A trace of Internal Breath surged in his meridians.
After circulating the familiar route that had been circulated hundreds of times and entering the dantian again, the strength of this trace of Internal Breath increased by 0.141392% compared to when it had just left the dantian. The increase could be said to be minimal.
However, such a small increase was already more than twice the increase when Chu Nan cultivated the Nine Revolutions Technique for more than ten years.
This was because Chu Nan had successfully broken through to the third level of the Nine Revolutions Technique after trying to obtain the data ability. Naturally, every time he cultivated the Nine Revolutions Technique, the increase in the strength of his Internal Breath would be much greater.
