The gray matter of the Netherworld Star is a treasure hard to find in the Yang Realm.
Some cultivators who practice heterodox paths are especially fond of such things.
This item is a specialty of the Netherworld Star, formed by the evaporation of a liquid from the star.
That liquid is the Netherworld Water from the Underworld.
As for how this extremely Yin Netherworld Water came to the Netherworld Star and transformed this star domain into what it is now, it's impossible to ascertain.
Long Fei's Witch God Banner aims to refine powerful Witch God Banner Spirits, and the gray mist on the Netherworld Star is the best nourishment.
This Yin Malevolence Qi, which has taken billions of years to form, continuously swirls and gathers on the entire planet, endlessly devoured by the Witch God Banner in the outer space.
The beings born and nurtured on this planet all have an affinity, crying out towards the sky.
