Li Huai's half-wit, Li Zheng, was challenged by four masters because of his young age, so he was not allowed to practice Xiao Li's flying knife again. Fortunately, his brother inherited the unique skills of his family and loved him deeply, so he was very cute in Li Huai. Li Zheng was full of jealousy, which led to a great change in his personality. He lived in calculation and mistakenly used Yan's method in his own planning, which led him to do many bad things and finally committed suicide in order not to become a demon. He is not open-minded. He knows that the party he likes doesn't like himself. When he was bluffing with others, his arm was cut off, which also led to his father Li Manqing's sudden unbearable stroke, and finally he died.
