Thunder Mountain presented a wondrous sight during the day. At its foot was a lush, green forest. A thousand zhang up, this gave way to shrubs and tall grass. Another thousand zhang higher, the grass became sparse and withered. Further up, it gradually transitioned into a land of ice and snow. But for the final few thousand zhang near the peak, there was only the faint white glow of lightning, with not even ice or snow to be found.
From bottom to top, the colors changed from a deep green to a yellowish-green, then to a withered yellow, and finally to white.
Thunder Mountain was ten thousand zhang high, and the forest at its base alone was dozens of li deep. The trees in this forest grew to be exceptionally tall. A giant tree that took seven or eight people to encircle would be considered a king of trees in an ordinary forest, but at the foot of Thunder Mountain, it was merely an average tree.
