Where do I find the white and yellow card to elona maxs secret cargo I have 6/8 and I can't find anyone to give me quests?

Also I found a glitch for grinding on stickman of war you just go to your setting switch the date to next day claim your free rewards in the shop just keep repeating that and you will be grinding good resources and gems also after everytime you switch the date and go back to regular date the hours increase before you can claim your rewards right now I have to wait 8856 hours thats probably like 456 days. But it does not bother me?
