The moment Ren and Lyra stepped inside the Adventurer Guild—
A blue transparent screen suddenly appeared before Ren's eyes.
[Party Formed Successfully]
Party Members: • Ren Viren
• Lyra Valeford
Reward Granted: • Wireless Radio Set ×2
Another notification appeared immediately afterward.
[New Mission Available]
Objective: Kill 50 Monsters within 2 Hours
Reward: Party Hunt Experience Share Enabled
And then—
A third notification appeared.
[Feature Unlock Approaching]
Quest: Kill a Boss Monster during Dungeon Raid
Reward: Arsenal Shop Unlock
Ren's eyes narrowed slightly.
Arsenal Shop.
That sounded important.
Very important.
But before he could think further—
The guild receptionist interrupted politely.
"Your companion's registration has been completed."
Lyra officially received her Adventurer Guild identification plate moments later.
F-Rank.
Same as Ren.
Though honestly—
After seeing her mana control earlier, Ren doubted she would remain low-ranked for long.
The two left the guild soon afterward and headed toward another dungeon located near the outer district of the capital.
Unlike the Ashen Frontier dungeon from yesterday—
This dungeon specialized in goblin-type monsters.
Goblin.
Hobgoblins.
Small monster tribes.
Primitive weapons.
Basic magic users.
A common beginner raid location.
While walking through the city streets, Ren finally asked something that had bothered him since reincarnating.
"So... what exactly is this world called?"
Lyra blinked slightly before answering.
"The continent is called Eryndor."
Ren listened carefully.
"There are multiple nations across it."
She pointed ahead while explaining.
"Toward the western coast beyond the ocean are the human kingdoms."
"There are currently two major human nations."
"The Kingdom of Astravia."
"And the Kingdom of Valdoria."
Ren already recognized the second name.
The greedy kingdom they currently lived in.
Lyra's expression became colder while speaking about it.
"Astravia is relatively peaceful."
"But Valdoria values wealth, expansion, and slavery above everything else."
"That's why the slave markets here are massive."
Ren silently memorized everything.
Lyra continued.
"Further east are the Beast Nations."
"There are two major beast nations."
"My homeland—the Kingdom of Fenrisgard."
"And beyond our eastern border is the Kingdom of Raegor."
She paused briefly.
"After Raegor…"
"There's only ocean."
Ren quickly organized the map mentally.
Ocean.
Human kingdoms.
Beast nations.
Then ocean again.
Interesting geography.
But then Lyra pointed northward.
"And above the Beast Nations…"
"The Elven Federation."
Ren looked toward her curiously.
"Elves?"
Lyra nodded slowly.
"The elves separated themselves long ago."
"They rarely interact with outsiders."
"But their lands contain ancient forests, magical resources, and powerful mana veins."
Her expression darkened slightly.
"Valdoria wants direct access to elven territory."
"And enslaving elves is considered extremely profitable among human nobles."
Ren's eyes narrowed slightly.
So that explained part of the political tension.
Valdoria wanted expansion routes through the Beast Nations toward the elves.
Which meant—
Eventually conflict was inevitable.
Before Ren could ask more questions—
The dungeon entrance finally appeared ahead.
A massive cave entrance reinforced with stone walls and Adventurer Guild markings.
Several rookie adventurer parties prepared outside nervously.
Most immediately moved aside after recognizing Ren.
"The solo raid guy…"
"Apparently he cleared a dungeon alone…"
"And that beastwoman beside him…"
Whispers spread again.
Ren ignored them completely.
Instead, the moment they entered the dungeon—
Another blue notification appeared.
[Mission Timer Started]
Remaining: 1 Hour 59 Minutes
Monster Kills: 0 / 50
Ren immediately opened his storage.
Blue particles flickered.
Two strange black communication devices appeared in his hands.
Lyra stared curiously.
"What are those?"
"Wireless radios."
She tilted her head.
"What does that mean?"
Ren handed one toward her.
"These let us communicate instantly over long distances."
Lyra blinked.
"…Without magic?"
"Yeah."
Her expression immediately became suspicious again.
"That sounds impossible."
Ren spent several minutes teaching her basic usage.
Buttons.
Push-to-talk.
Volume adjustment.
Communication range.
Emergency channel.
The more Lyra learned—
The more shocked she became.
"This has no mana crystals…"
"No magic formation…"
"How are voices traveling through it?"
Ren shrugged casually.
"Technology."
Lyra looked at the radio again as though it were some ancient divine artifact.
Even magical communication tools in this world were expensive and limited.
Yet Ren casually possessed two portable communication devices.
It honestly felt absurd.
Eventually, they moved deeper into the dungeon.
Dark stone tunnels stretched endlessly ahead while faint growls echoed through the cave system.
Then—
A goblin appeared.
Small.
Green-skinned.
Rusty sword.
Weak.
Ren immediately raised his Beretta M9.
PFFT.
The suppressed gunshot echoed softly through the tunnel.
The goblin's head snapped backward instantly before collapsing.
Lyra's ears twitched slightly.
Then her expression visibly relaxed.
"Much better."
Soon afterward—
The hunt truly began.
Goblins flooded through the tunnels in groups.
But this time Ren wasn't fighting alone.
Lyra raised her wand gracefully.
Blue mana gathered instantly.
"Wind Spear."
Compressed wind magic pierced directly through two goblins at once.
Then lightning followed immediately afterward.
CRACK.
A hobgoblin collapsed smoking onto the dungeon floor.
Ren watched briefly.
Honestly—
Lyra was extremely talented.
Her casting speed.
Mana control.
Combat instincts.
All absurdly good.
Combined with enhanced beastfolk physical abilities—
She truly was abnormal.
The two moved rapidly through the dungeon together.
Gunfire.
Wind magic.
Lightning strikes.
Monster corpses accumulated continuously behind them.
After nearly an hour of nonstop hunting—
The dungeon floor had become littered with goblin corpses.
Ren silently checked the loot notifications visible only to him.
[Loot Collected]
• 47 × 9mm Bullets
• Goblin Ears ×40
• Goblin Fangs ×40
• Hobgoblin Teeth ×10
• Weapon Unlock Fragment ×2
A faint smile appeared on Ren's face.
The ammunition supply had increased nicely.
Especially the weapon fragments.
Meanwhile, Lyra noticed him staring blankly into empty space again.
Her wolf ears twitched slightly.
"…Your strange power again?"
Ren nodded casually while storing everything directly into system storage.
Blue particles flickered briefly as all collected materials vanished instantly.
Lyra stared at the disappearing items with curiosity.
"I still don't understand those small metal things your weapon uses."
"Bullets."
Ren removed one 9mm round from storage and handed it toward her.
Lyra carefully inspected it.
Small.
Compact.
Made entirely from strange metal.
No mana signature.
No magical engraving.
Yet somehow capable of killing monsters instantly when fired from Ren's weapon.
Her expression became increasingly confused.
"How does something this small contain enough power to kill monsters?"
Ren answered calmly.
"Controlled explosion."
Lyra immediately looked even more horrified.
"…Inside your weapon?"
"Yep."
"That sounds unsafe."
"It usually is."
Lyra quietly returned the bullet while muttering softly.
"Your entire world sounds insane…"
Then her eyes shifted toward another item Ren briefly mentioned.
"Weapon fragments?"
"Materials for future upgrades."
Lyra looked toward him curiously.
"So stronger monsters drop better upgrades for your weapons?"
"Looks like it."
That honestly excited Ren slightly.
Because if hobgoblins already dropped weapon fragments—
Then stronger dungeon bosses might unlock far more dangerous military equipment later.
Rifles.
Grenades.
Machine guns.
Maybe even armored vehicles someday.
The possibilities felt endless.
Eventually—
The two finally stopped before a massive stone gate deep underground.
Cold air leaked from the gaps beneath it.
A boss room.
Before entering, Ren finally stopped walking and looked toward Lyra seriously.
The massive stone gate stood only a few meters ahead now.
This wasn't the time for mistakes.
Especially friendly fire.
Ren reached into system storage again.
Blue particles flickered briefly.
The suppressed Beretta M9 appeared in his hand alongside a single 9mm bullet.
Lyra's crimson eyes immediately focused on both objects.
"You've been curious about this thing for a while now, right?"
Lyra nodded slowly.
Ren held the bullet carefully between his fingers.
"This is called a bullet."
Then he pointed toward the pistol.
"And this is the gun."
Lyra listened carefully.
Ren crouched near the dungeon wall and started drawing rough diagrams on the ground using a small stone.
"This part here is the barrel."
He pointed toward the front of the pistol.
"The bullet stays inside the gun before firing."
Then he tapped the bullet casing.
"Inside this small metal shell is explosive powder."
Lyra's ears twitched immediately.
"An explosion again…"
"Small controlled explosion," Ren corrected calmly.
"When I pull the trigger…"
He pointed toward the mechanism.
"The gun creates a spark."
"That spark ignites the explosive powder inside the bullet."
"Then the explosion pushes the metal projectile forward at extremely high speed."
Lyra's eyes widened slowly as realization formed.
"So your weapon throws metal using explosions?"
"Exactly."
"And because the speed is absurdly high…"
Ren pointed toward a goblin corpse nearby.
"It pierces flesh, bone, armor, and sometimes even magic protection."
Lyra stared at the pistol with newfound caution.
"That's terrifying."
Ren shrugged casually.
"In my world, this is considered a normal sidearm."
"…Your world was insane."
"That's accurate."
Ren then looked directly into Lyra's eyes.
"But there's something important."
His tone became serious.
"Never stand in front of my gun while I'm firing."
Lyra immediately nodded.
"The bullet moves too fast to stop after firing."
"If you accidentally cross my line of fire…"
He paused briefly.
"You'll die before realizing what happened."
Silence filled the dungeon corridor for several moments.
Lyra slowly looked at the small bullet in her hand again.
Something so tiny.
Yet capable of instant death.
No mana.
No chant.
No magical circle.
Just pure destructive force created through technology.
Eventually, Lyra handed the bullet back carefully.
"I'll stay beside you or behind you during combat."
"Good."
Ren reloaded the pistol calmly.
CLICK.
The sound echoed softly through the corridor.
Then both of them turned toward the massive boss gate once again.
A heavy pressure leaked from beyond it.
The atmosphere itself felt different compared to the rest of the dungeon.
Lyra tightened her grip around the wand.
Blue mana slowly gathered around her body.
Meanwhile, Ren raised the suppressed Beretta M9 steadily.
His military instincts sharpened instantly.
Boss room.
Unknown enemy.
Confined battlefield.
Possible ambush.
The familiar tension before dangerous combat returned naturally to him.
Then—
The massive stone doors slowly began opening.
