Under the wave of Industry 4.0, Foreign investment technology is blocked, and domestic heavy industry is struggling. Li Tiezhu, a low-level maintenance worker with only a vocational school education, possesses astonishing mechanical talent and hacking skills. When the returning elite was helpless about the failure of the imported equipment, he disassembled and reprogrammed the core algorithm with his bare hands, allowing the paralyzed 10,000-ton press to roar back to life. From the ridiculed "bitch repairman" to the "national treasure-level master" who is begged by domestic and foreign giants, he uses the most hard-core technology to break monopolies time and time again and slap in the face the so-called elites who are superstitious about foreign diplomas. This is not a simple counterattack, this is a contest about the backbone of a big country - with a pair of oily hands, he has forcibly opened a broad road to intelligent manufacturing for China Heavy Industries.
