The Concubine's Daughter Reigns Supreme (Reborn)

This is a story about a woman who died full of resentment but was given a chance to be reborn. Mu Wan decides that if she has no means to get revenge, she'll make her own. After starting over, everything is different. Not only is life much more comfortable, she also meets the person who saved her life in her previous life. But... why is this benefactor so different from how she remembers them?

P.S. A heroine who works hard and grows on her own, with a ridiculously powerful golden finger. Everyone is ridiculously lovable. Family intrigue in the early stages, followed by court politics and palace intrigue?

[A cool, heartless heroine who never blinks when face-slapping her enemies x a hero who's carefree in public but henpecked at home, 1v1, sweet]
