Scrap Metal Sorcery: A System Apocalypse LitRPG (Junkmancer Book 1)

The System arrived. Humanity fell. Oscar just wanted to build a better toaster. When the Galactic Integration transformed Earth into a ruthless tutorial zone for the wider universe, billions perished. Monsters roam the ruined streets of Seattle, and the survivors are busy forming guilds, claiming combat classes, and fighting over mana crystals. Oscar didn’t get a combat class. Thanks to his obsession with fixing broken electronics when the System dropped, he was assigned the lowest-tier crafting class available: Junkmancer. Armed with a rusty wrench, a sarcastic System interface, and the ability to extract magical properties from literal garbage, Oscar is forced to survive in a world that wants him dead. But as the monsters get stronger and a tyrannical warlord sets his sights on Oscar’s neighborhood, he’s about to prove that one man’s trash is another man’s weapon of mass destruction. He’ll need to level up, scavenge the apocalypse, and build a sanctuary. Because the second wave of the Integration is coming, and a rusty wrench isn't going to cut it.
