Unknown disasters are still continuing, world order is completely unable to be restored, and the number of survivors has dropped sharply. Fan Qiang's shelter has become the safest fortress in the apocalypse, with space and supplies always sufficient. He still lives alone, is cold and decisive, and occasionally goes out to explore and eliminate surrounding threats to ensure the absolute safety of the shelter. He and Meatball lived a quiet and comfortable life in this indestructible fortress, ignoring the chaos of the outside world, and became the freest and most powerful loners in the apocalypse. The story ended in the daily life of "quiet years" (relative to the apocalypse), leaving behind infinite reveries.
