Spiritual roots are divided into four grades, and most are aligned with the five elements.
First-grade Heavenly Spiritual Roots, second-grade Earthly Spiritual Roots, third-grade Mystic Spiritual Roots, and fourth-grade Yellow Spiritual Roots.
Metal, wood, water, fire, and earth.
Beyond these are a few rare variant spiritual roots: wind, thunder, light, darkness, and ice.
Chen Xiaonian possesses an attribute-less devouring spiritual root. He claims the creation of heaven and earth, devours all things, and grows stronger.
This is the story of an ordinary mortal who leaves his mountain village and cultivates from the bottom until he becomes an immortal.
You should change the title. It has absolutely nothing to do with Devouring. Are you trying to lure people in to kill them? Or is it supposed to be that the protagonist cultivates to a certain level, then dies for some reason and transmigrates into Devouring? A typical early cultivation story that could be finished in a dozen chapters has been stretched to 44!
The plot was so bad I had no desire to continue listening.
