Yang Chan watched as a disciple from the Internal Affairs Hall consulted a list in his hands, questioning the disciples from the Cyan Yuan Sect. A peculiar fluctuation emanated from the Hall disciple as a special Spirit surged forth, and he stared directly at the person he was questioning.
This power wasn't very obvious, but it gave one the feeling of being seen through. This was one of the investigative techniques the Black Dragon had told Yang Chan about before.
In fact, it wasn't just a recent development; ten thousand years ago, all the major powers possessed such investigative techniques. The most powerful of these methods, when performed by Great Divine Power Users, could review a person's past to confirm if there were any issues with them.
However, these techniques were not easy to perform and were typically reserved for important individuals.
