Nix’s Space Techniques
Nate followed the insect with his spiritual perception. He only retracted his spiritual power after it had flown a distance away from their camp.
What he didn't know was that there was another person who had seen this.
It was Nix.
She had seen how cautious Nate was acting when he entered his tent. She even felt the spiritual perception that he had released to observe the surroundings. If it weren't for the space technique that she had mastered, Nate would have discovered her by now.
She had a high mastery in space techniques. One of the techniques she mastered was a concealing skill called Dimensional Concealment. It could hide her presence and aura. This was what she used to hide from Nate's spiritual perception.
