[Border Purgatory].
Ji Jue knew this word—Limbus, also known as Spirit Register Prison. In mythological fragments from before the Chaos Era, it was the outermost edge of Hell, the place where the unbaptized went after death.
However, religious scholars still debated whether it was truly part of Hell.
Though it belonged to Hell, those who lived there suffered no punishment. Yet if it was not Hell, it was not the human world either, and as an afterlife, it had nothing to do with Heaven.
So, if one had to put it bluntly, it was more like an ambiguous disputed borderland, a transitional stage in the journey from the human world to Hell.
A quarantine zone, eternally storing all manner of miscellaneous things that could not yet be distinguished or defined.
And that was the purpose of the [Border Purgatory Layer] at the center of the Sky Rail.
"Just as you guessed, since the Sky Rail has drawn upon Shadow Sun's power, it is inevitably subject to corrosion... But everyone agreed that such a small price was completely okay."
Ji Jue waved his hand vigorously.
"So, a special area was designated as a firewall and quarantine zone to prevent the contamination from spreading." Within the ruined mural, the lantern-bearing dispatcher gave a low chuckle. "Over the years, quite a lot has accumulated, though much of it will dissipate on its own if left alone. Recently, however, because of the Established Law's operation, a few more drifting objects have been spewing out of the [Well]... So, as a temp worker, you'll start here!"
The big-eared creature brayed, "Wer wer!"
"Mm, in any case, it's better to build up some experience first than to go head-to-head with Worm from the beginning." The dispatcher nodded repeatedly. "Surely you understand my painstaking intentions now, right?"
