The sliver of soul essence left behind by the Demon Lord at the time of their demise never held any spiritual awareness, nor could it bring back the true self of that formidable being.
Additionally, as the Burning World Red Lotus weakened over time, it became more delicate. Yet, it continued to exist. It seemed possible that as the Burning World Red Lotus slowly recovered, this tiny fragment of soul essence might develop its own consciousness and evolve into a completely new entity.
From Jiang Chen's point of view, however, it seemed more likely that this soul essence was simply a manifestation of karma.
