I once read an introduction to a Douluo fanfic by an author. Not everything the protagonist does is right, and the existence of the Wuhun Palace is necessary. I personally don't blame the Seven Monsters, I just feel that Bibi Dong is a very capable person who should not be trapped by some external objects, and I want to give her a different ending. So she has complete memories of the parallel world, and at the same time, she also has a female soul like a modern royal sister who lives in her body.
Purpose: Everyone's life is their own choice
