They created wooden ladders to connect to the surrounding buildings and used the same method to block the stairs and eliminate the zombies upstairs. They then established rope bridges between two buildings.
Through this method, they controlled eight surrounding buildings, with the number of survivors reaching 12. They had firearms, special equipment, medical equipment, generators, fuel, etc. In the long term, they only lacked food, and they were trying to transport soil to plant crops on the rooftop. The nearest soil was 200 meters away, and every day they sent people down by ropes, across the zombie-blocked streets, to dig soil from the park and bring it back.
Nicknamed "The Sheriff" asked everyone to follow his channel, saying if they could successfully plant crops, the police station shelter would periodically take in survivors.
