Li Qiao's heart understood as she picked up the prescription from the pharmacy, "Then these?"
Shang Lu wiped his hands with a tissue, "The generic version, common formulas from Shang Family Traditional Chinese Medicine Hall. I specifically asked for these for you."
Li Qiao's gaze swept across the table, "So, there's only one copy of the old mansion's contraceptive secret recipe, but there are twelve copies from the pharmacy."
"Yes," Shang Lu said, pushing the prescription he had just written to the other side of the coffee table, "I haven't researched how many contraceptive recipes the old mansion has, but last night I went through all the medical books related to women and only found this one. The recipe left in the medicine residue is written here; it's the old mansion's secret recipe, identical. My brother must have prepared it for you."
