When I up level 70, I go to skill master and I left click in rankup, and skill master speak with me " you have an undergoing quest ". Help me, I can't do quest tier4 >_<

That would lead me to believe that you haven't finished one of the other quests, press Q ingame and it should tell you which one you haven't finished.

To drop the quest weapon, do the following:

 

1)Place both inventories full of items (so the quest weapon doesn't fit in neither of the inventories).

2)Place the quest weapon in [weapon slot 1]. Place another weapon in [weapon slot 2].

3)Open inventory, view of weapon slot to [weapon slot 1] (so you see the quest weapon in the weapon slot).

4)Trade a person then quickly pick the quest weapon from your weapon and press W (so now you should be holding your quest weapon in your cursor, the weapon slot view is on [weapon slot 2] and you are trading with the person).

5)Now cancel the trade (with the item in your hand) and the item will be dropped!
