Qin Yao looked up, displeased, and said seriously:
"Put away your thoughts. The raw material is pig fat. We can't do this business, and I have other uses for this recipe. Save your effort; it can't make our family rich."
Hearing that the raw material was pig fat, Liu Ji exclaimed silently, "My goodness."
No wonder it's so effective, turns out it's made with pig fat.
But…
"Wife, what do you want to keep this recipe for?" Liu Ji asked curiously.
Qin Yao gave him a sidelong glance, "Don't pry into the old lady's business!"
Liu Ji smiled, "Alright, I'll take my leave now. Wife, rest early, don't read the account book too much at night, you'll strain your eyes."
He retreated with a strong will to survive.
Before leaving, he went to the kitchen to find an old clay bowl, added a layer of ash inside, and put a few pieces of charcoal to avoid freezing to death at night.
Actually, Qin Yao never skimped on bedding; there were thick quilts in the room.
