Despite the intervention of the believer organizations, they were still unable to stop the spread of the disaster. In just a short month, more than half of the world had fallen.
The survivors tried to build a strong Fortress Defense line to resist the zombie attack.
All the exits of some of the city's buildings and streets were blocked, and the nearby buildings were razed to the ground.
A large amount of food was stored inside to ensure a supply of water and food, and it was transformed into a fortress to resist zombies.
&Nbsp; such a move had a decent effect and could effectively block the attacks of the human zombies.
Infected animals would fall into a state of madness, and their threat was far lower than that of humans.
This kind of modified fortress became a sanctuary for humans and was quickly promoted.
As long as there were no internal problems, they should be able to hold on for a long time until the rescue came or the crisis was resolved.
