The Lord of Total Distortion was observing Gu Qing Shan.
Gu Qing Shan was also observing him.
In truth, a powerful fiend or devil of the Lord of Total Distortion's level could easily take complete human form without anyone noticing any difference if he wanted to.
But he didn't change his pair of greyish-green double pupils.
The pair of double pupils almost seemed like they had some sort of magic that caused Gu Qing Shan to feel himself separating from this world itself as he stared at him.
This feeling was quite similar to his [True Soul Cleaving Eyes]
Indeed, since the War God UI was no longer here, there were quite a few Title Skills that he couldn't use anymore.
But the [True Soul Cleaving Eyes] was originally the [Iris Sword] that Gu Qing Shan slowly trained and honed to create, it was then further reinforced by the War God UI and evolved to form the Thaumaturgy.
