This time, Qiao Nian didn't doubt Doctor Su's words. She believed that his medical skills were definitely solid. Only then could he have become Grandma's attending physician.
However, this time, Grandma's pulse did indicate that she had been poisoned.
This time, she was not entirely confident that she could save Grandma.
But now, if she could find out the cause of Grandma's poisoning, she could save her.
Qiao Nian's heart was beating wildly, but her expression remained calm. Her gaze fell on a table not far away.
There was a blue and white porcelain teacup on the table. Jiang Yue had handed this cup to Matriarch Gu just now, and Matriarch Gu had finished all the tea in it.
A servant handed Matriarch Gu's medical records to Qiao Nian. Qiao Nian took the documents from him and looked up at the butler. "Butler, go and get the dregs of the medicine I've brewed, as well as the dregs of the cold medicine from just now."
