The battlefield had become something far beyond a simple trial.
The chamber shook continuously as countless powers collided within its confines. Flames roared across the cavern walls, casting violent shadows over shattered stone and rivers of molten rock. Ash drifted through the air like black snow while heat distorted the space itself.
Every corner of the chamber bore the scars of battle.
Massive craters gouged the floor. Entire sections of the walls had collapsed. Ancient pillars lay broken beneath piles of rubble, and the dungeon itself seemed to groan under the strain of the destruction.
At the center of the devastation stood Rio.
Her breathing remained steady despite everything that had happened.
A thin streak of blood ran down her cheek, disappearing beneath the soot covering parts of her face. Her HP had dropped significantly during the battle and hovered around forty percent, but there was no fear in her eyes.
If anything, she looked more focused than before.
"Good," she said quietly.
A faint smile touched her lips.
"Now it feels real."
The corrupted enemies surrounding her showed no signs of slowing down.
The spear knight moved first.
Despite having both of its hands severed earlier in the battle, the creature remained active. Black energy flowed from the stumps of its wrists, forming phantom limbs that wrapped around the spear and restored its fighting stance.
The weapon rose once more.
The knight lowered itself slightly before launching forward.
Its thrust was even faster than before.
Rio immediately noticed the difference.
The spear bent unnaturally during its attack, altering its trajectory mid-strike. What should have been a straightforward thrust suddenly curved toward her shoulder.
She reacted instantly.
Steel collided with steel.
The clash echoed throughout the chamber.
Rio managed to deflect the attack, but the unusual angle allowed the spearhead to graze her shoulder.
A shallow cut opened.
Her HP dropped slightly.
"Tch."
Before she could recover, the twin-blade knight attacked.
The corrupted warrior emerged from her blind spot with frightening speed.
Two blades slashed horizontally.
Then vertically.
Then upward.
The attacks flowed together without pause, creating a relentless barrage designed to overwhelm even the smallest opening.
Rio's Crimson Bloodmoon moved like an extension of her body.
Clang.
Clang.
Clang.
Clang.
Every strike was intercepted.
Every movement was efficient.
Minimal.
Precise.
Yet even she could tell something was changing.
"They're adapting."
High above the battlefield, the corrupted phoenix struggled against its restraints.
The enormous creature remained pinned to the cavern wall by stone spikes and debris from earlier attacks, but the flames surrounding its body continued to intensify.
Its wings twitched violently.
Every movement melted more of the stone trapping it.
A distorted screech echoed through the chamber.
The creature wasn't defeated yet.
Rio took a single step backward before shifting forward again.
Her eyes moved across the battlefield, analyzing every enemy simultaneously.
The female knight stood farther back with her staff raised.
Dark mana swirled around the weapon's tip.
The spell was already forming.
Rio recognized the threat immediately.
Without hesitation, she burst forward.
The twin-blade knight attempted to intercept her.
Steel clashed briefly.
However, Rio never intended to engage.
She pivoted at the last moment and slipped past the melee fighter entirely.
The female knight's spell reached completion.
Too late.
Rio's saber flashed.
A single crimson arc cut through the air.
The staff split neatly in half.
The caster staggered backward for the first time since the battle began.
Rio immediately followed with another strike.
But the spear knight intervened.
The weapon shot toward her side with lethal precision.
Forced to retreat, she jumped backward and landed lightly several meters away.
The battlefield shifted again.
The corrupted unicorn still stood.
Its body burned beneath the flames consuming it, but the creature refused to fall.
Its horn had been destroyed.
Its body heavily damaged.
Yet power continued gathering around its forehead.
An unstable glow pulsed there.
"Still fighting?"
Rio exhaled slowly.
"Then I'll finish all of you at once."
This time she attacked aggressively.
The spear knight lunged.
She sidestepped.
The twin blades followed.
She parried.
Then counterattacked.
A crimson slash tore across the twin-blade knight's chest.
The creature staggered.
An opening appeared.
Rio immediately exploited it.
She kicked off the ground and surged toward the unicorn.
The creature attempted to react.
It wasn't fast enough.
The Crimson Bloodmoon rose.
Then fell.
A diagonal strike carved across the unicorn's body.
The flames consuming it erupted violently.
Its form flickered and destabilized.
Then everything changed.
A massive shadow spread across the chamber.
Rio looked upward.
Her eyes widened slightly.
The ceiling was collapsing.
Gigantic cracks raced across the stone overhead before the entire structure gave way.
Chunks of rock the size of houses plummeted downward.
Sunlight—or something resembling it—poured into the chamber through the opening above.
Then shapes appeared within that light.
The first dragon crashed through the ceiling.
Its scales gleamed despite the damage covering its body. One wing hung partially broken, but it remained alive and roaring.
It slammed into the battlefield and rolled across the ground.
A second dragon followed.
Then a third.
A fourth.
A fifth.
A sixth.
A seventh.
Each represented a different element.
Fire.
Lightning.
Ice.
Earth.
Wind.
Light.
Shadow.
All of them crashed into the chamber together.
And they weren't alone.
A colossal figure descended behind them.
The techno-centaur.
Its enormous mechanical frame tore through the opening in the ceiling with enough force to shake the entire dungeon.
Its massive blade remained clenched firmly in its hands.
Mechanical legs unfolded mid-fall, stabilizing the giant construct before it landed.
The impact was catastrophic.
The chamber trembled.
Shockwaves blasted across the battlefield.
Debris scattered in every direction.
Rio dug her feet into the ground and slid backward slightly.
Then she saw the final figure falling from above.
A familiar figure.
Ryota.
He spun through the air amidst the collapsing debris, dragons, and falling stone.
And somehow—
he was grinning.
He hit the ground hard.
The impact kicked up a cloud of dust and rubble.
After rolling once, he pushed himself back onto his feet as if falling through an entire dungeon ceiling was merely an inconvenience.
The dust slowly settled.
For a brief moment, everything seemed frozen.
Rio and Ryota looked at each other across the ruined battlefield.
Between them stood dragons, corrupted beasts, undead knights, and a mechanical executioner.
Yet neither seemed particularly surprised.
Ryota scratched the back of his head while looking around.
His gaze swept across the battlefield.
The dragons.
The centaur.
The wounded phoenix pinned against the wall.
The corrupted knights.
Finally, Rio.
"So..." he said.
"Is this yours?"
Rio closed her eyes for a moment.
Not out of frustration.
Not out of annoyance.
Simply acceptance.
When she opened them again, her focus had returned completely.
"No."
She raised the Crimson Bloodmoon.
Crimson light flared across the battlefield.
The dragons growled.
The centaur adjusted its stance.
The surviving monsters prepared themselves.
"But now it is."
The chamber trembled once more.
The trial had changed.
What had begun as two separate paths had become one battlefield.
One impossible challenge.
One final trial.
Two players now stood against every enemy the dungeon could throw at them.
For the first time since entering the World Key, neither Rio nor Ryota stood alone.
And somehow—
that made the situation even more dangerous.
Because the dungeon was no longer testing individuals.
It was testing whether two anomalies, existing far earlier than they ever should have, could truly break the rules of the world itself.
The answer was about to be decided.
And every monster in the chamber intended to stop them.
