A Feather?

Lin Wu had not gotten the exact location of the next temple, but knowing that a specter skull hound was searching for it meant that he would be able to find it too. Plus, he knew the approximate direction that the Specter Skull hound had gone in.

But this was not all that Lin Wu had obtained from the memories of the followers of the Skull god. He learned how they operated and why they were doing what they were doing. 

The so called followers of the Skull god were nothing but cultivators that had been brainwashed by the Skull god. They would then be sent out to search for the temples of the vermilion bird and get the Bloodline crystals of the Vermillion bird from them.

Of course, finding these temples was quite hard as they were hidden deep within the ground and only occasionally would one of them pop up in the ground. Why they did, this was not known to the followers though and thus Lin Wu did not know either.
