A sudden "Red Fog" disaster swept across the world. 70% Of humans mutated into bloodthirsty "rotten beasts", cities fell, and civilization collapsed. Lin Mo, a useless programmer, accidentally activated his ancestral old mobile phone while escaping, and bound it to the intelligent life "Zero" from the future. Zero can not only analyze the weaknesses of rotting beasts and plan the optimal survival route, but can also turn waste materials into food, weapons and even genetic enhancers through "energy conversion".
From ordinary people living in rented houses to a post-apocalyptic leader who established the "Ark Base", Lin Mo led Zero to break through the tide of corpses, battle wits with the "Black Crow" mercenary group that plundered resources, and met retired special forces, botanists, mechanics and other partners. However, he discovered that there was a conspiracy of alien civilization invasion hidden behind the red mist, and Zero's existence was the last hope for mankind to reverse the defeat in the future. When the rotting beasts evolve wisdom and alien probes arrive on Earth, Lin Mo must make a choice between protecting his companions and launching the "Civilization Restart Plan" - this doomsday is never a survival game, but a desperate counterattack by human civilization.
