章 217: Playing Around

After two consecutive days of exams, the weekend finally arrived.

Early on Saturday morning, Nan Yan received a call from the headmaster asking her to come to the laboratory.

Old Master An had just finished his morning routine and was about to have breakfast.

Seeing her about to leave, he couldn't help but ask, "Yanyan, isn't today the weekend? Why are you up so early?"

"I have something to take care of."

Nan Yan picked up a piece of bread from the dining table, looked at Old Master An's noticeably improved complexion, and casually asked, "Grandfather, how have you been feeling lately?"

Old Master An chuckled, "Not bad at all. Yanyan's medicine is quite effective. I must say, I feel much better than before."

Nan Yan was confident in her medical skills and nodded, "Then keep taking it, and remember, maintaining a good mood is also important."

"Yes, yes, I know!" Old Master An replied.
