In the "Qianren Snow Mountain", which is covered with snow all year round, there is a set of survival rules that are completely different from the outside world. The snow here can swallow up memories, inhuman beings lurk in the glacier crevices, and the snow viewing platform on the top of the mountain is a forbidden place. There is a legend of the "Snow God" circulating in the area. Tourists and guards must strictly follow the rules posted everywhere. If you are not careful, you will fall into an irreversible situation. All the rules are contradictory but have hidden logic. The truth is like a mountain buried in a snowstorm, waiting for the brave to dig out.
