The Master Necromancer - Vol 1 - Chapter 59

After Skraal left the house of Old Ghost, he could feel different things about this town.

This was because of the power increase on the subject of "Ghost" and his other origins. Skraal himself knows that the more you have power and knowledge in an origin, the more powerful you will feel in that origin.

Compared to the first time Skraal came here about an hour before, he right now had more "Ghost" origins and other origins, which caused him to understand his surroundings more and feel more powerful in this land.

At that time, he saw the team of Dark Energy School. Verton understood from the looks of the Skraal that he or his team had no chance to disobey or force anything on the Skraal at all.

This kind of feeling comes from the experience of a user, and it is just a hunch. Skraal himself was not radiating new energy or a powerful force for the time being.
