Global Mutations: How Did I Become a Top Master of Every Element by Playing It Safe?

Apocalypse / Ensemble Cast / Plot-Driven / Pairing Undecided

A global mutation begins, and the System drags all of humanity into an apocalypse game.

Here, everyone is an employee of the System, with their own professional identity.

They must complete work assignments and pass performance reviews to earn supplies and stay alive.

Yuan Meng discovers that she's strange. She has no professional attributes at all, a complete unemployed drifter.

She's a bug, an existence the System will erase.

Yuan Meng carefully disguises her professional identity.

She withstands lightning with her mortal body. Oh, so she's a warrior.

She blinks in to assassinate a high-level mutant. Oh, so she's an assassin.

She uses holy light to stack buffs on her teammates. Oh, so she's a priest.

She chants spells to summon the dead. Oh, so she's a mage.

She tames mutants like they're dogs. Oh, so she's a hunter, too.

Wait, why can she put shields on her teammates as well? She's a guardian, too!

Damn! She's an all-class ability user!

Yuan Meng: An all-class ability user? That can't be right. At heart, I'm just an ordinary unemployed drifter.

Yuan Meng: I'm only pretending to be an all-class powerhouse. What if I accidentally become one for real after lying low?

P.S. The apocalypse is already two years underway from the start, and the heroine has already been quietly building up her strength.
