The Magic-arts fighting is an important content in Buddhist Scripture. It includes the struggles for powers between Sakyamuni and the Prince of the Devils Boxun, between different religion sects, and between Buddha's. The structure of the struggles is adopted by Chinese classical novels with its content changed into fighting in the Confucianism, the Buddhism and the Taoism.

The first reason of the change is that three religions mix together in Song, Yuan, Ming, Qing Dynasties. The second is that writers accept the feeling standard.
