When it comes to learning, Su Nan will never refuse.

She also didn't realize how false it was for a person whose grades were often on an equal footing with her to say that he was "quite a problem".

If his Song Tingchuan problem is still quite big, the group of people who have worked hard outside will not live.

I have to say that Song Tingchuan is indeed a one-hit kill, and he easily finds the right entry point.

However, Song Tingchuan is not the only one who finds the right entry point.

Our classmate Zheng Junming took advantage of the break to carry his homework.

"That squad leader, I、I have two questions here.,No.、Not very good"

Song Tingchuan was about to laugh at this girl.

Come back

Without waiting for Su Nan to speak, Song Tingchuan took the first step to wave at Zheng Junming

"Come, Xiao Ming, our class adults need to rest, I'll help you."

Zheng Junming has a gentle temper on weekdays and is very popular with passers-by, and the people in the class give him the nickname "Xiao Ming".

Who let Xiao Ming, a child everywhere in the textbooks from childhood to adulthood.

Song Tingchuan secretly gritted his teeth.

Xiao Ming's official partner is Xiaohong, this person still wants to get involved with Su Nan, don't even think about it.

Not to mention the door, the windows are all welded to him.

Zheng Junming""

Why is it Brother Sichuan again

It is said that men know men best, if Zheng Junming couldn't see that Brother Chuan was deliberately obstructing him from chasing people at this time, he would have liked Su Nan for so many years.

, rival in love.

Hmph, the topic is the topic.

Zheng Junming pointed to a math problem and asked Song Tingchuan with a good attitude

"Brother Chuan, this."

Don't ask him why he has a good attitude, just ask Su Nan watching from the side.

Since you are here to seek advice with an open mind, you must have an attitude of seeking advice with an open mind.

Song Tingchuan couldn't see Zheng Junming's careful thoughts, so he just wanted to throw Su Nan out.

After thinking about it, Song Tingchuan said to Su Nan without raising his head while reviewing the question

"Squad leader, help pour a glass of water, I'm a little thirsty."

Anyway, Su Nan's left hand can be used as his right hand, and things like pouring water can be done with one hand.

Song Tingchuan was thinking about it, and Zheng Junming on the side stood up and accused Song Tingchuan

"Brother Chuan, the squad leader's hand is injured, how can you summon the patient?"

After the accusation, he didn't look at Song Tingchuan's dark and gloomy face, and turned his head to Su Nan

"Squad leader, I'll help Brother Chuan pour water, you have a good rest."

Su Nan smiled and didn't say anything, accepting Xiao Ming's kindness.

Song Tingchuan""

The pen in his hand was about to be broken for him.

This wolf cub is not small

Zheng Junming quickly finished pouring water and came back, and he was still very friendly to Song Tingchuan

"Here, Brother Chuan, no thanks."

Song Tingchuan""

I thank you second uncle

Song Tingchuan held back the fire in his belly.

However, the nest fire is the nest fire, and the topic Song Tingchuan is still very detailed, and he deliberately found the easiest way to explain it to Zheng Junming, I just hope that this product will be clarified and get out quickly.

As a result, Zheng Junming pretended to be stupid

"Hey, Brother Chuan, why didn't I understand this step to this step?"

Oh, that's a theorem from the book.

So Song Tingchuan patiently wrote the theorem carefully on scratch paper for him.

Zheng Junming scratched his head

"No, Brother Chuan, I know this theorem, but I don't know how it came about."

Song Tingchuan""

The co-author has to let him derive the theorem again, right?

Yes.

This kid is really good.

So Song Tingchuan began to seriously give examples to demonstrate.

Then Zheng Junming continued to give counter-examples to refute.

Song Tingchuan was not a person with good patience, and his face was inevitably a little ugly when he was annoyed now.

Zheng Junming looked at Song Tingchuan cautiously

"Brother Chuan, do I have too many questions?"

A real woman's watch

Song Tingchuan was so angry that he vomited blood.

A big man, who is this aggrieved tone to show?

Before Song Tingchuan could speak, Su Nan on the side began to pick up the red pen with his left hand to help draw in circles.

"Look here, this theorem has a premise, and the counterexample you just now is not under this premise."

Zheng Junming almost jumped up with joy, and while listening to Su Nan's lecture, he nodded seriously, and did not forget to praise it

"I see, thank you, squad leader"

Song Tingchuan""
