The dragons are such giant clowns. They are so arrogant and full of themselves that anyone with a little bit of skill and experience can lead them by the nose as much as they want. Much of the security on the dragon islands is based on nothing but "nobody would dare". This allowed Yang Kai to steal all the mature dragon flowers with zero effort and now it's about to grant Wu Kuang a royal dinner. What kind of security is that supposed to be? No wonder the whole dragon clan is heading for extinction.
