Jiang Shouye is the most ordinary takeout rider in Jiangcheng. He delivers food during the day and runs orders at night. He is most afraid of timeouts and negative reviews. Until one rainy night, he received a takeaway order delivered to "No. 7 Qinghuai Lane", but that alley was demolished twenty years ago. Someone behind the door asked him softly: "Rider, why don't you come in? I've been hungry for a long time." Jiang Shouye took off his helmet and walked into the rainy night carrying the takeout box. Others thought he was delivering food, but only the demon knew that three hundred years ago, the last sword immortal in the world came back. Since then, there is a rumor in Jiangcheng: Don't place random orders late at night, because the person who comes may not be a delivery person, but a demon slayer.
