Wind is everywhere, but when it disappears, it doesn't mean tranquility. In the real wind belt, the calmer the place, the more likely it is for a strong storm to appear in the next second due to the changes in airflow!
Therefore, at the last moment, Chu Mu chose to fly towards the area with the strongest storm!
When Chu Mu was flying towards the storm, it wasn't when the storm was the strongest. Instead, it was when the storm was gradually weakening. As the strongest storm weakened to a stop, and after it stopped, there would be a relatively calm period. This brief calm was Chu Mu's only chance to escape!
This guess was correct, and that's how Chu Mu managed to tear through the dimension and successfully escape!
On the other side of the Wind Cave is the Storm Space. Passing through the Storm Space, Chu Mu returned to the Ice Mirror World.
