Zhang Zhen
Li Huai is the illegitimate son of Li Manqing, an influential government official who is also well versed in martial arts. His grandfather, Li Xunhuan, was a highly revered martial artist who rose to fame for his signature dagger-throwing technique, the "Little Li Flying Dagger". Li Huai has never met his father before because he was raised far away from home by his mother, who died when he was still a child. He leads the life of a roaming street urchin with his two best friends, Zhao Chuan and Zhang Zhen.
