Global Class Change: They Say Mechanics Are Weak? I Guard the World

The world mutates, and games descend into reality. Monsters run rampant, and dungeons and secret realms are everywhere.

To fight off monster attacks, everyone must choose a profession, level up, and grow stronger.

On the day he awakened, Lin Yu became the world's only Mechanist. Mechanists are incredibly powerful, said to be capable of fielding an entire army on their own.

But to build a host of combat machines, a Mechanist needs all kinds of blueprints.

The problem is that almost no usable blueprints exist anywhere in the world! Without them, a Mechanist is worthless!

Fortunately, Lin Yu awakened the Mechanical Overlord System! As his level rises, he can obtain all kinds of blueprints.

Laser guns, full suits of mechanical armor, combat automatons, automated cannons: one powerful machine after another takes shape in his hands.

When monsters besiege the city and a mechanical tyrannosaurus dozens of meters tall stands like a god of war before the walls, everyone cheers his name.
