Ms.Zheng gave the leftover medicine to Ms.Fang, but thinking it wasn't enough, she sent someone to buy more from Jishi Hall.
Shopkeeper Zheng had no idea what Watermelon Frost was. Even though his brother was an imperial doctor, Imperial Doctor Zheng couldn't possibly tell him everything going on in the Imperial Hospital.
Some medicines, if not properly prepared, couldn't be discussed outside, not even with family.
Like Zhou Man, who used it directly... well, she was the patent holder, she had that right.
But Shopkeeper Zheng was clueless, though he quickly realized that this was the medicine his brother had vaguely mentioned Zhou Man used to negotiate a spot with the Imperial Hospital.
He suppressed his curiosity and told the Bai Family's servant that such a thing wasn't available outside yet, and it was best to ask Doctor Zhou Junior directly.
Doctor Zhou Junior was having a delightful time in the suburbs until just before dusk when she returned home with Bai Shan and others.
