The registration process was quieter than Cain expected.
No dramatic speeches.
No ceremonial send-offs.
Just paperwork handled by the academy and a narrow archway inside the Guild annex building where the dungeon entrance shimmered faintly like heat over stone.
Their party stood together.
Four.
Still incomplete.
Rei adjusted the strap on his gauntlet. "Last chance to back out."
Liora didn't even glance at him. "You first."
Aera held her guild card carefully between her fingers. "Emergency teleport only activates outside boss chambers," she reminded softly.
Cain stepped toward the entrance.
The surface of the dungeon gate rippled as he pressed the guild card against the embedded crest.
Light flashed briefly.
Permission granted.
Floor 50.
The air changed the moment they stepped through.
Cooler.
Heavier.
Damp.
The stone corridor ahead curved downward in a slow spiral. Mana hung thick in the atmosphere—not hostile, but dense. Like breathing through water.
Rei rolled his shoulders. "Feels different."
"It is," Liora replied. "The mana is unrefined."
They advanced carefully.
Formation instinctively formed.
Liora front left.
Rei front right.
Cain back left.
Aera center-rear.
They had no fifth.
The first sound came as a wet dragging noise.
A ripple across the stone floor.
Then another.
Three translucent masses slid from the shadows ahead.
Slimes.
Not large.
Not imposing.
But wrong.
Their bodies pulsed faintly with internal light, acid bubbles forming and collapsing within their gelatinous frames.
Rei stepped forward first.
He swung cleanly.
The blade passed through the slime with minimal resistance.
The creature split.
Two smaller slimes dropped to the ground.
"…That's annoying."
"Core," Liora said sharply.
Inside the gelatinous mass, faintly visible, a small darker nucleus pulsed.
Rei adjusted his angle and thrust directly toward the center.
This time, the slime collapsed into liquid and dissipated.
The other two surged forward.
One leapt unexpectedly high.
Aera flinched—
Cain moved.
His foot shifted instinctively, stepping between Aera and the incoming slime. He cut downward, not through the body but directly into the darker center.
The slime burst apart.
The third collided against Liora's blade and hissed as wind mana sliced it cleanly in two before she pierced the core.
Silence returned.
Rei exhaled slowly. "Training constructs don't split."
"They also don't corrode steel," Liora said.
Rei glanced at the edge of his blade.
The surface smoked faintly where slime residue touched it.
Aera stepped forward, palm glowing softly.
"Stabilize," she murmured, not healing, but neutralizing the acidic residue through controlled mana dispersion.
Cain watched the dissolving remains on the ground.
Weak.
But unpredictable.
They advanced deeper.
More slimes appeared.
Five this time.
Movement grew chaotic.
Rei overcommitted once and nearly slipped on residual slime.
Liora's precision kept splitting minimal.
Aera's breathing grew tighter.
The environment wasn't dangerous.
But it was relentless.
By the time the fifth wave fell, sweat lined Rei's brow.
"We've killed… what? Twelve?"
"Fourteen," Cain corrected quietly.
A faint shimmer flickered across his vision.
His status window opened briefly without conscious command.
Level Up
Level 35
The notification disappeared as quickly as it appeared.
Rei blinked moments later.
"You saw that too?"
Cain nodded.
Aera's eyes widened slightly. "So leveling begins after confirmed kills…"
No skill notification followed.
Not yet.
Liora wiped her blade clean against the stone wall.
"Keep moving. Momentum matters."
They reached the floor's midpoint chamber.
More slimes pooled across the ground here, drawn by mana density.
This time, eight surged at once.
Rei stepped forward aggressively.
Liora cast Wind Edge, slicing through two cores instantly.
Cain pivoted, cutting one, then another.
One slime slipped past him.
It lunged toward Aera.
She froze for half a second—
Rei moved fast.
Too fast.
His step nearly stumbled as the slime splashed upward.
Cain felt something shift.
Not thought.
Impulse.
His body moved before his mind did.
His foot struck the stone—
For an instant, his second step landed unnaturally fast.
The distance closed quicker than expected.
His blade pierced the slime core before it could reach Aera.
The world seemed slightly slower.
Then normal again.
The last slime dissolved.
Silence returned.
Rei stared at him.
"…You moved weirdly."
Cain blinked once.
His status window flickered again.
Skill Acquired
Quick Step
Quick Step
— Temporarily accelerates stepping speed beyond normal limit.
— Short burst. Moderate strain.
The window faded.
Cain said nothing.
Aera steadied her breathing.
Liora's gaze sharpened slightly.
"Useful," she said simply.
They cleared the remaining slimes of Floor 50 without further incident.
At the boss chamber door, a heavy stone slab stood before them.
Rei rested his blade over his shoulder. "We can skip."
Liora considered the mana flow around the sealed door.
"Not necessary today."
Cain nodded.
"Exit."
Aera raised her guild card.
Light enveloped them briefly.
The corridor dissolved.
They emerged back inside the Guild annex hall.
The air felt lighter.
Cleaner.
Rei flexed his fingers.
"…That was only Floor 50."
Cain glanced at his guild card.
Level 35.
The first step beyond training.
Small.
But real.
Behind the calm surface of his expression, something quiet stirred.
Growth had begun.
And the dungeon had not even tried yet.
