An Internal Breath surged in his meridians and quickly flowed through all the opened meridians in Chu Nan's body and returned to his dantian.
Then, this Internal Breath that had been strengthened directly flowed out of his dantian and completed the second cycle of circulation in all his meridians.
Feeling the slight pain in his meridians, Chu Nan frowned.
Did he feel it just after the second cycle?
Before this, when Chu Nan used the high circulation Internal Breath, he only let it circulate through the meridians that had been opened before he broke through the third level of the Nine Revolutions Technique. It had never entered the seven main meridians and 26 secondary meridians that had been newly opened.
This was because the meridians that he had opened up previously had long become extremely tough after being tempered by his Internal Breath for many years. They were able to endure an even stronger high-level Internal Breath.
