Never Tire of It

In ancient times, there was a strange book in the market that contained a spiritual dagger, and its name was Wuyan. It is more than eight inches long and less than half an inch wide. It is extremely narrow and sharp, and the king of Qin can't match it. He understands human nature, can transform into human form, is knowledgeable about the past and present, and has a clear understanding of love and hate. Because no one saw it, everyone looked at it with weird talk. After dinner, he smiled and said: "The virtues of this blade are only because they exist in heaven. How can they be seen in the world?" There was a scholar in a white robe at the table, with black hair and an ink crown, a faint smile, a man of few words, and would not answer what he heard, as if he was a god. Everyone was suspicious and looked at each other and asked: "You are not my scholar, where did you come from and where are you going?" The scholar replied: "Yu Xiao, this blade is lonely and perverse, stubborn and stubborn, so that it wanders around doing nothing all day long." Everyone was shocked: "May I ask what your surname is?" "There is no boredom, no desire to seek, no limit to fighting, and no love to match."
