A post-apocalyptic story is a mess, an atypical post-apocalyptic survival story.
There are golden fingers for cultivating immortals, supernatural powers, monsters, systems, perversions, etc., All stewed together.
There are good and evil people, joys and sorrows here, as well as laughter and warm food. The story of a big family working together to build a home in the last days.
Mission: Cooperation, teamwork and comradeship spirit
