I recommend a fantasy novel that is similar to the "Immortal Path to the Underworld" called "Travels in Illusions". It was written by the author who had his hands on the world. This novel was also about an ordinary person who became an immortal. He went through countless hardships in the Otherworld and finally obtained the legendary Flower of the Immortal Dao, becoming a powerful Immortal Emperor. If you like fantasy novels about the struggles of the martial world, I believe that "Travels in Illusions" will satisfy you. I hope you like this fairy's recommendation. Muah ~๐
