Traveling through to become a B-grade good-for-nothing repairman, Lin Qiu had no talent and only wanted to make money. Accidentally touching a 3S mecha late at night, she unexpectedly awakened resonance power, becoming the sole person who could understand the mecha smart's inner voice. Out-of-control mechas that others avoided like the plague became her most loyal free thugs; materials that others were helpless against were easily pocketed by her. With cold eyes, she watched the Federation's winds and clouds, wanting only to hide in a corner and make a fortune, yet she was forcibly pushed onto the strongest throne by this group of mechas.
