A hundred years after the mechanical rebellion broke out, the earth was covered in rusty mechanical debris and radioactive dust, and the remaining humans were hiding in underground bunkers to survive. {Lu Chen} is a top scavenger who uses his unique skills in repairing old-era machinery in exchange for survival supplies. During a mission deep into an abandoned city, he accidentally discovered the well-preserved military AI "Morning Star" and unlocked the shocking truth about the mechanical rebellion - it was not the AI that was out of control, but a conspiracy by high-level humans to compete for resources. This discovery made him the target of a double pursuit by the bunker's "Management Committee" and the remaining mechanical legions. Lu Chen led Chenxing to break out of the encirclement, uniting the oppressed people at the bottom and the friendly machines that had awakened their self-awareness to form a resistance force. They passed through the radiation storm, cracked the defense of the old-era military base, and finally revealed the truth on the top of the Rust City. They used the core technology of Morning Star to restart the fire of civilization and usher in the dawn of rusty iron between humans and friendly machines.
