I Upgraded an Alien Battleship

In the age of interstellar colonization, Lin Yuanfan is a low-ranking maintenance worker. One day, he accidentally stumbles into a crashed alien spacecraft. From the moment he comes into contact with its core, the "Mechanical Ascension System" completely rewrites the course of his life. The unrepairable spacecraft gives Lin Yuanfan the ability to analyze, dismantle, and recreate any mechanical creation. From an obsolete mech that nobody cares about to a "Scavenger" capable of punching through alloy armor. From an astonishingly efficient power cell to an interstellar power core capable of upending humanity's energy landscape. When colossal beings in the sea of stars turn their gaze toward Earth, and everyone thinks the apocalypse has arrived, Lin Yuanfan pilots the "alien warship" he modified himself and slowly rises from the planet's shadow. "Sorry, but this ship is a Lin now."
