Bab 139: Chapter 139 - Rescue Mission Part 1

"However, water holes can never be found from the normal route through the dungeon... Monsters are born in the deepest part of the cave and act towards the entrance, so if you go in the opposite direction, they will be found at the end of the route. Teams that don't have a structured map will send scouts to check where they are going, but sometimes they go the wrong way and turn around and be found. That's why once you advance to the previous branch, go back to the entrance of this hierarchy and look for the branch."

Follow Nami once to the intersection ahead and start back down the path you came on. When you come back like this, you're looking for a branching route that catches your eye... Hmmm... After all, there's too much we don't know...

"This is it... here it is."
