Looking for a romance novel

It was about three years ago. At that time, it was still in a serial. The name had four words, and there seemed to be the word "Tian" or "Jiao". He didn't remember the details.
The general content was that the female protagonist's brother was a very smart and talented person, but he died young. The female protagonist pretended to be his brother and took on a position similar to that of the prime minister. In order to go to war, she revealed her identity to the emperor. Soon after, he fell off the cliff with the enemy commander. After losing his memory, he fell in love with the enemy commander. (It should be mentioned here that the female protagonist has the destiny to break the heavens. A mysterious handsome man proposed to her before the female protagonist went out to fight. He also gave her a piece of red jade as a token of love. Although the female protagonist's brother died, his soul did not leave. With the power of this red jade, he could share a body with the female protagonist.) After they got the magical lotus seed at the foot of the mountain and walked out of the cliff, the female protagonist's brother possessed the other party's commander and gave him a knife. He also let the female protagonist recover her memory and forget what happened at the bottom of the cliff. Then, he found out that the Emperor loved the Female Lead's brother. The State Preceptor, who was the master of the two siblings, wanted the Female Lead's brother to take over the Female Lead's body and marry the Emperor as the Empress.
I remembered that I had already finished the series here. It was amazing why I didn't continue reading it. Yesterday, I suddenly remembered that I had read this article. I was a little concerned about the ending. I wanted to see if anyone had read it before and still remembered it.
PS: It seems that there is someone called Yiyi inside.
[PS: After the female protagonist took over her brother, her family adopted a daughter. It seems that she had transmigrated. In the end, she still had some entanglement with Tanhua.]
PS: The emotional entanglement between the female brother and the emperor originated from a bath by the river when she was young.

As someone who loves reading novels, I don't have the ability to search for novels. However, I can recommend you some classic romance novels such as " Silent Sheng Xiao "," A slight smile is very beautiful "," The concubine's daughter is poisonous "," Hua Qian Gu " and so on. These novels are all very popular. The writing style is beautiful, and the plot twists can bring you a pleasant reading experience.
