Botanist Ji Linyuan and special forces soldier Lei Xiao died together during the third ice storm of the apocalypse, but unexpectedly returned to life three months before it began. In his previous life, Ji Linyuan was betrayed by his lover and survived alone in the extreme cold for three years. He returned with his memories and a rare plant-growing space. Lei Xiao, meanwhile, was an ability user at a military base with the power to control lightning, but in the last apocalypse, his trust in the wrong people had led to his entire squad being wiped out. Each made preparations for the coming apocalypse: Ji Linyuan used his plant-based space to grow cold-resistant crops and secretly stockpile supplies, while Lei Xiao used his ability to reinforce an underground shelter and train survivors. By chance, the two met during an arms deal at an abandoned military base in a blizzard. Lei Xiao mistook Ji Linyuan for an enemy, but after a clash of lightning and plants, they discovered that they shared the same goal: preparing for the extreme-cold apocalypse that was about to come.
