Modern kitchen worker A Man unexpectedly transmigrated, becoming Shen Yan, the young master of the failing Zuixianlou in Jiangnan during the Northern Song Dynasty. Facing the restaurant's debts and lack of ingredients and seasonings, he relied on modern knowledge to improve and refine fine salt, and develop soy sauce, vinegar, and composite spices. Successively resolving crises such as grain merchants' obstruction and malicious peer competition, he step-by-step expanded the dilapidated Zuixianlou, opened chain branches, built greenhouses and ice-making courtyards, and with his craftsmanship turned the bankrupt restaurant into a well-known Jiangnan culinary commercial firm, living a stable and cozy life.
