Can you recommend a fictional dynasty romance novel where the female protagonist looks exactly like her concubine's sister?

The female protagonist and her younger sister looked exactly the same. Although they had the same father but different mothers, the female protagonist's mother was a princess. Moreover, her mother did not like the female protagonist's concubine's younger sister, but the female protagonist especially doted on her younger sister. The female protagonist and her younger sister both liked a prince, and the prince liked her younger sister.(Actually, it was the elder sister. Because the girl she saw when she was young was the elder sister. When the prince saw the younger sister and asked if it was that little girl, the younger sister said it was, so the prince mistook it for the younger sister.) Later, the mother of the female protagonist asked the female protagonist to marry the prince. Although the female protagonist liked the prince, she knew that the younger sister also liked the prince and the prince also liked the younger sister, so she did not agree. However, the mother of the female protagonist was too strong, so she married the prince for the sake of her younger sister. The female protagonist's mother would also send her sister to the palace. After the sister knew about it, she hated her sister very much, so she designed a group of beggars to insult her sister. Because they looked the same, the sister was insulted. The sister told the prince that her sister had framed her. The prince was very angry that he decided to take revenge on her sister. On the day of the wedding, the prince changed his sister to the sister and married her into the palace. In the sedan chair, the female protagonist was not only insulted by the prince, but also poisoned and sent to the palace. At that time, the royal families of other countries came to the country of the female protagonist to discuss state affairs, so the emperor gave the female protagonist to the royal families of various countries to enjoy. In the end, it was discovered that she was not a virgin. The emperor was furious. Later, the female protagonist was locked in the water prison. The king went to see the female protagonist and ridiculed her and told her that everything was his plan. The female protagonist was very sad and angry. She wanted revenge. The water prison collapsed because of the female protagonist's resentment. All the prisoners were smashed to death. The corpses were thrown into the mass grave. The female protagonist climbed out from the layers of corpses. At this time, the female protagonist had been disfigured and covered in bruises. Later on, the female protagonist met a divine doctor and her revenge was about to begin. I didn't read the rest. I don't remember the title. Who knows the title? Please reply. Thank you very much.
