The sudden disaster plunged the earth into a frozen "nuclear winter."
After the disaster, with the help of the three prophets, scattered humans rebuilt the "Snowy Tribe" and started a new life with primitive simplicity.
During an accidental excavation, young DeWitt and his self-defense friend Martin discovered a long-buried ice coffin underground. A pale-skinned girl sleeps in the coffin, bringing ancient truths and secrets that break reality.
The teenagers who learned the truth walked forward in the snowy land. They will go to the Ice Crown Tower standing in the center of the world - it is said that the princess of ice and snow lives there, the queen of the snowy land.
"Even the world right in front of you will completely fall apart at some point. That may be a million years from now, or it may be in the next second."
The girl shook her two slender fingers, her eyes were dim and cold, without any emotion, like ice buried in a lightless cave for thousands of years. "You have only two choices at this moment, either to be content with the status quo and obey your fate. If you are lucky, you will live a peaceful life until the end of your life."
"If you choose the second option, go find it."
Aviva's figure gradually became transparent, and her black hair, as messy as dead grass, shone bright blue in the snow. The snowflakes were beating at her, roaring and tearing at her clothes. The girl finally smiled slightly and made a hug gesture to DeWitt from afar.
"Go to the vastest snowy areas and look for spring."
