Siheyuan: Return a Hundred Times and Send the Country an Atomic Bomb

Lin Feng traveled through a courtyard house in the 1960s and awakened to the hundred-fold return system of the steel rolling mill. Whatever is made in the rolling mill is returned a hundredfold. Maybe there was an accident during time travel, and Lin Feng didn't know that he had a system. Until one day, Lin Feng's ability was discovered by the country. "Damn it, if you have this ability, you just drive screws? Hurry up and upgrade Lin Feng to level eight fitter!" Next moment: atomic bomb, precision machine tools, manned space rocket, photolithography machine... No matter how sophisticated the items were, the country moved them to the Red Star Rolling Mill for production. Lin Feng's various unreasonable demands were met by the state. … All the birds in the courtyard were confused. Master: Why did Lin Feng upgrade to level 8 fitter before me? Second uncle: My official power is not as big as Lin Feng's toes! Third Uncle: I plotted against Lin Feng, but ended up plotting against myself and ended up in jail? Silly Zhu: Why did the factory director let me run a small stove for Lin Feng alone? Qin Huairu: If I had known earlier, I would have seduced Lin Feng!
