Anyway, the "terrains" of warzone they're talking about are always about the cities (as if the battles were impossible to be occured outside of the cities while Satan and 7 of the 12 devils generals had never battled in Radiant Continent). As amazing as Satan was, I guess it's impossible for him to collect information about the alliance's current force and the new "terrains" of Radiant Continent while recuperating in just two years (like SYX did while cultivating in just three months), huh?
