The perspective expressed in the post was simple: the Netherworld was prevalent throughout the Human Race, so it's impossible that the Central Spirit Domain would be the only one without its presence.
There was no reason for the Demon Race to abandon the Central Spirit Domain either.
That could only mean the Netherworld in the Central Spirit Domain was still lurking.
The one that lurks in the shadows until the end often turns out to be the final boss.
Moreover, the disturbance caused by the other six domains' Netherworlds in this version seemed a bit baffling – there were no clear reasons on the surface and it seemed more like they were intentionally handing out advantages to the Human Race.
After all, in terms of overt power, where was the Netherworld a match for the Human Race?
