After contemplating for many years, Wang Wei decided to engrave Divine Veins not just into his Divine Altar, but also into his soul. If he succeeded, his control over spiritual qi would reach an unimaginable level and he could also guess that there would be further benefit when he entered the Primordial Spirit Realm.
However, there was still a problem that needed to be solved: How to gain access to the soul.
Only cultivators who have opened their Niwan Aperture and have their own Sea of Consciousness can have easy access to their souls. And only in the Supernatural Realm did cultivators open up their Niwan Aperture.
However, this problem was not so difficult for Wang Wei. As a person who knows how it feels like to live solely in the form of the soul, he has a great deal of understanding about it.
