Eighties Sweetheart: The Daring Research Prodigy

(I only started writing this recently, so the rating is low for now, but it'll go up later. Please feel free to leave lots of suggestions and reviews!) Top scientist Shen Qinglan is reborn before the 1984 college entrance exams. Her stepmother poisons her, her best friend plots against her, and a scumbag has his eye on her. In her previous life, she died a tragic death at the hands of all three. This time, she fights back with ruthless determination: she becomes the province's top scorer and enters Tsinghua University, personally sends her stepmother to prison, ruins her best friend's reputation, and puts the scumbag behind bars.

At Tsinghua, she falls in love with the genius Gu Huaian. While studying in the United States, she amasses a vast fortune. After returning to China, she conquers critical technologies that had long been held back, becoming a goddess of scientific research and an empress of the business world. Her daughter, Gu Xingchen, has an extraordinary IQ and inherits a trillion-yuan business empire.

In the end, Shen Qinglan tramples all her enemies beneath her feet and retires in triumph with her beloved, writing an era-defining legend of a woman defying fate and changing her life.
