Bab 436: Chapter 269: The Expert Left, How to Teach Now?_3

Zhao Yi pursed his lips and only after a moment of thinking did he respond, "Oh, I was pondering over another problem, sorry, I understand it all, thank you, Teacher Hu, this is a big help."

Hu Zhibin forced a smile across his face.

If he was dealing with an ordinary student, he would have picked up a book and whacked him straight across the mouth.

Hadn't he just spent half an hour painstakingly explaining the topic?

And what was the outcome?

Not only had he not been paying full attention, but he also blatantly admitted that he was pondering over another problem entirely.

Luckily, the last sentence was comforting, "A help? If it helps, then that's good."

Hu Zhibin knew it was polite talk. How could what he taught be linked to the Goldbach Conjecture?

What a laugh!

Not at all possible!

Even though it was merely casual talk, it still sounded comforting.
