Yummei reveled in the new power he possessed. The densely compacted spirit energy of hundreds of hollows, and he had taken control. Battering down the minds of all the hollow that co-existed within this body had been arduous and grueling on him, but now that he held the power of them in his hands it was all worth it.
Looking down upon this town of humans, he felt a great excitement build up in him. He would massacre this place and glutton upon the souls of countless men women and children.
Let the chaos begin.
Opening his massive jaws, he released the compressed spirit energy gathered within them in a destructive red beam; the hue of blood. It struck down upon the unsuspecting residents of the town like a bolt from the heavens, and all the while it massacred them they still remained ignorant as to what caused there death.
Slaughter, bloody carnage, genocide the likes of which was unimaginable. These expressions palled in front of what Yummei did. He crushed and smashed tore flesh asunder, rained his cero down upon them. A seemingly divine angel come to enforce karmic justice, or so it would seem to the people facing this assault.
Hundreds, not thousands, he killed in minutes. Leaving there souls open and defenseless ready to be consumed and added to his own spirit energy.
A roar of epic proportions bellowed from his massive form, the form of all Gillian. That was perhaps the only irksome thing about his transformation; he was just another Gillian among thousands. No! He was not like the others, he had drive, ambition; he had a purpose.
These thoughts spurred him on, as well as any whip had ever spurred a slave into action and he gorged himself upon the souls of these unfortunates. The feeling was... the feeling was... it was a let down.
He had hoped that consuming so many of these souls at once would have filled him like nothing before, but the same emptiness held him; in fact these souls seemed to fill him less than any human soul ever had.
He couldn't fathom the meaning; surely such a grand intake of spiritual energy should have him feeling almost... almost alive. What could possibly be the reason for the lackluster effects his feast had produced? And then it hit him. His great size and increase in spiritual energy meant that human souls, that had even before tasted bitter and weak to him now gave no nourishment at all.
So he thought to himself, human souls have no effect on you now eh? That just leaves hollows. This though picked his spirits up as he had a personal vendetta aginst hollows, still hating his own kind for having been turned into one of them.
Yummei realized that he needed to go. Shinigami would definitely be on there way to eliminate him, a attack of this magnitude could not go un-noticed. And so he opened a girganta and stepped through it returning to hueco mundo.
As a Gillian he now resided beneath the Sandy plains, he lived in the forest of the Gillian. Perfect he thought, this is the perfect place for me to begin my slaughter. I shall haunt this forest and all its occupants until I have achieved my goals, I shall evolve out of this body and into a being of pure power.
