Conquering Second Dimension Begins From Doupo

This is the story of a young man who yearns for the second dimension and wishes to be with his two-dimension wives. One day his wish also gets fulfilled but behind his time travel, there are shadows of many terrifying beings. Let's watch how he wanders through the second dimension, slowly finds the truth, fights other travelers, saves many two-dimensional heroines, and becomes the strongest person in the whole Dimension. ( Note: This is the first time for the author. So, don't mind if the novel isn't satisfactory. Also, this novel isn't for those who just do trash talks instead of really reading the book.)
