Li Chenshuang smiled.

As expected of Brother Aci, so awesome!

"You know all?" Wu Gang looked at Shen Ci who was only eleven or twelve years old and felt that this child was talking big.

Shen Ci nodded lightly.

"Okay, then I will test you. If you pass everything, I will allow you to sleep in my class." Wu Gang decided to educate Shen Ci, a child who talks big words.

Shen Ci nodded and looked at Wu Gang firmly.

Wu Gang was shuddered by Shen Ci's eyes.

This kid is very courageous.

Wu Gang thought so.

Wu Gang is a Mathematical Olympiad teacher and has returned from studying abroad, so he is very knowledgeable about Mathematical Olympiads.

"Okay, I'll write the question on the blackboard and you can solve it."

After speaking, he turned back to the podium, picked up the white chalk from the chalk box and wrote the topic on the blackboard.

The most typical question type is the "chicken and rabbit in the same cage" problem.

I saw the following questions on the blackboard:

"There are 220 chickens and rabbits in total. If all the original chickens are replaced by rabbits, and all the rabbits are replaced by chickens, there will be only 212 legs. How many chickens and rabbits are there?"

As soon as this question came up, some of the students in the audience shook their heads, some frowned, some whispered to each other, and some worked hard to calculate.

Wu Gang looked at the status of the students and then looked at Shen Ci.

Shen Ci just stared at the blackboard blankly, doing nothing.

He folded his hands on his chest and leaned on the chair, looking at ease and contentedly.

Wu Gang smiled in relief.

Sure enough, he is still a child and only talks big words.

If you don’t even calculate, how can you come up with the answer?

Wu Gang put his hands on the podium and looked at Shen Ci with a smile.

"Shen Ci, do you know this question?"

Shen Ci opened his mouth slightly but did not speak yet.

Wu Gang was the first to say: "If you don't know it, the teacher won't blame you. Just listen to the class carefully from now on. Are there any other students who can solve it?"

Shen Ci said: "Rooster 34, Rabbit 38."

Wu Gang was a little shocked by Shen Ci's answer.

"Teacher, I'll do it." It was Chen Yirou who raised her hand and said with a sweet smile.

Wu Gang saw Chen Yirou raising her hand and nodded.

Chen Yirou stood up gracefully and gracefully.

"Chen Yirou, come to the podium and write down your ideas for solving the problem!"

"Okay, teacher." Chen Yirou said and walked towards the podium.

The students all looked at Chen Yirou in unison.

Chen Yirou can feel these eyes.

The proud head is raised higher.

He walked straight to the podium and looked at Shen Ci thoughtfully.

When everyone thought she was very powerful, the graffiti on the blackboard really shocked them.

I saw Chen Yirou drawing a bunch of rabbits and chickens on the blackboard and counting the numbers with her fingers.

Wu Gang really had a headache after watching it.

"Chen Yirou!"

Chen Yirou, who was seriously demonstrating her painting skills, heard Wu Gang calling her.

He stopped writing and looked at Wu Gang in confusion.

"Teacher, is my painting not vivid enough? It would be great if I had colored chalk. I can draw better."

Chen Yirou said slightly depressed.

Wu Gang looked at Chen Yirou's innocent appearance and couldn't bear to blame her.

"Okay, you go back to your seat first!"

Chen Yirou tilted her head in confusion: "Teacher, what's wrong?"

"It's okay, you...just go back to your seat first."

Chen Yirou nodded, returned to her seat and sat down with a smile on her face.

Li Chenshuang only dared to cover her mouth and snicker.

"Students with talents can show off their talents by taking relevant courses later. This is also a specialty!"

Wu Gang smiled and looked at the whole class and said.

Chen Yirou still maintained a dignified smile, but her fists hidden in her sleeves were clenched tightly.

"Teacher, Shen Ci just said an answer, is it correct?" Li Chenshuang raised her hand and said.

Only then did Wu Gang remember his bet with Shen Ci's child.

"Yeah, that's correct. Let's do it! Shen Ci, come up and write down your ideas for solving the problem, and let the classmates take a look at it. How did you do it?"

Wu Gang looked at Shen Ci who was looking down at a book.

Maybe the child's answer is obscure. If I write down the process, the true facts will definitely be revealed.

The corners of Wu Gang's mouth raised slightly.

Shen Ci stood up quietly and walked to the podium.

Take a brand new piece of chalk from the chalk box.

Standing aside and looking straight at Wu Gang.

Wu Gang felt that this kid really couldn’t do it!

"Graffiti?" Shen Ci tilted his head and looked at Wu Gang and asked again.

Wu Gang looked at the blackboard and saw that because Chen Yirou had been doodling just now, there was no place to write on the blackboard.

It's all occupied by Chen Yirou's graffiti.

Chen Yirou lowered her head in embarrassment, pretending not to know anything.

Then I heard Wu Gang shouting: "Chen Yirou, come up and wipe the blackboard!"

Chen Yirou raised her head and looked at Wu Gang pitifully.

Wu Gang was shocked.

What's wrong with this kid? He suddenly looks like this.

Li Chenshuang was speechless.

Isn't it just wiping the blackboard?

As for that?

"Teacher, I'll do it." Li Chenshuang walked up to the podium with a sweet smile and wiped the blackboard with her hands.

Wu Gang also nodded happily.

Finally there is someone who is more obedient.

There are some places where the graffiti is relatively high, and Li Chenshuang can't even rub it by standing on tiptoes.

Shen Ci took the blackboard eraser from Li Chenshuang's hand and helped wipe it.

Li Chenshuang let go and looked at Shen Ci.

"Thank you, brother Aci!" Li Chenshuang said with a smile.

"You're welcome." Shen Ci said calmly.

The atmosphere around me is still relatively mild.

After Li Chenshuang finished wiping, she returned to her seat.

Chen Yirou looked at Li Chenshuang jealously.

Why! If I had gone up just now, I would have been able to talk to Shen Ci.

Thinking like this, I grabbed my clothes hard with my little hands.
