It was very difficult to determine an Exorcist's strength. It was impossible to tell how deep their understanding of talisman arts and mudras was or whether they had powerful Dharma artifacts on the surface.
At that moment, Sect Master Feng was using a mystic technique to probe the psyche strength of the person in front of him. Most Exorcists didn't care about their bodies but focused on cultivating their souls and minds! This was because most of them had never cultivated their souls to their bodies' limits, so they naturally didn't need to waste time on their bodies.
What powerful psyche strength. Although Sect Master Feng was secretly alarmed, he wasn't afraid.
The study of talisman techniques and mudra techniques required time. The older one was, the higher their realm was. The current generation's Heaven Master Exorcists were all over 50 years old. One's psyche grew with age.
