Perhaps these caves represent different Cultivation Techniques or different domains, but because there's no clear standard, no one knows exactly what each cave stands for.
So Ling Zhenfei also didn't know which cave he should go to.
But those people just now had all flown toward the very top cave, so according to Ling Zhenfei's analysis, the higher the cave, the stronger the Cultivation Techniques inside.
Although this Wuliang Book Tower is built inside the mountain caves, it's still called a book tower.
This whole cliff full of caves is like layer after layer of bookshelves.
Each layer of "bookshelf" represents something different, but according to the rules of some book towers or Treasure Pavilions, the better things are always placed on the very top level.
So Ling Zhenfei also fixed his gaze on the cave at the very top.
However, although there were quite a few caves actively pulling at Ling Zhenfei, the topmost cave was not among them.
