Gu Chen looked inward at the one hundred and eight stars within himself. These were the one hundred and eight acupoints crucial to the human body, which could only be detected upon reaching the consummation of the Transformation Realm.
Before reaching this realm, it was impossible to find the locations of these acupoints. These so-called acupoints were hidden deep within the body and only revealed themselves when one reached the corresponding realm.
The reason why Transformation Realm and Hundred Orifices Realm were referred to as grandmaster martial artists in the Nine Provinces was because martial artists in the Transformation Realm could exchange their blood and cleanse their marrow, experiencing one transformation after another, continually strengthening their physical body and cultivation.
In the Hundred Orifices Realm, the acupoints within the body were opened, unlocking more potential and breaking through new limits.
