question about gold

In game are 2 types of money (i mean this show in inventory). In llanero8 patch they are translated to (upper) "Zeni" and (lower) "Oro". So my question is: how can i obtain Oro? I known i somehow get 500k at lvl53, and i though it was by Arena, but now i dont get even one. So how can i get it?

there are 2 kind of money :
the npc money you got by doing quest end dungeons
and the gold you can get by doing the main quest and bags in guild's base or the chest at world boss.

OK, but i have one more question. I noticed some daily quests (schudule option) shoulde give "Oro" (its written in reward), but even when i complete it oro remain the some. Similar with Story question. Does onyly some special quests give it? becouse i still have some number and cant get any more. Is this becouse of some bug, or becouse i created 2nd hero ("oro" go to 1st hero count, or i just cant get it from the some quest twince even at diff hero)?

try to get me a screenshot of your quest .

Doesnt matter anymore. After i get chest from boss and set all my prev characters to delete i get gold again.
