Deep within, a gigantic void passage was instantly opened, traversing the time-space barrier of the Spirit Ruins Realm and connecting to another Great Thousand World, that being the Ten Thousand Demons Realm.
The so-called Ten Thousand Demons Realm is actually the true headquarters of the Demon Race in the Mortal World.
This Great Thousand World nurtured countless powerful demons, with an unknown number of upper-tier demons residing within it. As long as the Ten Thousand Demons Realm remains intact, the Demon Race will never fear mortal cultivators.
However, the location of the Ten Thousand Demons Realm is exceptionally secretive.
To this day, apart from demons, no one knows where the Ten Thousand Demons Realm truly is.
Whoosh! Whoosh! Whoosh!!!
The next moment, one after another Mahayana demon instantly flew out from the depths of this void passage.
