Zhou Danni's house.
The bun business has been poor these days. Old Zhao didn't return until after 7 o'clock in the evening, and only 20 buns were sold out of a hundred!
There were 80 left!
They had so many leftover buns from the past few days that the family couldn't finish them even after days.
Looking at the buns, old Zhao grew worried. He searched his pockets for a cigarette but instead found a slip of paper.
This slip of paper was from Ni Yan's previous visit.
It was the recipe for making ketchup.
Ni Yan had written it out very clearly in great detail. It was easy to understand.
Old Zhao looked at the piece of paper and said to Zhou Danni, "How about we try what Yangyang suggested? We could sell the grilled bun pieces by the school gate."
Zhou Danni frowned, "That uses a lot of oil, and we don't have a lot of sesame oil left at home."
