While Ajax was fighting with the Darkfire Wraiths, he suddenly had a thought, 'Since this is a world, it will also have a world core, right?'
So, finally, when the fight was finished, Ajax wanted to check whether it was possible to extract the world cores from the worlds in the Dark Region.
'Ding,
The host needs to kill all the inhabitants of this world to enter the Core Realm of the World.
Once he saw the system notification, Ajax was excited because it was possible to extract the world cores from these Dark Region worlds.
Even though he could not extract the world core right away, Ajax can do it once he takes care of all the inhabitants.
Extracting the world cores was the same for the other worlds where he had to kill all the inhabitants and then his consciousness could enter the World's Core Realm to extract the world core.
