Duan Gujin managed to break through to the Innate First Level in such a short period because he cultivated the Bone Tempering and Muscle Refining and the Undying Heart Bone.
By training both his body and Primordial Power simultaneously, he was able to quickly enhance his abilities in very little time.
However, tempering the body is one thing; it could only assist him in advancing his cultivation rapidly in the initial stages.
If Duan Gujin's cultivation of Primordial Power did not continue to make breakthroughs, his physical cultivation would be constrained within a certain realm.
Therefore, he practiced the Mad Python Boxing in the small courtyard where he lived.
Duan Gujin picked a large tree in the courtyard and moved as swiftly as a darting python, almost clinging to the trunk of that tree while rapidly maneuvering around it.
Shoo! Shoo! Shoo! Shoo! Shoo!
His speed was incredibly fast, yet the large tree showed no sign of shaking.
