Lin Mo binds to a mysterious System, only to draw the attention of higher-dimensional beings who begin hunting him. As he flees, he gradually discovers that the System is no gift, but a cruel experiment tied to the survival of humanity. Some say he is a surviving Host from a parallel world, using words to preserve the last spark of civilization. Others say he is simply an ordinary writer who happened to glimpse the truth of higher dimensions. Either way, his story is worth reading to the end.
