Yingqi's tribe, the Huoli tribe, has always used medical skills to save people, but because of the defects of their skills, they were misunderstood by people in the world, and the tribesmen could only live in seclusion in a small village. Yingnan thought that Bai Guyi, the eldest disciple of Cangxu, whom she met on her eighteenth birthday, was the hero in her dream. In order to pursue love, Yingnan wanted to learn martial arts in Cangxu School, but went to Shushan by mistake. After going through twists and turns, it suddenly dawned on him that Yingqi, who had been silently guarding all the way, was not his real brother, and Yingqi was the one who deserved his deep love.

Bai Guyi pretends to be a righteous person and attempts to destroy the Huo Li tribe. After a fierce battle, Ying Qi and Bai Guyi eventually die together.
