Liu Yaya, a peasant cook, was selected into the general's mansion because of her outstanding cooking skills, and became the lowest maid in the kitchen. Faced with the bullying of other servants and the difficulties of Mrs. Side, she won the favor of the general with her good cooking skills. She was also bound to the "food buff system" and the dishes she cooked could boost energy and relieve pain. When the general went on an expedition, she appeased the soldiers with delicious food, and also used system prompts to see through the enemy's poisoning plot. She worked her way from a kitchen maid to become the general's right-hand assistant, and finally married the general, witnessing him to bring peace to the world with her delicious food and wisdom.
