Principal Ren Jun cleared his throat and looked at all the teachers and students on the playground filled with joy, and even his voice was a little hoarse with excitement.

…………

………… In the afternoon, Zheng Dong was left in the office of the Academic Affairs Office by the teachers of the whole school, and he kept asking questions in turn.

“…… Uh, that ...... Teachers, please stop for a moment...... I know that you are for the good of the school and the whole village, so I will contribute my learning methods, but ...... I have a request, those who are willing to learn my methods in this class must listen to me, and the next class will be handed over to Mr. Zheng...... If only we could start tomorrow!"

"No problem! If you ask me to call me, I won't be able to now, I can also learn first when you teach, and I will teach you next time!"

The light in Mr. Zheng's eyes was about to pop up, and he didn't feel embarrassed at all because he was a teacher to learn things from a seven-year-old child.

Zheng Dong saw the appearance of Mr. Zheng, and had some understanding of his dedication to teaching and educating people, although he also knew in his previous life that he wanted to let people in the village be admitted to the university and go out to dedicate something, but because he didn't have much contact, he didn't know very much, and after this period of contact and understanding, he could feel full of energy for his admiration......

……………

Friday.

There was a scene in the first-grade classroom that Renji Elementary School had never seen since its establishment, not to mention Renji Elementary School, that is, it is estimated that it has not appeared in the whole country since ancient times.

On the podium, Zheng Dong stood next to the lectern that was taller than himself, (if I didn't stand next to him, the children and a few teachers below couldn't see me!) and talked about finger addition and subtraction to the teachers and students below, plus some advanced education methods that he learned when he held a parent-teacher conference for his son in his previous life.

Zheng Dong was talking about spitting and flying, and the teachers and students below listened with red light on their faces (mainly teachers).

......... "Little ...... Teacher, that decimal ...... you said."

Teacher Jia in the second grade didn't understand, and the knuckle decimal rate asked, remembering the requirements of this little guy at the beginning, and hurriedly changed his words......

"This big student! You have forgotten what I said! I repeat the three basic requirements when asking a question: First, raise your hand first when asking a question, and then speak with the teacher's permission. Second, when speaking, the first thing to call is the teacher, and then to speak. Third, use polite language when speaking, please ask, please, please advise...... If anyone forgets anything else, they will go outside and be punished!"

A seven-year-old child looks like an adult, and the teacher and the students below him hide their heads under the table and cover their mouths.

Teacher Zheng looked at Zheng Dong on the podium, and the feeling in his heart was different, this is his own student, and he is the most proud student so far.........

Ren Xiaogao didn't hide his head, his eyes were full of unconvincing, and he kept looking at Zheng Dong on the podium, "Isn't it just counting with finger knots? What's the big deal, I also did well in the exam this time, 91 in Chinese, 89 in mathematics, this time you didn't get the first place in the township alone, what a spirit!"

He does have the capital to be unconvinced, in his last life, Zheng Dong can say that whether it is primary school or junior high school, the ranking has always been below Ren Xiaogao, the results of the two are the same as racing, Zheng Dong will take the 80 test, Ren Xiaogao will take the 81 test, in short, it will be one or two points higher than Zheng Dong every time.

"Classmate Ren Xiaogao!"

Zheng Dong saw the unconvincing in his eyes, it was still that personality, he had been pressing himself all his life, and after he dropped out of school, he dropped out of school after one more semester than himself, and the reason is still not clear to him.

Anyway, I was uncomfortable being pressed by you in my last life, and I want to press you uncomfortable in this life!

It's not that Zheng Dong is stingy, it's that Ren Xiaogao is a little cheap, every time the exam results come out, he will be embarrassed in front of Zheng Dong, because the two have fought in this matter, and they have been beaten by the adults of his family.

"What do you want me to do?" he dragged his head up.

"Are you not convinced? Let's compete now, let our teacher come up with two sets of the same questions, let's see who answers them the fastest and most accurately, if I lose, I will give you the reward of 30 catties of white noodles, if you lose, you will have to listen to me in the future, you have to do whatever I tell you to do, and you are not allowed to resist, until one day you surpass me! Let these teachers in our school testify, do you dare?"

With a look of contempt, I'm going to despise you strategically, tactically...... The same contempt for you!hehe...... If you don't accept it, you will come back in a while!

“… I ......!" Ren Xiaogao was a little scared, and suddenly felt that Double Hundred was like a high school wall, and he couldn't climb it at all.........

“…… You... Be... At... Scared?"

Zheng Dong's words approaching step by step completely ignited Ren Xiaogao's anger.

"That's what we've learned...... What you haven't learned doesn't count!"

Ren Xiao stood up suddenly, his face flushed.

Zheng Dong also had to admire him, after all, he was only seven years old, so he was so kind, it is said that with a personality like him, he should not be in his forties like himself in his previous life, and he has achieved nothing!

"Good...... I have a request, it can't be too simple, so it's difficult for the two of us to tell who is fast and who is slow!" Zheng Dong added another one, he knew that Teacher Zheng's temper was very good to each of his students, just like when he had a conflict with Ren Xiaogao in his previous life, he would try to resolve it without hurting both sides.

"Okay...!" Ren Xiaogao agreed in a tugging manner.

……… In the academic affairs office, it took several teachers almost an hour to walk into the classroom with two blank pieces of paper, there is no way that the two students are the best top students in their own school, and now the school's gratitude to the first grade and Zheng Dong and their few classmates who participated in the competition, there is Zheng Dong's factor in it, so the two of them are allowed to ask, not to mention that Zheng Dong is expected to go to the county next Tuesday to win glory for the school. Who will mess with him at this time, he is the key person in whether Renji Primary School can be promoted to a key primary school.........

Several teachers and the principal Ren Jijun came to the classroom and followed suit.

"This time the two of you are acting as a manifestation of active learning, and I hope that other students will also have the courage to participate in it, so that our school's grades will get better and better!"

After the principal Ren Jijun finished speaking, he nodded and motioned to Teacher Zheng to start sending the topics discussed by several teachers to the two of them.

Math problem: Xiao Ming ate one steamed bun yesterday morning, ate three at noon, ate the sum of morning and noon at night, and ate one less this morning than yesterday noon, how many steamed buns did Xiao Ming eat from yesterday morning to this morning?
