The body of Gao Xuan was naturally strong in muscles and bones, but due to poor living conditions since childhood, he's endured wind and cold, and consumed countless harmful things.
Practicing the Thirteen Grand Protectors' Cross Training Method without appropriate medicinal support has severely worn down his body.
The heart, liver, and stomach have all worn down and aged, as if in the state of a person in their forties or fifties.
Through the Qi Blood Power of the Snake Pearl, it unblocks the acupoints, stimulating the rebirth of organs, strengthening the muscles and bones, and reinforcing the skin and flesh externally...
This is equivalent to reshaping the body with Qi Blood Power, renewing all the damaged and worn organs. This is also the brilliance of the Body Refining Technique.
However, Gao Xuan's approach is too radical. If the vast Qi Blood Power of the Snake Pearl is not guided properly, it will lead to a burst body and death.
