บท 943: Entering the Upper Three Heavens, Meeting Mu Wan Again

The Immortal Source World, once renowned as the Great Sect of Alchemy in the Upper Three Heavens, the Cloud Heaven Medicine Valley.

This was a major sect that had been famous for alchemy since the era of the Valley Divine Court. There were many alchemy mighty figures in the sect who had become Sages and even become Dao Ancestors.

The top-grade pills in the Immortal Source World, the Immortal Pills, were mostly refined by the Cloud Heaven Medicine Valley.

The Cloud Heaven Medicine Valley was also a sacred land in the Upper Three Heavens, where no major sect was allowed to conquer.

But now, things had changed.

The heavens and earth collapsed, the Nine Heavens turned into Three Heavens, and the Upper Three Heavens merged into one.

The powerful beings who resided in the Nine Heavens had all left. Even the Heavenly Venerables and Dao Ancestors had almost all departed.
