Jiang Li and the ancestor were so surprised because what they saw was none other than the cornerstone of the Scripture Storage Valley, a missing piece on the core stone monument of the Scripture Imparting Hall's ancient ruins!
More than 270 years ago, the battle for the ruins before the establishment of the Scripture Storage Valley was extremely intense.
They had destroyed the Scripture Imparting Hall, which was the core of the inheritances.
This also caused most of the cultivation methods and inheritances in the Scripture Storage Valley to be incomplete.
Only a small portion were lucky to be intact.
For example, Jiang Li's core spirit refinement cultivation method, the Great Carefree Bodhisattva Heart Sutra. The sect clearly knew how powerful this cultivation method was, and it was not inferior to or even superior to the four great inheritances of the Scripture Storage Valley.
