I Rely on Express Delivery to Communicate with Other Worlds

Lin Ran was once selected by the system to travel through thousands of worlds to complete tasks. He takes the place of the male protagonists of those worlds and fulfills the established rules. For example, a poor boy turns into a wealthy CEO, or a down-and-out young master from a wealthy family becomes a god-level strongman that no one can match. And so on, many, many, he has experienced too much life. Due to system requirements, Lin Ran maintained the stability of those worlds over and over again. Now that he is back to his original place, he also wants to use his kind ability to contribute to the place that gave birth to him. This novel and its characters are purely fictitious.
