Countless strands of Internal Breath that were as thin as gossamer flowed through Chu Nan's entire body and spread throughout all his meridians. His dantian was densely packed and continuously transformed with the two star clouds in his dantian.
While transforming his Internal Breath into spatial energy through these star clouds to control the spatial energy outside, he could also see strands of spatial energy entering the star clouds. At the same time, they produced his Internal Breath and flowed back to his dantian to join the Internal Breath circulation in Chu Nan's body.
Internal Breath transformed into spatial energy through the star cloud. This was the most basic use that Heaven Control Martial Artists could achieve by using the star cloud. However, almost no Heaven Control Martial Artist would transform spatial energy into Internal Breath.
Or more accurately, no Heaven Control Martial Artist would think of doing this.
