All My Scrap Is Mythic-Grade, and the Nation Takes Me Leveling Up

The era of universal class changes began, and Su Bai was assigned the profession everyone agreed was the most useless: “Useless Maker”! Everything he makes is 100% useless? He came with a “good-for-nothing” label right from the start. The school shook its head. Everyone thought he was a loser. But when Su Bai pulled out his first creation, the whole world's tune changed! You ask him to make a power bank, and he charges up several million kilowatt-hours, fires a bolt of ball lightning, and blasts a Hell-level altar flat? You ask him to make ink, and he exploits an eightfold reward System bug, single-handedly boosts Handong Province's GDP, and makes dungeon drop rates twelve times higher? You ask him to make a portable air conditioner... and the Antarctic Island restricted zone falls to the world, the national team is wiped out, yet he walks in wearing a T-shirt and freezes the boss to pieces? Cool, aloof campus beauty: “I promised I'd protect him, but now he casually makes a power bank and I feel like it could kill a god!” Provincial bureau big shot: “Even if Su Bai makes a toilet, I'm listing it as a strategic resource! Anyone who touches him is threatening the lifeline of Handong Province!” Dragon Kingdom leadership: “Please, Su Bai, even if you make a mousetrap, you have to sell it to the country! Name your price!” Su Bai: “I'm really getting a raw deal here. I'm just an honest Maker. The things I make... really are ‘useless’!”
