Crossing over to become a broke noodle shop cook that no one wanted, Su Wan starts off with a broken engagement, debts, and a stolen shop. But who would have thought that a modern five-star hotel chef, upon reaching ancient times, would become the greatest "food assassin"! She improves recipes, runs restaurants, builds a signature brand, and step by step turns the little broken shop into a city-renowned culinary kingdom. Only when she stands at the peak does a photograph from modern times appear: "Number Seven, survival confirmed." Then she realizes that an even greater secret lies behind her crossing over.
