Solo max level newbie
Sss class suicide hunter
Return of the sss class ranker
Honestly check Asura scans and you'll find a ridiculous amount of those manhwas

These are some I def recommended if you haven't read it yet!!
I have multiple lists that contain similar storylines and genres to Solo Leveling. Please check them out if you want more recommendations! Otherwise, Poison Dragon: The Legend of an Asura, Standard of Reincarnation, I Reincarnated As The Crazed Heir, The beginning after the end, Leveling With The Gods, Return of the Frozen Player, Nano Machine, Legendary Youngest Son of the Marquis House, and, Genius of the Unique Lineage are all similar in genre to Solo Leveling.
manhwas that are similar to solo leveling, omniscient reader, lookism, & my school life pretending to be a weak person? (if you couldn’t tell, i like weak to strong with strong male protagonists) preferably not heavy in romance
