Everyone immediately began to search around the edge of the barrier for anything suspicious. With the Dark Emperor's tomb right before them, and Jun Wu Yao had said it clearly that the thing maintaining the boundary barrier should be several crystals. All they had to do was to smash them and the barrier would be broken.
It was easier said than done as it wasn't that easy to find them. They were unable to see just how big the Dark Emperor's tomb was, but as the companions walked following the edge, every single step they took measured for them a certain distance and even after walking for a long while, they still had not found any turning points, all of them still standing on just the first side of the Dark Emperor's tomb.
