The greatest likelihood was that he would be devoured by other Soul Splits and completely disappear.
The nine Soul Splits could sense each other. Even faintly, the Blood Ancestor could feel the strength of the other Soul Splits. Many of them had already surpassed him. After all, the Upper World was resource-rich, and the Bloody Demon Sect was secretly supporting them. These high-ranking individuals who had fused with Soul Splits naturally advanced rapidly in their cultivation.
Even Ge Zuo, one of the nine original elders who first mastered the Soul Split, had nurtured the Bloody Pool with the aim of finding a suitable host for the Soul Splits and Ancestral Blood, intending to devour it himself once the cultivation process was complete.
