Please recommend a novel based on the ancient language. The male protagonist is the emperor, and the female protagonist has never been favored to the point of being favored after becoming a concubine.

The women of the female owner's family had entered the palace to serve the emperor for generations. They were all favored, but their lifespan was not long. The reason was that there was a kind of medicinal soup passed down from his ancestors that could nourish private parts, but it was harmful to his health. The female protagonist was also soaked in medicinal soup since she was young. Later, the emperor brought the female protagonist to visit a famous doctor when he was wearing incognito. The famous doctor knew that it was caused by the medicinal soup, but seeing that the male protagonist was a dignitary, he thought that he would not care about the female protagonist's life. Famous doctors advised the male and female protagonists not to have intercourse. Later, when the male protagonist brought the female protagonist to visit a famous doctor, the famous doctor diagnosed that the female protagonist actually survived and actively treated her. He was very touched by the male protagonist's feelings for the female protagonist. When the female protagonist first entered the palace, the male protagonist thought that the female protagonist was very scheming. Including the female protagonist meeting the Emperor in the Imperial Garden (in fact, it was the servant girl who suggested the female protagonist to go there to pick flowers), the female protagonist meeting the Emperor and his officials when it was raining, the Emperor (male protagonist) thought that the female protagonist had planned it and deliberately created the encounter. When the female protagonist was not favored, although she was anxious, she still showed very little, such as cutting window decorations, planting flowers, and so on. In the middle part of the fourth book, the female protagonist (at this time, the female protagonist seemed to be the Empress) was framed and punished in the temple. Then, because the male protagonist went to the temple in the middle of the night, and because the female protagonist stopped him when he kicked the female protagonist's servant, he kicked the female protagonist's heart, causing the female protagonist to vomit blood. After 5, the female lead shaved her hair and returned to her hometown for some reason. After that, the emperor went to the female protagonist's hometown in disguise. When it rained heavily, the male protagonist fell ill. The guards asked the female protagonist (Niangniang) to take care of the emperor and feed the emperor medicine. The emperor thought that he dreamed of the female protagonist again. There was also a paragraph about the emperor bringing the female protagonist to wear plain clothes or go to Jiangnan. The emperor liked women outside the palace, those bold and bright types, but this time it was to make the female protagonist jealous. There was also a segment where the female protagonist accompanied the emperor to deal with the flood. She found that a vortex was about to form on the shore and asked everyone to evacuate. Above. The male protagonist feels a little like the male protagonist of "The Confusion of Mind", and the female protagonist also feels a little like it. In addition, the above six points are the fragments that I vaguely remember. Some of them may not be correct, and may be confused with the Confusion of Mind or the Legend of Zhen Huan. However, the female protagonist has the characteristic of making medicine soup.
