A former book king who sticks to his job of "delivering express delivery" in a fantasy world. He originally wanted to make a living by running errands, but unexpectedly received a "coffin order" and found that it contained a girl who would perish in the future. From then on, he was forced to repeatedly jump between "delivering on time" and "saving the world." Customer: "Courier, please save people on the way!" Lin Fan: "No delivery! You will have to pay extra for work other than your own job!"
