Zu Feng, a young man from the Jiangnan military camp, relied on the storyteller's half-hearted formula to break into the world, and used the knife to make Shunguai jokes until he knocked over the sweet-scented osmanthus cake of the cake stall proprietress Su Wan. From then on, he practiced real swords to get rid of the Shunguai problem while guarding the cake stall to gain confidence.
He grew up from a "donkey-attacking hero" who was full of jokes to a reliable young hero who could handle things. He also married the girl who hurt him the most and loved him the most. With the knife and the sweet-scented osmanthus cake, his career and love were all fulfilled.
