Lin Zhou accidentally broke into a parallel world, and with only a few change in his pocket, he decided to set up a stall and sell snacks relying on ancestral craftsmanship. He does not have a fixed stall and sets out stalls randomly, but with his unique authentic flavor, he quickly captured a large number of diners. As soon as a stall is set up at the entrance of an alley, the scent can attract people from half the street; sometimes when the stall is closed and moved to another location, regular customers can chase the scent for 10 streets just to buy a hot snack. From being ignored by diners to being chased by diners, Lin Zhou's random food stall has become a "mobile treasure" in the city, allowing him to gain a foothold in a strange world with the help of fireworks.
