All of are peak manhwas, some obvious and some underrated. Its ranked in order by how great it is.
PS. Those without chapters can be read in other sites like comick,io.
PPS. I have read all chapters of these manhwas so rest assured, they are GOOD. So ignore the initial ratings!
PPPS. NO ROMANCE in these except SSS-Revival Hunter, Tyrant of the Tower Defence Game, The Legend of the Northern Blade, AND Solo Levelling
