This is why Wuxia (just sword and flying martial arts) is a better genre if you dream to have a movie adaption.
The cost for Xianxia/Xuanhuan special effect is hard to recover. Imagine if the Heavenly Thundering Dragon appeared in this chapter and next chaper the While Illusion Tiger. And next chapter another Black Earthen Turtle appeared. If would be worst, if we add a billion elves and dwarves, or some exotic species found in those two genre. At best those two genre would be for animation or manga perhaps game. :(
It was a bad result for xianxia and xuanhuan writer. I have some interest to check the movie before, but I doubt it would get an international release.
Sometimes a short movie wouldn't enough to show the character deep and wold building found in the novel.
