The Apocalypse Broke Out, My Classmates Begged Me to Lock the Door for Help

[Apocalyptic zombies + no system cheats + cold-blooded and ruthless + single female protagonist] Influenza outbreak in early July 2036 In a high school dormitory near Jiangcheng, people were sitting around a steaming hot pot. "Hey, this pot sells well! I ate it for a long time without being caught." At this time, the dormitory door was kicked open by a flying kick. "Check your bed! Hand over all your things to me." "6. Can the director give me a way to survive?" "A way to survive? Yes, no problem." The doomsday broke out the next day, but the four protagonists were fined for violating school rules and escaped by sweeping the dormitory floor. The four looked at the chaotic scene outside and discussed "Brother Nan, we have the key now, and the dormitory is so safe. Can we gather the people to unite the people and escape from death?" But then I saw the protagonist wave his hand and say with a righteous face as if he was a savior. "Everyone follow me to the door! Then..." "Lock the door!!!"
