Wanyu Yuedan is the 43rd young master of Biluo Palace (Palace of Jade), located in the snowy mountains. The palace is surrounded by freezing snow. It's difficult for outsiders to reach his palace, let alone meet him. He is the leader of the third most powerful force in the jianghu martial arts world. He is a young ruler and a heaven-worshipping priest. He also leads the Wanyu family, a clan of dragon protectors. He is a 17-year-old nearly blind youth who always wears a blindfold to cover his eyes. Despite his gentle, calm, and fragile appearance, he is actually a shrewd, manipulative figure who controls situations from behind the scenes, often described as a wolf in sheep's clothing. Although not skilled in physical martial arts, he protects himself with hidden weapons and uses poison hidden in his clothing.
