บท 1214: Cultivation Breakthrough!

Ace was surprised to see this prompt and asked with a frown, "Why would I need to spend 10 million TP to integrate spirit fire with my cultivation heart? Couldn't I do it myself like everyone else?"

Ace's question was reasonable because he knew how cultivators absorb and integrate spirit fire with their own foundation. It was fairly simple since all one needed to do was accept the spirit fire into their inner space and then let it integrate with their cultivation foundation as long as the spirit fire couldn't overwhelm them.

Furthermore, this Demonic Black Spirit Fire wasn't naturally born. It was still in its seed state, the earliest growth stage of spirit fire, which means it didn't have its own intent or spirituality yet. Spirit fire seeds were the easiest and most gentle to integrate, and cultivators actually preferred spirit fire seeds to mature ones.
