Deep underground beneath the capital city—
Silence filled the dungeon corridor outside the boss chamber.
Ren and Lyra rested quietly near the massive stone gates.
A small camp lantern illuminated the dark corridor while both prepared themselves for the coming battle.
Ren sat against the wall while rechecking his Beretta M9 carefully.
Magazine loaded.
Suppressor attached.
Ammo count stable.
Meanwhile, Lyra quietly drank water while holding her wand close to her chest.
The atmosphere felt tense.
Heavy.
Dangerous.
Boss monsters were completely different from normal dungeon creatures.
Even beginner bosses could wipe out entire adventurer parties.
Ren tore a piece of dried meat and looked toward the massive stone doors.
"You nervous?"
Lyra stayed silent for several moments.
"…A little."
Honestly—
Ren was nervous too.
But years of military combat had taught him something important.
Fear itself wasn't weakness.
Losing control because of fear was.
Before either of them could continue—
Far away inside the capital city—
Another dangerous conversation was already beginning.
Inside the Royal Knight and Mage Academy of Kingdom of Valdoria—
A beautiful young woman sat elegantly upon a luxurious royal chair near a balcony garden.
Golden morning sunlight illuminated her long crimson hair while expensive silk clothing draped gracefully across her figure.
In one hand she held a delicate porcelain teacup decorated with gold lining.
Beside her—
A maid stood quietly with her head lowered respectfully.
The noblewoman calmly sipped her tea.
Then finally spoke.
"The rumors about the adventurer…"
Her voice sounded elegant yet cold.
"The one who cleared a dungeon alone."
The maid answered immediately.
"Yes, Lady Seraphina."
"His name is Ren."
"A newly registered adventurer."
"He reportedly completed a solo dungeon raid within a single day."
Lady Seraphina slowly smiled.
Interesting.
Very interesting.
Talented commoners occasionally appeared.
But someone capable of solo dungeon raids immediately after registration?
That was abnormal.
Potentially useful.
Seraphina slowly placed down her teacup.
"Find out more about him."
"Yes, my lady."
"If he truly possesses talent…"
A faint ambitious smile appeared on her face.
"Then I'll simply make him serve me."
The maid lowered her head further immediately.
After all—
Lady Seraphina desired the throne itself someday.
And powerful tools were always necessary for power.
Meanwhile—
Inside the royal palace itself—
A completely different atmosphere existed.
Luxury.
Perfume.
Alcohol.
And filth.
Inside a large royal bedroom—
The kingdom's only prince sat lazily upon a golden chair.
Fat.
Sweating heavily.
A disgusting lecherous smile covered his face.
Beside the prince—
A naked cat beastwoman trembled quietly on the floor.
A slave collar wrapped tightly around her neck while bruises covered parts of her body.
The prince rested one foot arrogantly against her chest while drinking expensive wine lazily.
Fear and humiliation filled the beastwoman's eyes.
But resistance was impossible.
Nearby, a royal servant kneeled respectfully.
"Your Highness."
"The Silver Wolf Tribe has officially been confirmed destroyed."
The prince immediately became interested.
"Oh?"
The servant continued.
"The daughter of the eastern duke survived."
"She was later captured and sold into slavery."
The prince's eyes widened greedily.
"A silver wolf noblewoman?"
His breathing immediately became heavier.
"Beautiful?"
"According to reports… extremely."
The prince grinned disgustingly.
"Good."
"Prepare funds from the royal treasury secretly."
"I'll buy her personally once she returns to the capital."
The terrified beastwoman beneath his foot trembled harder after hearing his words.
The servant hesitated slightly.
"…It may require three or four days to move that much money without alerting His Majesty or the noble ministers."
The prince waved casually.
"Do it anyway."
His smile widened further.
"A silver wolf duchess…"
"I wonder how long she'll last before begging."
Neither the prince nor the servant realized one important thing.
Lyra Valeford had already been purchased.
And the man who now stood beside her—
Was far more dangerous than either of them imagined.
Back inside the dungeon—
Ren slowly stood.
"It's time."
Lyra nodded firmly.
The two approached the giant stone gates carefully.
Then—
The doors slowly opened.
A massive hall appeared beyond them.
It resembled a ruined royal throne room.
Broken pillars lined both sides of the chamber while ancient banners hung torn across the walls.
And at the very center—
Sat the boss monster.
A gigantic ogre.
Nearly four meters tall.
Two horrifying faces covered its massive head.
Four muscular arms rested against a gigantic throne made from monster bones.
And beside it—
A massive greatsword nearly the size of an adult human.
The moment the creature noticed them—
All four eyes opened simultaneously.
Heavy killing intent exploded throughout the chamber instantly.
Lyra's body stiffened slightly.
"Ren…"
The ogre slowly stood from its throne.
BOOM.
The entire hall shook beneath its footsteps.
Then—
The monster roared.
The sound alone shook dust from the ceiling.
And the battle began.
Lyra attacked first.
"Wind Spear!"
Compressed wind magic shot forward instantly.
The spell struck the ogre directly—
But barely pierced its thick skin.
The monster roared angrily and charged.
Fast.
Way too fast for its size.
Ren immediately fired.
PFFT. PFFT. PFFT.
Suppressed bullets slammed into the ogre's chest and face repeatedly.
But unlike goblins—
The boss monster endured them.
Its skin toughness was absurd.
The ogre swung its gigantic sword downward violently.
BOOOOM!
The floor exploded apart.
Ren barely pushed Lyra away in time.
Stone debris scattered everywhere.
"Keep your distance!" Ren shouted.
Lyra immediately repositioned while gathering lightning mana.
As the battle continued—
Ren finally understood something important about this world's dungeons.
Clearing ordinary dungeon floors and defeating a dungeon boss were completely different things.
The difficulty increase was absurd.
The goblins and hobgoblins outside had felt manageable.
Dangerous, but controllable.
But this monster—
This was an entirely different level of combat.
Its durability.
Strength.
Speed.
Killing intent.
Everything drastically surpassed normal dungeon creatures.
And suddenly—
Ren realized why most adventurers never truly cleared dungeons.
Most raid parties only hunted monsters roaming the upper floors.
Safe kills.
Small profits.
Minimal risk.
Very few actually challenged the boss rooms hidden deep inside.
Because boss monsters were designed to slaughter unprepared adventurers.
One mistake meant complete party annihilation.
Even Ren—with modern weapons and military experience—
Was barely surviving.
If not for Lyra's magic support and his system abilities—
This fight could have easily ended in death.
And for the first time—
Ren fully understood why successful dungeon clears brought massive fame, wealth, and influence within this world.
The battle quickly became chaotic.
Wind blades.
Lightning strikes.
Gunfire.
Explosions from collapsing pillars.
The four-armed monster attacked relentlessly from impossible angles.
One mistake meant death.
Then suddenly—
The ogre lunged toward Lyra.
Too fast.
Ren moved instantly.
He shoved Lyra aside—
But the massive sword slashed directly across his left arm.
SHHK.
Blood exploded across the floor.
"REN!"
Pain shot through his entire body instantly.
His arm nearly went numb.
But Ren forced himself upright immediately.
Military instinct overrode pain.
Retreat later.
Survive first.
The ogre charged again.
And Ren's eyes sharpened coldly.
Enough.
He grabbed one grenade from storage instantly.
Pulled the pin.
Then threw it directly toward the charging ogre.
The monster barely had time to react.
BOOOOOOM!!
The explosion violently shook the entire throne hall.
Fire erupted outward alongside a terrifying shockwave.
Stone pillars cracked.
Dust exploded across the chamber.
The deafening sound echoed endlessly through the dungeon.
Even Lyra froze completely for several seconds.
Her enhanced beastwoman hearing made the explosion far worse for her.
Her ears rang painfully.
Her body momentarily went numb from both the shockwave and overwhelming sound.
The massive ogre staggered backward through flames and smoke.
Then—
Its gigantic body finally collapsed heavily onto the ruined throne.
Silence followed afterward except for falling debris and distant ringing.
The battle had lasted nearly four hours.
Four brutal hours of nonstop fighting inside the ruined throne hall.
Collapsed pillars.
Broken stone.
Blood-covered floors.
The entire chamber looked like a battlefield after a war.
Ren leaned heavily against shattered rubble while breathing roughly.
His left arm burned painfully from the deep wound.
Meanwhile, Lyra looked completely exhausted.
Sweat covered her body while her mana reserves had nearly reached their limit.
Even standing seemed difficult now.
Boss raids truly were monsters of a different category.
Normal adventurers would have died long before reaching this point.
And honestly—
Even Ren barely survived despite possessing modern weapons and military combat experience.
The only reason they succeeded was because both covered each other's weaknesses perfectly during battle.
Gunfire for precision and lethal damage.
Magic for crowd control, mobility, and support.
Without teamwork—
This raid would have ended in death.
Then suddenly—
A powerful warmth spread throughout Ren's entire body.
Blue light erupted around both him and Lyra simultaneously.
Ren's eyes widened slightly.
The deep wound across his left arm rapidly closed before his eyes.
Blood disappeared.
Torn flesh regenerated instantly.
Even his exhaustion vanished almost completely.
Nearby, Lyra stared at her own body in shock.
The bruises, cuts, and mana exhaustion covering her body disappeared rapidly beneath the blue light.
Her breathing stabilized instantly.
"What…?"
Blue notifications flooded Ren's vision immediately afterward.
[LEVEL UP]
Level 1 → Level 9
Bonus Rewards Applied
• Full Health Recovery
• Full Stamina Recovery
• Mana Recovery (Party Shared)
Lyra blinked repeatedly while touching her healed arms.
"My injuries…"
Ren slowly clenched his restored left hand.
Not even a scar remained.
The exhaustion from the four-hour battle had vanished completely.
Even the pain disappeared.
Meanwhile, Lyra looked toward Ren with disbelief.
"Your strange power healed both of us?"
Ren exhaled slowly.
"Looks like leveling up restores the body."
Honestly—
That alone was already absurdly overpowered.
In a world where healing magic remained expensive and rare—
Instant full recovery after battle could completely change dungeon warfare itself.
And somewhere deep inside Ren's mind—
He quietly realized something dangerous.
The stronger he became—
The more unfair his existence would become within this world.
Then finally—
The familiar blue system notifications appeared before Ren's eyes.
[Boss Monster Eliminated]
[Dungeon Boss: Two-Faced Ogre Tyrant]
System Rewards:
• Arsenal Shop Unlocked
• Weapon Unlock Fragment ×5
Then another notification appeared.
[Boss Loot Acquired]
• AK-47 Blueprint ×1
• 200 Gold Coins
• Ogre Teeth ×12
• Ogre Armor Set ×1
• Ogre Greatsword ×1
• Ogre Testicles ×2
• Ogre War Club ×1
Ren's eyes widened slightly.
AK-47 Blueprint.
A weapon blueprint dropped directly from the boss monster.
Not the weapon itself—
But the production blueprint.
Meaning—
As long as enough materials existed—
He could potentially manufacture unlimited AK-47 rifles through the system.
Blue particles flickered across the battlefield as physical loot materialized around the dead boss.
The gigantic ogre greatsword crashed heavily onto the stone floor.
Nearby—
A massive black iron war club appeared as well.
The weapon looked crude.
But the amount of metal used in its construction was enormous.
Ren's eyes sharpened instantly.
Metal.
Resources.
Crafting material.
Even the ogre armor itself contained enough usable metal to create multiple weapons later.
The system blueprint likely required raw materials rather than currency.
Which meant—
Monster equipment could potentially become military manufacturing resources.
Rifles.
Ammunition.
Future weapons.
The possibilities suddenly expanded enormously.
Meanwhile, Lyra stared at the battlefield in complete disbelief.
The armor alone looked worth a fortune.
The giant sword could probably be auctioned to nobles or knight commanders.
And 200 gold coins—
Was enough money for ordinary people to survive for years.
Yet Ren's focus remained elsewhere.
On the future.
On the weapons now slowly becoming possible.
And somewhere deep inside his mind—
The image of modern warfare had already begun taking shape within this fantasy world.
