Brother of Gongsun Wan'er, the third and fourth Chosen, a brother and sister team from Irispetal Peak.
Gongsun Yun, who excels in the Dao of bugs. He always wears a black robe, which is filled with all sorts of bugs. People even say that his body is filled with bug eggs. What a freak! He usually covers his enemies with bugs, and then has them bore into their bodies and drink their blood. The pain is so horrible that people usually just want to die. If you don’t escape quickly enough, you’ll be completely eaten up, with only your bones left behind!
