Kicking open the iron door of the Black Heart Machinery Factory, Lin Yuan threw his work badge stained with engine oil on the manager's face: "I quit!" The whole factory was in an uproar - this waste maintenance engineer who had been useless for three years dared to contradict the manager? No one knew that the damaged mysterious mecha in his consciousness was making a roar as his emotions fluctuated violently. The manager sneered and threw out an invitation to the Wasteland Mecha Competition: "Want to leave? I'll tell you if you win." Lin Yuan took the invitation and turned towards the shabbiest workshop on the corner, where there were piles of junk parts that others didn't want. Three days later, a mecha covered in blue fire and pieced together with dozens of scrapped armor modifications stood up from the workshop. The moment this "waste" appeared on the ring, the energy cores of all the high-end mechas in the city began to tremble out of control - as if in fear, but also in worship. There was dead silence in the audience, and a girl in a white dress quietly pressed the record button.
