Chen Xu was originally busy in the kitchen when he heard what Yanqing said; he suddenly realized.
He had felt something was off about the round-faced man from the beginning. The first time he came to eat noodles, his demeanor wasn't like an ordinary customer's—it turned out he was a competitor; no wonder.
In fact, when people talk about century-old soup, it doesn't mean a pot of soup has actually been stewing for a hundred years. Water and fresh ingredients are added daily.
Every so often, the pot needs to be changed, and the residue at the bottom is discarded. Then, a new batch of ingredients is put in to simmer, and the crux is to add some of the old soup into it. That way, the new batch retains the flavor of the old soup.
It's said that, in old times, when apprentices at similar noodle shops finished their training, they could take a pot of this old soup with them. When they opened their own shops, it became their foundation.
