I! the Goddess of Scientific Research Is Repairing the Tractor at 50

Qu Lingyi, a female college student in modern mechanical engineering, wears the body of a capitalist lady in 1957 and unlocks the golden finger of space. She fought back against her scumbag step-sister, emptied her ancestral property, and donated the factory to the country for free. Then she followed her husband and used her spatial golden fingers and the knowledge she learned in her previous life to become a scientific research power in this era when everything was waiting for development.
