When the Ice Age suddenly descends, civilization collapses in temperatures of minus sixty degrees. Zhao Yi and Ju Jing, an ordinary married couple who work as interior designers, are starving and freezing when thugs break into their home, bringing their brief, agonizing life in the apocalypse to an end.
When they open their eyes again, they have returned to three months before the deep freeze began.
This time, armed with memories of their reborn lives, the couple begins a thrilling countdown to prepare for what's coming. Zhao Yi fires up his professional design software and transforms their top-floor duplex into an ultimate fortress equipped for blast protection, energy storage, and ecological recycling. Ju Jing plans an indoor farm and a survival training room. While their neighbors are still panicking over the sudden cold, the shelter they have built with ingenuity and hard work is already taking shape.
Snow and ice engulf the city, and humanity begins to crumble under the pressure to survive. As their maddened neighbors surround the door with weapons in hand, Zhao Yi smiles calmly at the monitor: “Welcome to our eternal winter safe house.”
But the world beyond their fortress is far more complicated than they imagined. During years of frozen isolation, they must cope with a steadily worsening natural environment while protecting the light of humanity amid the ruins of order and morality. Then one day, the sound of an official rescue team's engines breaks the silence. A new choice lies before them: stay forever in this refuge, or use the experience they paid for with their lives to help humanity rebuild its civilization?
This is an epic survival story about an ordinary couple in an extreme environment, and a magnificent tale of love, protection, and passing the torch of civilization down the generations. When spring finally melts the ice, the miracle they created with their skill and ingenuity has already become a new era
