So there are
3 ways to see what you need to kill
1st way is this
1. Open the Map

See in the red circle that's the place you have to kill the mob or the item u need to collect . go to the red circle
2.
Open you'r quest
3.
Go To information

See the red chinese letters written there?
4.
Look it up , much it with the mob.
If the letters much together that's what you have to kill . if not its not!
2ND WAY IS THIS!!(AND ITS MUCH EASIER)
(This mode doesnt work anymore cause of the update . but what the hell its a copy paste)
NOTE: YOU NEED SCOUTER A CHIP TO USE THIS METHOD
1.Open you'r scouter and scan it.

See the happy face up there . that means its the mob you have to kill in the quest too simple right?
[B]3RD WAY IS PRETTY OBVIOUS/B]
1.Take the quest and go to the red circle
2.Look at you're mini map at the right top of the screen
3.Noticed the blue things with the question mark (?) on it?
4.Well that's what you need to kill.
Thanks For checking this out . Easy . didnt really need to make a thread about it
