Unfortunately for you, Friday is Purple Bloom Dragon day and we're now on Saturday's special campaign so if you did truly mean that you had manyus instead of dragons you'll have to wait for another week to farm the dragons you need.

Is there a daily limit for the Lv. 100 Bloom dragons? I can't get the third one if my life depended on it (on the same day)

lvl 100 bloom dragons drop randomly and very frustratingly. If you ask me, all chests on the 80 stamina dragon maps should be converted to gold chests, so they at least won't ever drop lvl 5 dragons anymore, only lvl 20/100 dragons. (Same thing with the Manyu maps, really, the 80 stamina maps should only have gold chests)
