Damien impassively scanned his surroundings with scrutiny. Although the Sky Stealer didn't appear after the Prosperity Law Monolith was shattered, nor could he sense the Heaven's Stealer's presence, he first wanted to make sure that his target wasn't here before searching the entire PHW King Sect.
The Prosperity Elders have a dense aura of sin around them, and Damien wasn't surprised because they had all lived for thousands of years, and people of their status have committed all kinds of sins to reach their current position. It was the norm of the Cultivation World.
But what Damien was looking for was the Sin Aura of Theft, and those Prosperity Elders also have it because they had stolen from others in their lifetime, like fortuitous encounters, treasures, or their secrets. However, the Sin Aura of Theft on them wasn't enough to arouse Damien's scrutiny.
