So I went through 4 worlds (reanimating 4 crystals in each) and when I was in the 5th I knew that Airy was lying. It was right at the beginning of chapter 8. So I tried to just destroy the wind crystal and it worked. So I went through chapter 8 in like 2 minutes. Though I wonder, how long can you keep reanimating crystals before the main story leads you to destroy one? What happens if you destroy a crystal in the first world?
