As far as I know you will have to do all the side quests, but is fast if you are GM, if you have to kill the 20 bargons, take the quest, choose a field like /field 2, summon 20 bargons typing /monster "Bargon" 20 , and after killing them, type /field 3, and talk to NPC, so you can take the quest guide on SunnyZ website and finish all the side quests.
