"Quiet."
Lu Qingyi slammed the desk seriously, her command was stern.
The authority in her eyes was just like that of senior professors.
Wei Song instantly straightened up like an obedient student.
Classmates: "..."
No way, right?
What's with Wei Song? The posture is just killin'.
Seeing Wei Song's seriousness, other students couldn't help but become serious as well, lest they get scolded by Wei Song later on.
"Any questions?"
Lu Qingyi first glanced at the test paper and then asked the students below.
"Qingyi, I don't quite get question 20."
Li Xianya was the first to raise her hand, saying to Lu Qingyi.
Well, she truly doesn't understand.
"Ok, this question can be done like this..."
Lu Qingyi turned to write something on the blackboard, then began to explain.
"Damn! It's so easy, really?"
"When Lu Qingyi has explained it, I feel like I've understood it all."
"Is this what is meant by 'one point leads through it all'?"
