In Liang Yusheng's "Returning the Sword", Chen Xuanji's true identity contains the following core information, Chen Xuanji is the illegitimate son of Yun Wuyang and Chen Xuemei. Yun Wuyang pushed the pregnant Chen Xuemei into the Yangtze River in the war because he was greedy for life and afraid of death, but Chen Xuemei survived and gave birth to Chen Xuanji. Twenty years later, Chen Xuanji assassinated Yun Wuyang on the order of Zhang Shicheng's old department, but accidentally fell in love with his half-sister Yun Susu, and finally after the truth of his life was revealed, Yun Susu committed suicide by jumping off a cliff, and Chen Xuanji was also disheartened.

He is the source of the "Tianshan School", and he calls himself "Xuanji Yishi", with outstanding martial arts, and is known as "the first swordsman in the world". He has profound martial arts attainments, proficient in stunts such as "Yuan Yuan Xuanji Swordsmanship" and "Finger Snap Magical Power", and has created "Male and Female Double-strand Swords" (Baiyun Sword and Qingying Sword).

In "Pingxia Film" and "Scattered Flower Woman", Chen Xuanji, as Zhang Danfeng's ancestor, did not appear directly, but his martial arts inheritance and sect status are very important to the development of the Tianshan faction. In his later years, he lived in seclusion in Cangshan, accepted five disciples including Dong Yue and Xie Tianhua, and laid the foundation of the Tianshan faction.

Chen Xuanji is not only a tragic figure (with a chaotic life and a broken love) but also the spiritual founder of the Tianshan School, whose identity is intertwined with family grievances, martial arts disputes, and personal fate.
