Qi Yue smiled faintly.
"Mother doesn't know. All medical prescriptions follow the principle of the monarch, minister, assistant, and messenger for compatibility, and this medicinal wine recipe originates from the same source. If there are others knowledgeable in medicine, they could ponder a little and match the rest of the prescriptions one by one. Since that is the case, it's better for me to just give them away."
Upon hearing this, Granny Zhang suddenly realized, but quickly showed a regretful expression.
"Had I known this before, selling for one million silver coins was too cheap."
"Hahaha..." Qi Yue laughed heartily, "Mother, don't worry, I have plenty of good stuff here—it's just that people in this world might not have enough silver!"
"Yes, Young Miss."
Seeing Granny Zhang was so astute in making money, Qi Yue intended to let her utilize her skills more, and so she asked, "Granny Zhang, where else can we make a good profit around here?"
