By means of literature and logic analysis, this paper analyzes the "images of violence" in Kong Yiji written by Lu Xun from the perspective of culture and literature, and explores its "essence". It is believed that Kong Yiji's ideological corruption, loneliness, negative mentality, extreme weakness, and passive resistance are the inevitable causes of his "images of violence". "Ignorance and lack of guts" and lack of martial spirit is the essence of this character. This paper provides the way to treat "literati of Kong Yiji type" who lack of martial spirit by employing "Weiwu scriptures" in the cultivation which includes morality, perseverance and optimism, enterprising spirit and self-improvement. Finally, the paper proposes that "Kong" should be an alert in the new period to "literati of Kong Yiji type" who lack martial spirit.
