[Dream of the Red Chamber] The Lin Family Widow

After transmigrating as an unmarried daughter of an official family, Rong Qingyu finds herself with a father who died young, a chronically ill mother, no siblings, and a pack of greedy uncles eyeing her family's million-tael fortune. But she finds herself an excellent marriage. She marries Lin Ruhai, her father's contemporary and the Imperial Salt Commissioner of Lianghuai, who is nearly fifty, becoming his second wife. When Lin Ruhai falls gravely ill, [Rong Qingyu, a first-rank Lady of Honor appointed by the imperial court] looks at Jia Lian, who has hurried to Yangzhou with Daiyu, and smiles faintly: Nephew Jia, what did you say you were going to do with the Lin family's estate? "Ruhai married me before he died, so I am Yu'er's rightful mother. Naturally, I have a say in her affairs." "You're short on money for the imperial visit? Then build a smaller garden. Why are you telling me?" "Daiyu is the daughter of a first-rank Grand Tutor. As for your Baoyu... I'll say no more. Let's not make this uglier than it needs to be." "Afraid of offending people?" Rong Qingyu smiles calmly as she puts an arm around Daiyu. "Yu'er, just trust me. I won't let you suffer even the slightest injustice in this life." Years later, Daiyu looks back on her mother Rong's life. She defied convention and did one astonishing thing after another, making the nation rich and strong and winning fame throughout the land. Clad in robes embroidered with cranes and wearing a gold seal at her waist, she truly never let Daiyu suffer even the slightest injustice again. - The female lead has a golden finger. This is a wish-fulfillment story. - The female lead is no saint or perfect person. She can even be called ruthless. - A love interest appears later, and it is not Lin Ruhai. The love interest is definitely a man. - An alternate setting, not the Qing Dynasty, with original worldbuilding. - No character bashing, but that doesn't mean everyone is purely good.
