It is rumored that Sihai Pavilion at Luopan Mountain teaches disciples according to their talents. Whenever a disciple descends the mountain, they either become a renowned swordsman like Gu Yijian, or a famous water conservancy expert like the former Yan Kingdom's Sima Sheng, or a powerful Prime Minister like Wei Kingdom's Gongsun Chancellor.
When Bai Qingyun decided to go to Sihai Pavilion, he held onto a sliver of hope... hoping that Sihai Pavilion, reputed for its mastery in Qimen Dunjia, could heal his legs.
But after arriving at Sihai Pavilion, Gu Yijian told Bai Qingyun that Qimen Dunjia was not as miraculous as rumored outside; it couldn't bring flesh back to bones or regenerate limbs. He asked Bai Qingyun to make a choice: spend over a decade just to barely stand with his legs, thus ceasing to be a martial artist, or... give up his legs to learn things that Bai Qingyun couldn't learn elsewhere.
