The place Catherine pointed to was a vast subterranean space. Within this underground area of over a hundred thousand square meters, many low trees were sparsely growing, their vegetative scent slightly dispersing the scorching heat filling the air. On one of the slopes within this space, the ceiling had fewer crystal shards than other locations, making the temperature on this slope significantly lower than the surrounding forest. The temperature difference even caused a gentle breeze to flutter the leaves on the treetops, causing them to rustle. In such a hot environment, the breeze caressed their cheeks, bringing a refreshing sensation to the girls and dispelling the fatigue brought on by the sweltering heat.
