When this voice rang out, all three members of Lin Fan's group were surprised.
They turned in the direction of this voice and they found that there was a cloaked figure that was standing in the middle of the room, in between them and the old woman. This figure was completely covered in their cloak, so they couldn't see what this person looked like, but they were certain that they hadn't sensed this person until the moment this person chose to reveal themselves.
If this person had wanted to hurt them, they definitely wouldn't have noticed them until it was too late.
But as for whether this person could hurt Lin Fan and Wang Jian, that was a completely different story.
Based on the aura that came from that person, it was clear that they were only in the Low Embryo Soul Realm. However, it was a fact that they had been unable to detect this person the entire time which meant that they must have some kind of special technique for hiding.
