you have to do do the 7 demon lord quest first you have to be tamer king, get 17 or 15 i think then check if you beat quest 17 get out of the farm then Calumon will call you then the quest starts. beat the first 6, Daemon, Beezlemon, Barbamon, Lilithmon, Leviamon, Lucemon cm then you'll have to face Belphemon at destroyed belt but he summonds the 6 back to life then defeat all 7 then you get Beezlemon's scan data. Go back to your digi-farm then you get calumon's scan data (its apt is 99)
