The Celestial Realm consists of Nine Heavens, Cyan Celestial, Azure Celestial, Profound Celestial, and the Lower Three Realms.
Complete Heaven, Yangtian, Primordial Heaven, and the Middle Three Realms.
Vast Heaven, Jun Heaven, Emperor Heaven, the Upper Three Realms.
Normally, cultivators from the Cyan Celestial Realm ascend into the Azure Celestial Realm. Accumulating cultivation and crossing tribulation, they enter the Profound Celestial Realm.
When cultivators pass the twenty-first heavenly tribulation, they can proceed to the Complete Heaven.
The higher the realm, the stronger and more abundant the primordial energy and spiritual qi.
Cultivators in the Lower Realm generally can only open the void connection by crossing tribulation to enter the Upper Realm.
Gao Xuan's crossing tribulation is different; he has accumulated too much power, and lingering in the Lower Three Realms holds no meaning.
