Well, 'Solo Levling Light Novel' mainly focuses on a character's journey of solo leveling. In this kind of light novel, you can expect a lot of action - packed scenes. The protagonist usually starts from a relatively weak state and gradually becomes stronger through his own efforts. There might be different power systems, like magic or special abilities, that the character discovers and hones during his leveling process. It also often includes elements of adventure as the character ventures into unknown places in the story world.
