After Passing Through the Book, I Saved the World by Whitewashing the Protagonist

Forget about wearing a book, she also dressed up as a vicious female supporting character who has made a big mistake. It would be best if she could never meet the male and female protagonist again in this life, but Bai Lulu came here to help the male and female protagonist reduce their darkening level and save the world! Bai Lulu expressed that she was very tired, as the hero and heroine's deadly sword immediately pierced her throat. From the first day of entering the book, Bai Lulu has been running wildly on the road to clean up the male and female protagonists. She takes great care of the female protagonist to prevent the delinquent girl from falling into the trap of the old man. She treats the male protagonist heartily and sacrifices her life for righteousness again and again, fearing that the male protagonist will kill her. Ku Lei doesn't tell anyone, but her villain mother wants to kill the hero and heroine every time! Bai Lulu felt so tired, Bai Lulu wanted to retreat, Bai Lulu couldn't bear it, Bai Lulu really wanted to sleep...
