"Let's head back," Lin Wu shivered, returning to the campfire. No need for the Beast Trap, just activate the base safety zone alarm. What if Maya wants to go out to see the snowscape at night and steps on it by accident? A broken leg is a minor issue, but getting killed is a major one.
We don't have to worry about wolves, and even less about zombies. Zombies have their active areas, and it takes a process to deviate from those areas, they can't reach the base safety zone in a single night. Unless the safety zone itself is within their active area.
Maya crawled back into her sleeping bag and continued tearing at the meat: "Whether it's 99, 88, or 77, all the routes we've taken are desolate. We only encountered the Cloud Dream tribe on Highway 88 because of a broken bridge, and even then, the Cloud Dream tribe was far from the bridge. Traveling along Highway 77, we occasionally saw ruins left by humans. Why would there be a human settlement here?"
