In the Fairy Slaying novel, the Valley Master of the Valley of Incense, Yun Yilan, had the ambition to become an outstanding figure in the martial arts world and control the entire martial arts world. He had powerful martial arts and intelligence, and he had been planning how to achieve this goal. His plan included recruiting more martial arts masters into the Valley of Incense to become the top figures in the martial arts world through training and sparring; using the resources and strength of the Valley of Incense to create powerful weapons and equipment to strengthen himself; spreading slang and rumors in the martial arts world to create chaos and threats to weaken the strength of other martial arts sects; and using his wisdom and connections to plot all kinds of complicated conspiracies and open schemes to achieve his goals. Yun Yilan had great ambitions, but he knew that his strength and resources were limited, so he had been acting cautiously and constantly seeking resources and support to realize his plan.
