Two minutes later, Gleipnir had more or less understood the map layout of Modern City.
Angel had divided the surface of Modern City into six rings.
The center was the First Ring; the closer an area was to the First Ring, the more prosperous it was.
Beyond the Fourth Ring, high-rise buildings had already begun to thin out. The Fifth and Sixth Rings were all kinds of ruin zones and slums.
However, Modern City actually had a hidden Negative First Ring, or rather, a "Seventh Ring"—its extensive sewers.
The sewers were filthy, but many people lived there. There were even some underground streets that looked quite bustling.
Those sewers, which stretched in every direction, were the "Seventh Ring" Angel spoke of.
The area where Gleipnir and Star Worm currently were lay at the border between the Fifth and Fourth Rings.
They were in the Fifth Ring, while the buildings beyond the high wall surrounding the ruin zone were part of the Fourth Ring.
"Which ring is Prada Media Company in?" Gleipnir asked.
Angel said, "The Fourth Ring. But although it's in the Fourth Ring, it's still quite a distance from the ruin zone where you are."
They were in the southwest, while Prada Media Company was in the northwest.
If they traveled straight across, they would even have to pass through the Third and Second Rings to get there.
