At 11:59 PM, the world was normal.
At 12:00 AM, humanity's era ended.
Kael was lying on his bed, half-focused on his phone while rain quietly fell outside his apartment.
The city was still awake.
Cars moved along the streets.
Buildings glowed with countless lights.
People laughed somewhere below.
It was an ordinary night.
Until every light in the city went out.
Kael sat up.
"What?"
His phone lost its signal.
Then the screen went completely black.
For three seconds, nothing happened.
A strange white message suddenly appeared.
[THE EVOLUTIONARY ERA HAS BEGUN.]
Kael stared at it.
Another line appeared.
[THE PREVIOUS ERA HAS ENDED.]
His eyebrows tightened.
Then—
[ALL LIVING ORGANISMS ARE NOW SUBJECT TO EVOLUTIONARY PRESSURE.]
Kael slowly stood.
"What does that mean?"
The answer came immediately.
[SURVIVAL IS NO LONGER GUARANTEED.]
The message disappeared.
Kael walked toward the window.
The entire city had gone dark.
People were coming out of buildings.
Some were using their phone flashlights.
Others were shouting.
Then Kael noticed something strange.
The stars were disappearing.
One after another.
Not being covered by clouds.
Simply disappearing.
Kael's breathing stopped.
Something enormous moved across the night sky.
He couldn't see its shape.
He could only see a massive shadow passing between the clouds.
Then—
BOOM!
An explosion erupted several streets away.
Another followed.
BOOM!
Then another.
The city descended into chaos.
Car alarms began screaming.
People ran through the streets.
Kael grabbed his backpack.
He had no idea what was happening, but every instinct told him to leave.
He opened the apartment door.
A strange sound came from the hallway.
Scratch.
Kael froze.
Another sound.
Scratch... scratch.
Something was moving outside.
He slowly picked up the metal rod he kept beside the door.
The scratching stopped.
Silence.
Kael held his breath.
Then the door shook violently.
BANG!
He jumped backward.
Another impact.
The wooden door cracked.
Kael tightened his grip.
"Come on..."
BANG!
The door broke open.
Something entered.
Kael's mind went blank.
It looked like a wolf.
But it was far too large.
Its body was covered in dark, hardened skin.
Its limbs were unnaturally long.
Its eyes glowed faintly in the darkness.
Kael took one step backward.
The creature growled.
Then it attacked.
Kael swung the metal rod.
THUD!
The rod struck its side.
The creature barely moved.
Kael's eyes widened.
It lunged.
He jumped aside.
Its claws struck the wall.
CRACK!
Kael stumbled backward.
He couldn't fight this thing.
It was too strong.
The creature turned toward him.
Kael looked around desperately.
His eyes landed on the kitchen.
The stove.
An idea appeared in his mind.
He ran.
The creature chased him.
Kael grabbed the lighter and turned on the gas.
The creature leaped.
Kael threw himself sideways.
He ignited the stove.
A burst of flame forced the creature back.
It recoiled.
Kael didn't waste the opportunity.
He grabbed the metal rod with both hands and struck.
Once.
Twice.
Again.
The creature finally collapsed.
Kael stood completely still.
His chest rose and fell rapidly.
His hands were shaking.
He had survived.
Barely.
Then something appeared before his eyes.
Not on his phone.
In the air.
A translucent blue screen.
Kael stared at it.
[TARGET DEFEATED.]
[Analyzing evolutionary pressure...]
[Analysis complete.]
[You have survived a lifeform beyond your current biological limits.]
Kael's eyes widened.
Another notification appeared.
[Unique Evolutionary Trait detected.]
[Adaptive Evolution acquired.]
A second screen opened.

Kael stared at the screen.
"What... is this?"
Another notification appeared.

Kael slowly clenched his fist.
He felt different.
Not stronger.
Not dramatically.
Just... different.
His breathing had already recovered.
The pain in his muscles was fading.
His vision seemed slightly clearer in the darkness.
Kael looked at the creature.
Then at the status screen.
"So I evolve by surviving."
The screen remained silent.
Kael looked toward the window.
The city outside was burning.
Strange creatures were moving through the streets.
Trees were growing across roads that had been clear only minutes ago.
Something was changing in the distance.
Something enormous.
Kael swallowed.
The world had not simply been destroyed.
It had been transformed.
And he had been given one ability.
Adaptive Evolution.
But there was something that frightened him more than the monsters.
His evolution progress was only—
0.01%.
Kael looked at the number for a long moment.
Then he understood.
If reaching the next stage required 100%...
he had a very long way to go.
And the world wasn't going to wait for him.
Outside, another roar shook the city.
Kael picked up his metal rod.
He looked at the darkness beyond his apartment.
His fear remained.
But beneath it was something else.
Determination.
"If the world is going to evolve..."
Kael tightened his grip.
"Then so will I."
And that night, humanity's struggle for survival began.
