Qin Rui was abandoned by his biological parents in his childhood, solely to reserve a factory recruitment quota for his eldest son. A kind great-aunt took him in and raised him with difficulty. When the great-aunt fell seriously ill and urgently needed medical fees, Qin Rui worked in the fields by day to earn work points and went to the city at night to raise money using his electromechanical skills, only to be misunderstood by the villagers. Later, with his exceptional technical skills, he was specially recruited by a state-owned factory and reunited with the biological family that abandoned him. Qin Rui used his strength to break their contempt, seized the opportunities of the times to overcome foreign technological monopolies, grew all the way, and came to manage the state-owned factory.
