Taoist Master Shiyan defeated the Yin-Yang Bagua Formation created by Xiang Su's Yin-Yang Qi with just one blow. This surprised Xiang Su. Although his Yin-Yang Bagua Formation was not as strong as the extremely defensive barrier,
But it is not something that ordinary people can defeat with just one magical weapon. In order to defeat the Yin-Yang Bagua Array, Gu Yu used the sharp horn of the extremely powerful Buddha's Golden Dragon to pierce it. At this moment, Taoist Master Shiyan only relied on a whisk.
Defeating his Yin-Yang Bagua Formation is enough to show the depth of Taoist Master Shiyan's skills.
