Gu Chen, upon introspecting his own body, beheld the one hundred and eight stars that could only be perceived after reaching the perfection of the Rebirth Stage. These stars represented the vitally important one hundred and eight acupoints within the human body.
Before reaching this realm, a cultivator could not even locate these acupoints, for they lay hidden deep within the body, only to manifest themselves upon attaining the corresponding realm.
Why are Rebirth Stage and Hundred Orifices Stage cultivators acclaimed as Martial Dao Grandmasters in the Nine Provinces? It is because martial artists of the Rebirth Stage can renew their blood and marrow, undergoing transformation after transformation to continually strengthen their physique and cultivation.
The Hundred Orifices Stage, on the other hand, entails unblocking the acupoints within the body to unleash more of its latent potential, propelling oneself to surpass limitations.
