Apocalypse Scavenger: I Build a Steel Flood from Trash

【Apocalypse + Wasteland + Overpowered Everything + Base Building + Mecha】 The apocalypse arrives, order collapses, and on the wasteland, might makes right! Ye Fan, a so-called "loser" banished to a waste-processing plant, accidentally activates the "Everything Goes Beyond Specs App"! "Ding! Scanned a discarded soda can. Available attributes: 【Superalloy Shell】, 【Energy Core】, 【Autonomous Combat】!" The next second, a fist-sized can transforms into a miniature steel mech and sweeps through a horde of mutant rats! "Ding! Scanned a worn-out tire. Available attributes: 【Infinite Range】, 【All-Terrain Adaptability】, 【Armed Vehicle】!" In an instant, a beat-up tire turns into a heavy tank that crushes zombies! While other survivors are still fighting over a piece of bread, Ye Fan's junkyard has already become a mechanical factory. Discarded computers become intelligent AI butlers, rusty screws evolve into self-destructing homing missiles, and he builds an impregnable steel fortress from piles of trash! "What? You want to know where this steel army came from?" "Oh, I just picked up all this junk and tinkered with it a little!" The apocalypse? Around here, even trash can defy the heavens!
