A master of martial arts who fundamentally keeps the morality of the innate goodness of man, but at same time also accepts evil. As a Servant, Shuwen's morality had deviated from the general common sense, but his humanity itself is that of a "sensible person" that esteems rationality. He does not see great difference in justice and evil, but if someone's behavior offends his rationality, he will bring swift and inevitable death. At a first glance this would seems as an act of chivalry, but since the chivalry of China is "pick up a sword out of passion", his way of thinking is the exact opposite. Rather than rational, Li Shuwen's character is something better described as being close to that of modern people. Li Shuwen was someone who simply (not purely) sought for strength, but it has been said that, in his late years, he discovered the valor of the strength of conviction, one's way of life, instead the strength of violence. He acknowledges that he is a kind of professional killer rather than a martial artist, but that is neither a self-depreciation nor a boast. Given that he often learned, often fought and often murdered in his previous life, he really does not carry any regrets or grudges.
