Since the battle of ancient devils, the restrictions in Devilfall Valley's outer valley have gradually weakened. Over the years, the outer valley has been opened to ordinary cultivators.
However, as the number of treasure hunters increased, most of the rare minerals, spirit grass, and spiritual wood in the valley were quickly swept clean. Only in extremely hidden, yet-to-be-discovered corners might one occasionally find decent items, but that heavily depends on one's luck and fortune.
As a result, the number of cultivators searching for treasures naturally dwindled over time, and now the outer valley has become little different from ordinary places of cultivation. Only occasionally do some low-level cultivators come by to try their luck.
In contrast, the inner valley of Devilfall Valley has gained an increasingly fearsome reputation.
