Yun Zhilan was Sigu Jian's first disciple. He was a martial artist at the grandmaster level and was proficient in Sigu Sword. He was considered one of the four grandmasters. He had displayed outstanding martial arts and intelligence. He was Fan Xian's right-hand man. Yun Zhilan's two disciples were Lin Shu and Lin Yao. Under Yun Zhilan's guidance, they learned a lot of knowledge and skills and became outstanding warriors. Yun Zhilan was the governor of Dongyi in the movie. He had fought with Fan Xian and the others and played an important role in the plot. Yun Zhilan's strength was recognized by everyone, but among the ninth-level aces in the Qing Kingdom, there were at least three people who were stronger than him. Thus, although Yun Zhilan was Sigu Jian's first disciple, he was not the strongest ninth-level ace.
