The Heroine Who Travels Through the World of Demons and Immortals Becomes an Excellent Demon Immortal

Yiyou'er has been watching "Balala Little Demon Fairy" since she was a child, and she especially likes the magic performed by the demon fairy in it. I can't dislike the little black devil fairy inside, I can only feel sorry for him. Looking back at the two sisters Ling Meiqi, I feel a bit noisy. After traveling to the Fairy Castle, in order to win Xiaoyue back, he did not hesitate to practice black magic himself. But in the days of the human world, the demon fairies specializing in dark magic on the dark star planet that has been hidden for many years in the universe are ready to move, and the magic union occasionally intervenes. What kind of storyline will happen to Yiyouer here? Book lovers, please be merciful. It may not be a very good first time for me to write a fanfic about this kind of magical world. If you want to read it, read it; if you don't want to read it, abandon it. Don't say that I am bad at writing. After all, I need to improve.
