At this moment, Ye Feng instantly extended his spiritual power, covering a range of ten miles.
Ye Feng was extremely vigilant in probing the surroundings because he remembered that there shouldn't be just three Sword Intent Puppets.
Because just a moment ago, when the leader of the East Border command was ambushed by the Sword Intent Puppets, Ye Feng's eyes had briefly left the Sword Intent Puppets, which meant that the Sword Intent Puppets had left the Mirror World within his eyes, but they hadn't appeared in front of Ye Feng and his companions.
This meant that the Sword Intent Puppets could appear from anywhere at any time, so Ye Feng began his detection.
