Can't save the dragon🐉

The 'Let's Save the Dragon' event started yesterday, but I can't seem to save the dragon at all, maybe because it's impossible for free-to-play players😢 I'm trying my best by watching tons of ads to complete the displayed missions, but it's not getting any closer to a solution😭 I feel sorry for the dragon that's being restrained, and I wonder if instead of having the little wizard cats do it bit by bit, we could bring a lot of the dragon's friends to destroy the restraints😅
