The Heroine Mary Sue's Supporting Sister Is Reborn

As a cannon fodder sister in a Mary Sue novel, she was surrounded by the halo of the heroine all her life, and was dim until she passed away sadly in the name of evil. Gu Qingqing decided that if she could be reborn, she would definitely carry out her vicious reputation. But it is no longer as good as in the previous life, only in name but in reality. If you are blindly kind to tigers and leopards, you will only be eaten by tigers and leopards until not even the dregs are left.
