Gravis didn't immediately consume the corpse since that would waste some of its power. After all, he wasn't at his peak. He first needed to regenerate to his current peak so that he could transform into lightning without his Realm falling further. That would only take around two hours.
Whoooop!
Yet, Gravis also didn't want to just let the corpse lay there. Because of that, he summoned it into his Spirit Space. His Spirit Space was quite massive by now, but he still needed to fold the corpse so that it actually fit inside. His Spirit Space had a width of two kilometers, enough for the corpse to fit but not enough for it to lay stretched out.
"Where did the corpse go?" the Red King asked as he flew over to Gravis.
Gravis furrowed his brows. He hadn't forgotten about the Red King, but he was still angry that the Red King looked at him like he was a commodity.
