Wuxian

无限

Wuxian (无限 Wúxiàn, lit. "infinite") is Luo Xiaohei's master and the deuteragonist of The Legend of Hei. He maintains a calm demeanor and is initially perceived as cold and unsympathetic. However, his caring nature is revealed later in the film.
Wuxian is capable of manipulating all types of metal, a skill he eventually teaches to Xiaohei. Through the ability 'Devour', Wuxian can create large holes that 'devour' all surrounding objects and materials.
