When the super cold wave sweeping the globe turned the world into a frozen purgatory of minus 70 degrees Celsius, former scientific researcher Lin Xiao was the only exception. He woke up from the frozen laboratory and found that he had become the only "warm-blooded human being" in the apocalypse, a walking living fire that was immune to extreme cold.
This body did not bring warmth, but instead attracted endless covetousness and murderous intent. Brutal predators regard him as a moving energy source, and the mysterious "Ring of Judgment" lists him as a "key key" that must be captured. In the process of struggling to survive, Lin Xiao discovered that this devastating extreme cold was not a natural disaster, but a cruel selection of human civilization led by a terrorist agreement called "Eternal Winter Night".
Side by side with him is Mo Qianqian, a perceiver whose life experience is a mystery and is burdened with the apocalyptic truth left behind by his mother; Amy, a hacker girl who is proficient in technology and looking for a way out in the ruins of data; and Frost Whisper, a mysterious ice descendant who is both good and evil and has strange powers. They form a desperate team struggling to survive in the icy hell.
From abandoned cities to underground ruins, from mutant lairs to the enemy's lair "Silent Peak", while Lin Xiao continued to explore his own secrets and the origin of the apocalypse, he also gradually came into contact with a more grand truth about the universe - the existence of the "Observer Protocol", the origin of the "Original Ice Core", and the final choice that mankind must make in this life-and-death test that sweeps the planet.
Is it to serve as a "tinder" to ignite the hope of civilization's revival, or to become a "firewood" to fuel the flames of destruction? In this frozen doomsday ruins, an ultimate adventure about survival, truth and redemption.
