Qin Mu controlled numerous jade scrolls to fly around the jade pillar and the runes on the jade scrolls projected themselves into the jade pillar to form the shape of a youth. As the jade scrolls moved, the youth in the jade pillar also slowly turned his body as well.
Qin Mu could clearly see the internal structure of this youth's head as well as the internal structure of all kinds of organs.
Qin Mu shifted the position of those jade scrolls and he could even see magnify the organs of the youth's body and examine even finer structures.
This youth was Celestial Venerable Yu.
Qin Mu stood in front of the jade pillar and carefully examined the Celestial Venerable Yu that was in the pillar. The Celestial Venerable Yu projected out by the jade scrolls gave him a wrong feeling.
