Hello, I am searching for a novel I read in which the female lead is an illegitimate daughter and she gets reborn from dying due to mistreatment after she is brought back to the real home. She seems to wander in void for thousands of years after dying and is only given books to read. After finishing all the books she is finally reborn and even gets some powers or something. She goes to the moment when her half sister is hosting a party. It is a Chinese novel and I think the female lead's surname might be gu. These are all the details I remember and hope somebody can tell me the name of this novel.
No I don't. But I remember that the FL was a cultivator and goes on to save the world at the end of the novel.
