I am Wang Sansheng. My name is taken from an ancient saying: "I examine myself three times in a day." I am an ordinary delivery person in the "grey era". But I am special because I am a delivery boy in Tucheng. The mayor of Tucheng has been invaded by beasts all year round, and there are not many auxiliary cities left. Even the main city is occasionally invaded by monsters. As a deliveryman who can run around in this era, what kind of ordinary person would I be? It's just that many people in this world don't realize this. I heard that monster attacks have inexplicably increased recently. I will no longer hide myself...
