My Car Repair Shop Only Accepts Orders from Gods and Demons

Traveling through the parallel city, Su Chen inherited a repair shop that was about to close down, and was also dragged to participate in the "National Professional Top" live broadcast competition. While other players were still showing off their mechas and genetic pets, Su Chen's live broadcast room said: "Boss, the drone chip is burned out." Su Chen casually took out the crystal from the scrap box, swiped it on the photolithography machine for ten seconds, and a brand new chip with twice the performance was born. "Boss, the gaming helmet has high latency." Su Chen pressed his finger a few times to optimize the transmission path at the physical level and reduce the delay by 5 milliseconds, which shocked the entire network. Until one day, the empire's top-secret "Pioneer" broke down, and the country's most important weapon was about to be scrapped. A cold and beautiful female scientist came to the door. The whole network was shocked that he actually repaired the country's most important weapon in five minutes in front of hundreds of millions of viewers, and even improved its performance by 30%! Military boss: "He is not a repairman, he is our only hope!" Goddess of Scientific Research: "His knowledge surpasses our entire era." When the alien fleet came to the city and human civilization was in danger, Su Chen silently lit a cigarette, and behind him, a Star Destroyer that could penetrate the galaxy slowly rose into the sky. "Don't get me wrong, I'm really just a repairman."
