Blood Exchange?
Those in the Blood Exchange Realm could never enter Xunmu Cave Heaven.
This was something the Dragonwood Island Master was very certain of. For over a thousand years, the occupants of Tingchao Cliff had occupied Xunmu Cave Heaven, trying various methods, including suppressing one's realm, concealing one's aura, and even temporarily sealing one's Yuan Gang with special means. Yet no matter the method, it was impossible to allow experts in the Blood Exchange Realm entrance to Xunmu Cave Heaven.
The biggest problem was that after breaking through the Mysterious Pass in the Marrow Cleansing Realm, although the interaction with the Power of Heaven and Earth was also profound, their Martial Bodies had not yet reached the state of Perfection, had not yet achieved the true 'Unity with Heaven and Earth.'
