This paper is an exploration of what can be set as the interest or essence of the work flowing under the stream of the sulyugmundab. In one side of the discussion, the tokkijeon(토 끼전) to which this version belongs was too attracted to the society of the late Joseon Dynasty, and the discussion developed. It is true that this discussion played an important role in faithfully revealing the meaning of the era of the work called The tokkijeon(토끼전), to which the sulyugmundab Answer belongs. However, it is believed that one side of the study has exposed its limitations in that it has not been able to achieve a thorough exploration of what elements were used as the basis of the work to form the undercurrent of the meaning of the era of the work. In this paper, in order to solve this point, the fundamental problem in the work is the human body, and the work theory is developed. It seems that the fable novel genre itself to which this work belongs had no choice but to have an interest in the human body. In the work, situations that show different situations and perceptions of the body continue to appear. This is proof that there is no choice but to consider the body as the basis for composing the work. Although the subject discussed in this paper has certain limitations by limiting it to one version of the sulyugmundab(수륙문답), the task is to expand the subject of consideration in future discussions and to apply the results obtained in this paper to confirm what the story of the tokkijeon(토끼전) like as a whole.
