Xuanyangzi was supposed to take the place of Shang Yunfeng to handle affairs in the secular world, which included searching for various cultivation materials, and the dragon-qi girl was one of them.

Shang Yunfeng's strength was among the very top of the Ten Confusions, second only to the Demon Lord, ranking as one of the Eight Heavenly Demons.
