Genshin Impact: Weird? I Just Hope It’s All a Dream

[Transmigration] + [Anomalous World] + [Horror] + [Genshin Impact] + a rewind-like ability (The story starts slowly, and characters will die… If that bothers you, I don't recommend reading it.) I'm Xia Yu, and I've boarded a one-way ticket across worlds. I thought it would be an orderly otherworld, a place where people could embark on an adventure. But it was only a breeding ground for rot and fear. It… or rather, they were all “sick.” Are those twisted possibilities, or anomalies, really as simple as I understand them to be? ???: So noisy… insects. A man claiming to be the Great Demon King spoke irritably, his pair of glowing white eyes fixed on everyone… Perhaps people aren't as resilient as we imagine. A girl's emotions were on the verge of collapse… Lumine: “I can't take this anymore!” Xia Yu: “I wish this were all just a dream…” In this anomalous world, understanding the anomalies is the only key to survival and liberation. Hahahahaha! The truth, I have solved it! Power! What I need… is enough power to turn everything around! ???: Interesting. Then answer me: what is the meaning of power… This blurb is weak. Please move on to the main story.
