The story takes place in 2012 after the end of the world predicted by the Mayan civilization. The "end of the world" predicted by the Mayan calendar is not a catastrophic cosmic collision or the destruction of the earth as humans think, but the beginning of an extreme climate change. The ice age returns, the earth's temperature drops sharply, and the climate gradually becomes colder, resulting in widespread ice and snow coverage around the world. The protagonist establishes a new tribe on the ice and snow at the end of the world, fights and annexes other tribes, and finally unifies mankind.
No idea, what the hell?
