Yi Long, whose real name is Liu Xingjun, 1987, is from Dezhou, Shandong. Because of his passion for martial arts novels, my father told martial arts stories to Yi Long and his sister since childhood. My sister listened, but Yi Long believed them. His father promised that "when you grow up, I will take you to XX Mountain to find a master of XX", which was his initial imagination of "Wulin". Yi Long's sister Liu Can used to be a judo player in the local sports school. She comes back from practicing movements every day, and Yi Long is the object of sparring. Therefore, her elder sister was also the first teacher on the martial arts road of Yilong.
