Chen Langyue had to return to Muyu Academy, but the emperor said that the Beizhou Mission was coming and asked her to stay in the palace, but Chen Langyue said that she would return to the palace when the mission came, and the fortifications of Liao's house were not over yet. Regarding Li Qingfeng, the emperor warned Chen Langyue that he could be a friend, but he could only be a friend. Tomorrow is the Mid-Year Festival. Li Qingfeng suddenly invited Chen Langyue to go home with him to visit his parents. Chen Langyue was a little apprehensive, but after thinking about it, she would explain her identity sooner or later, so she agreed to Li Qingfeng. The next day, Chen Langyue brought gifts to the Li Mansion, but Wang Sheng suddenly told him that the emperor wanted her to return to the palace. Back in the palace, Chen Langyue saw He Zhigu, the thirteen prince who led the Northern Zhou mission, and He Zhigu fell in love with Chen Langyue at first sight. During the dinner, the emperor and He Zhigu seemed to be chatting, but hidden secrets everywhere, the friction between the Great Depression and the Northern Zhou Dynasty had intensified. After that, He Zhigu invited Chen Langyue to visit Zhongyuan Ye at night. Due to the emperor's face, Chen Langyue could only agree. Then she rushed back to Muyuyuan to find Li Qingfeng who was sulking. Li Qingfeng blamed her for not keeping her promise. Chen Langyue dodged because she didn't know how to tell the truth, which made Li Qingfeng even more angry, and Li Qingfeng's anger made Chen Langyue feel wronged, and the two broke up unhappy. After that, the emperor even asked Li Qingfeng to take Li Qingfeng to his villa. He did not reveal his identity, but told Li Qingfeng as the brother of Chen Langyue that Chen Langyue had a marriage contract long ago.
