Ordinary youth Lin Xuan accidentally binds with a system, gaining rich rewards simply by completing street-vending tasks across various locations. Starting by selling roasted chicken wings at the entrance of a proctology hospital, he moves around blind-date corners, stadiums, and livehouses, and even travels far overseas to Colmar to unlock all kinds of specialty foods. Lin Xuan refuses to open a shop or take capital investment, preferring the casual freedom of street vending, and is assisted by the intelligent robot Buritz. Along the way, he meets many lively and interesting diners, experiencing numerous hilarious and absurd amusing events. A group of veteran diners forms the 'Boss Lin Arrest Group' to track his whereabouts everywhere. Afterwards, Lin Xuan begins a nationwide tour of vending, walking through city after city to warm ordinary people from all walks of life with delicious food.
