Wuxian is a powerful and enigmatic spirit master in The Legend of Hei franchise, best known as the mentor of Luo Xiao Hei. First introduced in the 2019 film, he starts as a cold, seemingly antagonistic figure but gradually reveals a dry-witted, kind-hearted, and deeply principled nature. As an executor of the spirit realm, he wields immense control over metal and spatial abilities, often using a flying sword as his primary weapon. In The Legend of Hei 2, he continues training Xiao Hei while reuniting with his senior disciple, Lu Ye, to investigate the Liushi Guild incident. Despite his stoic exterior, Wuxian has a soft spot for stray cats—both literal and metaphorical.
