I Asked You to Collect Rags, but I Didn't Ask You to Build Mechas!

Su Bai took over his father's scrap recycling station, which was on the verge of bankruptcy. He originally wanted to collect the junk and repay his debts, but unexpectedly awakened the [Magic Modification System of All Things]. As long as it is trash, through his hands, it can be turned into treasure, and even evolve! Recycle [Scrapped Drone] and magically transform it into ["Black Antelope" Stealth Air and Space Reconnaissance Aircraft]; Recycle [Old Motorcycle] and magically transform it into [Individual Combat Exoskeleton Armor]; Recycle the [rusty gas tank] and magically transform it into a [plasma high-explosive mortar]! … Originally, Su Bai just wanted to hang these "gadgets" on Xianyu and sell them to make some money to support his family. Until that day, a certain country's sixth-generation fighter jet was showing off its power at the border, but was knocked down on the spot by Su Bai's drone used to deliver express delivery... The whole network was shocked! Military bosses surrounded the scrap station overnight! The leader held Su Bai's trembling hand: "Comrade, please stop collecting rags! Come to the national team and be the chief engineer! We want to build a Star Destroyer!" Su Bai looked innocent: "Leader, I'm just a rag collector. This mecha... It's really used to move bricks!"
