The blizzard on the Ice Plains can be large or small; a large one can sweep across thousands of miles, with howling winds that can press Foundation Establishment cultivators so hard that they can't fly, and even though Golden Core Stage cultivators can fly in it, their mana consumption would multiply by several times, and their speed would still be extremely slow.
It's also very easy to get lost, directly deviating from the destination by hundreds or even thousands of miles.
Moreover, there aren't many reliable landmarks on the Ice Plains, and the terrain can easily be altered by the snowfall, so even with a so-called map in hand, it's extremely difficult to find one's goal again once lost.
Once lost, one might easily venture into perilous zones or demon beast lairs due to unfamiliarity with the environment.
Therefore, if one wishes to search for something deep within the Ice Plains, it's usually necessary to find those cultivators familiar with the terrain to lead the way.
