In the end, Yun Xi thought of a particularly clever method. She grounded these expensive Chinese herbs into powder, then added milk powder and some icing sugar into the powder to make it look like a tonic for the old man to take.
In this era, although milk powder was not cheap, it was still much cheaper than Chinese herbs like ginseng and lingzhi. This made the Old Master feel less burdened.
"Grandpa, drink it."
Yun Qiao put the cup on the head of the old man's bed and handed it to him.
"What kind of tonic is in this cup?" The Old Madam asked curiously.
"This is milk, which can supplement nutrients," Yun Qiao answered with a smile. He did not plan to tell the Old Master and the Old Madam the truth about this milk powder.
The Old Madam was a little surprised to hear Yun Qiao's answer.
