Chapter 3: The First Dungeon
Morning sunlight spilled through the narrow streets of the city. Birds sang as if nothing had ever happened. But for Kang Tae-Hyun, nothing was peaceful.
He had one month. Thirty days to prepare before the world descended into chaos.
Stepping outside, he felt the familiar city air, but everything was different to him now. He knew the future—every betrayal, every monster spawn, every player. And this time… he would not be caught off guard.
Encounter with Yoon Seo-Ah
Kang Tae-Hyun's first stop was the high school courtyard, where the girl he had seen countless times in his past life waited.
Yoon Seo-Ah.
Even ten years younger, she radiated calm intelligence. Her dark hair framed a sharp, observant face.
She looked up from the book she was reading.
"Tae-Hyun?" she asked softly. "You look… different today."
He smirked faintly.
"Just a normal day," he said, his voice steady. But inside, his mind raced.
Seo-Ah was special. Even in the future, she would never betray him. She was his anchor—his only human connection he could trust.
"Are you okay?" she asked, frowning. "You seem… tense."
"I'm fine," he replied. "Just… thinking about training."
Seo-Ah tilted her head. "Training? What do you mean?"
He didn't answer. Not yet. He couldn't reveal everything.
Not until the system has been fully tested.
First Dungeon Appears
That evening, as darkness fell, a tremor shook the city.
Kang Tae-Hyun knew immediately what it was.
The first dungeon… in ten years.
A massive black portal materialized in the middle of a deserted alley. Its surface shimmered with a strange light, pulsating like a heartbeat.
Pedestrians screamed and ran, unaware that monsters would soon spill out.
Kang Tae-Hyun stood calmly, hands in his pockets, eyes narrowed.
Level cap? Not me.
From the portal, a grotesque creature emerged—its body twisted, limbs too long, eyes glowing red.
Dungeon Monster: Flesh Reaper
Level: 50 (normal human limit 100)
It roared, swinging a massive claw. People screamed and scattered.
Kang Tae-Hyun didn't move immediately. He watched its patterns, calculating.
In my previous life, I would've needed a full team to handle this.
He smirked.
Now… I don't.
First Kill
He raised his hand slightly, and the system interface appeared:
[Skill Selection]
He activated Absolute Survival passively, and then created a new skill on the fly.
Skill Name: Infinity Slash
Type: Active, Offensive
Effect: Creates a sword energy wave that ignores defense, scales infinitely with user stats
The monster charged.
Kang Tae-Hyun moved with impossible speed, faster than the eye could follow. His sword appeared in his hand in a flash, and a single swing tore through the monster's body as if it were paper.
Blood sprayed everywhere. The portal flickered. The Flesh Reaper's screams echoed—and then it dissolved into the system's reward points.
EXP Gained: 50,000,000
Skill Points: ∞
Item Dropped: Dungeon Core
Kang Tae-Hyun wiped blood from his blade. Not a single scratch on him.
This is only the beginning.
Aftermath
By morning, news had spread. A single hero had cleared the dungeon alone. Eyewitnesses swore they saw a boy who moved faster than lightning, stronger than a god.
But Kang Tae-Hyun didn't care.
He walked through the streets casually, as if nothing had happened.
One month… thirty days… I'll surpass everyone. And this time…
no one will ever betray me.
A small system notification appeared in his vision:
[Main Quest Updated]
Phase 2: Growth
Objective: Acquire resources and allies
Reward: Power Expansion
He smiled faintly, eyes cold.
Let the world try to stop me…
