Even with the discovery of the changes in the tunnel, the group continued deeper in. At this point, they were over half a kilometre within tunnel number 5. At certain points, the tunnel no longer went in one direction but had split into junctions. The guide only knew about the path from the surface to the unexplored region but not the region itself, so he was of no help. Asher had to then rely on his psychic energy to scan the branch tunnels for the one with a higher mana concentration, greater pressure or some other clue as he believed that doing so would lead them to the destination they were aiming for.
