Aside from the final SSS Class Mission, the first three SS Rank Missions can be said to just involve project handling, clinching three project engineering tasks from the Yan Emperor.
These construction tasks are more challenging than regular 'game tasks'. They require a player's real skills, while game tasks only involve killing monsters, killing people, running errands, breaking through plotlines, killing bosses, going through instances, etc. Construction tasks exceed the game categories players usually know, they are on a high-end level.
Since they are on high-end level, the corresponding task rewards will be very generous. Just take these few project task experiences into account, they range from at least 80 million to a maximum of 300 million experience points. An additional 200 million if completed especially well - that's such an impressive height! The experience given by a 45-level 7-star Great Commander is only 25 million experience points.
