When they traveled across planes, they would establish a river with the Blood Bone Beasts' blood, and have the souls of the Blood Bone Beast push them forward. It was similar to the Noscent mages' Planar Path.
Because they were moving towards the underground world, which was full of power of darkness, it was unnecessary to control the direction. This was the nearest place to the underground world. They could float there naturally.
The river of blood was still running, and Lin Yun's spells were continuing. He didn't have to use spells to control them, but he just wanted to play it safe.
After a dozen minutes, a glimmer of light appeared ahead, as if a firefly was floating on the surface of the bloody river. As they drew closer and closer, the light became dazzling, and seemed to be tearing the darkness apart.
The boat dashed towards the light. Instantly, all the darkness was gone. The sky was glowing, and everything became bright.
