Xia Li, the Minister of the Ministry of rites, was declared into the palace by an imperial edict and became Li Zhaoyi. From then on, he entered the palace as deep as the sea and became a canary in a cage. Once upon a time, she met Wei Wushang, the leader of Yulin juntong, the red man beside the emperor. Wei Wushang was surprised to find that Xia Li had eight points in common with his dead sister, the most beloved concubine of the emperor, LAN Guifei and Wei Xinlan. At the same time, empress mu Yinqiu learned the news and tried everything to prevent the emperor from seeing Xia Li. With the help of Duanfei, the head of Yaohua palace, Xia Li met the emperor and learned a secret from Wei Wushang and his father. It turns out that the former concubine Lan was the sister of her compatriots. Three years ago, Wei Xinlan accidentally drowned when she was in Liujia's arms. Meifei almost lost her life just for her. However, after repeated thorough investigation, the emperor still failed to find out the real murderer. After Xia Li knew it, she was determined to join hands with Wei Wushang to avenge her elder sister, and she began to become more indifferent and win the saint's favor with all her heart. Later, the murderer was caught. It was Wei Xinlan who drowned and saved her Meifei in spite of her life!

When Mei Fei is arrested, Xia Li doesn't take a breath of relief as he thinks. Instead, he thinks things are more strange. At this time, she has been deeply involved in the imperial power and cannot extricate herself. Wei wushangben's heart is Wei Xinlan's, so after her death, she insisted on going to the palace to find out the real murderer for her. However, gradually, he found that he fell in love with Xia Li. Looking at the once simple and lovely girl becoming more and more mature and charming, Wei Wushang begins to regret that Xia Li was involved. But nothing can change. Xia Li is totally fascinated by the emperor. After her efforts, she finally knows that the black hand behind the scenes is the seemingly harmless Duanfei Niang! She, Mei Fei and even the empress are played by Duanfei.

Finally, she and the empress Qiangqiang, who has been beaten to the cold palace, finally revealed the true face of Duanfei, and Xia Li was also named Queen. A hundred years later, the throne was passed to Xia Li's son, while Xia Li gave the Queen's position to Mu Yinqiu, the empress. He lived a carefree life in the mountain forest with Wei Wushang, who had been guarding her.
