In 4099 AD, Blue Star 2 returned to the Ice Age overnight. The sky was filled with frost and snow. Human civilization was regressing rapidly. Blue Star 2 was about to end its lifespan. Dr. Yang's prediction became a reality. Countless pioneers used time capsules to go back to the past to find a way to save the world.

Crystal clear ice crystals are the key to the door to another world. An elegant gentleman stands in the cold wind, inviting you to watch a grand curtain call.
