In the cave, Zeng Chengde sensed the person outside and frowned slightly.
"Just one person?"
He looked at Pan Youcheng, who immediately took a hint. With a flick of his wrist, a palm-sized mirror appeared in his palm.
As spiritual essence was injected into the mirror, ripples appeared on the surface like the surface of a lake. When it calmed down, there was a red dot the size of a grain of rice on it.
Pan Youcheng touched the mirror lightly and moved his finger left and right.
A moment later, he looked up at Zeng Chengde and said in a low voice, "There's indeed only that guy outside. His cultivation level is no more than the fifth level of the Spirit Nurturing Stage!"
A hint of surprise flashed in Zeng Chengde's eyes.
Pan Youcheng's Heavenly Eye Mirror was enough to detect everything within a five-kilometer radius. No matter what concealment methods cultivators below the Mystic Light Stage used, they wouldn't be able to hide.
