upward—
SHLK.
Straight through the Alpha's throat.
Silence.
The beast staggered.
Adrian twisted the fang.
And pulled it out.
The Alpha collapsed.
The ground trembled.
Then—
Stillness.
Adrian stood there.
Frozen.
Breathing hard.
Then—
[You have defeated Dungeon Boss: Bloodfang Alpha]
Light exploded around him.
[Level Up!]
[Level Up!]
[Level Up!]
[Level: 4 → 7]
Power surged violently through his body.
Stronger than before.
Sharper.
Heavier.
His wounds healed completely.
Even the broken ribs—
Gone.
Adrian exhaled slowly.
"…I won."
A new message appeared.
[Boss Reward Granted]
A weapon materialized in front of him.
Floating.
Dark.
Radiating power.
A dagger.
Black as night.
Its edge shimmering with a faint red glow.
[Item Acquired: Bloodfang Dagger]
Rank: Rare
Effect: +Agility, Bleed Effect
Adrian reached out.
And grabbed it.
The moment his hand touched the weapon—
A pulse ran through him.
Like it recognized him.
He smiled.
"…Now we're getting somewhere."
Another notification appeared.
[Dungeon Clear Complete]
A portal of light formed behind him.
Exit.
Adrian looked back at the battlefield.
Then at the dagger in his hand.
"…Next time…"
His eyes darkened.
"…I won't struggle this much."
And with that—
He stepped into the light.
