In casting, CCTV will be different from the bold use of newcomers in the Tang Dynasty. The first hero in the play, Pawnshop Boy, will be played by a new generation of mainland actors who have appeared in Chivalrous Man and The Journey to the West, while his "Tell the Judge, Miss Tangmen in Central Sichuan" will be played by a young actor Miao He, and Zhang, who plays the opposite role in Chivalrous Man, will play the personal maid this time. Yaqi fatimai, a famous young Hui actress in China, will play two roles in the play-the Uighur princess Solanum nigrum and her body double Qingying. It is worth mentioning that she once played Arjun and Tamia Liu and Hu Jun of Qiao Feng in Zhang Jizhong's Jin Yong blockbuster Dragon. This time, she will play the opposite lovers again, playing Zi Xuan and Paris respectively. As for Zi Xuan's third lover, Xu Changqing, who was expelled from Shushan School, is tentatively played by Wang Yanan, a young actor who once starred in Flying Dance with Korean actress Kim Hee Seon. In addition, Jin Ming, the actor of "Small International Nuclear Accident Scale", Liu Dekai, a veteran movie star in Taiwan Province, and Zhang Guoli and Deng Jie, famous mainland couples, will all make guest appearances.
In terms of plot, the film will make great changes to the original work, except for the tentative title of the film-Legend of the Sword and the Chivalrous Man. The fate of Zi Xuan Nuwa is basically unchanged, and it is no longer a fantasy story in the original work, but a more humanized story, such as changing the female ghost nightingale in the original work into a Uighur princess who fled to the Central Plains due to a palace coup, and adding a corner of "Qingying" for scenic reasons. Finally, in order to protect Solanum nigrum, Jingtian was used to fulfill it. He died, knowing that he was Solanum nigrum's twin sister and the daughter of the Uighur king who left the people before he died. The emphasis on architectural scenes is aggravated, and the imitation of the "dragon" model makes it run through the whole drama with the three main lines of Jing Tian and Changqing. In this film, Paris will appear as a lonely chivalrous man with aloof temperament and superb martial arts. Just because of coincidence, it became a close friend and "prospective master" of Jing Tian, fell in love with Zi Xuan, a virgin of Nuwa, and finally gave up its martial arts completely to save Zi Xuan.
