The Long Ferry Crossing

In this world, different dimensions exist, linked by passages known as the Youyou Ferry. An ancient boat that looks utterly ordinary can transport people or objects to another dimension. There are four dimensions in all: the Realms of Reality, Nanke, Qiongting, and Anhe. People in each dimension know the others exist, and they coexist and travel between them in peace. The wondrous Youyou Ferry connects all four dimensions, and brings together the stories of certain people as well... What kind of encounters await eight young men?
