Everyone knew they were going to have a new member on their team.

Although I haven't met this new member, everyone can roughly guess that the new member should look like a math bully, wearing glasses, dressed modestly, and more introverted - just like the rest of the math class.

Now, however, all of these imaginations have been overturned.

He had a good skin, broad shoulders and long legs, and was dressed in black, with only a conspicuous circle of white gauze wrapped around his right hand.

His eyebrows were cold, and his expression was full of tiredness that he couldn't hide.

Combined with the fights just revealed, smoking, is completely a very social social brother.

Just before everyone could recover from the shock, "Brother Society" spoke again.

He nodded politely at everyone: "I'm a freshman in the Department of Finance, He Sibai." ”

In terms of identity, He Sibai is a student of the outer courtyard who is two years younger than them.

In terms of words and deeds, this newcomer is completely different from them.

Alien to them.

All of the people present were up-and-coming rookies in the mathematical world, and they were already a little young and arrogant.

One boy made no secret of his disdain and laughed "heh".

He looked at Teacher Zhou: "Teacher, today is not April Fool's Day, right?" ”

Of course, Teacher Zhou understood his meaning, and said, "Liu Jian, don't underestimate people. He has strong mathematical skills. ”

Liu Jian smiled: "Teacher, who here is not strong in mathematics?" Besides, we have a lot of talents in our college, so why do we have to find a freshman? ”

Another boy with glasses echoed: "Teacher, the school attaches great importance to this competition, this student is only a freshman, it is inevitable that he is inexperienced, if there is any unexpected incident in the process of team competition, it will affect the result of the competition." ”

On the surface, he was thinking about He Sibai, but in fact, he still didn't believe He Sibai's contempt between the lines.

Although the rest of the students didn't speak, they also cast all kinds of suspicious glances at He Sibai.

It's full of clothes and snow.

He Sibai was still expressionless, obviously not taking the ridicule to heart.

He pressed Teacher Zhou's arm and signaled that Teacher Zhou didn't need to say more.

Then he spoke, his tone was still low and cold, but with some impatience: "Discussion, I can't keep up with the progress, I'll leave." ”

Concise, calm and solid promises, without a word of nonsense.

It can be regarded as giving these top students an explanation.

Teacher Zhou seemed to have expected He Sibai to say this. He sighed inaudibly and waved at everyone: "Is this satisfying to you?" Alright, let's all go to the classroom. ”

Everyone looked at each other and walked to the classroom without saying a word.

The seminar classrooms are relatively small, with only four long desks. It is placed in the shape of "mouth", which is convenient for people participating in the discussion to gather and discuss.

Teacher Zhou naturally occupied a chair by himself, and the other four boys sat down in pairs. There was only one girl left, because she finally entered the classroom and there was no room to choose a seat, she hesitated for a moment, but still sat down next to He Sibai.

"My name is Lu Xiao. Take care of me in the future. She smiled at Hesbai.

Not to mention anything else, He Sibai's appearance can be regarded as a first-class outstanding. It's easy to make girls of this age feel good.

He Sibai nodded at her: "Hello." ”

Mr. Zhou gave all the students some A4 papers for verification. Then the big screen was turned on and the prepared courseware was played.

Teacher Zhou also deliberately emphasized: "Today is the first day, and I have prepared some basic questions. ”

Everyone looked at it, and in the courseware, it was clear that they were all past questions.

None of them are basic.

Lu Xiao lamented in his heart that Teacher Zhou was too ruthless, and at the same time lowered his head relentlessly.

As soon as she opened her pencil case and took out a pen, she felt a gaze next to her.

She looked up, just in time for He Sibai's gaze.

The boy coughed a little embarrassedly: "Can you lend me a pen?" ”

Wow, I didn't bring a pen, it's so chic.

Lu Xiao nodded, took another pen and handed it to him.

He Sibai took it: "Thank you." ”

All morning, Lu Xiaodu devoted himself to math problems. When she looked up and rested, she noticed that He Sibai rarely used her pen.

Perhaps because of the inconvenience of He Sibai's hands, more often than not, he leaned back lazily on the back of his chair, looking tired, staring at the question on the big screen.

On the other hand, everyone else is struggling to write. When he is excited, he will argue loudly with his table mates about right and wrong.

Maybe these questions are really too difficult for He Sibai.

Lu Xiao sighed in his heart, maybe tomorrow, He Sibai will retreat and stop coming.

The questions on the big screen are one after another, and it comes to the final finale.

Teacher Zhou said: "The last question is the most difficult question in the past ten years, and interested students can try to challenge it, or they can leave the class directly - everyone is tired after sitting all morning, right?" ”

Lu Xiao clearly heard Liu Jian next to him let out a cold snort.

Then he said to himself: "Yes, some people must be tired after sitting all morning. ”

It's not high, but it happens to be the one that everyone in the classroom can hear.

He Sibai was still staring at the big screen, as if he hadn't heard it.

Liu Jian was bored with himself, lowered his head, and also studied the topic.

Ten minutes later, Lu Xiao heard the sound of a stool being dragged away beside him—it was He Sibai who stood up.

He Sibai bent down, returned the pen to Lu Xiao, and thanked him: "Thank you." ”

As if he was worried about affecting the rest of the people's studies, the boy specially lowered his voice, and his already deep voice sounded a little more hoarse.

It's so sultry that Lu Xiao couldn't help but have hot cheeks: "No, you're welcome." ”

He Sibai turned around and said goodbye to Teacher Zhou: "Teacher, I have to go to the hospital to change the dressing in the afternoon, so I will leave first." ”

Teacher Zhou nodded in agreement. But the rest of the classmates were already snickering.

Liu Jian was proud, and he didn't know who he was talking to: "Look, I can't bear it, I ran away, right?" ”

As soon as Liu Jian's words fell, at this time, He Sibai suddenly whistled.

The whistle was sharp and flirtatious, and all the students subconsciously raised their heads.

I saw He Sibai raise his middle finger at Liu Jian, with a bright and mocking smile, and made a "pen" lip shape.

Perhaps because he was no longer constrained by "classroom discipline" after class, He Sibai finally stopped hiding his arrogance.

He looked at Liu Jian's eyes dark, with a strong oppressive nature.

The atmosphere suddenly became tense.

Liu Jian was so angry that his face was red and his neck was thick, but he was cowardly, knowing that he was tough and rigid with He Sibai, who was full of anger, and he would definitely not take advantage.

But he felt that He Sibai's move made him lose face in front of everyone, so he lowered his head and scolded the ground in a low voice.

It's like a resentful woman, it's funny.

Teacher Zhou coughed very coincidentally, breaking the deadlock in the classroom.

The air seems to be flowing again.

He Sibai returned to his usual expression, smiled, and turned to leave.

Liu Jian also closed his mouth in amusement.

After the turmoil, all the students in the classroom are still studying. Unfortunately, after another half an hour, no one made it.

Teacher Zhou yawned: "Okay, take it back to study after class, I'll be here first today." Remember to attend tomorrow's meeting on time, and the school leaders will come to see it. ”

The paper was full of clueless calculation and reasoning, and Lu Xiao put down the pen very unwillingly and began to pack up the stationery.

Her peripheral vision caught a glimpse of the scratch paper that Hesbeth had not taken with him.

Driven by curiosity, Lu Xiao tilted his head and looked at the scratch paper left by He Sibai.

His scratch paper is messy, every letter and number is crooked, and it is believed that the owner of this paper is not used to writing with his left hand.

She followed these "ghost drawing talismans" and looked at them patiently, and the values that appeared at the end of the paper made Lu Xiao couldn't help but feel excited.

Then he subconsciously let out a low shout: "He Sibai, the argument is out!" ”

As soon as these words came out, the classroom, which was originally filled with low discussions, fell silent in an instant.

The change came unexpectedly. Liu Jian, who was frowning and biting his pen and looking at the topic in a daze, raised his head suddenly, with a stunned face that had not yet reacted.

"Are you mistaken?" He stood up abruptly and scooped up the scratch paper on the table.

Liu Jian's gaze quickly moved downward, and he browsed ten lines at a glance.

When he saw the end, he was also silent with mixed feelings.

The idea of solving the problem is clear and organized.

And this way of solving the problem is obviously a knowledge point beyond their undergraduate knowledge.

If he's not mistaken, this is something that can only be learned in a doctoral program, linear filtering.
