The so-called Unity Realm refers to the process where a cultivator, after breaking through the Transformative Realm, chooses to merge their heart and Yin Spirit or some divine treasures to better withstand the heavenly tribulation during their breakthrough.

Most of the time, cultivators in the Transformative Realm choose to unify during the Shocking Heaven Realm breakthrough or directly during the Unity Realm breakthrough.

Of course, if the fortuity arrives, some Transformative Realm cultivators choose to unify during the Aspiring Heaven Realm breakthrough.

Because after unifying, they can gain the divine powers of the Yin Spirit or certain treasures.
