There was no pattern to the time and place of appearance of the floating island. Sometimes it might appear once every ten years, and sometimes it might not even appear once in a hundred years.
Because of this, when the sky Island appeared for the first time, it was regarded as an opportunity. Many cultivators would go there to find some spiritual herbs or Dharma artifacts.
However, for those big sects, the floating island was just a place for their disciples to train. There might be a lot of good things on the floating island, but for those big sects, it was not very attractive. On the contrary, the lives of some of their disciples were more precious than those treasures.
