At Quasi Divine realm, one's Essence Soul would resemble the physical body of the martial artist. Flawless without impurities, they do not fear the scorching sun, heavy rains, or misfortunes. They would truly be able to break out of the restraints of one's body and roam the world, traveling everywhere!
At that point of the Essence Soul's cultivation, it would be akin to a second, non-physical body outside of the martial artist.
There was another saying in the cultivation world of one's spirit leaving them and taking form.
By leaving them, it referred to the Essence Souls exiting their bodies and taking form referred to the corporeal bodies outside of their physical self.
In the ancient era, the Quasi Divine realm was also known as the Corporeal Spirit realm.
For Quasi Divine realm beings, even if their bodies were destroyed, if they reacted fast enough and sent their Essence Souls out of their bodies, they would be able to survive!
