Great Yin Yang Sword Realm.
This is the most fertile and radiant domain in the Upper Realm, unrivaled by any other!
The previous generation Taiyin and Taiyang Sword Master swallowed the world during their last tribulation, pushing through all fronts as the strongest in the world at that time. They forcibly seized spiritual veins from all sides, drawing Earth's Qi, gathering several ninth-rank supreme spiritual veins, with countless eighth-rank supreme spiritual veins.
Numerous spiritual veins encircle this place, with the most brilliant stars and sunlight of the Great Thousand World converging here.
