Please recommend a novel describing the Liao King and Khitan!

The content of the novel is like this. My memory is a little chaotic. I hope everyone can understand. You must tell me the answer!
The female protagonist was the daughter of a general in the Central Plains (I think she was a general, but I remember that this general later rebelled and became the emperor, so this woman was the princess). The male protagonist was the king of the Liao Kingdom, probably called Ye Lui or something.
I can clearly remember that the plot was like this.
1. At the beginning of the story, it was written that the female protagonist's mother had just given birth to her, and then a fortune-teller told her the woman's fate.
2. When the female protagonist was 56 years old, the male protagonist, as the second prince of the Liao Kingdom, came to the female protagonist's house to visit the female protagonist's father. At that time, the female protagonist was peeking from the tree outside the living room. As a result, she accidentally fell from the tree and fell into the male protagonist's arms. This was their first meeting. Then, the female protagonist was punished by her father to stand in the backyard. At that time, there seemed to be a little boy accompanying her. He was the second male lead.
3. At first, the female protagonist's father was a loyal minister and a good general. Later, he gradually became greedy. After the rebellion, he could only be a puppet emperor under the protection of the male protagonist. Later, he really wanted his daughter to poison the male protagonist. The female protagonist put the poison in the medicine she wanted to drink and let the male protagonist taste it first. The male protagonist knew that the medicine was poisonous and wanted to drink it. The female protagonist still couldn't bear to kill him, so she knocked the spoon away. In the end, the man gave up conquering the Central Plains and lived a civilian life with the female protagonist. 10 points ~~~

The book "The Legend of the Western Liao" was about the Liao Dynasty established by the Khitans in the 12th century. The Nuzhen clan rose in the northeast, and the Wanyan Aguda family established the Great Jin Kingdom. Yelu Dashi, a descendant of the Khitan royal family, accidentally got to know Li Tiansheng, a Han teenager who had come to the Liao Kingdom to steal the ancestral military book. Emperor Yelu Yanxi was defeated and fled to Jiashan. Yelu Dashi supported Yelu Chun as the emperor in Nanjing…Yelu Dashi was captured by the Jin Kingdom. He met Li Tiansheng again in the Jin Kingdom camp and suspected that Li Tiansheng was a spy, but Li Tiansheng tried to rescue him. When Wanyan Aguda died of illness, Yelu Dashi fled to Jiashan and met with Yelu Yanxi, the Liao Emperor. He failed to convince the emperor and resolutely took 200 relatives to the north desert…After the Jin Kingdom destroyed the Liao Dynasty, they quickly launched a war to destroy the Song Dynasty. Li Tiansheng went to the Song Country to form an alliance and handed the military book to Zong Ze. After returning to the north of the desert, Ye Lui Dashi's Eastern Expedition failed. Due to the circumstances, the Khitans embarked on the journey of moving westward…I hope you like this fairy's recommendation. Muah ~😗
