A sudden global outbreak of Satiety Syndrome causes humanity's food consumption to plummet to one-twentieth of its former level. The only person unaffected is Jiang Bei, a food delivery rider. To survive, he enters a competitive eating contest and becomes an overnight sensation, attracting the attention of powerful business tycoons. After discovering that he is the source of the global mutation, Jiang Bei refuses to let corporations monopolize the food supply. Instead, he joins forces with the International Food Safety Organization to develop affordable, nutritious food and fight against relentless suppression. In the end, he makes the formula public, saves the world, and returns to an ordinary life.
