@Anthony Gabriel meridian opening, martial apprentice, martial master, martial grandmaster, martial king, martial emperor (wu Huang in the novel), martial Saint (wu sheng in LN), martial g** (emperor in the LN).
@Anthony Gabriel each realm has 1-10 ranks or levels, level 10 is the peak. So like, for example: martial king 1,2,3,4,5,6,7,8,9 then peak martial king before breaking through to wu Huang.
