"Who brewed this medicine?" Qiao Nian turned to look at the butler and asked sternly, "Why did you add so much safflower?"
The butler glanced at Qiao Nian and frowned slightly. He said, "I weighed the ingredients for the medicine myself, and brewed it myself too. I followed Doctor Su's prescription exactly."
Qiao Nian's expression grew darker and darker. She frowned slightly. She trusted the butler. He would never do anything to harm her grandmother.
Qiao Nian looked up at Gu Zhou and said, "Someone wanted to harm Grandma by swapping the medicinal ingredients in the medicine cabinet!"
The butler did not know much about medicine. All he knew was to select the medicinal herbs according to the labels on each compartment of the medicine cabinet.
Gu Zhou turned to look at the butler and said coldly, "Lock the medicinal room. Investigate who's been in there lately."
