After Xu Qingtong returned to Cloudsky Peak, he went straight to Du Siwen's residence. He collected the other materials for refining his incarnation from her and gave his senior sister a few instructions before returning to his own cave abode.

Xu Qingtong pondered it over and over, then began using the Primordial Spirit Transformation Method to simulate the refinement within his Niwang Palace.
This was an entirely new test, and Xu Qingtong had no experience whatsoever. In particular, he had never tried combining elixir refinement with artifact refining.
