After Being Possessed, I Became Everyone’s Favorite?!

My name is Xu Youwei, the eldest legitimate daughter of the Yong'an Marquis's household in the Great Qian dynasty. My mother is dead, my father doesn't care about me, my half-sister bullies me, and the servants look down on me. I've lived for seventeen years, and even a dog has had a better life. Then one day, a modern office worker named Lin Wan suddenly died and transmigrated into my body. She thought my household-intrigue tactics were way too lame, so she decided to take matters into her own hands. In three days, she ruined my scheming half-sister's reputation and uncovered her sordid affair with a eunuch. In five days, she made my gambling-addict elder brother pack up and get out of the marquis's residence, and even reclaimed the house he'd been hiding away from the family. In seven days, she confronted my scumbag father, who had been using my mother's dowry to support his mistress, before the clan elders and made him account for every last coin over the past ten years. My father was so furious he wanted to enforce the family rules, but she promptly produced the will my mother had left behind. “Master Xu, you're the one who should get out.” The clan elders tried to use filial piety to pressure her. She brought out the account book my mother had kept herself and tore away the whole Xu family's veil of respectability. The entire household erupted, while I huddled in my mindscape and clapped like crazy. “You're so cool, big sis! Give them more!” Lin Wan crunched on sunflower seeds with her legs crossed. “What's the rush? Your maternal grandfather's Shen family hasn't even made an appearance yet. When Old Master Shen storms into the capital with his silver, that's when the marquis's household will really turn upside down.” A feel-good tale of household intrigue, transmigration, face-slapping, and being doted on by the whole family. A modern office worker transmigrates as a mistreated legitimate daughter in ancient times and turns the entire marquis's household upside down.
