The wasteland's only ancient mecha. In 2147, the meteorite mechanical virus raged, mechas went berserk and out of control, and humanity retreated to defend the seven high-walled city-states. With a century of technological fracture, only low-spec mass-produced mechas remained, reserved exclusively for the privileged and powerful, while bottom-layer commoners were forbidden to touch mechas. Lin Ye, a bottom-layer sorter of the Panshi City-State, accidentally awakened an ancient mecha, and with the help of the mechanic Su Wan, staged a counterattack story of fighting against the city-state!
