Global Class Change: Builder Is Weak? Iron Man from the Start

Su Cheng transmigrates to a parallel world where games and reality have merged, monsters and alien races run rampant, and countless dungeons and secret realms exist.

At eighteen, people can change class and become professionals, able to fight back against monsters.

At his class-change ceremony, Su Cheng becomes an all-purpose builder, a notoriously awful class with a great many restrictions. Just as he is at a loss, he binds the strongest Builder System. It contains countless blueprints and materials from other worlds, which he can obtain by completing System missions.

The restrictions are completely removed.

He gets a beginner's gift pack from the start, containing the blueprints and all the materials for an Iron Man suit.

After that, drones, mushroom bombs, anti-Hulk armor, Bumblebee, mobile fortresses, sky cities… are created one after another.

One day, the Abyss opens, and countless gods and demons descend. They see Su Cheng's rock-solid fortress and its innumerable powerful guards, immediately stop in their tracks, and turn to run back. "Brothers, this one's too tough! Retreat!"

Su Cheng gives a cold smile. "You think you can run? Not a chance."

"Kill them!"
