Yun Zhan, the young lord of the city, and his fiancée were separated during the war. In order to protect his family and country, Yun Zhan served in the army and gradually rose to the position of general. During the war, Yun Zhan's fiancée Mo Youer came to find her after hearing false news. The two promised to grow old together in the southwest Luo City after the war, but they did not want to be separated during the war. Mo Youer lost her way in the wilderness and was kidnapped by the enemy. During interrogation, she met Mo Zimo, the third prince of the Northern Territory. Suffering so much, he was reduced to human form. Jin Huan, who happened to be found, rescued him and escaped from Nanqi. Jinhuan died unexpectedly while protecting Mo Youer on the road. After Mo Youer left, Mo Zimo realized that he fell in love with Mo Youer, so he summoned all his men to secretly search for Mo Youer's whereabouts. In the final battle, Xuan Yue defeated Beiyu, and both countries suffered numerous casualties. Yun Zhan planned to fake his death and leave Luo City. Let his subordinates look for Mo Youer everywhere.
