Xia Nan had already learned that much from village chief Clapham before he came.
However, because gray rocks were scattered everywhere and the terrain was monotonous, even during the safe periods when the Axe-Beak Bird flocks had not appeared, few villagers had the leisure to venture deep inside and explore.
At the moment, he seemed to have been following behind the Adventurer party for quite some time.

Compared with the latter, however, once this mist, which seemed like nothing more than a normal natural phenomenon, reached a certain threshold of density, it even possessed some kind of confusing effect.
Xia Nan observed it very carefully. The gray-white mist pervading every corner of his vision not only made sound travel sluggishly and fade within it, but also seemed to carry a slight ability to distort one's sense of direction and distance.
