You Get Promoted, I Get Rich: The Fiery Widow and the Rough Young Master

With no other choice, office worker Wei Yun lets loose on the boss who's been harassing her, then quits in a blaze of defiance. On her way home, she gets a call from her own father, who wants her to stand up for her stepmother. While she's giving him a piece of her mind, a car hits her as she crosses at a traffic light. ??? Is the Grim Reaper after me or what! After all that, she transmigrates into the body of Widow Wei in Li Village. From the start, her brother and sister-in-law are trying to sell her to a creditor for ten taels of silver! Fine. She'd rather go with Shen Yanei, ruggedly handsome, broad-shouldered and slim-waisted, just her type, than stay with the Wei family. Her cheap mother-in-law, Shen Zhangshi, has only two skills: crying, and crying while offering incense to her deceased father-in-law. Her dim-witted sister-in-law, Shen Lian'er, goes from hating her to fighting her own brother over who gets to call Wei Yun sister-in-law. All it takes is getting tricked once. The four children in this blended family are forced to become prodigies. After marrying Shen Yanei, Wei Yun finds herself caught up in one case after another: an official's son sneaks into his father's room in the middle of the night to steal valuables because his gambling debts haven't been paid; a young cousin is murdered to cover up her pregnancy by a young master; a theatrical troupe openly kidnaps children, while secretly taking them away to brainwash them... The cases grow bigger and bigger, and the officials rise higher and higher in rank. Wei Yun follows along, her status rising with theirs. She opens a baozi shop, a diner, a restaurant, and more... Her earnings keep growing.
