Traveling through the late Han Dynasty, I somehow became the best swordsman in the world. Cao Cao heard about my deeds and made a special trip to visit me. As soon as we met, he called me a hero and said he wanted to learn swordsmanship from me. I thought to myself, I can't even hold a sword steady, what can I teach you? Teach you how to brag without drafting? But I couldn't reveal my secret, so I had to bite the bullet and pretend to be the superior person. Cao Cao asked me how I killed three thousand barbarians. I said: Just like that. Cao Cao asked me what I could teach him. I said: learn to run first. Later, Cao Cao really learned to run - he ran faster than anyone else in every battle.
