Can you recommend a novel with the male protagonist being the emperor and the female protagonist being the daughter of an aristocratic family? Was the world of this book a three-pronged confrontation?

Find an ancient novel where the male protagonist is the emperor and the female protagonist is the daughter of an aristocratic family. It was a three-pronged world. There was a plot where the male protagonist was infected with an infectious disease. The female protagonist took good care of him. In the end, the female protagonist begged the Bodhisattva to shorten her lifespan and let the male protagonist get better. In the end, the male protagonist really got better, but the female protagonist was seriously ill. Of course, the female protagonist did not die. The ending of the female protagonist was to save the people of the city and use herself as bait to lure the enemy into the sea of fire.
There, the female lead didn't enter the palace because she was a daughter of an aristocratic family. It was already too late when the emperor found out that the Empress Dowager had conferred the title.
The female lead entered the palace as a noble consort. She had been weak since she was young and had adopted the fourth brother before she had children. Fourth Brother and Fifth Brother were twins. Fourth Brother had heart disease since he was young. The female protagonist had been taking good care of him. Later, the female protagonist gave birth to an elder brother, but the female protagonist did not see him grow up.
The male lead was very sad after the female lead died
The female lead's ashes were not found, which meant that some gold jewelry was found on the female lead's body after she died to replace it
This is a book I read before. I don't remember the plot clearly. I beg for the title and want to review it again.

Answer 1

I recommend "Phoenix Weeps Dew". It's an ancient romance novel about a fight in the palace. It mainly tells the story of the female protagonist transmigrating to the Tang Dynasty and fighting Wu Zetian with her wits. The male lead was a great scholar with a noble status, and the female lead was a girl from a cold aristocratic family. In the story, there were two male leads and two female leads. They fought for power in the palace, but there was also a little pure love. It seems to meet your requirements ~ I hope you like this fairy's recommendation. Muah ~
