Running an Underground City in the Apocalypse

Seven days before the cataclysm, unemployed engineer Zhou Qi inherits an underground mall slated for demolition and unexpectedly activates an underground city management System. Repair a shop, and you unlock a survival facility; take in someone who truly needs help, and you earn a resource for civilization. When the city is plunged into power outages, blizzards, and struggles over supplies, others fight over food while he grows vegetables underground, generates electricity, and purifies water, transforming the abandoned mall into humanity's last safe haven.
