What's the Use of Being Able to Cultivate Immortality?

Lin Dong: Do you know what the highest level of swordsmanship is? Junior Brother: Hurry. Lin Dong: Wrong! Junior Brother: Benefit? Lin Dong: Wrong again! Junior Brother: Yes! Lin Dong: Not bad! Junior Brother: I don't know, Senior Brother, tell me. Lin Dong raised his head and looked at the sky, and his right hand turned into a sword finger: Junior brother, listen carefully, the highest state of swordsmanship can only be said in one word. Junior brother: Senior brother, don't be so secretive, just tell me quickly. Lin Dong: In one word: Handsome! Two words may be said: forced style. Only by forcing yourself to be full is the highest state of swordsmanship. The ten-year-old junior brother suddenly became enlightened, his eyes were filled with stars, and he ran away with a cry: Senior Brother Lin is great! He even knows the art of swordsmanship! Lin Dong looked at his junior brother who was walking away and felt something was wrong. He quickly chased after him and shouted: "Junior brother!" I don't know how to do kendo, I'm bragging!
