Flying Snow and Sword

It was already September 23rd. In the Changlong Inn in Gaochang Town behind the snow-capped mountains, some strange people gradually gathered. A strangely silent swordsman, a man with a feminine appearance, and several famous families all gathered in this small inn at the foot of the snow-capped mountains. People died in mysterious circumstances one after another in the inn, Gaochang Town turned into a deserted city overnight, and a group of people fled to the snowy mountains. When the heaviest snow falls after the winter solstice, the snow-capped mountains will be sealed, and the vast grassland behind the snow-capped mountains covered with heavy snow will also be sealed. Carefully crafted work ~O(∩_∩)O~
