The few masters of the sky dance realm, including ghost spirits, didn't fly in the sky because the destructive desert was very strange. There was a lot of destructive power here, which affected the professionals. If the professionals wanted to fly in the sky, they had to use their own power to fight against the destructive power, which would consume their power faster. In such a place, it was very difficult for them to replenish their power, so when they came to the destructive desert, they were all shocked. No one at the Wukong level could fly, so it was too dangerous.
