Ning Zhuo occasionally moved behind Ning Chen or Ning Yong, placing his hand on their backs to help guide the Sharp Advancing Needles in opening new meridians.
Since both were lower in cultivation than Ning Zhuo, many of their meridians were still blocked.
Having already reached the third level's peak and recently breaking through to the fourth level, Ning Zhuo was thoroughly familiar with these meridians, like a local guiding outsiders through the path.
The Ice Light Strong Vein Talisman worked ingeniously in tandem with the Sharp Advancing Needles.
Newly opened meridians were still weak and unstable; applying the Ice Light Strong Vein Talisman immediately afterward helped solidify them, saving cultivators much effort in nurturing and conditioning afterward.
Soon, Ning Chen and Ning Yong each made breakthroughs!
Ning Zhuo constantly observed and offered guidance.
At first, Ning Chen and Ning Yong found it difficult to adapt to the new spiritual energy pathways.
But Ning Zhuo secretly manipulated the Life-Hanging Thread, directly guiding their bodies, adjusting their breathing, and continually refining their rhythm.
