If you want to read an urban novel where the main character is immortal, I have two here to recommend to you. The first was "Unfettered Undying Body". This was a novel written by Young Master Feng. The main character was an immortal being with superpowers. Next was "Eternal Life", a sci-fi futuristic novel written by Bo Yujing. The main character was also an immortal existence, living in a highly technologically advanced interstellar world. I hope you like this fairy's recommendation. Muah ~😗
