After becoming the villain's eldest sister, I take charge of the whole family

Xie Linghe was taken away by the underworld by mistake and traveled to a book. But this family is full of villains. Fortunately, the underworld made up for her with a system. Imperial examination system for prosperity?! I am a woman, and you want me to take the imperial examination in ancient times? What about the promise that I can be a salted fish and enjoy life? I don't agree! What? You can bind a secondary system to your immediate family members. Okay. The eldest brother is a scumbag, and he is sent to the scumbag transformation system (imperial examination version). The second brother is a love-brained man, and he is sent to the love-brain transformation system (imperial examination version). The third brother is a gigolo, and he is sent to the gigolo transformation system (imperial examination version). The fourth brother is a fence-sitter, and he is sent to the fence-sitter transformation system (imperial examination version). If you can't die from studying, study until you die! Soon. Boss Xie took the exam...
