According to the Old Sect Master Zou Xin, there are only seven people in the world who know the Five Elements Opera, and aside from Zhao Yu, no one else can externalize the Five Elements Qi to be visible to the naked eye. Therefore, Zhao Yu is closely watched by the Old Sect Master and Zou Nan, to the point where Hua Tuo personally taught Zhao Yu for some time.
However, what surprised Zhao Yu even more was that he discovered the Five Elements Qi you externalized was actually colorful, which meant that you possess an extremely rare pure body of Five Elements. Whereas Zhao Yu himself only possesses two types of Five Elements, Wood and Water.
