70s: Transmigrated as the Male Lead's Early Deceased Cannon Fodder Stepsister
Ning Xi unexpectedly died and transmigrated into a period novel she had read. She wasn't the female lead, nor a major supporting character; she was merely a minor cannon fodder described in less than thirty words!
She hadn't even officially appeared, only mentioned as the male lead's early deceased stepsister.
The cannon fodder, now with a new soul, refused to play along! Whoever wants to be cannon fodder can go ahead!
Fortunately, the plot hadn't yet begun. Ning Xi punched her scum stepfather and kicked her biased biological mother.
She sold her job, causing all her stepfather's plans to come to naught, and even sent the scummy step-siblings to Beidahuang to "reunite."
In the original novel, after the male lead retired, he received support from a "golden thigh," went into business, and eventually became the wealthiest man in the city.
Knowing the plot in advance, Ning Xi discovered that this "golden thigh" was actually connected to her. Shouldn't she quickly snatch him?
Ning Xi: Alas, I was forced to go to the countryside.
A few days later: Surprise! I'm back in the city again...
She also secured a job and a golden finger, working, making money, taking college entrance exams, and eventually becoming a research powerhouse, contributing to the country!
Note: The female lead doesn't start with scientific research immediately. She proceeds step-by-step: first working, then taking the college entrance exam, attending university, and then engaging in scientific research.
