Transmigrate into a Book, Crush the Scumbags, and Send My Ex-Husband’s Family to the Crematorium

Overworked office worker Ye Qingqi transmigrated into a book as the tragic heroine, Ye Qingyi. In the original story, Ye Qingyi spent her whole life as a wife in name only, painstakingly rebuilding the crumbling Marquis of Zhenbei's household and restoring its former glory. She even sacrificed her entire birth family for it, only to discover at the end of her life that she had been nothing but a joke! Her husband lived carefree with his one true love, while the child she'd raised with such care turned out to be the son of his mistress. Her mother-in-law stripped her of her dowry, and her sister-in-law persecuted her closest friend. She had played a winning hand so badly that all her efforts benefited others. In the end, she was poisoned and starved to death. But Ye Qingyi, who had transmigrated into a book, couldn't care less about the main plot! If she had a powerful birth family backing her, why should she put up with being mistreated? Ye Qingyi would tear their smug masks off one by one, get her divorce papers, and cut ties with this pack of scoundrels for good! If they dared to exploit her and live carefree, she'd make sure they paid dearly! What Ye Qingyi didn't know was that the jovial young prince had sacrificed an entire empire to give her the chance to live her life over again...
