Chen Hao, who graduated from a third-rate college, went south to work with 200 yuan in his pocket. He thought that entering a factory with food and accommodation would be the pinnacle of his life, but he accidentally activated the "strongest screw-driving system" - others tightened screws and he gained experience, others worked overtime and fished, and others were scolded by the line leader and reported to the labor arbitration. While all the workers were struggling for a monthly salary of 5,000 yuan, Chen Hao relied on system rewards to quietly build his own business empire on the assembly line.
