Beneath the ice field lie numerous lakes and rivers; otherwise, there wouldn't be enough moisture to form such a thick ice layer.
Topographically speaking, the terrain of the Ice Barbarian Country is significantly lower than the surrounding nations, so it's speculated that underground water sources from various countries eventually converge here, with the ice field taking on a role similar to the Dragon Abyss Marsh, transforming immense moisture into snow and ice for storage.
Although the ice layer on the ice field is thick, it exhibits fluidity, sometimes creating lakes out of thin air or forming large basins.
There are also places on the ice field with special environments where unfrozen lakes can form.
In summary, this ice field is a place devoid of life yet filled with miracles.
Zhou Chun is not a natural scientist, so he doesn't care about how the ice field is formed or how those unusual meteorological phenomena take shape.
