I'm a Vicious Old Lady [Quick Transmigration]

After retiring from the Protagonist System, Ning Yao was sent by the Villain Redemption System to retire in an old lady's scenario. She thought she'd be spending her golden years as the kindest, most benevolent elder in the family. Instead, she became a meddling, unreasonable, despicable old woman. In these worlds: She wants to marry off her granddaughter to a man with dementia, just so her grandson can get a wife. She wants her son to divorce his first wife because she can't bear him a son. She keeps an obsessive eye on her young daughter-in-law every day, afraid she'll fail to remain a widow... Ning Yao: How am I supposed to redeem this? System: Just redeem it anyway. So after she transmigrates: Her granddaughter understands that Grandma dotes on her little brother because she's afraid the family will be left without an heir. After sincerely repenting, Ning Yao raises her grandson and granddaughter to become first-rate scientists. The first wife understands that her mother-in-law wanted her to divorce because her husband had been cheating for a long time. After cutting ties with her son, she builds a prosperous life with her daughter-in-law. The young daughter-in-law understands that her mother-in-law is afraid the village men will take advantage of her. Once the family is doing well, she treats her daughter-in-law like her own daughter and gives her a splendid wedding. Theme: A good life is something you create yourself.
