Chapter 425: Exploration × Information gap × Challengers
There seemed to be no danger in the pitch-black space apart from the darkness itself. Joey and the others had made their way through practically unimpeded.
The only problem was that more and more things were following them.
But these things seemed interested only in observing, watching and trailing them from nearby without approaching or showing any hostility.
Even when Joey and the others tried to probe them, the monsters seemed to possess some special counter-surveillance ability, retreating in an instant.
Since probing with Nen was impractical, Joey and the others could only ignore their pursuers for the time being.
They were also drawing closer to wherever the key was pointing. They felt this because a faint light had begun flashing on the key, and its flashes grew increasingly frequent as they advanced.
The surrounding buildings began to thin out, or rather, there were more ruins.
It looked as though a tornado had swept through here, scattering everything everywhere.
There were few things hiding in a place like this, though, which made their progress even smoother.
After they had continued across the ruins for over half an hour, Joey suddenly sensed a surge of Nen sweep over them from afar.
