Demonic blood, hearts and souls poured into Xinzi like a flood of foul commodities, filling his entire being with astronomical levels of energy. Once more, Dao Foundation, fleshly body and soul feasted on premium nutrients, improving at an astonishing pace as Xinzi breathed in and out.
The faces of the 666,666 Heart Demons shifted in Xinzi's mind. Their emotions, ambitions, desires, all that ever represented them, burning in his soul.
Over half a million individual personas, wiped out in a single move and consumed till nothing stayed behind.
Well, not really. Their thoughts and emotions would remain, buried in Xinzi's soul. They weren't dead, just transitioning into particles of a new entity, or so Xinzi thought, at least.
The average Heart Demons, those that typically took shape in a straying cultivator's heart, were born and bred from insecurities, vices, and corruption. These dark emotions now acted as fuel for Xinzi's Bloodshifter Heart and Evil Qi.
