During the day, Chen Mo was a delivery boy riding an electric donkey, struggling to make ends meet. Late at night, he is the most popular stall owner on the banks of Wangchuan River. With a bowl of steaming Yangchun noodles, he can end his obsession with death. It wasn't until Po Meng came to his door and the "seasoning theft case" in the underworld came to light that he was shocked to realize that his grandfather's disappearance was actually related to the Chen family recipe book that was said to be able to "reconcile yin and yang". From then on, he delivers yin and yang with one takeaway and cooks heaven and earth with an iron pot. Amidst the fireworks of the world and the cold wind of the underworld, he pursues the truth and protects the last warmth of the two worlds.
