A modern herbalist disguises herself as an abandoned daughter of a general, and is forced to marry a sick and frail prince. She stabilized the prince's life with a bowl of chicken soup. From then on, she used medicinal food as a blade to fight against unscrupulous slaves, detect poisons, break into the palace, and counterattacked from a concubine who could be bullied by everyone to the most beloved concubine in the capital. The prince originally married her to survive, but he didn't know that he was already addicted.
