Indeed, he sensed the aura of lifespan from this pill.

This cannot be refined through essence blood. After absorbing the Yin Yang Technique from the Ximen Family, he became more convinced of his standpoint.

He looked at Huang Yuan and asked, "Where did you get this pill?"
Huang Yuan glanced at Li Nuo and said, "A mysterious alchemist…"
He dared not say more; this was a matter between father and son, and he dared not interfere.
Li Nuo looked at Dongfang Xuan and asked, "What did you see?"
