Fang Yu accidentally transmigrated to an abandoned mechanical planet, opening his eyes to become a battered robot with a battery health of only two percent, facing the desperate situation of shutting down and dissipating at any time. In this wasteland world piled high with home appliance wrecks, spaceship fragments, and mechanical garbage, he started his difficult survival by dismantling scrap and digging out batteries, accidentally awakening the Devouring Evolution System—devouring metal can accumulate materials, obtain evolution points, and unlock various black technologies layer by layer. Relying on scavenging trash to hand-craft wind turbines, heliostat solar towers, and unlocking nano-swarms, upon the wreckage of the abandoned civilization, he started from scratch to build his own mechanical empire.
