Soul Formation Stage Heavenly Tribulation (1)

Ten years later, in the Upper Realm, stood the Two Realms Great Wall.

The term "Two Realms Great Wall" referred to the boundary between the Upper Realm and the land of chaos.

Crossing the Great Wall meant leaving the Upper Realm and venturing into the chaos-filled expanse.

Due to its unique geographical position, the Three Upper Realm Sects dispatched an Ethereal Stage expert from each sect every five hundred years to guard this place.

The Three Upper Realm Sects held their name not only due to their formidable power but also because they shouldered the responsibility of upholding order in the Upper Realm.

For instance, on the colossal expanse of the Two Realms Great Wall, whether the apex combatants or the core forces, they predominantly consisted of disciples from the Three Upper Realm Sects.
