In this chapter, we learn that Lin Su's blood type is "rh-negative" , which means that he is from the "ghost doctor valley" . Lin Su explains that he and his wife have been working together on a project to create a "passage" between two continents. The project has failed, however, because all of the research subjects are from different parts of the world, but Lin Su has succeeded in creating a passage between the two worlds.
