If the Heaven and Earth Spiritual Qi of the Yuanwu Realm and Blood God Realm is equivalent to a lower grade Spirit Stone, then the Heaven and Earth Spiritual Qi in this Secret Realm is equivalent to a middle grade Spirit Stone.
No wonder the Spiritual Qi that just seeped out from here has made the Heaven and Earth Spiritual Qi of the Five Elements Realm dozens of times richer.
Even with Wang Ruoxie's current cultivation at the Ninth Layer of the Pocket World Realm, if he were to stay here for a closed-door cultivation, even without any treasure resources, it would be possible for him to break through to the Celestial Monarch Realm in no more than two years.
However, he also knows that in this Secret Realm, the most precious thing is not the Heaven and Earth Spiritual Qi but the legacies of those ancient powerhouses.
