Time travels back to 1959, and I am the most humble apprentice in the whole factory. But when faced with a top-secret machine tool that even an eighth-level fitter couldn't handle, I was able to dismantle it with my bare hands and repair it perfectly! Just because after time travel, I awakened the super engineer system, which allows me to rub aircraft carrier cannons and build high-precision equipment at will in this era! However, I do not covet glory and wealth, but with my magical skills and the most important weapon of the country, I just want to break the Western technological blockade, step by step from a humble boy, to counterattack and become a military industry master respected by the whole country!
