Xukong's words made the cogs in Lin Mu's brain turn and everything started to link up; the culprits hiding in caves, them disappearing easily, the kidnapping of the mercenaries, the presences of caves everywhere in the region of which nearly no one seemed to have knowledge of.
Lin Mu then looked at all the runes that had been carved into the walls and realized that all of this should have been ancient and have been exiting here for countless years. He then realized one of the most important things.
It seemed too suspicious that barely anyone knew about the caves. At least the people who took care of the wells in the city should have known of them, and if they knew then normal people should have found out about it as well.
