Global Class Change: I'm a Tech Mage Who Annihilates Calamities!

A world where games have merged with reality.

Some change class to wield dual guns and become wandering gunmen.

Some take up blades, appearing and disappearing without a trace.

Some become werewolves, turning into beasts and fighting to the death!

Su Mu changes class to technologist.

He thought it would be just a civilian profession, but he never expected to create something that combined "technology and ruthless ingenuity"!

He develops countless mechanical battle maidens.

He builds intelligent mechs.

He researches antimatter energy cannons.

He mass-produces laser fighter jets.

Disaster strikes, and demon gods descend.

Looking at the endless ranks of mechs and fighter jets behind Su Mu, the boss falls into deep thought.

"So, which one of us is the calamity?"

Su Mu: "I don't know who's the calamity. I'm a technologist, and I specialize in wiping them out!"
