A Yuan's ideal in life is to be the most stable salted fish in the palace, the most dangerous place in the world. With her mediocre cooking skills of "making everything delicious, but cooking nothing well", she managed to lie in the corner of the imperial kitchen for three years. Until one day, she was transferred to a mysterious department-"Anheyuan". Good news: There is less work and less people, the monthly income is doubled, and the master is the most favored but sickly sixth prince in the palace. Bad news: The former cook just "slipped" and fell into the water, and her body is still cold. The Sixth Prince looked pale and never left the medicine bowl in his hand. Every dish he ate was carefully prepared by the Taiyuan Hospital and was known as the "Secret Medicinal Diet". But A Yuan took a sip and frowned so hard that he could kill a fly. Is this so-called medicinal diet, the dosage of nightshade and pinellia, a bit too "exquisite"? If you eat it for a long time, even gods will become sick cats! Seeing the Sixth Prince's increasingly weak body and the secretive eyes of the people around him, A Yuan's salty dream was shattered. She discovered that this was not the kitchen, this was clearly a dragon's pond and a tiger's den! In order to save his own life and save the beautiful prince who seemed harmless to humans and animals, A Yuan was forced to pick up the half-baked medical skills inherited from his ancestors. He cooked vegetables during the day and performed autopsies (bushi) at night, looking for clues among the pots and pans. The poisonous-tongued imperial doctor who always comes to eat and drink seems to know something; the taciturn guard who always appears at her critical moment has an identity that is far from simple; and the imperial concubine who brings expensive ingredients with a smile, but she looks like the mastermind behind the scenes... Ayuan: I am really just a cook, fighting for the heir in the palace and so on.
