Lin Shouyi, a traditional chef who strictly upholds culinary ethics, is betrayed by his apprentice Tang Liu, who steals his family's ancestral recipes and brings his restaurant to the brink of bankruptcy. By chance, the stove in his home restaurant becomes connected to the ancient Great Wei Dynasty, allowing him to meet Xiao Yanzhi, a prime minister suffering from chronic loss of appetite, and Ling Yue, an upright general. Using his home-style cooking to cure Xiao Yanzhi's condition and trading modern supplies for rare ingredients and ancient recipes, Lin brings his restaurant back to life. When devastating floods strike Great Wei, Lin travels through time to provide disaster relief, bringing food supplies and water-purification equipment, setting up porridge stations to help the people, and discovering the complete version of his family's ancestral recipes. When corrupt officials stir up trouble at court, Xiao Yanzhi and Ling Yue put aside their political differences and join forces to restore order. At the God of Cooking competition, Lin defeats Tang Liu, who relies on piling up expensive ingredients, with heartfelt home-style dishes.
