Lu Xuan's powers were at such a level that even if he had not deliberately tried to remain hidden, everyone would've simply overlooked him as long as he just stood in the crowd.
Anyone who happened to see him would naturally look elsewhere right away.
It was an incredible feat for the Heretic to be able to just detect Lu Xuan.
That one feat was enough to say just how much more powerful he was compared to the others around him.
At that moment, many people began asking amongst themselves; "Who's this guy?"
Many of them realized that they did not recognize Lu Xuan at all upon taking a good look at him.
Everyone was shocked to find that they had no idea who he was.
The handful of disciples of the Taichu Path were enraged, their faces having turned red. The sting in their gaze was unmistakable.
