Genshin Impact: I Am the Demon God of Yin and Yang

[Group portrait, time travel(?), Heroine, no harem, no system] Luo Yue came to Teyvat and became the demon god of yin and yang. From then on, she kicked the demon god with her feet and pointed at the law of heaven with her sword... Of course, it was impossible, at least not now. She is so bad that she can only survive in troubled times. As for saving people... Sprinkle it~ I am a newbie writing a book. The previous outline was written when I was in junior high school. The writing is terrible. Please forgive me. And I'm not an originalist!
