Modern genius chef Dou Dou time-travels to ancient times, binding the nationwide gourmet food clearance system. Relying on modern snacks like potato noodles, barbecue, and spicy hot pot, she struggles to survive, clearing levels and counterattacking all the way. But witnessing the moment when poor grandparents are warmed by food, Dou Dou suddenly comes to her senses, shatters the system with her own hands, and breaks free from the shackles of the mission. Bringing her younger sister Dou Ya'er, she drives a four-wheeled food cart and wholeheartedly sets up a stall. From then on, every episode features a signature dish, and the food evokes the diners' exclusive illusions. Dou Dou no longer chases rewards and fame, healing the dejected with the taste of fireworks and redeeming weary souls with food, writing her own story of worldly fireworks in the market streets.
