Global Class Change: I Chose Death Knight and Became the Lich King

The world mutates, games spill into reality, monsters run rampant, and demonic disasters spread.

To fight off invading monsters and expand their living space, everyone must choose a class, change jobs, level up like crazy, and grow stronger.

Su Yu seems like an ordinary guy, but on the day he changes jobs, he gets a System from the start and awakens an S-rank talent: the ability to change into a Death Knight, a monster from the game.

With the System's help, Su Yu grows ever stronger and eventually becomes the Lich King.

In the end, he leads an army of countless undead, the Scourge, to stand before the Demon King, the final boss.

Watching Su Yu sweep away a whole swath of enemies with a single sword strike, powerful enough to make the surrounding space ripple and shake, the Demon King is left stunned.

Weren't Death Knights supposed to be useless?

How can he command such a huge army of undead?

Are you sure he's a Death Knight?
