In the winter of 1962, Lin Feng transmigrates into Love in the Courtyard as a technician.
In an era of scarce supplies, he relies on the System shop in his mind and his knowledge of the future, starting out as a Grade Three fitter at a steel mill.
He refits old Soviet equipment, develops a magnetic grating ruler system, and breaks through technological barriers.
As he faces the warmth and coldness of life in the courtyard, power struggles at the factory, and the many restrictions of the times, he quietly sparks the flame of Chinese industry.
CNC machine tools, precision sensors, adaptive algorithms... one piece of advanced technology after another takes root in this extraordinary era.
From the courtyard to factories across the country, from technician to pioneer of industry.
This is the story of Chinese engineers forging a path to break through.
