This scene was an eye-opener for Chu Yunfan!
What kind of powerful spiritual power was this to be able to make a book project an image of a martial arts expert?
These images were practicing martial arts day and night. The person who imprinted these martial arts techniques must be a powerful martial arts expert.
These martial arts secret manuals were not cultivated like ordinary martial arts secret manuals. Instead, one could sink one's divine will into them and comprehend them directly. This way, the comprehension speed was ten times or even dozens of times faster than ordinary martial arts secret manuals.
