How to trigger NPC quest

I think you can get 1 per day for each type of item from each map.
But you may give more than 1 per day to NPC.

From NPC as reward, basically, you will get green or blue item of that map.

For example,

In Fall Forest, you will get Iron Ore, Twig, Bone, Flint etc and of course new dollar.
Like that, its depend on the map.
