The four brothers of the Qin Family were all thinking that Grandma must have given the seasonings to Zhenzhen.
When Zhenzhen was at home, she had never left their sight. If she had met some otherworldly expert, they would have known about it.
She was not familiar with the Qian Village, and she spent most of her time at her mother's home, so she did not know anyone who would give her the formula.
But why did Grandma want Zhenzhen to make such an oath?
Oh yes, the whole family knew that their grandma had a story.
The old books in Grandma's box were about how to use medicinal herbs and ingredients to cook delicious and therapeutic food.
But grandma had never taught any of them how to cook.
They had also guessed that it was Grandma's secret.
Now that Grandma gave them the recipe for seasonings and asked Zhenzhen to keep it a secret, it was not difficult to understand.
