I Asked You to Repair Home Appliances, but You Took Out the Aircraft Carrier?

Traveling through the parallel world, Gu Cheng inherited a repair shop that was about to close down in Jiangcheng and activated the [Shen Gong Apocalypse System]. As long as you repair everything, you can get rewards and experience, and unlock heaven-defying technology! Customer: "Boss, can my electric kettle be repaired?" Gu Cheng: "Yes, 10 yuan." Beautiful anchor: "Boss, my Bentley is flooded. Can it be repaired?" Gu Cheng: "Yes, but you have to pay more." Fan: "Anchor, can you repair tanks?" Gu Cheng: "... You can carry it over and talk about it later." Until one day, when a heavy-duty truck painted with the August 1st Army emblem pulled a pile of scrap metal and stopped at the door of the repair shop, the entire network exploded! Military Region Boss: "Master Gu, do you see this scrapped 59D?" Gu Cheng held a cigarette in his mouth with a look of disgust on his face: "Trouble! But militiamen are also soldiers, bring them in!" Later, stealth fighters, nuclear submarines, photolithography machines, and even the legendary national defense formation... When reporters interviewed the world's top national treasure engineer, Gu Cheng blew out a smoke ring, his face full of vicissitudes of life: "I'm really just a repairman, why do you guys ask me to fix everything?"
