A woman screamed when she saw the veteran stab at the man's neck, causing him to die immediately.
The guard saw what the veteran did. He understood immediately and started to kill the wounded people without mercy.
"Are you crazy?" asked the nurse. Due to the ethics of her profession, she could not bear seeing them killing wounded people in front of her.
"At a time like this, however, if they don't kill those people, they will turn into zombies and we all will die in the end," the university student explained.
"Apart from that, we have to hurry now. You go and help the boy think about what we will use to kill those zombies," said the veteran.
“I'll watch your back. Maybe some of them are hiding the bite wounds or scratches. We have to be careful first," said the guard.
Bang! Bang! Bang!
The banging of the iron door of the rooftop sounded, together with raspy moans. Thus, everyone on the rooftop knew immediately that the zombies were coming to the rooftop.
