Rebirth 90 with space to raise cubs

Just when Xu Dan was at a loss and was about to close her eyes and pretend to sleep, a familiar voice sounded beside her.

"Student Xu Dan, you haven't finished yesterday's question, so move one in."

Xu Dan moved inside as if he had received an amnesty, thinking that Uncle Zhou came too timely.

The surrounding students participating in the Mathematical Olympiad are talking about it.

"Hey, isn't Teacher Zhou a physical education teacher? Can he solve Mathematical Olympiads?"

"You don't understand this. Which teacher is easy to enter the No. Middle School?"

"I don't dare to think so, Brother Sledgehammer...hehehe..."

"Whether it will or not, you will know if you see it. Maybe you can follow along to learn. I think Mr. Zhou is a literate one."

The students in the front and back rows nodded in unison, and looked towards Zhou Zhengan and Xu Dan.

Zhou Zhengan took out a Mathematics Olympiad book from his bag in preparation, turned to the place where he had bookmarked before, pointed to a certain question and asked, "I asked you to go back and think about it for yourself yesterday. Have you come up with an idea for solving the problem?"

Xu Dan glanced at the question, isn't this what they said before?
Not knowing why, he glanced at Zhou Zhengan, and nodded cooperatively, "I think about it, I already have a general idea to solve the problem, but I don't know if it's right."

A few people gathered around and listened with gusto. Even Niu Tao, who initially suspected that Zhou Zhengan was deliberately standing between him and Xu Dan, couldn't help but listen carefully and began to think.

Except for some children with motion sickness who couldn't stand it and found an open place to sleep, everyone else felt that they had benefited a lot from the journey.

In addition, Xu Dan's progress and comprehension also made the heaven's favored ones present feel a sense of crisis.

Obviously when she first entered the Mathematical Olympiad class, she still didn't know anything about the Mathematical Olympiad questions, and the methods of solving the problems were all the most basic. After how long it took, some of the people present who could be said to be her seniors began to feel ashamed.

Zhou Zhengan looked around, seeing that he had achieved what he wanted, so he stopped pulling Xu Dan to give a lecture.

He slightly bent down and leaned into Xu Dan's ear, and said softly: "Our Danya has grown up, and there are boys chasing after him."

I don't know whether it's the warm air from him or the warmth from his body, which made Xu Dan's face turn red and his ears feel hot.

The person who happened to cause trouble fell asleep with his chest folded after he finished talking to her, and his eyes that seemed to see through everything were gently closed, which made Xu Dan heave a sigh of relief.

Even so, the little heart was still beating non-stop.

She quickly glanced at the person who was sleeping next to her. The person sitting beside her was a little different from when she first met.

At that time, he was as black as coke, and he was afraid that black people from Africa would be shot at the ground, and the pores on his face would be pierced with needles.

Now after deliberate maintenance, the skin on the face is not only as smooth as a boiled egg, but it can be regarded as a normal face anyway.

Xu Dan passed by his window several times and caught a glimpse of him putting on a facial mask, which was quite delicate.

It was obviously an important competition, but because the person who accompanied the exam was replaced by Zhou Zhengan, after the whole session, except for the exam time, Xu Dan was thinking about him all the time, like a demon.

On the way back, Xu Dan looked at Zhou Zhengan, who was sitting next to her in a familiar way, and his mind was still in a daze.

If it was an accident when Zhou Zhengan went there, and it was still like this when he went back, Niu Tao immediately realized that Zhou Zhengan did it on purpose!
