Rebirth in the 80s: The Scholar Wife is Cute

Deceived into marriage, exploited for a lifetime as a nanny without pay, and finally beaten to death by her adoptive mother in front of her adoptive father's sickbed, Shen Mianmian's miserable life came to an end.
When she opened her eyes again, she found herself back at fifteen. Shen Mianmian vowed to escape her past fate, punish her malicious cousin and adoptive mother, but accidentally shone too brightly in the process.
The third-to-last student in school suddenly rose to the top, becoming the candidate fought over by prestigious universities, causing a sensation among all the teachers and students...
While others were busy studying, Shen Mianmian was busy starting small businesses to make money...
While others were preparing for the college entrance exams, Shen Mianmian purchased the two most notorious haunted houses in Beijing in one go... becoming an oddity in everyone's eyes, they mocked her that even if she had the fortune to buy them, she might not have the life to live in them.
While others graduated and were busy looking for jobs, the haunted properties purchased by Shen Mianmian were requisitioned by the government, earning her a considerable amount of demolition compensation.
Those who had mocked her couldn't help but slap themselves twice... inquiring everywhere where there might be haunted houses for sale.
Shen Mianmian, originally needing to borrow money for tuition fees, used the demolition funds and leveraged her rebirth advantage to buy a suitable plot of land and built a rental building, transforming into a Beijing's wealthiest and most prosperous landlady...
One day, Shen Mianmian, carrying a bag of keys and having just collected the rent, was dragged to the Civil Affairs Bureau.
"Shen Mianmian, it's time for you to pay back what you owe me."
