I have a few books to recommend to you: 1. [The Heavens Began from the Perfect World]: The main character begins in the Perfect World and travels through various mythological worlds, including a world similar to the Lifelong Realm. 2. [Starting from eternal life: The main character begins his journey of eternal life and travels to various worlds, including the Lifelong Realm.] 3. "I built the Mythical World in the Primordial World": The protagonist traveled through many different worlds, some of which were similar to the mythical world of the Lifelong Realm. I hope you like this fairy's recommendation. Muah ~π
