"The Emergence of The Blood Clan Kingdom"

Because Atherton was afraid that there would be something wrong, Atherton and Lucifer also quickly closed down the domain. 

The demons returned to the Hell Gate, the Underworld Gate slowly disappeared, and the blood clan's ancestors also returned to the castle and became a drop of blood once more. 

After that, the demon lords left their mediums one by one without leaving any greetings because time was short, and everyone just wanted to leave the domain before any unforeseen situation happened again. 

Ainsley and the others, including the three dragons and the survivor from the blood clan were gathered in one simple blood barrier that Ainsley created so that everyone wouldn't be separated when leaving the domain. 

The domain soon became transparent, not shattering into sparkles or something. 

Maybe Atherton used this method instead of the usual 'effect' to avoid scaring the survivors of the time and space storm inside the domain.
