Xu Yunqing was called a bastard from childhood and despised by the rest of his clan.
After his family was murdered and he lost them, Xu Yunqing was driven out by his clan and spent three years on the streets. A Taoist priest rescued him and took him to Mount Wudang, where he became a disciple of Master Baimei and trained in peerless martial arts! After coming down from the mountain, he vowed to avenge his parents. This set Yunqing on his path through the martial world, where the thirteen sects held a tournament. Heroes from all over gathered, and Yunqing emerged as champion, earning the title Yunqing the Great Swordsman and the sobriquet Azure Dragon Sword Immortal. He then made three trips to the Hengshan Sword Sect. On his final visit, the sect faced a crisis, and he was rescued by Situ Xin, the boy he had known long ago. The two became sworn brothers! They later encountered an old scavenger, an unparalleled master who passed his skills on to them. When they returned to the Hengshan Sword Sect, the two swept through the entire sect!
It was all because Situ Xin had a younger sister who had been sent to Mount Longhu years ago!
The two hurried to Mount Longhu. When they arrived, they learned that his younger sister had been bullied there. So the two raised hell at Mount Longhu and turned the place upside down.
