"Is it that you don't have time to write it, or..." Li Guangyi paused for a moment and said, "or you don't know either?"
Tan Mo raised his eyebrows. "What you said is very interesting. If I don't know, then where did the answers come from? Are you saying I found the answers by flipping through the information or searching on the internet?
"I have planned to explain during the class," Tan Mo said indifferently. "It's time for class. Go back and sit down first. Once the bell rings, I'll tell you why."
Li Guangyi lifted his eyelids slightly and observed Tan Mo's expression as if he wanted to see a guilty expression on her face.
