"Why do you think they can't learn the celestial abilities within the White Cloud Cave?"
"Because the heavens do not permit!" Master Yuan's eyes sparkled like lightning as he looked at Xu Qing.
"Your monk senior brother did indeed copy all the celestial scriptures from the two stone walls in White Cloud Cave, but only the twenty-four pages of Earthly Fiend Celestial Scripture on the right wall held text, while the thirteen pages of Heavenly Gang Transformation on the left did not contain a single character."
Master Yuan laughed and said, "This is the void of heaven, the reality of earth. Even though the Earthly Fiend techniques can manipulate all sentient and tangible things, they are limited to worldly transformations and ultimately confined by the numbers of heaven."
