When Ainsley and the others left the domain, they were indeed thrown into the battlefield mid-air where countless spiral wormholes were lurking around.
However, with the Phoenix's blessing and everyone owning wings to fly, the group safely went to the Blood Clan Kingdom first.
This kingdom was not too far from the battlefield, not too far from Pandora Island and not too far from Godlif Country.
The blood clan used their power to merge many islands into one huge territory and they had been doing it in secret for so many years.
Such a huge change yet no one noticed it.
It could be said that aside from hiding underground, the blood clan also had manpower all over the world to secretly prepare their new territory.
The old kingdom was gone, and the elders personally moved the formation from their ancestors to the underground territory in their new kingdom.
