In the year 2525, when technology is highly developed but traditional survival skills are severely lacking, a sudden solar flare event causes the world to enter an extremely cold apocalypse at minus 60 degrees Celsius. All high-tech equipment fails and human civilization is in danger. The protagonist Zhang Ergou, a working boy from the Northeast, was reborn before the apocalypse. With the survival wisdom of the Northeast engraved in his DNA and the "super hoarding system", he lived a prosperous life in the apocalypse by cooking on the stove, hoarding sauerkraut, and eating iron pots. However, due to the huge information gap, all of his returning-to-nature survival behaviors were misunderstood by other survivors as "oracles" and "tests" of a god-level civilization, and he eventually passively became the savior of human civilization.
