People Are in the Last Days, Sign in to Survive

There is no system in the apocalypse: "Brother, please do a good job and give us something to eat. There are zombies outside and we can't survive anymore!" A system for the end of the world: "It's hard to survive? Do you mean zombies?" How can I get points if I don't kill zombies? There are so many good things in the mall. Have you ever seen a person's physique become stronger after being exposed to the sun? To be honest, signing in can only rely on luck. Killing zombies can lead to a hug like this.
