In the original novel, he and Qiu have emotional lines, but they love each other and kill each other, but in the adapted plot, their emotional lines have completely changed, becoming Qi Yan and Cheng Ruoyu. His background in this play is a double-faced son of heaven. He has been caught between Scylla and Charybdis since he ascended the throne. On the surface, he has always been a vassal of Nuo Nuo, but behind his back, he has always been scheming.
Ji Yan's attention has been focused on the cause of the emperor. He has always wanted to clean up the traitors and villains in the imperial court, so his setting is more emotional, and his personal design is to continue the late Tang emperor Li Yan. He always wanted to revive the Tang Dynasty, but the traitor tied him behind his back, but he had a strong imperial ambition, so he always endured humiliation, so the adaptation of this role continued the ambition of the young emperor to a certain extent, but the appearance of the heroine became successful.
There is also the prototype of Ji Yan, that is, Tang Wuzong Liyan. He got love, but the ending was tragic. He ascended the throne when he was young, but was forced to become a vassal by a traitor. He had no choice but to do something that hurt the loyal minister, so he was gloomy in the early stage. Later, he met the female host and had a good impression on him because of her kindness, but it did not change the ending of his early death.
