Adrian Voss was a forgotten beta tester—erased by a corrupt game company that put profit over players.Now reborn in Primordial Abyss with a glitched class that lets him control dungeon bosses, he doesn’t grind levels… he grinds players.Every monster he subjugates becomes a weapon. Every raid boss he enslaves earns him passive income. And every overconfident guild that steps into his domain?They drop loot when they die.But this isn't just another OP power trip. Adrian doesn't win because he's stronger—he wins because he's smarter. He lays traps like a raid leader, exploits mechanics like a dev, and rewrites the system from the shadows.From dungeons to PvP, he turns the most advanced gaming system ever built into a weapon that stabs its creators in the back.Now the streamer assassins, sponsored guilds, and even the developers are hunting for the one they call...The Dungeon Phantom.Too bad they don’t realize:The real dungeon isn’t the game.It’s the one they’re walking into.Let the hunt begin.

My method in getting stronger is very simple—eating.I just need to eat artifacts.I've regressed, so I'll be able to eat as much as I want now, right?
