The so-called zonal division is often divided according to the scope of the super territory's power and the range where the zombies are located.

The first layer, the seat belt, in this zone, the super territory is completely dominant, and no force can help but participate.

The second layer, the Neutral Zone, is where small territories can be established, but they need to pay tribute to the larger powers to protect their territories.

The third layer, the danger zone, is where some hard-headed people will also build territories, but they often don't end well.

The fourth layer, the forbidden zone, is a world ruled entirely by zombies, and it is very difficult, almost impossible, for humans to establish a territory.
