I Am a Mortal, Why Should I Deliver Express Delivery to Gods?

Logistics in the three realms have been paralyzed for three hundred years. Gods rely on flying pigeons to send messages, and ghosts rely on dreams to send messages, with zero efficiency. In the entire Three Realms, there is only one courier left running. Fan Xiaoqiang, a mortal, has zero spiritual energy and it is impossible to practice. But he is wearing a courier uniform that no one dares to touch... Does the god want to silence him? Sorry, violation. The devil wants to rob him? Sorry, it's illegal. Until one day, he sent the "Amendment Page of the Book of Life and Death" sent from Heaven to Hell to the wrong place, and one of the pages should have died... Heaven wanted him to pay for his life, Hell wanted him to correct his mistake, and Dragon Palace wanted him to keep his mouth shut. Three parties are chasing a mortal courier. Fan Xiaoqiang slapped the receipt form on the table: "I am only responsible for delivery. As for who is responsible for the wrong delivery - we follow the rules... This order must be signed for by the three realms again.
