I recommend the Infinite Nightmare Prophet. The main character, Long Yifei, entered the Nightmare Realm after his family was wiped out by a powerful enemy. There, he discovered that the Reincarnators in the realm were all natives of this foreign world. However, the Nightmare Realm he entered was a world that he was familiar with. It was based on novels, movies, comics, and movies on Earth. The Wise Man and the Mountaineer in this book were characters that appeared in the nightmare realm. I hope you like this fairy's recommendation. Muah ~😗
