Was there any novel recommendation about Daiyu being the female lead and possibly transmigrating or reincarnating, as well as Lin Ruhai having a concubine?

The female protagonist is Dai Yu (I don't know if she's wearing it or if she's reborn). Lin Ruhai has a concubine who transmigrated. Later, through the female protagonist's plot, the concubine was captured by Lin Ruhai and interrogated. She knew the future of Dai Yu and the Jia family. (At this time, Jia Lian went over to be a guest. It was Grandmother Jia who asked him to see if Jia Min was dead or not. Jia Lian was then guided by the female protagonist to improve himself and even exchanged letters with the female protagonist.)
P.S. This novel could be a comprehensive one, or it could be a quick-wear one.

Answer 1

I recommend "Dream of the Red Chamber and the Return of Daiyu" to you. This is a classic derivative novel written by the author, Moonlight 123. The story was about how the reborn Daiyu changed the ending of the story of 'Dream of the Red Chamber', and Lin Ruhai's concubine was also one of the important characters. I hope you like this fairy's recommendation. Muah ~😗
