In the Ninth Year of My Death for the Male Protagonist, I Replaced the Female Protagonist

After my clan was exterminated, I became the last nine-life fox in the world. Something called "the system" found me: "As long as you die nine times for the children of destiny in this world, you can ascend to the fairy world." After ascending to the immortal world, I have the opportunity to reshape the souls and bodies of my people and revive the Nine-Life Fox Clan. So I reached an agreement with the system, sacrificed my charming voice, forcibly transformed into a human, and became a stand-in maid next to Xie Jiale. Whenever Wei Jingyun was in a life-or-death crisis, I would wear Xie Jiale's dress, cover my face, and block the fatal blow for him. Until the last substitution, I heard the conversation between the system and Xie Jiale—— "Bai Xiyao isn't suspicious, is he?" "Of course, she thought she would be able to ascend immediately..." "Hey, I thought she was so smart! She didn't even think about it. There has never been a Nine-Life Fox who has died nine times and still survived. How could she be an exception?"
