In "The Sword Line in the Snow", the old man with the most shots is Li Chungang, and his acting skills are very good, at first he was very proud and looked down on Xu Fengnian, but later he actually found Xu Fengnian to inherit his own kendo, Xu Fengnian did not learn swords, but learned swords, why did Li Chungang choose him? This actually depends on Xu Fengnian's talent, Li Chungang is the world's most extraordinary sword god, he himself is extraordinary, did not expect Xu Fengnian to be more powerful than him, just at the beginning Li Chungang taught Xu Fengnian walnuts, casually said two introductory things, Xu Fengnian did not understand at first, after practicing for a long time, actually knew the trick, Li Chungang also sighed at that time: "I was almost the same as I was then."

After Xu Fengnian was injured by the hehe girl in Qingzhou, he was bound to die, Li Chungang wanted to take him away from the big yellow court, but he insisted on absorbing the big yellow court, from this time, Li Chungang began to admire Xu Fengnian's tenacity, and then taught him the ultimate learning of the two-sleeved green snake. When he arrived at Xuanyuan's house, Xu Fengnian actually did not accept Xuanyuan Jingcheng's martial arts experience, and Li Chungang knew that he was open-minded and would not be easily confused by foreign objects.
After that, Xu Fengnian used two sleeves of green snakes several times, but it was not perfect, Li Chungang was criticizing him on the surface, but in fact he was secretly happy, after all, the two-sleeved green snakes that he had been practicing for many years could actually be understood by Xu Fengnian so quickly, which was not easy!
