Chapter 693 Northwest Beacon Fires 4

"A year ago, we noticed such a tendency: the frequency of sandstorms in the Kneecap Desert had abnormally increased, too frequently compared with historical climate records, so we speculated whether there were undead creatures causing mischief deep in the desert.

For this reason, we dispatched countless scouts into the desert over the past year, and now we finally have a rough result."

Yu Zhengxing began to discuss the matter at hand, "In the depths of the Kneecap Desert, about two to three thousand li away, there is a valley named Xunfeng Valley. After our meticulous investigation, we believe that the sandstorms originate from there.

The topography around Xunfeng Valley is unique, with several sand mountains surrounding it, easily forming valley winds; coupled with the underground spirit vein's fiery nature, it leads to a significant temperature difference overhead and turbulence in the stratum. A slight climatic change would trigger a sandstorm.
