"This old guy..."
Yun Xiao naturally showed a strange expression, because he believed that even the Holy Rank Pulse Refining Masters of the Nine-layered Dragon Cloud here would probably be unable to find a flaw in this Poison Meridian Skill practice method, let alone Qingmu Wu, who was merely a Low-level Heavenly Poison Vein Master.
In terms of the Meridian Refining Technique, perhaps Yun Xiao was still far inferior to Qingmu Wu, but in terms of experience and understanding of the Poison Meridian Path, even a hundred Qingmu Wu couldn't catch up.
This technique was derived from the experience of countless Poison Vein Masters in the Nine-layered Dragon Cloud. It had been refined over time, and Yun Xiao was already looking forward to Qingmu Wu's upcoming expression.
Upon seeing Yun Xiao's expression, Liu Hanyi couldn't help but feel relieved, and Mo Qing, nearby, stared intently at Qingmu Wu's old face, with a similar kind of anticipation as Yun Xiao.
