The immortal who once ruled the world was born as a delivery boy in the city. He thought he could understand the new realm of heaven by delivering food, but he didn't expect that today's China is full of strong people. When delivering food, there is a fight between cultivator families, and when passing through a door, one encounters an ancient ban. Even the five-star reviews given by customers contain the soul of the devil. It wasn't until he crushed the magic weapon of the saint who came to assassinate him with one hand that the entire cultivation world was shocked to realize that this delivery boy who was criticized for being overtime every day was actually the number one immortal who killed thousands of years ago!
