Delivery boy Shen Lang broke his phone on a rainy night, but accidentally bound it to the "Wanjie Delivery System". From then on, his orders were no longer limited to the human world - delivering fried chicken to the King of Hell, buying spicy sticks for Sun Wukong, and running errands to buy milk tea for the ancestor who cultivated immortality. He thought he was just running errands to earn merit, until he discovered that every time he completed an order from another world, he would receive random rewards from all the worlds: the King of Hell's soul-enchanting pen, Sun Wukong's hair, the ancestor's body-tempering pill... When in reality, the oppression of wealthy families and the plots of enemies came one after another, Shen Lang silently took out the "bad review" weapons from all the worlds.
