Is the movie based on the book?
The movie only borrowed some ideas and a few character names from the "Magic Warriors of Mount Shu" series of books by Huanzhulouzhu (Huan-Zhu-Lou-Zhu). The story is entirely new.
For example, in the movie:
Ting Yin is the main good guy;
Abbot Hsiao Yu is another good guy;
Li I Chi has the double magic swords;
In the books:
Deng Yin is a bad guy who became the Blood Demon;
Abbot Hsiao Yu is another bad guy;
Li Ying Chiong has the purple sword only (and is the principle character);
The Countess, Heaven's Blade, and the three young characters do not exist
