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.

In novels with a stud there is always a Senior Martial Brother like this:

In the early stages of the novel, his innate talent is high, his cultivation is good, his appearance is handsome, and he has an intelligent, cute younger Martial Sister as a fiancée.

In the middle stages of the novel, he is caught unprepared and defeated by a young disciple (the protagonist) in the sect who’s hardly remarkable at all. From then on, he falls from his godly altar and loses his brilliance. Even his young Martial Sister leaves him for someone else.

In the late stages of the novel, he continues to turn dark, going down the Demonic Path and becoming the major villainous boss. However, the protagonist still ruthlessly defeats him and his soul is eternally sealed.

Once Qin Mo opened his eyes, he discovered that he had become this Senior Martial Brother.
