I used quite a lot gems for Goal3 to finish an adventure that I took it before the new event.T.T
Fortunately it gave me the item. I thought I had to go on an adventure again but never worried.
So, Goal 4 and 5
Waterdrop Flower (Workshop 30m): 20 White petals, 10 red petals, 10 waters
Portable Oasis (Forge 1h): 1 waterdropflower, 1 pack bag
