My Time Gate to the Modern World in the 1970s

After Yu Tang failed her college entrance exams, she saw a novel in a dream. In it, a classmate stole her place at university, a fake heiress took over her life and stole her highly educated birth parents, and a scumbag and his family tricked her into marriage. In the end, she died after suffering domestic abuse.

When she woke, she heard a voice say, "Auntie, as long as you agree to let your daughter marry into our family, I'll swallow my pride and go to the city to see my relatives. I'll make sure Xiao Tang gets a permanent job at the meat processing plant."

She looked at her younger brother in alarm. He said happily, "Sis, the Gao family has come to ask for your hand in marriage!"

The Gao family was the scumbag's family in the novel. So everything in the novel was true?

Yu Tang: Luckily, I still have the golden finger of a space-time portal! The marriage swindler, the classmate who stole my identity, the fake heiress who stole my life: I'll send every last one of them to prison.

In the novel, Yu Tang gave up on retaking the exams because her family was poor. But with a space-time portal, Yu Tang wasn't worried about the "steep" costs of tuition, living expenses, travel, and everything else.

Modern study materials: 2 yuan a bundle.

Modern flashlights: 4 yuan each.

Modern jeans: 10 yuan a pair.

Modern scarves, red dresses, digital watches, sunglasses...

And modern industrial technology, business ideas...

With all the resources of modern society at her fingertips, Yu Tang not only saved enough for exam preparation and university, but even had enough to start a business.

Yu Fei had known since childhood that she was a fake heiress. But so what? The real heiress had long ago been dumped in some unknown village. Even after growing up, how could a country bumpkin ever find her way back?

That is, until the day of university registration, when Yu Fei saw a girl who looked just like her mother...

Yu Fei was arrogant and thought herself exceptional, yet she couldn't beat the country bumpkin in her eyes.

She watched helplessly as Yu Tang became a campus celebrity, a famous alumna, a reform pioneer, and a successful entrepreneur... Yu Fei had to scheme and struggle for admiration and favor, while Yu Tang won them effortlessly. Even the most dazzling man of all doted on her.

She completely lost her mind!

Yu Tang: Great, now we can settle the score and bundle you off to prison.

(The heroine has a designated love interest, who appears a little later.)

Theme: Knowledge changes your fate.
