Lu Yun was just about to say, "Even if you're unwilling to leave, cooperation is still possible, or you could sell the recipe."
Although the Mi Family's recipe was no secret to her anymore, she didn't want to use it directly.
If everyone could cooperate, then cooperate; it would also be an opportunity for the Mi Family, and what she valued more was indeed the Mi Family themselves. If cooperation wasn't possible, she would buy the recipe if it was for sale.
But if the Mi Family was not willing to sell the recipe, that was okay too; truth be told, she didn't absolutely need that recipe. Everything in the world was interconnected, and if feeding ducks herbal medicine from a young age could improve their nutritional value and taste, the same could be done with other livestock.
With her current understanding of the properties of herbs, wouldn't it be easy to come up with herbal rabbits, herbal chickens, and so on?
