The reason cultivators of the Void Realm can undergo such a transformation is because they fuse with their own life-bound artifact.
Life-bound artifacts are taken from heaven and earth, and refining them signifies the beginning of a person's integration with the vast cosmos. Once one breaks into the Void Realm, it signifies that the cultivator has truly transcended the realm of 'man' and become an Immortal capable of controlling a domain.
Of course, finding one's life-bound artifact is like searching for a needle in a haystack, and fusing and refining it is even more challenging.
The Heavenly Dao does not easily accept those Immortals who attempt to rival it. During the long refining process, countless celestial tribulations arise, causing many prodigies to fall.
Thus, every Void Realm cultivator, no matter their special constitutions, must overcome countless obstacles and defy the heavens to reach the summit.
