'However, if this enormous vine lifeform could erase the Will of this Yin Essence... Then it's at least at the Low-Level of Eighth Stage...' Davis smiled with little confidence.
Even if it was higher by two levels, he felt that he could still kill it using Fallen Heaven, however, if it were to follow the same cultivation system of a magical beast and possess a soul that is at the Eighth Stage, he felt that he would be perhaps sacrificing a huge portion of his soul essence to kill it!
An Eighth Stage Magical Beast's Soul was equivalent to an Eighth Stage Soul Forging Cultivator! Unlike these existences, the Eighth Stage Experts he enslaved had their souls at the Elder Soul Stage, the Fifth Stage in Soul Forging Cultivation.
But then again, this particular Yin Essence suppressed the soul, the same as Lightning!
Would it require more soul essence for him to kill it with Fallen Heaven?
