If one prostrated on the ground and looked at Jing Jiu's feet, they would find that the bottoms of Jing Jiu's shoes actually didn't touch the ground.
As the Underworld Emperor pointed with his finger at the bottom of Jing Jiu's feet, Jing Jiu realized that he was floating above the ground. Jing Jiu landed on the ground, and his body suddenly became shorter.
It was then that Jing Jiu had more of an existential feel, though the fairy aura was still with him. The only difference was that he didn't feel like he was un-rooted anymore.
As Jing Jiu looked at the Underworld Emperor, he also discovered the bodily changes on the Underworld Emperor.
The Underworld Emperor's energy became stronger, and his black jewel-like pupils were more peaceful. His facial skin was pale as usual but not as transparent as before.
