Xingyun Li

Li Xingyun, with a mysterious background, wandered the martial world at the age of nine. After the battle of Yuzhou City, Li Huan died, and Li Xingyun became a disciple of Yang Shuzi, learning martial arts. Eight years later (the second year of Qianhua, 912), he left the mountain and traveled the martial world with his junior sister, Lu Linxuan. Because he possessed the Longquan Sword and his true identity was exposed, he attracted the pursuit of various forces. Later, he met Ji Ruxue, a maid of the Huanyin Pavilion, and Zhang Zifan, the young master of the Tongwen Hall, and the four became friends, venturing into the martial world together.
