Previously, it housed his Mana Core in the center, the Death Core hovering around it. Then there was Nascent Energy and Devil Energy. It was like a house with several family members.
Then, the Death Core was shattered and the Death, Nascent and Devil Energy had formed the Energy Cloud.
Still with the lively Energy Cloud and the Devilish Energy he extracted from Rima, it shouldn't look so desolate and empty.
The Energy Cloud and the Devilish Energy were nowhere to be seen, and his Mana Core floated in the center. But it no longer looked pristine like before. Instead, it looked like an egg covered in countless cracks, on the verge of collapsing.
Also, there wasn't a trace of mana inside. All of it seemed to have seeped out from the cracks and disappeared.
