When she woke up, Su Yan, a national treasure engineer, became a little orphan girl in the 1960s, with a sickly and handsome man as her husband.
Facing the eager relatives and family disciples, Su Yan rolled up her sleeves: Don't be afraid, I have the space and skills!
She improves farm machinery and develops new materials, but every step she takes is on the edge of danger. Technology was stolen, achievements were tainted, and she was even labeled as a collaborator... Amidst the many crises, the frail husband who had been protecting her always quietly took action to pull her out of desperate situations.

Let's see how the husband and wife work together to create the most solid backing for the country's rise in the turbulent years!
