Jiang Yi and Qi Qingchen had 'accidentally' found a Demon-Killing Pearl. Both of them were beyond excited. There were many treasures inside the Demon-Killing Palace. There were even Primordial Spiritual Treasures in there.
How many Primordial Spiritual Treasures were there in such a big Earth Domain?
Three!
These three Primordial Spiritual Treasures were not attack- or defense-types. They were all support-type treasures. Take the Earth Emanations Sovereign's Heaven Soul Clock for example. It sounded powerful, but all it did was boost his soul. This made his own soul spirit attacks much more powerful. Unfortunately, the Earth Emanations Sovereign's soul spirit attacks were not that strong. That was why this thing did not do much to help him!
