077 Equal Difference Series

Xia Shan and those two girls are very eye-catching.

For Mr. Lin, his students are all good children, and they have been messing with these so-called people in society for a long time before they become what they are now.

As a result, this woman, who seemed to be intellectual, gentle and gentle, also showed a gentle resistance to the three of them.

In the face of Teacher Lin, those students were obviously not very adaptable.

This teacher is beautiful and gentle, and he is sincere to them.

Therefore, even if it is not in line with their wishes, it is difficult for them to have any resentment against this real teacher.

"I heard that everyone is going to have a dinner, is it okay to bring the teacher along? Recently, the outside is not complete, I will send you home after eating?"

The students looked at each other, and in the end, their eyes quietly focused on Song Xun.

Teacher Lin naturally knew that these little cats were greasy among the students, so he looked at Song Xun with gentle eyes.

Song Xun didn't feel very comfortable.

This is the only person he has encountered in his limited life that he finds difficult to deal with.

For him, gentleness is the most powerful weapon.

Glancing at Xia Shan, Song Xun's eyes flickered a little, and he sighed halfway through.

Since Mr. Lin is here today, it can be regarded as this guy's luck...... Song Xun chose to let Xia Shan go.

When the people arrived, it was almost a hotel.

Song Xun arranged to start serving.

At the dinner table, the female students who had been chatting with Xia Shan before have restrained a lot. In front of the teachers who are truly respected by them, there are really few people who can laugh wantonly without skin and face.

On the contrary, the two girls who came with Xia Shan, there was no lack of meaning to get drunk Xia Shan at the dinner table.

They don't know these people, they are here just for Summer Mountain.

Although Song Xun plans to let Xia Shan go, some small difficulties are indispensable.

The young man is full of spirit, and if he has a vengeance, he has to take revenge at that time.

"Brother Shan, come, I'll toast you. Song Xun came to Xia Shan with a wine glass full of liquor.

Just because most of the students have converged does not mean that they have also converged.

As the demon king of the mixed world in the school, he is a representative of deviance.

Otherwise, how can we get the followers of those simple students who are not deeply involved in the world?

After all, you can do things without looking at the faces of adults, how cool it is~

Xia Shan took the first cup, which was within his limited amount, which was acceptable.

"It's done!" Song Xun is young, the amount of alcohol is not bad, and his body can resist hard.

Xia Shan smiled and drank it all.

The two girls sitting next to him looked at the heroic Summer Mountain, their eyes full of little stars.

This is a man~

After drinking all one cup, Song Xun obviously didn't plan to let go of Xia Shan, and directly took another cup for himself to fill it up, this is to have two cups together, "Good things come in pairs!"

Summer Mountain can't drink anymore, but ...... It is impossible to admit defeat just like that.

Xia Shan looked at Song Xun and said, "Why don't you say all the rest of the words first?" or I'll help you say it?"

"Oh, then tell me about it?" Song Xun would not give up the initiative to his opponent.

"Let's be brief, are you going to drink with me from one to ten?"

"That's nature, it's perfect......"

"Well, I'll ask you a question that is within your ability, and if you can answer it, I'll drink with you, and drink until everything goes well. Natsuyama showed the devil's tail.

Song Xun was at a loss, and responded, "Okay!"

"Give you three seconds...... One to ten is a series of equal differences, isn't it? It's easy to sum a series of equal differences, right? Say, how many glasses of wine do we have to drink?"

Song Xun's small eyes were full of big question marks.

This kind of thing is a blind spot in his knowledge reserve......

If he can go to school well, then he will be a fart!

Teacher Lin, who was sitting on the side, as a professional math teacher, would not laugh in the face of such a primary school problem...... Unless you can't help it.

Looking at Xia Shan's handsome appearance, Mr. Lin felt much more pleasing to the eye for a while.

Xia Shan sighed and patted him on the shoulder, "Study hard, otherwise you won't be able to persuade him to drink." ”

Teacher Lin covered his mouth and smiled, "goose goose goose" and let out a forcibly suppressed laughter.

Laughing and laughing, but suddenly coughing.

Frowning, Teacher Lin raised his eyes and glanced around the room, then planned to get up and go out.

Song Xun hurriedly looked for the bottom of the stairs, and hurriedly asked with concern, "What's wrong with Teacher Lin?"

Teacher Lin opened his mouth and said in a soft and slightly hoarse voice: "It's nothing, I'll pour a glass of boiled water, I have to take medicine for the past two days when I have a cold." ”

"I'm with the teacher!"

Song Xun escaped from this hell on earth.

Everyone is playing outside, why do you still talk about things in class?

It's already so hard to go to class, why do you have to recall such a horrible thing during the summer vacation?

Walking out of the door, Mr. Lin looked at Song Xun beside him, with some helplessness in his eyes, "The summation formula of the equal difference series is S."

=(a1+a

)

/2, remember. ”

"Yes~" Song Xun replied listlessly.

"Yo! where did the beauty come from~"

A silver evil voice aroused Song Xun's vigilance.

Song Xun and Teacher Lin looked at the people, Teacher Lin didn't know much about this kind of scene, but he also felt that it might be a little troublesome.

As for Song Xun, he chuckled even more in his heart.

I wanted to look for him and couldn't find it, but at this time he appeared.

Being favored by this big bald head, the teacher is afraid that he will be in trouble.

Immediately, Song Xun hurriedly took two steps forward and slightly pressed against Hu Jianzhong's big belly, "**, this is my teacher's ......"

Hu Jianzhong lowered his head, looked at the white and thin Song Xun in front of him, and looked at Song Xun's hands again.

Song Xun withdrew his hand knowingly.

Hu Jianzhong said: "What do you mean kid? What kind of person am I?"

"Yes, yes, not that kind of person. While speaking, Song Xun turned back to Teacher Lin and said, "Teacher, you go back to the private room first, and I'll find you water." ”

"Wait!" Hu Jianzhong pushed Song Xun away, his eyes looking up and down Teacher Lin's body.

The women who come to the bar generally don't have the kind of bookish atmosphere that fills the whole body, even some female students.

Mr. Lin's unique intellectual and cultural atmosphere instantly aroused Hu Jianzhong's desire.

**I don't have much of a hobby, I just like to communicate with all kinds of beauties and exchange life.

"Since it's your kid's teacher, let's have a few drinks together, okay?"

"Yes, yes, yes!" the little brother behind him immediately began to echo each other, and at the same time went to arrange the box.

"**!**!" Song Xun was a little anxious, "My teacher can't drink!"

"Then you drink it for her?" Hu Jianzhong glanced at Song Xun with slanted eyes.

Song Xun gritted his teeth, "**Since you are interested, the little brother will naturally accompany you!"

"Okay, let's go!"

Song Xun asked with some hesitation: "Then, can my teacher go back first?"

"How can that be done?" Hu Jianzhong's eyes widened, "You drink for her, you drink for her! She herself must also be! I admire these cultural people the most, and I need to communicate more!"

Although Mr. Lin is not very exposed to these dark sides, he is not a young child who has just entered society.

Her beautiful face looked a little overwhelmed, this kind of thing is not something she is good at dealing with.

"What should I do?" Song Xun's mind turned sharply.
