Finally a Milestone!!

Finally reached Lv200. Just one more stage to clear and I'll be 200, and that's the end of the hidden quests! ...right?? The problem is the clear reward is only available until Oct 1st, 2 AM. I'm overflowing with gems right now, and coin exchange is also at MAX. It's a tight deadline to receive it~ If I fall asleep, I'm out! Oct 1st, 0 AM => Exchange coins to MAX (approx. 40000 gems) + use 1000 gems to gain EXP and get hearts Is that all I can do...?
