Su Chen, a modern bus driver, travels through the world of pirates and awakens to the route planning system. He does not follow the old path of fighting for hegemony, fighting monsters, and becoming the pirate king. Instead, he takes maritime public transportation infrastructure as the core and opens fixed bus routes covering the four seas, the Great Route, and the end point of Lafdru. Use a monopoly-level maritime transportation and commercial network to break the geographical barriers and shipping route monopolies that have been controlled by the world government for hundreds of years, and completely subvert the old order of the entire sea through the peaceful evolution of commerce.
