1. Fantasy + Game System (LitRPG / Rebirth)
Title: Reincarnated as the Dungeon Core
Premise: A genius gamer dies and wakes up not as a hero, but as the core of a dungeon in a fantasy world. He must build traps, recruit monsters, and evolve the dungeon while fending off adventurers. But something's off—he's gaining human emotions... and memories from a past life that aren't his
Expanded Premise:
A top-tier player known for dominating strategy RPGs dies mysteriously during a livestream. He wakes up in another world—not as a hero, but as the core of a low-level dungeon. To survive, he must grow the dungeon, create monsters, set traps, and defeat invading adventurers.
But things take a turn when he realizes he can gain skills and evolve like a player character—and his dungeon isn't just a structure… it's tied to a goddess of chaos who might be manipulating everything.

Goal: Introduce the MC, his death, and rebirth as a Dungeon Core.

Chat explodes with praise—but then power surges. He blacks out and dies.

Can hear distant sounds: footsteps, adventurers approaching.
Tutorial screen appears in his mind: Welcome to Dungeon Core Mode. Survive.

Ends with: "This… this might be fun."
Here's Chapter 1: "Game Over" of Reincarnated as the Dungeon Core, based on the outline:
Chapter 1: Game Over
The boss fell.
Finally.
Thousands watching the stream cheered in the chat.
Kai leaned back in his chair, sweat cooling on his brow. "And that, ladies and gentlemen, is how you solo a level 99 nightmare dungeon with no armor."
He raised a fist to the webcam with a grin—then everything went black.
The screen.
His lights.
His world.
A sharp crack echoed, like shattering glass in his skull. Something snapped.
Kai never saw the streaming chat flood with confusion.
He never read the flood of "Is he okay?"
Because Kai… had already died.
Darkness.
A soft hum.
The feeling of floating, bodiless.
> [SYSTEM: Consciousness preserved. Compatibility: 87.4%]
[Initializing Soul Binding Protocol…]
Kai blinked—but he had no eyes.
No hands. No voice.
"Wh… what?" The words echoed inside him.
> [Welcome, new Dungeon Core.]
[Designation: Unknown Entity. Tier: F-Rank.]
[Objective: Survive.]
A light flickered.
He wasn't in a room. He was the room—or at least, something at the center of it.
He could feel stone walls, dripping water, and cool air moving through tunnels.
"What the hell is this? A dream? VR?"
Another message blinked into his mind:
> [You have summoned a Level 1 Slime. -1 Dungeon Point]
[You have 4 Dungeon Points remaining.]
A pale blue slime plopped into existence beside him, jiggling like a gelatinous idiot.
Then—footsteps.
Real, booted footsteps.
A group of four adventurers, young and cocky, stepped into his domain with torches. "Slime cave, huh?" one laughed. "Let's clean up and grab the core."
Something inside Kai stirred.
Instinct? Rage?
No. Strategy.
He focused. Spike trap, 3 DP. Deploy.
Slime, lure them in.
The slime bounced forward eagerly.
"What the—?"
THUNK.
Spikes erupted from the floor, impaling two of them. The others screamed.
> [You have defeated: Human Adventurer x2. +6 Dungeon Points]
A thrill surged through him. Not joy.
Satisfaction.
Control.
The remaining two fled, leaving behind packs, weapons, and blood.
> [Level Up Available.]
Kai laughed—or would have, if he had a mouth.
"This… this isn't a dream."
A glowing UI flickered across his mental vision:
> [Welcome to Dungeon Core Mode. You are the boss now.]
And for the first time in his life—or afterlife—Kai didn't want to win the game.
He wanted to break it.
