Feng Qi suddenly raised his hand and slapped Lin Wu across the face. Lin Wu could have dodged, but he didn't dare move. The slap sent him staggering back several steps. Feng Qi glared at him and barked, "Even if that bastard turned to dust, would that skeleton? That thing could even hurt Old Bai. How could it be any ordinary skeleton?"
"Find him! Keep looking, damn it! Spread out. If thirty li isn't enough, search a hundred. If a hundred isn't enough, search three hundred. That bastard must not get away." For some reason, a deep unease surged up in his bones, a feeling unlike anything he'd ever experienced.
Half an incense stick later, Lin Wu and the others had searched three hundred li of sea, and were so exhausted their legs were weak. They still hadn't found a trace of Xu Yi. The White-browed Daoist said coldly, "Stop searching. That fellow must have escaped. This will come back to haunt us. Lin Wu, I told you to use the Insight Mirror on him earlier. Did you lock onto him?"
Feng Qi's brows rose. "Well done, Old Bai. Ginger really does get hotter with age—you thought of everything." The Insight Mirror was a Mystical Treasure. Once it shone on someone, it locked onto them. The next time it appeared, no matter how much their cultivation had advanced or how well they concealed their aura, none of it would help.
The Insight Mirror locked onto one's life soul, the most fundamental thing of all. No matter how much one's cultivation improved or one's blood and qi transformed, the life soul couldn't be changed. Lin Wu said, "He's locked down tight. I guarantee that if that brat dares show his face again, I'll recognize him even if he's turned to ash."
