"Immortal Bone?" Xu Hao's eyes flashed with a trace of confusion. Although Wang Zhong had recently educated Xu Hao about many aspects of the martial cultivation world, Xu Hao had never heard about the Immortal Bone. Moreover, there was no information regarding it in the mental treasury of knowledge he possessed.
"Is this Immortal Bone the piece of bone in your body?" Xu Hao wasn't foolish; since Elder Chen mentioned this matter, it must be related to his current condition. Therefore, the only thing Xu Hao could associate it with was the piece of bone in Elder Chen's body. This bone was called the Immortal Bone?
Elder Chen nodded with some gravity, "Yes, this is the Immortal Bone. It's normal that you don't know about it. After all, this secret has not yet been revealed. In fact, there's only so much I can tell you! The name 'Immortal Bone' is a term used by a mysterious organization to define it; we're not too clear on exactly what it is, either.
