Youyou was on the phone, telling herself that she really wasn't asking for help.
If Shen Lingfeng could do it, she would continue to work on it herself. If Shen Lingfeng couldn't, then she would feel free to just skip that problem.
The "beep beep" sound lasted for quite a while before the call was answered.
The voice on the other end sounded doubtful.
"Shen Lingfeng, it's Youyou!" Youyou spoke quite straightforwardly, "Take a look at today's math homework, page 48, that problem. Can you solve it? ... Ah, you actually can... I don't believe it... So, how did you think about it? ... Is it like this?... Oh, so that's how you do it..."
As she spoke, Youyou held the phone in one hand and started calculating on the paper with the other.
When she hung up the phone, she realized that without even thinking about it, she had asked Shen Lingfeng about a problem!
