Wuyao Lang

Lang Wu Yao, "Rou Fu You", (浪巫謠), is a major ally featured in Thunderbolt Fantasy Sword seekers. Wu Yao grew up in the mountains with a mother who only wanted her son to live up to the voice that he was born with. When he becomes sick, she accidentally kills herself after his voice changes. Going off on his own, he gets a job playing for a bar, using the pipa his mother played. After meeting Mu Tian Mìng, he abandons his duties as court virtuoso and joins her and Shang Bu Huan after saving them from Xiao Kuang Juan.
