Because the Wind Element was excessively active, it compressed the space for other magic elements, resulting in the inability to use any magic other than Wind Magic in this area, while the power of Wind Magic was greatly enhanced.
The two thought of this place because of the existence of the Kylin Arm.
Unlike the characteristics of the Wind Erosion Valley, the Kylin Arm has the ability to absorb the Wind Elements in the surrounding environment. For instance, previously in the cave, the Kylin Arm absorbed all the Wind Elements, rendering all Wind Magic unusable in the cave while magic of other elements could be used normally.
So, what would happen if the Wind Kylin Arm was placed in the Wind Erosion Valley, where only Wind Element existed?
An area with only Wind Element and a device that only absorbs Wind Element — could their combined effects create a temporary Magic Vacuum Zone?
