It didn't take Feng Jiao long to solve the problem after seeing how Gao Longwei had solved the other ones. It was not hard anymore. She had figured out the method, and now it was easy to just go through the problems.
She stretched backwards with a yawn, like a cat, and then plopped forward, onto her belly.
"I'm so tired!" she whined spoiledly.
Gao Longwei could instantly tell that Feg Jiao had indeed consumed all of her seemingly infinite stash of energy. Even though it seemed like it might have gone on forever, it ended pretty soon.
Math was exhausting by itself, let alone going through seven years of syllabus and then starting on the year you were in. It was so hard that Feng Jiao wanted to cry at least ten times in between.
Gao Longwei was definitely strict, but he often gave into Feng Jiao's demands without much of a fight. He didn't really think that she would be able to stick it out, but she did. Gao Longwei was incredibly proud of her for getting through all of that.
