"Hmm." The Old Master nodded, not denying it.
"There was a white hair among your jet-black locks that was an eyesore, so I plucked it out, but didn't expect it to wake you up."
The Old Master raised the corners of his mouth in a slight smile.
"No problem, I've slept enough. I was thinking of washing my face; keep an eye on the instrument," Xia Yinian said, instructing the Old Master.
However, she actually had white hair. How did she not know?
At only eighteen, how could she have white hair? Could it be that she's really been too tired these days?
"Go ahead, nothing will happen with me here." The Old Master waved his hand.
Xia Yinian nodded and stepped away.
"Understood, I'll be right back."
The room was right next door, and Xia Yinian returned quickly.
Seeing the instrument hadn't finished operating, she looked at the Old Master and lightly pressed her lips together.
"Grandpa, do you have any particularly effective truth serum?"
