Lin Ran didn't expect Zhu Chengzhuang to work so hard.

When he came back from dinner on the second day of school, Lin Ran saw that he was doing a problem, so he looked down and saw that it was a chemistry exercise book.

"Didn't go to dinner, huh?" Lin Ran asked.

"Go." Zhu Chengzhuang did not look up.

Lin Ran was just about to turn around and sit down, but Zhu Chengzhuang raised his head and frowned, "Sister, ask a question." ”

Lin Ran was stunned.

"Sister?" Lin Ran sneered, what year are you?

“97。” Zhu Chengzhuang said.

"I'm 98, you call me sister?" Lin Ran laughed, stretched out his hand and took Zhu Chengzhuang's exercise book, "Is this brother?" ”

"Poof!" Zhu Chengzhuang looked at Lin Ran and laughed, and then nodded.

Lin Ran's best skill is chemistry.

Having given up the obviously more advantageous liberal arts to come here, it was for the sake of chemistry.

Lin Ran had already done that question.

"I don't know how to do it." Zhu Chengzhuang said.

"The answer is wrong." Lin Ran was simple and clear, gently put the exercise book back on Zhu Chengzhuang's desk, and carefully placed it.

"Huh? Have you asked the teacher? Zhu Chengzhuang frowned.

"Nope." Lin Ran shook his head, "But it's just wrong." ”

"Well, I think it's wrong too, hehe!"

Zhu Chengzhuang laughed a little silly, and Lin Ran couldn't help but laugh too.

"Oh yes, why didn't you sign up for the class? I've heard that there are no people in math and biology yet. ”

"Not interested." Lin Ran said, "I don't like mathematics, and my grades are not good, so I'm afraid of being scolded." Biology, the class teacher's class representative, is not very reassuring. ”

"Chemistry?" Zhu Chengzhuang said, "You are so good at chemistry." ”

"Isn't there someone in chemistry?" Lin Ran thought for a moment and then said, "Moreover, I don't like our chemistry teacher very much. ”

"Okay. I really want to play in front of him, I think the old class is very good, and it should be good to be a class representative for him, but I don't dare to tell him. Zhu Chengzhuang said.

"If you want to be, you can be, what's this!" Lin Ran laughed.
