In modern cities, there is a hidden world of monsters, parallel to human society. The monsters incarnate into various forms, the most special of which is the "food spirit" that is cultivated from the recipes. These food spirits must be attached to human chefs and maintain their spiritual power through cooking. The protagonist, Chef Ye, accidentally acquires an ancient cookbook, "The Food Book of Mountains and Seas", which contains hundreds of food spirits sealed in it, and thus begins a ridiculous gourmet adventure.
