Yunshan County.
Li Xuan watched Meng Chong diligently practicing Martial Arts cultivation and could perceive every day that Meng Chong's physical body was becoming stronger. He was extremely satisfied inside.
"Meng Chong's physique is getting stronger. It won't be long before he can refine the copper bones, and refining the golden bones should pose no problem for him.
"Refining the Diamond Glass Bones, however, will be somewhat challenging."
When Xu Yan was practicing, the Cultivation Technique he transmitted was made up after all, with no actual technique for reference, relying solely on Xu Yan's own imagination to perfect it.
Thus, the difficulty of cultivation was naturally higher for Xu Yan.
Xu Yan managed to refine jade bones through fighting a Fire-Maned Wolf, using this challenge to breakthrough the shackles and achieve the refinement.
Meng Chong would likely need to pressurize himself and break through limitations to refine the Diamond Glass Bones.
