The rain fell with an almost violent insistence, as if the sky were trying to wash a city that had been rotten for far too long. Water ran through the filthy streets, dragging along garbage, old blood, and secrets no one wanted to remember. But nothing truly changed, because the filth wasn't in the asphalt or the graffiti-covered walls—it was in the people, in every glance, every deal, every decision made out of necessity or desperation. And that night, though no one knew it yet, the city had decided to reclaim something that belonged to it.
Damián Cruz was running.
It wasn't a graceful or controlled run, but a desperate escape where every step threatened to be his last. His worn-out shoes slipped against the wet pavement, his lungs burned as if he were breathing fire, and his vision blurred at times. Still, he kept moving, pushing his body beyond its limits, because stopping was not an option. Behind him, the footsteps were clear, steady, certain. He didn't need to look back to confirm what he already knew: he was being hunted, and they wouldn't stop until they saw him fall.
It had all started with a simple job—or at least, that's what they told him. A quick delivery, no questions, no complications. Easy money. In another context, he might have hesitated, but in a city where hunger weighs more than fear, you learn to accept without questioning too much. This time, however, he had made a mistake—a small one, almost insignificant, but enough to doom him.
He had opened the package.
He shouldn't have.
He knew it from the beginning, and yet he did it anyway.
Inside, there was no money or drugs, but a strange object—a black device with faint lines that seemed to move beneath its surface, as if it were breathing or pulsing with a life of its own. The moment his fingers touched it, a cold sensation ran through his body—not like a simple chill, but as if something invisible had passed through him, as if the city itself had noticed him at that instant. It lasted only a second, but it left a mark that now, as he ran for his life, he couldn't ignore.
A shout broke through the sound of the rain behind him, confirming the inevitable.
They had caught up.
He turned into a narrow alley, searching for an exit, but the wet ground betrayed him. His foot slipped just enough to break his rhythm. It was a minimal failure, almost imperceptible, but in that world, mistakes weren't measured by size—they were measured by consequences. A hand grabbed him violently and slammed him against the wall with such force that the air left his lungs in an instant, leaving him temporarily unable to react. His vision slowly stabilized, and then he saw them—three figures surrounding him with the calm of those who had done this far too many times to feel anything about it.
One of them stepped forward, watching him with a mix of disinterest and absolute certainty. His voice came out low, heavy, as if he already knew how the scene would end.
*"Did you really think you could escape after opening something that wasn't yours?"*
Damián tried to respond, but all he managed was to spit blood as he weakly shook his head, muttering, *"I didn't know what it was…"* Even he could hear how hollow it sounded. The man watched him for a few seconds before letting out a humorless chuckle and replying with unsettling calm that, in this city, ignorance protected no one—it only made them die faster.
The gun was raised.
Time broke.
The shot came.
And everything disappeared.
Darkness.
Silence.
Nothing.
…
Until something began.
A pulse.
An artificial heartbeat that came from nowhere and everywhere at once, expanding within that absolute void as information began to form with impossible clarity, as if it had always existed.
[Detecting biological signal…]
[Synchronization in progress…]
[Compatibility: 97%]
[Critical condition… correcting…]
This was not a thought.
Not imagination.
It was something external… operating on him.
A system.
Not just any system, but a structure designed to observe, measure, and modify individuals within hostile environments, as if the entire city were an active experiment—and he had just become a variable within that calculation.
[User selected]
[Activating core…]
His eyes snapped open.
Air rushed back into his lungs violently as his body jerked upright on instinct, coughing, gasping, trying to understand why he was still alive. His hand shot to his chest, expecting to find the wound, the blood, any trace of the gunshot—but there was nothing.
Nothing.
The alley was still there.
The rain was still falling.
But the men… were gone.
And in front of him…
It appeared.
An interface floating in the air—translucent, blue, impossible, yet completely real.
[URBAN CODE v1.0 INITIALIZED]
[THE UNDERWORLD SYSTEM ACTIVE]
Damián took a step back, slowly shaking his head, feeling his mind trying to reject what he was seeing as his lips barely moved in a disbelieving whisper.
*"This isn't real…"*
But the more he stared, the clearer it became.
It wasn't an illusion.
It wasn't ordinary technology.
It wasn't external.
The system wasn't in front of him.
It was inside him.
[User: Damián Cruz]
[Status: REBOOTED]
[Condition: CLAIMED BY THE CITY]
That last line lingered in his mind as something more than information, as if it carried a truth he didn't fully understand yet.
He hadn't come back by chance.
He had been chosen.
[Generating initial mission…]
A new notification appeared, clearer, more direct.
[MISSION: SURVIVE]
[Description: The city eliminated you once. It won't fail again.]
[Objective: Stay alive for 24 hours]
[Reward: Core Unlock]
[Failure: Permanent death]
Damián let out a low, dry laugh devoid of humor as his eyes scanned every line, feeling something inside him begin to change.
*Of course… survive…* he thought, almost with irony, as if the city itself were mocking him.
His stats appeared next, as if the system wanted to make it clear exactly where he stood. But this time, they weren't just empty numbers—they were values paired with precise meaning.
[STR: 4 — Physical strength, determines damage and impact capacity]
[REF: 5 — Reflexes, reaction speed and combat coordination]
[END: 3 — Endurance, physical stamina and damage tolerance]
[INF: 1 — Influence, social control, intimidation, and dominance over others]
[INS: 6 — Instinct, danger perception and environmental awareness]
Damián read each line slowly, feeling how every word fit what he had always been, as if the system wasn't just measuring him—it was exposing him without filters.
*I'm trash…* he muttered to himself.
But the system didn't respond with words.
It responded with change.
[Skill Unlocked: Survival Instinct Lv.1]
[Effect: Detects nearby threats]
And in that moment…
Everything changed.
It wasn't gradual.
It wasn't gentle.
It was immediate.
His body tensed without apparent reason, his senses sharpened, and a brutal sensation cut through his mind with absolute clarity.
[Danger detected]
He turned his head toward the darkness of the alley, but at first, he saw nothing.
It didn't matter.
He knew.
He slowly lifted his gaze toward the buildings.
And then he saw it.
A figure on the edge of a rooftop.
Motionless.
Watching him.
[Warning: Hostile zone]
[Probability of death: 87%]
The old Damián would have run, would have panicked, would have accepted his fate without fighting.
But that Damián…
Was already dead.
He slowly clenched his fists as his breathing steadied and his gaze hardened, locking onto the figure as if he were no longer prey, but something beginning to understand the rules of the game.
Because that's what it was.
A game.
Not a fair one.
Not a human one.
One where the city decided who lived… and who evolved.
He didn't need to say it out loud.
The decision had already been made.
*This time… I won't die.*
The system reacted immediately, as if it had been waiting for that moment from the very beginning.
[Trait Unlocked: SURVIVOR]
[Effect: Temporary stat boost under extreme danger]
Above, the figure moved slightly.
As if it had noticed the change.
As if it understood…
That something had awakened.
Because the city hadn't just claimed Damián Cruz that night.
It had activated something within him.
Something designed to grow.
To adapt.
To dominate.
And as the rain continued to fall, covering everything beneath its steady rhythm, the hunt began once again.
But this time…
the prey could see the system.
And in that system…
only those who evolve survive.
