QUICKENING OF HIS HEARTBEAT

"VERY good, student Luo," praised Wu Hai after checking the answer written by Luo Yan on the board and confirming that it was correct.  He must say that he was truly impressed by this kid.  After a week of observing him, Wu Hai could confidently say that the kid must really be some kind of genius.  No matter what kind of question was thrown at him, he could answer it perfectly.  Just like what he did just now.  "You can go back to your seat."

Luo Yan smiled at Teacher Wu and then walked back to his seat.  After sitting down, he, again, pretended to be diligently listening to the teacher's lecture.  Math had always been his best subject.  So even if he didn't listen to the teacher, he'd still be able to answer any question he would throw at him.  Like what he just did earlier.
