Survival in the Mist: My Shopping Mall Is Refreshed Every Week

The fog is shrouded, and the end is coming quietly. Countless zombies appear, a large number of mutated animals, a two-story mutated cat, a mutated dog covered in fire, a terrifying giant python circling a skyscraper... Everyone's first priority is to find ways to survive. When you wake up, you find yourself in a closed classroom, with zombies knocking on the door constantly outside, and you are already unable to move because of hunger. In times of crisis, if you successfully connect to the Internet, you can refresh the system mall every week: [Bread], [Purified Water], [Gene Enhancement Potion], [Glock Pistol], [Exoskeleton Armor], [Extraordinary Bloodline], [Magic Scroll]... So you made your first recharge and bought bread, coke, and a pistol loaded with bullets.
