On the Night When the Apocalypse Broke Out, I Was Delivering Express at the Flight Attendant's House

The night the apocalypse broke out, the recipient of the last order I sent was a flight attendant who had just finished her flight. She politely said, "Thank you for your hard work." The next second, someone was bitten in the corridor. I am a courier who has never been in a fight in my whole life. That night I took a kitchen knife and knocked down the first red eye in her living room. Others rely on systems and supernatural powers to survive in the end of the world, but I rely on this - I am familiar with every alley in this city. Which supermarket has a back door, which neighborhood has low walls, which road is not blocked in the middle of the night, all are in my mind. I have been delivering express delivery for three years, knocking on thousands of doors and meeting all kinds of people. I didn't expect that the people who would follow me to survive in the apocalypse would also be a group of "old acquaintances"—— A hard-spoken and soft-hearted bar singer was picked up at the back door of the supermarket. She said she had never seen this scene before, but she was so frightened that she turned the spatula into a murder weapon while working the night shift; A crying little nurse was picked up from a community hospital. She is usually less courageous than Sesame, but when it comes to dealing with wounds, her hands are steadier than anyone else's; The female teacher who was rescued at the school gate had her glasses broken, but she was still protecting three students behind her; There is also the marketing manager who was trapped in the office building. Before the apocalypse, she signed for the express delivery without even looking at me. After the apocalypse, she used her account book to calculate supplies with me. She did the calculations in the middle of the night and said, "You... Seem to be quite reliable." It's also troublesome at night. Those delivering medicine, those delivering water, and those asking about tomorrow's route all took turns knocking on my door, each with more serious reasons than the last. I asked them what they wanted from me. I was just a courier. They said: I just want you to look back and say this every time you go out - "Wait until I come back."
