Office worker Lin Yi casually selected the villain's fun-to-play mode in an arcade, changing the three protagonists into a critically ill trapped person, a piece of scrap metal, and a silly dog that loves to pick up trash. The next second, the game wall turned on him, throwing him into Tianheng Star more than a thousand years later, becoming a scrap-level mecha with no identity, no skills, and only 12 hours of lifespan left—his name was precisely the one he had just written down (Yao Heng). His only companion is that source beast Tang Tang whom he personally turned into a silly dog. Starting from the scrap circle, they are hunted by inspection robots, swept into the outer boundary by a magnetic suspension storm, gain charging and resonance through a heavenly thunder accident, and get acquainted with Mu En, an old scoundrel who has barely survived for two hundred years.
