These days, Ye Xuan studied the Primal Chaos Heaven Refining Art. Although he had successfully activated it and met the cultivation conditions, it wasn't easy to completely master this divine-grade cultivation technique.
Even the current Mo Jianming, who had been cultivating a partial divine-grade cultivation technique for a hundred years, could only be said to have half-succeeded, let alone this divine-grade cultivation technique.
The more he studied it, the more he could feel the power system within it. It was different from the current cultivation methods and could be said to be unheard of. Even if it had been lost, it did not affect its power.
Ye Xuan was sure that even in ancient times when there were plenty of rare treasures and spiritual energy, the Primal Chaos Heaven Refining Art was still a rare and extremely precious cultivation technique.
