After being unemployed for three months, Lin Kong has earned only 20 yuan from three days of street vending and can barely afford his rent. At his lowest point, he gets bound to the Ultimate Ingredients System. Risking most of his savings, he cooks a batch of five-spice peanuts, only to see customers who initially complained about the price come rushing back to buy them! But the system changes its merchandise every day. Just as the peanuts become a huge hit, they run out. Then his grilled meat becomes so irresistible that customers line up for ages, while snow-patterned lamb selling for 500 yuan per jin becomes the object of fierce competition, with customers scrambling to buy it all. With a different menu every day and a business that keeps growing, can this secondhand food cart become the starting point of Lin Kong's comeback?
