The research on Seolingwijeon (a story about a Chinese General, Xue Ren-gui) seems to be perfectly done, but in fact, it is not yet completed.
The purpose of this study is to extend the limited recognition of < Seolingwijeon > as a mere confrontation of historical consciousness and the relationship between the two sides-Korea and China and thus gain its own authority by studying the different description for the characters of Seolingwi in the < Tangxi >, < Seolingwi Leaotang saryak >, < Seoldangfoojeon >, < Jeongdong >, < Seolingwijeon >.
< Tangxi > describes Seolingwi an aspirational character and a typical evildoer involved in total defeat in the war and a corruption. After that, however, this negative images are all erased. In the < Seolingwi Leaotang saryak > the fierce battle scenes and conflicts during the rough and difficult journey called “Expedition to Leaotong” are curtailed and describes Seolingwi in the conflicts with Jangsagwi, his superior who persecuted heroine and deceived his lord for his own self interest. This aspects are also repeated in the < Jeongdong >, < Seolingwijeon >. In a vividly graphic description of “Expedition to Leaotong”, < Jeongdong > portrays Seolingwi as a perfect hero struggling over rough and rugged paths of war. But < Seolingwijeon > transcribes and reorganizes important points but follow the settings of Korean heroic novels for popular features of characters. In other words, < Seolingwijeon > takes the “biography” style from the heroic novels - unusual birth tale, full of hardships in his whole life, heavenly rescue and fictional set up “Expedition against Southern Barbarians”, which do not appear in < Tangxi >, < Seolingwi Leaotang saryak >, < Seoldangfoojeon >, < Jeongdong >.
