A trace of Internal Breath flowed out of a secondary meridian and instantly scattered into thousands of even more subtle Internal Breaths. At the same time, they surged into the thousand fine meridians connected to this secondary meridian.
While surging into these thousand fine meridians, these thousands of Internal Breaths had already been adjusted to a high-frequency vibration state of different frequencies. At the same time, they carried the characteristics of the Flame of Life.
The flow of Internal Breath in more than a thousand fine meridians became much slower, but it was precisely this slow flow that allowed Internal Breath to better moisten and refine these fine meridians. Moreover, strands of it seeped out from the meridians and tempered every inch of muscle, blood vessels, and nerves around every fine meridian. It quietly and quickly made them change.
