(Apocalypse + reborn + pocket dimension + System) Disasters strike one after another, and the world teeters on the brink of collapse. First comes extreme heat, then the zombies, followed by a deep freeze, acid rain, dense fog, endless night, and earthquakes. After struggling to survive for ten years in the apocalypse, Su Ji is ultimately killed by someone she knows... When she opens her eyes again, she has reborn three months before the apocalypse, and her loved ones, who died long ago, are back by her side. She opens the brocade pouch her master left behind and unexpectedly activates a System and a pocket dimension. Before she can even celebrate, the System assigns her an impossible mission: [Keep three billion people alive for ten years!] Su Ji is worried she has no money to stockpile supplies, but her usually low-key mother promptly hands her one billion yuan. She stocks up on a billion yuan worth of supplies, kills zombies, collects crystal cores, opens apartment buildings, starts farming, develops technology... Ten years pass in the blink of an eye.

You have completed the mission. Your reward is now ready for redemption. Please choose...”
