"Very good. Use the Exterminating Heart Technique first, then adjust it from the Exterminating Heart Technique to the Giant Rock Turtle Breath Technique. Experience the difference in spatial energy fluctuations."
The reason why Chu Nan chose this Giant Rock Turtle Breath internal cultivation method was because the characteristics of this cultivation method would slightly decrease the activity of the spatial energy controlled by the cultivation method under normal circumstances, but it was still within the range that most ordinary martial artists could sense and control.
