I'm not entirely sure specifically what a'solo leaving novel' is. It could potentially be a novel about a character who leaves on their own, perhaps on a solo journey of self - discovery or to escape a certain situation.
I'm sorry I can't recommend any specific'solo leaving novel' as the term is not a common genre name that I'm familiar with. But you could try searching in literature databases or asking in book - lover communities.
The story of Solo Leveling is about a weak hunter named Sung Jin - woo. In a world filled with dungeons and monsters, he starts off as an E - rank hunter, which is the lowest rank. But he gets a mysterious system that allows him to level up and become extremely powerful over time. He faces various dangerous dungeons and strong monsters, and gradually rises to become one of the most powerful hunters in the world.
