Botanist Ji Linyuan and special soldier Lei Xiao both died in the third ice storm of the apocalypse, but were unexpectedly reborn three months before the outbreak of the apocalypse. Ji Linyuan, as a survivor who was betrayed by his lover in his previous life and survived alone in the extreme cold for three years, brings with him the memories of his previous life and the space of rare plants; Lei Xiao is a superpower in the military base who has the ability to control thunder and lightning, but in the last apocalypse, his team was wiped out because of his gullibility. The two of them each prepared for the end of the world. Ji Linyuan used the plant space to cultivate cold-resistant crops and secretly stockpile supplies; Lei Xiao used supernatural powers to strengthen underground shelters and train survivors. During an accidental arms deal, the two met at an abandoned military base in a snowstorm. Lei Xiao mistakenly thought Ji Linyuan was a hostile force. After a confrontation between lightning and plants, they discovered that they had the same goal - to prepare for the coming extreme cold apocalypse.
