Huo Jinyan was certainly in a bad mood. In order not to bring his emotions into the lesson, he had been holding it in, afraid that he would scare the entire class with a single, inappropriate outburst.

The other day, he had spent a lot of effort in the curriculum room digging out Lu Ning's previous test papers. And he found out that, as that teacher had mentioned, some of Lu Ning's tests were really strange; she could not do the simple questions, yet she could do the difficult ones.
