In Loushang City, Zange Region, three survivor settlements had already embarked on a great migration. However, the rest of the survivor settlements remained as they always were, going about their business as usual. Most people even thought they might have to spend their lives in this desert.
Yet, some noticed something out of the ordinary. Recently, sandstorms have become more frequent than usual, and most strangely, the number of monsters around the oases was increasing rapidly. Large numbers of desert wanderers were frequently attacked and suffered greatly, starting to retreat back to the oasis areas, hoping to seek refuge.
