Little Eight told Long Dangdang that, when Ming Xi launched her attack, he couldn't feel her soul fluctuation at all for a moment.
Not being able to sense a soul fluctuation meant what? Long Dangdang knew too well; it meant that at that moment, Ming Xi was probably close to death. Why did she come back to life later? It must be because she successfully killed the bone dragon. In other words, the cost of Ming Xi's strike was likely her own life; if she hadn't been able to kill the bone dragon, would she have died?
At this moment, Ming Xi had already begun her meditation, and it wasn't a good time to interrupt. Long Dangdang suppressed his worries and quickly started meditating with his companions. It wasn't the time to ask questions; they could only wait until after everyone had rested.
