All People Are Coming: My Territory Is the Recycling Bin

The world descended into a wasteland, and the territory where I awakened was a garbage recycling station. Others start the barracks in the mage tower, recruit troops, and conquer the dungeon. I started with a broken shovel and could only pick up trash behind others. When everyone laughed at me for being a chosen "garbage man", I silently threw their discarded "waste" into the decomposer. Bite! Decompose the "broken blade that failed to be quenched" and understand the god-level sword skills! [Ding! Decompose the "player death video" and perfectly reproduce the BOSS's ultimate skill! [Ding! Decompose the "scrapped mechanical remains" and reconstruct a mobile war fortress! They fought bloody battles for the pitiful reward after clearing the level. I squatted at the door of the dungeon, waiting for their group to be destroyed, so that I could go in and inherit all their "legacy"! Many years later, the world-ending disaster struck, and the territories of all the strong men were in danger of collapse. I stood on a mobile fortress built with countless magical costumes and artifacts, and helplessly spread my hands: "Don't get me wrong, this magical outfit of mine was really picked up from rubbish."
