Keyong Li

李 克用

A member of the Shatuo tribe, he was granted the surname Li and the title of Prince of Jin for his outstanding military achievements. The first season mentions his obsession with martial arts, leading him to seclude himself for cultivation and neglecting political affairs. He officially debuts in the second season. His skill surpasses that of the Thirteen Protectors. His strength is unfathomable, second only to "Bu Liang Shuai." (Source: Baidu Baike, translated)
