Once the heart-worm was gone, the soul ascended. From then on, it could no longer be called a soul, but rather a Divine Soul. Or a holy soul.
They meant the same thing anyway. The Pure Yang Realm sought by the Taoist School of cultivation referred to this very state.
In practical combat, this Realm had no particularly special effects. At most, it allowed one to exert their strength more completely, preventing basic mistakes like one's Heart and Spirit falling into chaos.
But when it came to Cultivation... that was a different story. It made one a true, natural-born prodigy. The Pure Yang Realm could incinerate any distracting thoughts or inner demons, allowing one to practice any Cultivation Technique without fear of suffering Qi deviation.
Furthermore, any future Cultivation of Heart and Spirit or soul-type Cultivation Techniques would progress at a phenomenal pace, hundreds or even thousands of times faster than an ordinary person.
This was the real, major benefit.
