The next day at noon.
Zhou Ning was playing chess with the old man before lunch when his phone started ringing. He put down the chess piece and stared at the board for quite a while, leaving the old man with a puzzled face.
"Hurry up and answer the phone. What are you looking at the board for?"
Zhou Ning was on guard.
"I have to make sure I remember the positions; otherwise, Grandpa might swap them, and I wouldn't even know how I lost. You've cheated more than once or twice, so I need to be cautious."
The old man was speechless, then picked up a cushion and threw it at Zhou Ning.
"Stop your jabbering and answer the phone, you brat."
Zhou Ning took out his phone, glanced at the name on the screen, and begrudgingly answered the call.
"What's up, Doctor Lu?"
Seeing the old man raise his hand, Zhou Ning instinctively dodged further away, escaping the old man's striking range before he paid close attention to Doctor Lu's voice coming from the receiver.
