An "extreme cold catastrophe" suddenly occurred around the world. The temperature plummeted to minus 60 degrees, power was cut off, communications were paralyzed, cities were reduced to frozen ruins, and mutated creatures were rampant in the severe cold. Su Lin, a former fighting instructor, rescued the injured engineer Lu Chen when the martial arts gym was attacked, and the two worked together to survive. Without the blessing of the system or extraordinary powers, Su Lin relies on her superior force to kill mutant beasts and protect the weak; Lu Chen relies on his mechanical knowledge to repair heating and make weapons. Facing the shortage of supplies, the test of human nature, and the tide of mutant beasts, the two went from distrusting each other to fighting side by side, fighting a way out in the frozen apocalypse, and gradually uncovering the secrets behind the extreme cold disaster, vowing to protect the last piece of human pure land.
